1
00:00:00,000 --> 00:00:07,540
I know it looks like we have fun on this show, but we spend weeks and sometimes months planning how to do our myths safely.

2
00:00:07,540 --> 00:00:10,540
So please, don't try this at home.

3
00:00:15,180 --> 00:00:17,340
On this episode of Mythbusters,

4
00:00:19,220 --> 00:00:22,020
it's an evolution revolution.

5
00:00:23,940 --> 00:00:27,220
As the team takes five fan favorites and

6
00:00:28,160 --> 00:00:31,680
and focuses on a fascinating new facet for each.

7
00:00:33,180 --> 00:00:37,840
First, Adam and Jamie give Waterheater Rocket a whole new story.

8
00:00:38,620 --> 00:00:43,860
Then they think outside the box with the Hollywood car classic hanging there.

9
00:00:45,460 --> 00:00:50,340
Meanwhile, Carrie Grant and Tori pick a cool coda to liquid nitrogen.

10
00:00:50,780 --> 00:00:51,900
Cups are on their way.

11
00:00:52,200 --> 00:00:57,580
Then they take a tangent with Bend a bullet, turning it into the myth of the corner shot.

12
00:00:58,480 --> 00:00:59,280
Mama like it.

13
00:00:59,680 --> 00:01:06,280
And finally they focus on the missing link of snow plow split with some rocket powered evolution.

14
00:01:15,780 --> 00:01:17,120
Who are the Mythbusters?

15
00:01:18,360 --> 00:01:19,320
Adam Savage.

16
00:01:19,380 --> 00:01:20,640
I'm ready to go, man.

17
00:01:21,120 --> 00:01:22,320
And Jamie Heinemann.

18
00:01:24,360 --> 00:01:28,200
Between them more than 30 years of special effects experience.

19
00:01:30,120 --> 00:01:30,800
Joining them,

20
00:01:31,760 --> 00:01:32,600
Carrie Byron,

21
00:01:34,560 --> 00:01:35,720
Grant Imahara

22
00:01:37,260 --> 00:01:38,520
and Tori Bellachy.

23
00:01:39,880 --> 00:01:41,320
They don't just tell the myth.

24
00:01:42,060 --> 00:01:43,960
They put them to the test.

25
00:01:49,320 --> 00:01:52,320
Myth Evolution. What are we testing Darwin?

26
00:01:52,320 --> 00:01:54,000
Darwin doesn't need our help.

27
00:01:54,000 --> 00:01:59,320
This episode is called Myth Evolution because it has to do with the fact that every time we air a new episode of Mythbusters,

28
00:01:59,320 --> 00:02:04,200
hundreds, thousands of fans write to us to comment on that episode.

29
00:02:04,200 --> 00:02:06,720
Yeah, a lot of them just want to tell us what we got wrong.

30
00:02:06,720 --> 00:02:11,000
Some of them want to say things we screwed up. Others want to suggest other tests we missed.

31
00:02:11,000 --> 00:02:12,920
And some of them want to say things we screwed up.

32
00:02:12,920 --> 00:02:15,000
Others want to suggest other tests we missed.

33
00:02:15,080 --> 00:02:16,800
And some of them want to say things we screwed up.

34
00:02:16,800 --> 00:02:19,280
Others want to suggest other tests we missed.

35
00:02:19,280 --> 00:02:23,080
And some of them just want us to go down different tangents of stories we've already done

36
00:02:23,080 --> 00:02:25,800
because they have other ideas about things we could explore.

37
00:02:25,800 --> 00:02:27,680
Okay, well, what's on the roster?

38
00:02:27,680 --> 00:02:32,560
Well, we do have an evolution of the hanging on the roof of a car story.

39
00:02:32,560 --> 00:02:35,000
But first up is Water Heater Rocket.

40
00:02:36,000 --> 00:02:39,600
In one of the all-time most memorable myth-busting moments,

41
00:02:40,960 --> 00:02:44,480
Adam and Jamie confirmed that in a worst-case scenario,

42
00:02:45,000 --> 00:02:49,080
a water heater could blast through your roof like a rocket.

43
00:02:49,080 --> 00:02:51,520
Did you know what was lurking in your basement?

44
00:02:52,480 --> 00:02:57,480
But fansite message board murmurings have moved this myth to the next level.

45
00:02:57,480 --> 00:02:58,520
Literally.

46
00:02:58,520 --> 00:03:02,600
Not only have you demanded a two-story extension to the story,

47
00:03:02,600 --> 00:03:06,920
you also want to know exactly how high a water heater can fly.

48
00:03:08,200 --> 00:03:10,680
So how are we evolving Water Heater Rocket?

49
00:03:10,680 --> 00:03:15,880
Well, last time we successfully demonstrated that a water heater under the worst-case scenario

50
00:03:15,880 --> 00:03:20,200
can actually behave just like a rocket and shoot up through the roof with one story house.

51
00:03:20,200 --> 00:03:21,840
And a lot of fans complained about that.

52
00:03:21,840 --> 00:03:27,000
They said they lived in two-story houses and that simple fact might have changed our results.

53
00:03:27,000 --> 00:03:31,640
Okay, well, let's build the two-story house and do it to California Code, see what happens.

54
00:03:31,640 --> 00:03:35,440
Now, hold on. Before we do that, I think we actually have some important questions to answer

55
00:03:35,440 --> 00:03:39,440
in terms of the energy involved, the speed the hot water heater left the ground at,

56
00:03:39,440 --> 00:03:41,040
and the total height that it went to.

57
00:03:41,040 --> 00:03:44,720
As I recall, we got up to about 500 feet on that last one.

58
00:03:44,720 --> 00:03:47,040
Yeah, it turns out there's some dispute about that.

59
00:03:47,040 --> 00:03:49,200
And because it's a burning question of the fans,

60
00:03:49,200 --> 00:03:53,600
I think we should answer it by setting a hot water heater out with nothing for it to go through,

61
00:03:53,600 --> 00:03:57,040
nothing in its way, and accurately see how high it goes.

62
00:03:57,040 --> 00:03:57,920
I love it. Let's go.

63
00:03:59,120 --> 00:04:02,960
So it's Water Heater Rocket Part 2 in two parts.

64
00:04:02,960 --> 00:04:05,280
Can the rocket make it through two stories?

65
00:04:05,840 --> 00:04:07,280
This place is great.

66
00:04:07,280 --> 00:04:08,240
Works for me.

67
00:04:08,240 --> 00:04:12,560
But before that, the boys need that controversial altitude answer,

68
00:04:12,560 --> 00:04:16,720
which has brought them to an all-new detonation destination.

69
00:04:16,720 --> 00:04:23,280
I'm standing smack dab in the middle of 240 square miles of methane-producing landfill,

70
00:04:23,280 --> 00:04:26,080
actually waste management's ultimate landfill, to be exact.

71
00:04:26,080 --> 00:04:30,080
And if you throw some trash out in San Francisco, this is where it ends up.

72
00:04:31,120 --> 00:04:34,960
It's the perfect place to launch this stripped-back household heater

73
00:04:34,960 --> 00:04:38,880
and confirm once and for all how far and fast it goes.

74
00:04:40,080 --> 00:04:44,400
This still can right here is actually the pressure vessel at the heart of your average

75
00:04:44,400 --> 00:04:46,320
household hot water heater.

76
00:04:46,320 --> 00:04:50,800
We are going to pressurize it until it explodes in hopes that watching it explode like this

77
00:04:50,800 --> 00:04:53,600
will illuminate some of its performance characteristics.

78
00:04:53,600 --> 00:04:58,400
And the recipe for that all-important explosion is the same as last time.

79
00:04:58,400 --> 00:05:04,480
Seal off all of the safety release valves, give it a hot rod paint job, add water,

80
00:05:04,480 --> 00:05:09,760
turn on the power, add some blankets to hurry the heating, and sit back and wait.

81
00:05:09,760 --> 00:05:11,760
What's the butter zone for the explosion again?

82
00:05:11,760 --> 00:05:14,320
About 350 psi.

83
00:05:14,320 --> 00:05:14,720
All right.

84
00:05:15,360 --> 00:05:18,880
This test is all about recording the height and the speed that the water heater achieves

85
00:05:18,880 --> 00:05:19,840
when it goes off.

86
00:05:19,840 --> 00:05:23,040
We've got a video camera aimed at the whole scene,

87
00:05:23,040 --> 00:05:28,480
and we should be able to estimate how high the thing is going if we can see it.

88
00:05:28,480 --> 00:05:30,880
Okay, we're at 150 psi.

89
00:05:30,880 --> 00:05:32,000
Halfway there.

90
00:05:32,080 --> 00:05:34,560
Everybody into your safety positions.

91
00:05:34,560 --> 00:05:36,560
We're in the red zone.

92
00:05:36,560 --> 00:05:37,920
I'm getting a prediction.

93
00:05:37,920 --> 00:05:38,400
Hold on.

94
00:05:38,400 --> 00:05:39,440
It's coming in.

95
00:05:39,440 --> 00:05:40,560
It's coming in.

96
00:05:40,560 --> 00:05:40,960
All right.

97
00:05:40,960 --> 00:05:45,440
I predict that we are slowly going to watch pressure buildup on a computer.

98
00:05:45,440 --> 00:05:47,040
200 psi.

99
00:05:48,640 --> 00:05:49,760
We're getting close.

100
00:05:50,320 --> 00:05:54,480
While we stare at a steel can that does nothing for maybe 40 minutes.

101
00:05:54,480 --> 00:05:55,280
Okay, folks.

102
00:05:55,280 --> 00:05:57,360
We're up to 300 psi.

103
00:05:57,360 --> 00:05:58,320
Hold on to your hats.

104
00:05:59,200 --> 00:06:02,240
And then the steel can is going to disappear and I'm up to smoke.

105
00:06:02,240 --> 00:06:05,040
315 psi.

106
00:06:05,040 --> 00:06:06,880
And Jamie Heinemann is going to make this sound.

107
00:06:10,080 --> 00:06:10,960
That's my prediction.

108
00:06:16,000 --> 00:06:17,760
It takes so long to come down.

109
00:06:17,760 --> 00:06:18,320
Why is it?

110
00:06:19,360 --> 00:06:20,000
Here it comes.

111
00:06:24,880 --> 00:06:26,240
I never get tired of that.

112
00:06:26,240 --> 00:06:27,680
No, hence the coming down.

113
00:06:27,680 --> 00:06:28,880
That's the fun part.

114
00:06:28,880 --> 00:06:30,000
Let's go check it out.

115
00:06:30,000 --> 00:06:30,320
All right.

116
00:06:30,320 --> 00:06:31,200
Let's do it.

117
00:06:31,200 --> 00:06:34,000
This is what I love about hot water heaters.

118
00:06:34,000 --> 00:06:36,080
I'm going to start referring to them as old faithful.

119
00:06:37,440 --> 00:06:40,880
A lot of times when we're trying to get stuff to fail, it's like a one in a million shot.

120
00:06:43,280 --> 00:06:45,760
It's like a one to one shot with these hot water heaters.

121
00:06:46,640 --> 00:06:46,960
Poop.

122
00:06:47,280 --> 00:06:56,160
Consistent calibrated carnage means atoms in myth buster heaven.

123
00:06:56,960 --> 00:06:59,520
But what about the all important flight data?

124
00:07:00,800 --> 00:07:01,680
What do we got?

125
00:07:01,680 --> 00:07:02,240
Oh, okay.

126
00:07:02,960 --> 00:07:05,520
First of all, that is a fracking cool shot.

127
00:07:07,200 --> 00:07:11,760
Second of all, I'm calculating by measuring the height of the hot water heater as it leaves

128
00:07:11,760 --> 00:07:15,680
frame in the high speed shot that it's leaving frame at about 350 miles an hour,

129
00:07:15,680 --> 00:07:19,760
which is pretty spot on to the speed I calculated the first time we did this.

130
00:07:19,760 --> 00:07:21,360
It hung in the air for 12 seconds.

131
00:07:21,360 --> 00:07:25,600
If I calculate the 12 seconds with air resistance plus the speed it's leaving the ground,

132
00:07:25,600 --> 00:07:29,600
I come up with a total height reached of about 560 feet,

133
00:07:29,600 --> 00:07:33,760
which is also close enough to our estimate last time to tell me that we were right.

134
00:07:33,760 --> 00:07:35,360
Well, that's without obstructions.

135
00:07:35,360 --> 00:07:36,000
That's correct.

136
00:07:36,000 --> 00:07:37,920
Well, let's put some obstructions in.

137
00:07:37,920 --> 00:07:38,720
Absolutely.

138
00:07:46,560 --> 00:07:51,200
All right, so what do we got?

139
00:07:51,200 --> 00:07:52,400
Remember curving a bullet?

140
00:07:52,400 --> 00:07:52,960
Totally.

141
00:07:52,960 --> 00:07:54,000
Totally busted.

142
00:07:54,000 --> 00:07:54,480
For sure.

143
00:07:54,480 --> 00:07:58,320
But there was another scene in the same movie where a bullet needs to get around an obstacle

144
00:07:58,320 --> 00:08:00,320
and the fans want us to check it out.

145
00:08:00,320 --> 00:08:01,600
Well, we missed one.

146
00:08:01,600 --> 00:08:02,320
Which one?

147
00:08:02,320 --> 00:08:04,400
Well, Angelina Jolie's character is in a shootout.

148
00:08:04,400 --> 00:08:08,240
She pulls out this amazing gun that literally shoots 90 degrees around a corner.

149
00:08:08,240 --> 00:08:10,560
So the fans want to find out if that even exists?

150
00:08:10,560 --> 00:08:11,200
Yep.

151
00:08:11,200 --> 00:08:11,440
All right.

152
00:08:11,440 --> 00:08:15,600
Well, while you do that, why don't Tori and I do two other Hollywood techniques?

153
00:08:15,920 --> 00:08:20,240
Yeah, action hero corner shots that you've seen in every action movie ever made.

154
00:08:20,240 --> 00:08:21,680
We'll see if they actually work.

155
00:08:21,680 --> 00:08:22,000
Cool.

156
00:08:23,520 --> 00:08:28,320
Our trio of gun toting gunslingers have already busted the bullet-bending antics

157
00:08:28,320 --> 00:08:30,480
as illustrated in the movie Wanted.

158
00:08:32,320 --> 00:08:34,720
There's no deviation whatsoever.

159
00:08:34,720 --> 00:08:39,920
But fantasy physics isn't the only method used in that film of shooting around an obstacle.

160
00:08:40,800 --> 00:08:43,040
There was also some fancy hardware.

161
00:08:43,040 --> 00:08:46,320
And to find out if this corner shot is fact or fiction,

162
00:08:47,600 --> 00:08:50,800
Carrie and an overly excited Grand and Tori

163
00:08:52,160 --> 00:08:57,280
have come to Alameda County Sheriff Department's live firehouse.

164
00:08:59,920 --> 00:09:02,800
It's like a playground, a very dangerous playground.

165
00:09:03,840 --> 00:09:07,280
But to make it more playground and less dangerous,

166
00:09:07,680 --> 00:09:12,160
Sergeant Rob McElroy has brought along some specially modified guns and ammo.

167
00:09:12,160 --> 00:09:16,160
What we've got is a special paint marking cartridge that we convert an actual firearm

168
00:09:16,160 --> 00:09:17,840
that it will only accept this round.

169
00:09:17,840 --> 00:09:22,160
And what it has is a small plastic capsule with a paint or dye inside of it

170
00:09:22,160 --> 00:09:24,960
that'll allow you to see where it hits and it will function the firearm.

171
00:09:26,960 --> 00:09:32,800
And first up, contract killer Carrie is going to show us if the corner shot is the real deal.

172
00:09:34,240 --> 00:09:35,760
Right to over the job.

173
00:09:35,840 --> 00:09:37,040
Right to over the job.

174
00:09:38,000 --> 00:09:43,200
And it's so far so good because the movie's machinery really does exist.

175
00:09:43,200 --> 00:09:47,440
Pop a handgun in the contraption and hey presto, you're good to go.

176
00:09:47,440 --> 00:09:48,560
Mama like.

177
00:09:48,560 --> 00:09:49,840
Yeah, what mama got.

178
00:09:50,800 --> 00:09:52,000
This is a corner shot.

179
00:09:52,000 --> 00:09:55,760
It's the real life version of what Angelina Jolie used in the movie.

180
00:09:55,760 --> 00:09:59,440
She pulled out this little compact cute weapon that shot around a corner.

181
00:09:59,440 --> 00:10:00,960
This is what you'd really use.

182
00:10:00,960 --> 00:10:03,760
And you could bend it around corners to take the shot.

183
00:10:03,760 --> 00:10:08,240
Yeah, it's got this little screen right here so you can see what you're shooting at with the crosshairs and bam.

184
00:10:08,240 --> 00:10:09,520
I love it.

185
00:10:09,520 --> 00:10:11,760
All right, show us what you got.

186
00:10:11,760 --> 00:10:12,720
Stand back.

187
00:10:12,720 --> 00:10:16,400
I think the boys were thoroughly impressed with my surprise piece of technology here.

188
00:10:16,400 --> 00:10:20,240
I mean, how amazing is it to be able to shoot around a corner

189
00:10:20,240 --> 00:10:22,720
without actually putting yourself in harm's way.

190
00:10:34,160 --> 00:10:37,520
So take note fans, that's score one for the movies.

191
00:10:37,520 --> 00:10:39,920
The corner shot is clearly the real deal.

192
00:10:40,800 --> 00:10:42,560
But the team ain't done yet.

193
00:10:42,560 --> 00:10:48,800
The guys want to try two other corner shot techniques any action movie fan will be familiar with.

194
00:10:48,800 --> 00:10:51,680
The question is, will they work in real life?

195
00:10:52,400 --> 00:10:59,360
My technique is to put only my arm around the corner, thus keeping my body out of the line of fire.

196
00:10:59,360 --> 00:11:00,320
Rob, clear the load.

197
00:11:00,320 --> 00:11:01,040
Clear the load.

198
00:11:02,000 --> 00:11:08,080
Got a specially modified pistol that shoots these gel markers so that we can see how well I do.

199
00:11:08,080 --> 00:11:09,200
You guys ready?

200
00:11:09,200 --> 00:11:09,520
Yeah.

201
00:11:14,000 --> 00:11:14,640
Where to hit?

202
00:11:14,640 --> 00:11:15,760
I didn't hit the target.

203
00:11:15,760 --> 00:11:16,720
You missed your target.

204
00:11:20,720 --> 00:11:24,320
And the target's still alive.

205
00:11:24,320 --> 00:11:28,480
Okay, so still intact, didn't hit the target at all.

206
00:11:28,560 --> 00:11:32,320
Blind firing around a corner is pretty much as you would expect.

207
00:11:32,320 --> 00:11:33,360
It's random.

208
00:11:33,360 --> 00:11:36,880
So, you know, if you can't see the target, how are you going to hit it?

209
00:11:38,000 --> 00:11:39,360
The clue is in the title.

210
00:11:40,320 --> 00:11:44,880
The one shot blind corner kill from the movies is clearly unrealistic.

211
00:11:46,160 --> 00:11:50,240
Now this next technique is definitely not taught by the Alameda County Sheriff's Department,

212
00:11:50,240 --> 00:11:52,640
but it is one that you see in tons of Hollywood movies.

213
00:11:52,640 --> 00:11:56,240
And that is flying into a room, surprising your target,

214
00:11:56,240 --> 00:11:58,320
and shooting your target as you're flying through the air.

215
00:12:00,960 --> 00:12:02,240
I think that'll work.

216
00:12:02,240 --> 00:12:04,880
All right, so there's action hero technique.

217
00:12:04,880 --> 00:12:06,000
Whenever you're ready.

218
00:12:06,000 --> 00:12:06,960
All right, here we go.

219
00:12:06,960 --> 00:12:09,920
Do you guys realize I've been practicing this technique since I was eight years old?

220
00:12:14,640 --> 00:12:16,240
That looks like you hit it.

221
00:12:16,240 --> 00:12:17,440
Yeah, got him.

222
00:12:18,080 --> 00:12:18,880
That is a kill.

223
00:12:19,520 --> 00:12:24,480
So that's one action movie move that does seem to work in real life.

224
00:12:25,520 --> 00:12:34,480
Not that you'll be seeing it in the Alameda County Sheriff's Training Manual anytime soon.

225
00:12:36,880 --> 00:12:38,640
Okay, so where does that leave us?

226
00:12:38,640 --> 00:12:41,120
Well, the hardware was not a figment of Hollywood's imagination.

227
00:12:41,120 --> 00:12:42,880
The corner shot is reality.

228
00:12:42,880 --> 00:12:44,000
Yeah, and I hit my target.

229
00:12:44,000 --> 00:12:46,160
I mean, dive me through a door with guns blazing.

230
00:12:46,160 --> 00:12:47,040
Seems to work.

231
00:12:47,040 --> 00:12:49,760
In a movie context, but without a mattress.

232
00:12:49,760 --> 00:12:51,600
And nobody shooting back at you.

233
00:12:51,600 --> 00:12:55,840
I mean, the chances of you getting away scot-free without any injury, pretty slim.

234
00:12:55,840 --> 00:12:57,280
Man, you guys are just jealous.

235
00:12:57,280 --> 00:12:58,000
All right, fine.

236
00:12:58,000 --> 00:12:58,640
Plausible.

237
00:12:58,640 --> 00:13:01,280
And as for your blind shot technique.

238
00:13:01,280 --> 00:13:03,440
Okay, that one is busted.

239
00:13:03,440 --> 00:13:06,960
Sticking your gun around the corner and blindly firing, you're not going to hit anything.

240
00:13:06,960 --> 00:13:07,520
Look at that.

241
00:13:07,520 --> 00:13:08,560
We got a full set.

242
00:13:08,560 --> 00:13:09,520
Yeah, confirmed.

243
00:13:09,520 --> 00:13:10,720
Plausible and busted.

244
00:13:10,720 --> 00:13:11,760
Is that a first?

245
00:13:11,760 --> 00:13:12,320
Probably not.

246
00:13:17,040 --> 00:13:20,720
Later, the myth of the snow plow split gets super sized.

247
00:13:20,720 --> 00:13:22,720
Two, one, fire.

248
00:13:24,080 --> 00:13:27,200
But next, car roof cling gets boxed in.

249
00:13:27,200 --> 00:13:27,760
Here we go.

250
00:13:36,240 --> 00:13:42,400
Before Adam and Jamie unnaturally select the story of the two-story water heater rocket,

251
00:13:42,400 --> 00:13:46,000
they're tackling a tall tail tangent from Tinseltown.

252
00:13:47,040 --> 00:13:48,960
Next is sort of a tangent.

253
00:13:48,960 --> 00:13:52,960
Do you remember the day that we spent hanging onto the roof and hanging onto the hood of a car

254
00:13:52,960 --> 00:13:54,720
while the other one kept trying to shake us off?

255
00:13:54,720 --> 00:13:55,040
Yeah.

256
00:13:55,040 --> 00:13:58,960
Well, fans say that we missed a crucial Hollywood element to that story.

257
00:13:59,520 --> 00:14:01,280
The cardboard box.

258
00:14:01,280 --> 00:14:06,080
You mean the cardboard boxes that inhabit every single Hollywood back alley?

259
00:14:06,080 --> 00:14:06,880
Absolutely.

260
00:14:06,880 --> 00:14:09,600
They said, if you're going to shake someone off a car in a Hollywood movie,

261
00:14:09,600 --> 00:14:11,680
you got to drive through a big stack of boxes.

262
00:14:12,480 --> 00:14:12,880
I'm there.

263
00:14:13,840 --> 00:14:18,160
In car roof cling, Adam and Jamie got a grip Hollywood style.

264
00:14:18,160 --> 00:14:19,040
Give me all you got.

265
00:14:20,000 --> 00:14:27,600
To see if you could really hold onto a moving car through zips, zags, and even sudden stops.

266
00:14:29,280 --> 00:14:31,840
I'm actually seeing some stars from that.

267
00:14:31,840 --> 00:14:33,760
But you weren't satisfied.

268
00:14:33,760 --> 00:14:38,480
Apparently, the guys missed out on the most obvious car cling cliche of all.

269
00:14:38,480 --> 00:14:43,920
Can you really hang in there when the baddie drives through an encumbrance of cardboard?

270
00:14:43,920 --> 00:14:48,400
Well, it looks like it's time to dust off the old car crane and set up some boxes,

271
00:14:48,400 --> 00:14:51,760
drive through them at, what, 45 miles an hour?

272
00:14:51,760 --> 00:14:52,320
Yeah.

273
00:14:52,320 --> 00:14:56,640
Tell you what, I'll set up the cardboard boxes and why don't you take the first trip through them

274
00:14:56,640 --> 00:14:58,240
just to make sure it's all safe?

275
00:14:59,120 --> 00:14:59,440
OK.

276
00:15:00,720 --> 00:15:04,720
So Jamie will be the car cling human Hoosier guinea pig.

277
00:15:04,720 --> 00:15:06,800
But first, the car needs some work.

278
00:15:06,800 --> 00:15:11,600
You may remember that the last thing that we did on the car cling episode was take it through a car wash.

279
00:15:12,160 --> 00:15:13,120
Oh, that's cool.

280
00:15:17,360 --> 00:15:18,480
Now we've got to put it back.

281
00:15:19,360 --> 00:15:21,920
Cue the Mythbusters editing cure-all.

282
00:15:21,920 --> 00:15:25,920
A timely time lapse with a slab dash of split screen.

283
00:15:25,920 --> 00:15:32,480
And with the rig ready to roll, it's back to the Alameda Naval Base, where Adam, for one, is excited.

284
00:15:32,480 --> 00:15:36,000
I'd like to set the scene for you if I might.

285
00:15:36,000 --> 00:15:40,720
I will be playing the driver as such I will be driving.

286
00:15:42,960 --> 00:15:51,680
And in some time in the past, I have insulted the mustachioed Hoosier played by Jamie.

287
00:15:55,360 --> 00:15:59,040
And he has come after me and I cannot shake him.

288
00:15:59,040 --> 00:16:03,760
It's six months and he's running after every train and flying after every plane.

289
00:16:03,760 --> 00:16:07,200
And now he's all my car and I can't shake him.

290
00:16:07,200 --> 00:16:13,040
Will the fan request of a box blockade really be enough to knock Jamie down and out?

291
00:16:13,040 --> 00:16:16,720
Sure enough, these boxes are filled with nothing but air, but just to make this one a little more interesting.

292
00:16:18,320 --> 00:16:20,640
I'm going to have Jamie do it with the windows up.

293
00:16:21,600 --> 00:16:25,120
But is the man of steel worried? Not one eye over.

294
00:16:25,120 --> 00:16:28,800
I don't even think I need to hold on when we're going through the boxes because

295
00:16:28,800 --> 00:16:33,920
other than get stuck on the big pink thing over my head, I don't see the problem here.

296
00:16:34,560 --> 00:16:40,640
With Jamie as nonchalant as ever, Adam secures the rig.

297
00:16:40,640 --> 00:16:41,440
All right, it's ready.

298
00:16:42,960 --> 00:16:46,880
Then Jamie clips in and checks that the crane can still take his weight,

299
00:16:48,080 --> 00:16:52,080
providing a visual treat that's too good for Adam to resist.

300
00:16:52,640 --> 00:16:55,520
You know how like vulcanized rubber was invented by accident?

301
00:16:55,600 --> 00:16:56,640
Wee.

302
00:16:56,640 --> 00:17:02,320
I think this may lead to a spate of Jamie Heineman pinatas all around the country.

303
00:17:02,320 --> 00:17:06,960
Once people see the moustache who's are floating around the front of the car in this test,

304
00:17:06,960 --> 00:17:09,280
they're going to want their own and they're going to want it for their birthday.

305
00:17:10,240 --> 00:17:14,080
But before any birthday celebrations, it's time to get myth busted.

306
00:17:15,920 --> 00:17:21,440
Slowly but surely, Adam accelerates up to a white knuckle 45 miles an hour.

307
00:17:21,440 --> 00:17:23,120
I'm going to get into character.

308
00:17:23,120 --> 00:17:24,480
Who's that? Oh my God.

309
00:17:25,680 --> 00:17:27,280
I couldn't shake them off.

310
00:17:27,280 --> 00:17:28,960
Oh, look, there's some boxes.

311
00:17:28,960 --> 00:17:32,880
I'll drive right through those and they'll get rid of them right away.

312
00:17:32,880 --> 00:17:33,360
Oh, no.

313
00:17:33,360 --> 00:17:34,000
There we go.

314
00:17:38,320 --> 00:17:42,800
Remarkably, Jamie sticks to the car like a gecko covered in glue.

315
00:17:42,800 --> 00:17:46,960
Even though he releases his grip to lessen the blow, he doesn't budge at all.

316
00:17:48,080 --> 00:17:50,640
We were moving pretty quick when we hit these boxes.

317
00:17:50,720 --> 00:17:53,680
It's just like the boxes in any Hollywood movie.

318
00:17:53,680 --> 00:17:56,640
These things are full of air, and so there's not that much to them.

319
00:17:56,640 --> 00:18:02,000
And any Hollywood stuntman, villain is going to be able to hang onto a car quite easily

320
00:18:02,000 --> 00:18:02,800
and go right through them.

321
00:18:03,440 --> 00:18:09,040
So it was plain sailing for Jamie, but will it be such a breeze for Adam on the hood?

322
00:18:09,040 --> 00:18:11,120
Well, it's my turn to be shaking off this car.

323
00:18:11,120 --> 00:18:17,040
I'm going to be trying it from the hood, and we have an added wrinkle that it's raining.

324
00:18:17,680 --> 00:18:18,560
But so what?

325
00:18:18,560 --> 00:18:20,880
Even if that makes it harder, rain happens in the real world.

326
00:18:20,880 --> 00:18:21,680
We can work with it.

327
00:18:22,240 --> 00:18:24,960
But rain is not the only wrinkle Adam's facing.

328
00:18:24,960 --> 00:18:25,680
That won't.

329
00:18:25,680 --> 00:18:27,760
Now it's time for Jamie to get a little payback.

330
00:18:27,760 --> 00:18:32,800
He's using both a lot more boxes than I did, and he stacked them in the way to provide the

331
00:18:32,800 --> 00:18:35,760
maximum amount of resistance to me for holding on.

332
00:18:36,880 --> 00:18:38,560
I still think I'm going to be able to hold on though.

333
00:18:41,040 --> 00:18:44,640
Adam and he'll be able to hold on just like in the movies.

334
00:18:44,720 --> 00:18:47,600
Jamie floors it while Adam freaks out.

335
00:18:47,600 --> 00:18:48,160
Here we go.

336
00:18:57,840 --> 00:19:00,000
Yeah, I stayed on.

337
00:19:00,000 --> 00:19:00,800
They nail it.

338
00:19:01,760 --> 00:19:07,120
At 45 miles an hour, Adam's grip held, and you could say he's rather pleased.

339
00:19:09,360 --> 00:19:12,240
I'd say if that tests, it's boxes zero.

340
00:19:13,040 --> 00:19:14,880
Adam as a super villain won.

341
00:19:15,760 --> 00:19:18,720
But on closer inspection, Jamie's not so sure.

342
00:19:19,600 --> 00:19:21,920
In the box test, Adam didn't get thrown off the car.

343
00:19:21,920 --> 00:19:23,360
He didn't get hurt or anything.

344
00:19:23,360 --> 00:19:27,120
But when we went back and looked at the footage, we saw something really interesting,

345
00:19:27,120 --> 00:19:31,040
and that was that for a second, Adam lost his grip on the hood,

346
00:19:31,040 --> 00:19:33,440
and he actually got plastered against the windshield.

347
00:19:36,240 --> 00:19:38,400
It was a blink and you'll miss it moment.

348
00:19:39,360 --> 00:19:41,680
But Adam did momentarily let go.

349
00:19:43,120 --> 00:19:45,520
But he got his grip back before he slid off.

350
00:19:46,240 --> 00:19:46,640
Yeah.

351
00:19:47,600 --> 00:19:49,040
So how do you want to call this one?

352
00:19:49,040 --> 00:19:53,120
Well, I'd say the myth that you can hang on while driving through a pile of boxes is

353
00:19:53,680 --> 00:19:54,800
pretty well confirmed.

354
00:19:54,800 --> 00:19:58,960
I mean, it was a little disconcerting hitting all those boxes at high speed,

355
00:19:58,960 --> 00:20:02,160
but I wasn't in any danger of getting pushed off.

356
00:20:02,160 --> 00:20:06,320
Now, this is helped by the fact that all the boxes you drive through in Hollywood seem to be empty.

357
00:20:06,320 --> 00:20:09,680
I think if you were driving through a shipment of VCRs or anvils,

358
00:20:09,680 --> 00:20:11,200
it would be a totally different story.

359
00:20:12,160 --> 00:20:13,520
Yeah, especially anvils.

360
00:20:13,520 --> 00:20:14,960
Yeah, but it's confirmed for now.

361
00:20:18,400 --> 00:20:22,160
Still to come, the Water Heater Story goes two-story.

362
00:20:22,160 --> 00:20:23,440
I love the hot water heaters.

363
00:20:23,440 --> 00:20:24,880
They're my favorite explosions.

364
00:20:24,880 --> 00:20:29,200
But coming up, the guys go lock picking with liquid nitrogen.

365
00:20:29,200 --> 00:20:31,440
Dic doc, buddy. Cops are on their way.

366
00:20:34,800 --> 00:20:40,880
Next up for an evolution revolution is one of the coolest stories the team has ever tackled.

367
00:20:41,440 --> 00:20:44,720
Okay, so our next myth evolution comes from one of our recent episodes,

368
00:20:44,720 --> 00:20:45,520
liquid nitrogen.

369
00:20:45,520 --> 00:20:46,720
All right, so where's this one going?

370
00:20:46,720 --> 00:20:49,040
Well, the fans want us to test another LN2 myth,

371
00:20:49,040 --> 00:20:51,600
this time that it can be used as a lock pick.

372
00:20:51,600 --> 00:20:54,320
Yeah, I've seen that on TV, like MacGyver or Burn Notice.

373
00:20:54,320 --> 00:20:56,480
They spray liquid nitrogen into a lock,

374
00:20:56,480 --> 00:20:58,800
and then they can shatter it with a gun butt or a hammer.

375
00:20:58,800 --> 00:20:59,760
Well, this sounds pretty simple.

376
00:20:59,760 --> 00:21:01,280
The test will just set up some locks,

377
00:21:01,280 --> 00:21:03,440
we'll try to break in with the regular burglar kit,

378
00:21:03,440 --> 00:21:06,640
and then we'll try to break in using liquid nitrogen and we'll see which one's faster.

379
00:21:06,640 --> 00:21:08,480
What is a regular burglar kit?

380
00:21:08,480 --> 00:21:10,800
You know, like crowbars, hammers, stuff like that.

381
00:21:10,800 --> 00:21:12,240
You guys don't have a burglar kit?

382
00:21:12,240 --> 00:21:13,040
No.

383
00:21:13,040 --> 00:21:13,280
No.

384
00:21:15,840 --> 00:21:18,320
The last time it tackled liquid nitrogen,

385
00:21:18,320 --> 00:21:20,800
the fables the team faced were frightening.

386
00:21:24,160 --> 00:21:25,760
They look just like the movie.

387
00:21:26,480 --> 00:21:27,360
And festive.

388
00:21:29,920 --> 00:21:32,400
But now they want to pick a lock or two,

389
00:21:32,400 --> 00:21:36,800
and to find out if freezing your locks off is really fact or fiction,

390
00:21:36,800 --> 00:21:38,480
Tori is starting with the control.

391
00:21:39,040 --> 00:21:44,320
A simple padlock at room temperature versus a hammer and crowbar combination.

392
00:21:44,720 --> 00:21:46,640
Okay, control padlock.

393
00:21:46,640 --> 00:21:48,160
Three, two, one.

394
00:21:52,880 --> 00:21:53,920
Four seconds.

395
00:21:53,920 --> 00:21:55,600
That's the reference point.

396
00:21:55,600 --> 00:22:00,240
Now to find out what difference soaking the lock in liquid nitrogen will make.

397
00:22:00,240 --> 00:22:02,880
So we're on to test two, which is the liquid nitrogen part of this test.

398
00:22:02,880 --> 00:22:05,280
We're going to pour liquid nitrogen directly on the lock

399
00:22:05,280 --> 00:22:07,600
and let it soak for a few minutes so it gets good and frozen,

400
00:22:07,600 --> 00:22:10,320
and then Tori's going to give it the same bash that he gave the control lock.

401
00:22:11,200 --> 00:22:12,160
Okay, hose is off.

402
00:22:12,720 --> 00:22:16,480
Personally, I'm hoping for some sort of cartoon-like shatter here.

403
00:22:16,480 --> 00:22:18,480
In three, two, one.

404
00:22:22,480 --> 00:22:22,960
Okay.

405
00:22:22,960 --> 00:22:23,920
We're looking at that.

406
00:22:23,920 --> 00:22:25,360
We'll get one second.

407
00:22:25,360 --> 00:22:28,240
I see we made a difference with the liquid nitrogen.

408
00:22:28,240 --> 00:22:29,280
That is cool.

409
00:22:31,280 --> 00:22:32,880
So it's looking good for the myth.

410
00:22:33,600 --> 00:22:38,320
But considering the padlock was so easy to break, even without the LM2,

411
00:22:38,320 --> 00:22:40,160
the team wants a tougher challenge.

412
00:22:41,040 --> 00:22:43,440
All right, if anybody needs me, I'll be in my office.

413
00:22:43,440 --> 00:22:45,520
For that, they want a deadbolt.

414
00:22:45,520 --> 00:22:50,480
And as before, Tori is first going to smash through for a control comparison.

415
00:22:51,280 --> 00:22:53,040
This always reminds me of elementary school.

416
00:22:54,320 --> 00:22:55,200
School of hard knocks.

417
00:22:56,320 --> 00:22:58,720
So I broke through the deadbolt using the pick and the sledgehammer.

418
00:22:58,720 --> 00:23:00,960
Tick tock, buddy. Cops are on their way.

419
00:23:01,920 --> 00:23:03,520
But it took me five and a half minutes.

420
00:23:03,520 --> 00:23:05,520
It was very hard. It was very loud.

421
00:23:06,160 --> 00:23:07,200
There you go.

422
00:23:07,200 --> 00:23:08,720
Pretty sure somebody would have called the cops.

423
00:23:08,720 --> 00:23:09,360
Go, go, go.

424
00:23:09,920 --> 00:23:10,800
Okay.

425
00:23:10,800 --> 00:23:13,120
Five minutes and 37 seconds.

426
00:23:13,120 --> 00:23:17,360
Five minutes and 37 seconds for the control.

427
00:23:17,360 --> 00:23:20,880
Now let's soak it in liquid nitrogen and see if it blasts through that lock faster.

428
00:23:20,880 --> 00:23:25,280
With a full four minutes exposure to liquid nitrogen's mind boggling

429
00:23:25,360 --> 00:23:31,280
minus 321 degrees Fahrenheit, the lock is ready for our not so subtle burglar.

430
00:23:31,280 --> 00:23:32,720
In three, two, one.

431
00:23:35,280 --> 00:23:36,240
Oh my gosh.

432
00:23:38,240 --> 00:23:39,760
That's incredible.

433
00:23:39,760 --> 00:23:41,760
One shot in the lock already broke.

434
00:23:41,760 --> 00:23:42,880
Keep going, keep going.

435
00:23:42,880 --> 00:23:46,080
Oh my God. That's hilarious.

436
00:23:46,080 --> 00:23:49,440
Why is liquid nitrogen making it easier to break these locks?

437
00:23:49,440 --> 00:23:51,280
Well, all metal has a dectility to it,

438
00:23:51,280 --> 00:23:55,600
which means if I smash this lock with a hammer, it's going to deform the metal.

439
00:23:55,600 --> 00:23:58,800
Whereas if I introduce the liquid nitrogen to the lock,

440
00:23:58,800 --> 00:24:03,360
we are going to lower the temperature, causing all the particles that are in constant motion

441
00:24:03,360 --> 00:24:06,640
to slow down, removing energy, making it brittle,

442
00:24:06,640 --> 00:24:10,080
so that if I now smash it with a hammer, it's actually going to shatter.

443
00:24:12,640 --> 00:24:14,720
Nice. That is incredible.

444
00:24:14,720 --> 00:24:15,440
What's the time?

445
00:24:15,440 --> 00:24:16,400
One minute, four seconds.

446
00:24:16,400 --> 00:24:18,880
That is way less than half your time.

447
00:24:18,880 --> 00:24:21,120
One shot and the lock shattered.

448
00:24:21,680 --> 00:24:23,280
This myth is totally confirmed.

449
00:24:23,280 --> 00:24:27,280
I know, and I just can't believe how big of a difference it made using the liquid nitrogen.

450
00:24:27,280 --> 00:24:31,520
Wait, did we just give our audience a guide to making breaking and entering easier?

451
00:24:31,520 --> 00:24:32,480
Yeah, pretty cool, huh?

452
00:24:32,480 --> 00:24:36,480
Yeah, okay. That did occur to me, but this is a difficult technique to use.

453
00:24:36,480 --> 00:24:40,400
One, you need to carry around a thermally isolated vat of liquid nitrogen.

454
00:24:40,400 --> 00:24:42,800
Two, you need a large amount of safety equipment.

455
00:24:42,800 --> 00:24:45,920
Three, you need to apply it to the lock for at least five minutes.

456
00:24:45,920 --> 00:24:48,800
And four, you need three people to pull it off.

457
00:24:48,880 --> 00:24:51,600
Yes, it's successful, but you know what?

458
00:24:51,600 --> 00:24:53,680
It's not the most subtle technique out there.

459
00:24:53,680 --> 00:24:55,520
Yeah, I agree. It's probably not going to catch on.

460
00:24:55,520 --> 00:24:58,320
You know what, though? This myth is still confirmed.

461
00:24:58,320 --> 00:24:58,960
Confirmed.

462
00:25:15,200 --> 00:25:18,320
I'm calculating a total height reached of about 560 feet.

463
00:25:19,120 --> 00:25:19,680
Okay, good.

464
00:25:20,400 --> 00:25:22,640
Now in part two, you want to know,

465
00:25:23,360 --> 00:25:26,480
will the tech break through the roof of a two-story house?

466
00:25:27,200 --> 00:25:28,960
We're going to start putting down floors.

467
00:25:28,960 --> 00:25:29,760
One in the basement.

468
00:25:29,760 --> 00:25:30,880
Good, good, good.

469
00:25:30,880 --> 00:25:34,000
One here on the first floor, put up a ceiling and a roof,

470
00:25:34,000 --> 00:25:35,840
and then it's time to plum up a hot water heater.

471
00:25:39,360 --> 00:25:40,240
That's that.

472
00:25:40,240 --> 00:25:44,560
And with the major construction complete, now begins the delicate task

473
00:25:46,240 --> 00:25:48,160
of hoisting the pieces into place.

474
00:25:49,600 --> 00:25:51,920
Well, the moment we sent a hot water heater up through the roof

475
00:25:51,920 --> 00:25:54,800
of our little red shack, fans rode to us and said,

476
00:25:54,800 --> 00:25:57,040
yeah, but dude, that's like a bungalow.

477
00:25:57,040 --> 00:25:59,200
In my house, the hot water heater's in the basement.

478
00:25:59,200 --> 00:26:01,840
You got to do it again because it's got to have more obstacles

479
00:26:01,840 --> 00:26:02,880
to be realistic.

480
00:26:02,880 --> 00:26:05,200
And we actually spent a lot of time and energy

481
00:26:05,200 --> 00:26:07,440
looking for two-story houses to destroy.

482
00:26:08,000 --> 00:26:10,160
And then we realized we could just build one.

483
00:26:12,480 --> 00:26:13,920
In fact, not only could we just build one,

484
00:26:13,920 --> 00:26:16,240
we can build one without sides so that we can see

485
00:26:16,240 --> 00:26:18,560
exactly what was happening because it's not about the walls.

486
00:26:18,640 --> 00:26:19,520
It's about the floors.

487
00:26:19,520 --> 00:26:21,680
It's about the obstacles in the way of the hot water heater.

488
00:26:21,680 --> 00:26:25,280
So we came up with this system, bolting together upright,

489
00:26:25,280 --> 00:26:29,520
four-by-four inch pieces of steel, two holding together a steel frame

490
00:26:29,520 --> 00:26:31,840
on which we could place each of our three floors,

491
00:26:31,840 --> 00:26:34,480
basement, first floor, ceiling, and roof.

492
00:26:34,480 --> 00:26:37,920
All the obstacles we need to place in the way of our hot water heater.

493
00:26:37,920 --> 00:26:38,480
That's perfect.

494
00:26:39,600 --> 00:26:41,120
I'm about to dress the top floor.

495
00:26:41,680 --> 00:26:44,400
This right here is my interior decorating tool.

496
00:26:44,400 --> 00:26:46,400
Ha ha ha.

497
00:26:47,920 --> 00:26:48,880
There you go, Buster.

498
00:26:48,880 --> 00:26:50,080
All the comforts of home.

499
00:26:50,640 --> 00:26:53,120
Jamie is plumbing the hot water heater down below.

500
00:26:53,120 --> 00:26:54,240
And there we go.

501
00:26:54,240 --> 00:26:57,200
Soon we're going to find out if this thing can actually go through

502
00:26:57,200 --> 00:26:58,240
all of our model house.

503
00:27:01,600 --> 00:27:02,080
Boom!

504
00:27:02,960 --> 00:27:05,920
Coming right up, take one snowplow wedge,

505
00:27:05,920 --> 00:27:09,760
add 12 rockets, and mix well with one car.

506
00:27:09,760 --> 00:27:10,720
We're ready to launch.

507
00:27:14,480 --> 00:27:18,640
Next up, it's time for Carrie, Tori, and Grant to split.

508
00:27:19,600 --> 00:27:21,520
Okay, so what's evolving for us?

509
00:27:21,520 --> 00:27:24,000
Snowplow split from the Alaska Special.

510
00:27:24,000 --> 00:27:27,760
Okay, that's the story where a car hits a snowplow, splits clean in half,

511
00:27:27,760 --> 00:27:29,440
a perfect bifurcation.

512
00:27:29,440 --> 00:27:30,560
Yeah, we busted that one.

513
00:27:30,560 --> 00:27:34,240
The rear engine car got a great split, but still didn't make it all the way through.

514
00:27:34,240 --> 00:27:34,960
Yeah, you're right.

515
00:27:34,960 --> 00:27:36,640
However, the fans want more.

516
00:27:36,640 --> 00:27:39,120
They've been sending us hundreds of emails saying,

517
00:27:39,120 --> 00:27:40,400
yes, the testing was good.

518
00:27:40,400 --> 00:27:41,840
Yes, the results were accurate.

519
00:27:41,840 --> 00:27:44,720
However, we did not replicate the results of the myth.

520
00:27:44,720 --> 00:27:49,760
So the fans basically want some sort of monster crash scenario that cuts a car in half.

521
00:27:49,760 --> 00:27:50,960
Sounds spectacular.

522
00:27:50,960 --> 00:27:52,880
Kind of hard, but spectacular.

523
00:27:52,880 --> 00:27:56,400
It was an Alaskan anecdote that was snow-joe.

524
00:27:56,400 --> 00:28:01,600
A car allegedly plowed into a plow and was split completely in two.

525
00:28:01,600 --> 00:28:03,920
But then again, maybe not.

526
00:28:03,920 --> 00:28:07,200
Because back in the real world, two incomplete splits

527
00:28:07,200 --> 00:28:09,280
That is not busted!

528
00:28:09,280 --> 00:28:11,520
meant the myth was well and truly busted.

529
00:28:12,800 --> 00:28:14,800
But that wasn't good enough for you.

530
00:28:15,680 --> 00:28:21,280
Because you've asked us to find out if under any super-sized circumstances

531
00:28:21,280 --> 00:28:24,000
a car could ever be split in twain.

532
00:28:24,720 --> 00:28:27,680
So in that last test, we got the car going 70 miles an hour.

533
00:28:27,680 --> 00:28:31,120
It smashed into that snow plow, split through the front end of the vehicle,

534
00:28:31,120 --> 00:28:33,440
the front axle, and the dashboard.

535
00:28:33,440 --> 00:28:37,360
It stopped before it even got through the toughest part of the car, the engine block.

536
00:28:37,360 --> 00:28:41,520
Yeah, to get through that, we need impact forces 10 times that amount.

537
00:28:41,520 --> 00:28:44,880
Which would mean our car would be going close to the speed of sound.

538
00:28:44,880 --> 00:28:48,240
Now to most people that might sound very difficult, but we're myth busters

539
00:28:48,240 --> 00:28:50,080
and I think I know just the place.

540
00:28:50,080 --> 00:28:50,960
Where?

541
00:28:50,960 --> 00:28:54,880
So where do you go when you need to make a rocket-powered superplow?

542
00:28:54,880 --> 00:28:56,720
Well, New Mexico Tech.

543
00:28:56,720 --> 00:29:02,560
They actually have a rocket sled here that can propel materials in an excess of 500 miles an hour.

544
00:29:02,560 --> 00:29:06,880
Now just to put that into perspective for you, that is faster than a jet airplane.

545
00:29:07,600 --> 00:29:12,560
Last time the team used this straight-track rocket roller coaster,

546
00:29:12,560 --> 00:29:15,040
they more than pancaked a car.

547
00:29:15,040 --> 00:29:18,160
And in a world first, Adam was speechless.

548
00:29:20,880 --> 00:29:25,600
This time the man with the launch codes is our old friend Dr. Van Romero.

549
00:29:25,600 --> 00:29:28,720
So this is the rocket sled for our superplow?

550
00:29:28,720 --> 00:29:32,720
Right, this is kind of the generic sled that we use to run down the track.

551
00:29:32,720 --> 00:29:34,800
We load rocket engines in here.

552
00:29:34,800 --> 00:29:38,080
Brust comes out the back and the business end of the sled is on the front.

553
00:29:40,560 --> 00:29:45,600
And jolking of the business end, it's time to beef up the plow part of the equation.

554
00:29:45,600 --> 00:29:48,320
Because this time they're switching things around.

555
00:29:48,320 --> 00:29:51,040
You can't just go to the store and buy an off-the-shelf plow.

556
00:29:51,040 --> 00:29:53,920
I mean it would explode, it would disintegrate.

557
00:29:53,920 --> 00:29:58,880
So we've got to make our own plow from scratch using this giant pile of steel.

558
00:29:58,880 --> 00:30:02,560
We're going to weld it into a plow shape, attach it to the rocket sled,

559
00:30:02,560 --> 00:30:04,800
and send it down the track at the car.

560
00:30:08,720 --> 00:30:12,960
Yep, unlike the previous experiment where the car was towed into the plow,

561
00:30:14,000 --> 00:30:17,360
this time the plow will be thrust into the car.

562
00:30:17,360 --> 00:30:19,120
But first, they've got to make it.

563
00:30:19,920 --> 00:30:21,440
Well this shouldn't take too long.

564
00:30:21,440 --> 00:30:24,000
Now we'll be done by lunchtime tomorrow.

565
00:30:24,720 --> 00:30:26,080
We're thinking about making this wedge.

566
00:30:26,080 --> 00:30:28,240
We're thinking it had to be as thin as possible.

567
00:30:28,240 --> 00:30:30,800
And it had to be basically a solid piece of steel.

568
00:30:30,800 --> 00:30:33,600
Now to get a solid piece of steel that big would be too hard.

569
00:30:33,600 --> 00:30:39,520
So what we did is we've taken many layers of steel, stacked them together to make that wedge shape.

570
00:30:39,520 --> 00:30:40,720
And then we've welded it together.

571
00:30:40,720 --> 00:30:42,880
Now we're grinding it so that it has a sharp point.

572
00:30:44,080 --> 00:30:48,480
While Grant and Tori have been prepping the replicate the result super plow,

573
00:30:48,480 --> 00:30:51,520
Carrie has been pimping the soon-to-be-pulped car.

574
00:30:52,560 --> 00:30:53,120
Alaska!

575
00:30:54,400 --> 00:30:56,160
You ready to see our super plow?

576
00:30:56,160 --> 00:30:57,520
Yeah, how is it?

577
00:30:57,520 --> 00:30:58,880
Oh, it looks good.

578
00:30:58,880 --> 00:31:00,240
I think the car's going to lose.

579
00:31:00,960 --> 00:31:05,760
Yep, but will it be cleanly bifurcated as per the fans' demands?

580
00:31:05,760 --> 00:31:08,800
The only way to find out is to get it off the truck.

581
00:31:09,600 --> 00:31:10,880
Okay, here we go.

582
00:31:10,880 --> 00:31:11,840
And onto the track.

583
00:31:14,560 --> 00:31:19,760
And with a plow in place, all the Mythbusters need to do now is come back tomorrow

584
00:31:19,760 --> 00:31:21,600
and strap on those rockets.

585
00:31:22,400 --> 00:31:24,720
That looked like about 500 miles an hour to me.

586
00:31:24,720 --> 00:31:25,360
At least.

587
00:31:26,160 --> 00:31:30,000
Next up, will the water heater rocket ram its way through the roof?

588
00:31:30,000 --> 00:31:31,200
It'll happen anytime now.

589
00:31:38,160 --> 00:31:40,800
This is either a hot water heater or it's a bomb.

590
00:31:40,800 --> 00:31:42,400
If it's a hot water heater, there's no problem.

591
00:31:42,400 --> 00:31:44,240
It just heats the water in your house.

592
00:31:44,240 --> 00:31:49,760
If it's a bomb, it fails catastrophically, sending the bottom shooting out,

593
00:31:49,760 --> 00:31:51,920
sending the top shooting up.

594
00:31:51,920 --> 00:31:55,440
This floor isn't going to offer much resistance to that water heater.

595
00:31:55,520 --> 00:32:00,000
The question we want to know is, what's it going to do when it hits this roof?

596
00:32:00,560 --> 00:32:04,880
Is it going to make a nice clean, round hole I can stare all the way into the basement through?

597
00:32:04,880 --> 00:32:09,360
Or is it going to be interrupted on its journey into the sky and never make it out of the house?

598
00:32:09,360 --> 00:32:10,960
That's what we want to find out.

599
00:32:10,960 --> 00:32:13,360
We're wired, we're plumbed, we're ready to go.

600
00:32:13,360 --> 00:32:16,240
All I need to do is fire the jennies up and wait.

601
00:32:16,880 --> 00:32:21,040
And with that generator up and running, the heating element inside the tank

602
00:32:21,040 --> 00:32:23,040
begins to slowly warm the water.

603
00:32:23,280 --> 00:32:28,640
Deep in Buster's basement, changes are occurring in his water heater.

604
00:32:28,640 --> 00:32:31,440
Changes that could affect his life.

605
00:32:31,440 --> 00:32:32,560
Oh look, we've turned red.

606
00:32:32,560 --> 00:32:34,640
175 psi.

607
00:32:34,640 --> 00:32:37,760
Ah, this fence is killing me.

608
00:32:37,760 --> 00:32:40,880
I think it's going to make it quite a ways through the building.

609
00:32:40,880 --> 00:32:43,040
It might just make it out the top.

610
00:32:43,040 --> 00:32:44,480
Beyond that, I don't know.

611
00:32:45,360 --> 00:32:47,440
Wow, an actual prediction.

612
00:32:47,440 --> 00:32:48,080
That's awesome.

613
00:32:48,080 --> 00:32:50,800
Now it's really starting to accelerate.

614
00:32:50,800 --> 00:32:52,400
All that potential is waiting.

615
00:32:53,040 --> 00:32:56,640
It's really nice seeing it exposed like that, our visible house.

616
00:32:56,640 --> 00:33:00,800
It's really extraordinary to see the whole thing clear as day.

617
00:33:00,800 --> 00:33:01,200
I know.

618
00:33:01,200 --> 00:33:02,320
It's really elegant, isn't it?

619
00:33:02,320 --> 00:33:02,820
Yeah.

620
00:33:06,000 --> 00:33:11,040
What's interesting to me here is that this is just a transfer of energy for E25.

621
00:33:11,040 --> 00:33:13,040
Oh, god, it's any second now.

622
00:33:13,040 --> 00:33:14,880
I don't want to turn back and look at the pressure anymore.

623
00:33:15,680 --> 00:33:17,680
I don't want to take my eyes off of it.

624
00:33:17,680 --> 00:33:21,200
Starting with the diesel fuel that's powering the generator,

625
00:33:21,200 --> 00:33:26,400
it's creating electricity that allows us to heat up this water in a container that releases all that

626
00:33:26,400 --> 00:33:27,840
energy all at once.

627
00:33:27,840 --> 00:33:31,920
It's really kind of interesting in a zen sort of way when you think about it.

628
00:33:31,920 --> 00:33:32,720
330.

629
00:33:37,520 --> 00:33:39,440
Okay, I'm going to do some live math here.

630
00:33:39,440 --> 00:33:42,000
The hot water heater itself is 18 inches in diameter.

631
00:33:42,000 --> 00:33:47,200
Now for the area of that, it's pi r squared, which equals 254 square inches of the bottom.

632
00:33:47,200 --> 00:33:50,480
Now you've got a pounds per square inch pressure inside of 336.

633
00:33:50,480 --> 00:33:51,360
Multiply that.

634
00:33:51,360 --> 00:33:56,720
By 254, you get 85,500 pounds of pressure.

635
00:33:56,720 --> 00:33:57,600
Let me say that again.

636
00:33:57,600 --> 00:34:02,560
85,500 pounds of pressure pushing against the bottom of the heater.

637
00:34:03,280 --> 00:34:04,640
You would fail too.

638
00:34:04,640 --> 00:34:05,600
335.

639
00:34:17,760 --> 00:34:18,560
You know what I see?

640
00:34:19,520 --> 00:34:21,440
I see a hole in the roof, man.

641
00:34:22,240 --> 00:34:23,520
Holy cow.

642
00:34:23,520 --> 00:34:26,560
Now that's what I call mission accomplished.

643
00:34:26,560 --> 00:34:30,240
I wish you could be here for this kind of explosion because when the hot water is finally

644
00:34:30,240 --> 00:34:35,920
bluest, you're staring right at it because we know where the zone is and the thud that comes out of it is so

645
00:34:36,640 --> 00:34:40,160
deeply guttural and still one kind of thud.

646
00:34:41,920 --> 00:34:42,720
It's great.

647
00:34:42,720 --> 00:34:43,360
Watch it again.

648
00:34:48,560 --> 00:34:53,520
Give me some skin there.

649
00:34:53,520 --> 00:35:01,520
Looking at the damage the water heater did to the building, it left some neat holes in the first floor

650
00:35:01,520 --> 00:35:09,520
and through the roof, which is no big deal, but looking more carefully, you realize what a shock the entire building took.

651
00:35:09,520 --> 00:35:10,320
Wow.

652
00:35:10,320 --> 00:35:13,360
Yeah, look at how much damage it did to the plywood right here.

653
00:35:13,440 --> 00:35:20,720
The cinder blocks that I put underneath the ground floor are actually shattered from the downward push.

654
00:35:20,720 --> 00:35:26,480
It actually lifted the entire roof off of its seat and then set it down.

655
00:35:27,360 --> 00:35:30,160
You know, this would pretty much ruin your house.

656
00:35:36,160 --> 00:35:36,880
Look at that, man.

657
00:35:36,880 --> 00:35:41,360
It tipped the TV table over, but Buster's still in the couch.

658
00:35:41,360 --> 00:35:43,360
What does all this carnage mean for our man?

659
00:35:43,360 --> 00:35:44,560
I'm glad you asked.

660
00:35:44,560 --> 00:35:47,360
I think it handily plausibleizes it.

661
00:35:47,360 --> 00:36:01,360
I think absolutely if you manage to idiotically cap off all the safety systems on the hot water heater in the basement of your house, it's going to go up through the floor, up through the ceiling, up through the roof and leave a hole in its wake.

662
00:36:01,360 --> 00:36:03,360
Let's check out the water heater.

663
00:36:03,360 --> 00:36:04,160
All right.

664
00:36:04,160 --> 00:36:06,160
Well, there's your problem.

665
00:36:06,160 --> 00:36:10,160
Well, the water heater did its job pretty much on target.

666
00:36:10,960 --> 00:36:12,960
It went through the building just.

667
00:36:12,960 --> 00:36:14,960
It spun around up here and then banged.

668
00:36:14,960 --> 00:36:16,960
We caught it back on our scaffolding.

669
00:36:18,960 --> 00:36:20,960
That's pretty hot.

670
00:36:20,960 --> 00:36:22,960
That's a good day.

671
00:36:22,960 --> 00:36:24,960
Yep, it has been a good day.

672
00:36:24,960 --> 00:36:26,960
A satisfying explosion or two.

673
00:36:26,960 --> 00:36:30,960
A new water heater rocket world record at 560 feet.

674
00:36:31,760 --> 00:36:41,760
Plus a plausible conclusion to the myth that a water heater can blast through the roof of your two-story home, albeit only just.

675
00:36:41,760 --> 00:36:45,760
Well, that's not bad day's work and a plausible myth to boot.

676
00:36:45,760 --> 00:36:51,760
Yeah, your hot water heater could just be a ticking time bomb in your basement.

677
00:36:51,760 --> 00:36:53,760
Ha ha ha.

678
00:37:01,760 --> 00:37:03,760
That was one of the coolest things I've ever seen.

679
00:37:09,760 --> 00:37:13,760
Our intrepid trio are evolving the third installment in the snow plow trilogy.

680
00:37:13,760 --> 00:37:15,760
Oh, crap. Somebody graffiti it all over our sled.

681
00:37:15,760 --> 00:37:23,760
And the means that the mythbusters are going to use is a cool 75,000 pounds of rocket thrust.

682
00:37:23,760 --> 00:37:27,760
But what's not so cool is the art Carrie has brought to the plow project.

683
00:37:28,560 --> 00:37:32,560
I added some finishing touches so that it'll look better on high speed. Now it's bright.

684
00:37:32,560 --> 00:37:34,560
Oh, you did this?

685
00:37:34,560 --> 00:37:36,560
Yeah. Isn't it pretty?

686
00:37:36,560 --> 00:37:38,560
Perfect.

687
00:37:38,560 --> 00:37:40,560
Good job.

688
00:37:42,560 --> 00:37:46,560
So this is it. The final experiment for snow plow and this is how it's going to go down.

689
00:37:46,560 --> 00:37:48,560
This is our superplow that we're going to load up with 12 rockets.

690
00:37:48,560 --> 00:37:54,560
It's going to propel this sled 750 feet down the track going 500 miles an hour.

691
00:37:57,760 --> 00:38:06,560
But we actually need the sled to travel 770 feet because for the last 20 feet it's going to come off the track and fly through the air.

692
00:38:06,560 --> 00:38:14,560
It hit our target. This car, if all goes according to plan, only the wedge part of the superplow should cut right through the car and the rocket sled should slide right underneath.

693
00:38:16,560 --> 00:38:20,560
So the sled we're going to use for our experiment. How many rockets are going to be on that?

694
00:38:20,560 --> 00:38:25,760
We're going to use 12 of these five inch HVARS. Each one has about 6,500 pounds of thrust.

695
00:38:25,760 --> 00:38:29,760
So total we should get about 75,000 pounds of thrust on that one sled.

696
00:38:29,760 --> 00:38:33,760
So do you have any extras of these laying around?

697
00:38:33,760 --> 00:38:35,760
Yeah, don't touch that.

698
00:38:35,760 --> 00:38:43,760
And while the New Mexico Tech Techs lock and load their rockets, the mythbusters are predicting the end of the road for the car.

699
00:38:43,760 --> 00:38:49,760
So far we have not been able to split a car all the way in half with the snow plow. We used a front engine vehicle. That didn't work.

700
00:38:49,760 --> 00:38:51,760
We used a rear engine vehicle. That didn't work.

701
00:38:51,760 --> 00:38:59,760
But now we have a rocket powered superplow. This thing is going to be going 500 miles an hour. I don't think it really matters where the engine is on this vehicle.

702
00:38:59,760 --> 00:39:07,760
Is it going to split it right in half? I don't think so. I have a feeling once it hits that engine, wherever the engine is, it's just going to shred that car into a bunch of little pieces.

703
00:39:07,760 --> 00:39:16,760
Now I know what this rocket sled can do. And I've seen what a snow plow with a really sharp pointy tip can do to a car at 70 miles an hour.

704
00:39:16,760 --> 00:39:22,760
Now when this rocket sled is going 500 miles an hour into this car, I think it doesn't have a chance.

705
00:39:22,760 --> 00:39:28,760
It's not only going to split into two, but it's going to explode into a million pieces just in two directions.

706
00:39:28,760 --> 00:39:32,760
All the rockets are loaded. That thing has to weigh like two tons by now.

707
00:39:32,760 --> 00:39:36,760
And remember there's 12 rockets on there for a total of 75,000 pounds of thrust.

708
00:39:36,760 --> 00:39:41,760
And this thing is going to be going 500 miles an hour. If this doesn't split the car, I don't know what will.

709
00:39:41,760 --> 00:39:44,760
Well, the safest place to be is in the bunker, so let's get inside.

710
00:39:44,760 --> 00:39:48,760
I thought one of us was going to ride it. Let's see how it goes this time and maybe next time, Buckaroo.

711
00:39:48,760 --> 00:39:50,760
Come on. Where's your sense of adventure?

712
00:39:50,760 --> 00:39:53,760
Denied a Dr. Strange Love rocket ride.

713
00:39:53,760 --> 00:39:54,760
Lockdown!

714
00:39:56,760 --> 00:39:57,760
We're ready to launch.

715
00:39:57,760 --> 00:40:00,760
Tori hunkers in the bunker with the rest of the team.

716
00:40:01,760 --> 00:40:08,760
And a strange eerie silence settles on the scene. The proverbial calm before the storm.

717
00:40:09,760 --> 00:40:21,760
This is rocket powered superplow versus front engine vehicle going at 500 miles an hour in five, four, three, two, one.

718
00:40:27,760 --> 00:40:30,760
That was one of the coolest things I've ever seen.

719
00:40:31,760 --> 00:40:34,760
That went so much faster than I thought it was going to.

720
00:40:34,760 --> 00:40:35,760
That was great.

721
00:40:35,760 --> 00:40:38,760
It was like here one second and then gone.

722
00:40:38,760 --> 00:40:48,760
Gone in a sixth of a second, the rocket's fired and 75,000 pounds of thrust throw the superplow along the track.

723
00:40:50,760 --> 00:40:54,760
The spectacular 550 miles per hour.

724
00:40:55,760 --> 00:41:00,760
And when the dust and shrapnel settle, the team discovers a spectacular result.

725
00:41:01,760 --> 00:41:02,760
We split it.

726
00:41:03,760 --> 00:41:05,760
I cannot believe we split the car in half.

727
00:41:05,760 --> 00:41:07,760
Look at it. It went right down the tape line.

728
00:41:08,760 --> 00:41:11,760
We have two perfect halves of the car.

729
00:41:11,760 --> 00:41:13,760
It actually split the engine in half.

730
00:41:13,760 --> 00:41:15,760
Yeah, check it out.

731
00:41:15,760 --> 00:41:18,760
This is what we couldn't do in Wisconsin. We split the engine block.

732
00:41:18,760 --> 00:41:22,760
Well, when you get that much force, that is crazy.

733
00:41:23,760 --> 00:41:30,760
With that complete bifurcation, the guys got exactly what they came for and what you wanted.

734
00:41:30,760 --> 00:41:32,760
Except there seems to be something missing.

735
00:41:32,760 --> 00:41:33,760
Oh, the sled.

736
00:41:33,760 --> 00:41:35,760
But where is the plow?

737
00:41:36,760 --> 00:41:38,760
The rocket went so much faster than I expected.

738
00:41:38,760 --> 00:41:39,760
It would just shoot.

739
00:41:41,760 --> 00:41:45,760
And the car, we couldn't even see it was split in two till we walked up here because there was just so much dirt in the air.

740
00:41:45,760 --> 00:41:48,760
We got up here, half a blue car, half a yellow car.

741
00:41:48,760 --> 00:41:49,760
Still can't find the wedge.

742
00:41:50,760 --> 00:41:53,760
That's because it's in a thousand tiny pieces.

743
00:41:54,760 --> 00:42:01,760
After cutting a slice through the car, the solid steel superplow disintegrated on impact with a concrete barrier.

744
00:42:05,760 --> 00:42:07,760
That was one of the coolest things I've ever seen.

745
00:42:10,760 --> 00:42:12,760
I mean, we do a lot of explosions on the show.

746
00:42:12,760 --> 00:42:18,760
We do a lot of car crashes, but I have never seen a rocket-powered superplow cut a car in half.

747
00:42:18,760 --> 00:42:21,760
And we did it. We replicated the results of this myth.

748
00:42:23,760 --> 00:42:26,760
It still busted, but we replicated the result.

749
00:42:27,760 --> 00:42:33,760
So this, my friends, is the hood of our former target car cut perfectly in half right down the line.

750
00:42:33,760 --> 00:42:36,760
Now you can only succeed in cutting the car in half.

751
00:42:36,760 --> 00:42:41,760
This myth still busted because this is the ramped-up superplow version,

752
00:42:41,760 --> 00:42:45,760
not the sort of energy you could run into on the street every day.

753
00:42:47,760 --> 00:42:49,760
I don't think we're ever going to find the wedge.

754
00:42:49,760 --> 00:42:52,760
I still cannot believe we cut a car in half.

755
00:42:52,760 --> 00:42:56,760
Well that, my friends, is the end of another excellent experiment.

756
00:43:06,760 --> 00:43:07,760
What's up, boy?

757
00:43:07,760 --> 00:43:09,760
I know that was really cool.

758
00:43:09,760 --> 00:43:13,760
And if you want to see it too, you can log on to Discovery.com slash MythBusters.

759
00:43:13,760 --> 00:43:14,760
Who's a good boy?

760
00:43:16,760 --> 00:43:18,760
You need a bath.
