1
00:00:00,000 --> 00:00:03,000
Remember, don't try this at home.

2
00:00:03,000 --> 00:00:06,000
We've got years of experience that keeps us safe.

3
00:00:09,000 --> 00:00:12,000
It's a myth revisited special.

4
00:00:12,000 --> 00:00:16,000
This may look like a salami, but it's rocket fuel.

5
00:00:16,000 --> 00:00:20,000
As the team goes head to head with disgruntled viewers,

6
00:00:20,000 --> 00:00:25,000
first they're resetting their sights on splitting an arrow.

7
00:00:25,000 --> 00:00:27,000
He hit this dead on.

8
00:00:27,000 --> 00:00:31,000
Then the bullet into water myth sinks to a new death.

9
00:00:33,000 --> 00:00:40,000
And finally, the famous Confederate rocket gets a meat makeover.

10
00:00:40,000 --> 00:00:43,000
Damn, I'm lightin' slummies, man.

11
00:00:43,000 --> 00:00:45,000
I'm makin' a rocket out of meat.

12
00:00:46,000 --> 00:00:48,000
Who are the Myth Muscles?

13
00:00:49,000 --> 00:00:50,000
Adam Savage.

14
00:00:50,000 --> 00:00:52,000
An answer all over my head, man.

15
00:00:52,000 --> 00:00:53,000
And Jamie Heidemann.

16
00:00:53,000 --> 00:00:55,000
Gets me all worked up, just lookin' at it.

17
00:00:56,000 --> 00:01:00,000
Between them, more than 30 years special effects experience.

18
00:01:01,000 --> 00:01:02,000
That was heavy.

19
00:01:02,000 --> 00:01:04,000
Joining them, Grant Imahara.

20
00:01:04,000 --> 00:01:05,000
Go get him, boy.

21
00:01:06,000 --> 00:01:07,000
Tori Belichi.

22
00:01:07,000 --> 00:01:08,000
Whoa.

23
00:01:08,000 --> 00:01:09,000
And Carrie Byron.

24
00:01:09,000 --> 00:01:11,000
That was crazy.

25
00:01:11,000 --> 00:01:13,000
They don't just tell the myths.

26
00:01:13,000 --> 00:01:16,000
They put them to the test.

27
00:01:26,000 --> 00:01:30,000
So we're about to do one of my all-time favorite things we do on the show,

28
00:01:30,000 --> 00:01:32,000
which is a revisit episode.

29
00:01:32,000 --> 00:01:40,000
And no other show that I know of ever comes to a conclusion that they are willing to reverse upon further investigation.

30
00:01:40,000 --> 00:01:45,000
And every time we do this, I think we come up with even better results and we silence our critics.

31
00:01:45,000 --> 00:01:47,000
I don't know. I think it's just a lot of whining.

32
00:01:47,000 --> 00:01:48,000
What do we have up this time?

33
00:01:48,000 --> 00:01:50,000
Bullets fired into water is a good one.

34
00:01:50,000 --> 00:01:51,000
Bullets fired into water.

35
00:01:51,000 --> 00:01:54,000
We also have Confederate rockets.

36
00:01:54,000 --> 00:01:55,000
Confederate rocket?

37
00:01:55,000 --> 00:01:56,000
Confederate rocket.

38
00:01:56,000 --> 00:01:57,000
Okay.

39
00:01:57,000 --> 00:01:58,000
And there's one more.

40
00:01:58,000 --> 00:02:00,000
The most controversial, I have to say, has got to be splitting an arrow.

41
00:02:00,000 --> 00:02:03,000
The amount of vitriol in my mailbox about that one is just crazy.

42
00:02:03,000 --> 00:02:05,000
So we're going to silence them this time?

43
00:02:05,000 --> 00:02:09,000
Not only did we get it right the first time, but this time we're going to make you sure of it.

44
00:02:09,000 --> 00:02:14,000
Well, in that case, splitting an arrow seems like a good place to start.

45
00:02:14,000 --> 00:02:18,000
In Robin Hood, Arrow Flynn made it look so easy.

46
00:02:18,000 --> 00:02:20,000
He's split fill of terror.

47
00:02:20,000 --> 00:02:23,000
A split from knock all the way to tip.

48
00:02:23,000 --> 00:02:27,000
And a split second later, the crowd went ballistic.

49
00:02:30,000 --> 00:02:31,000
Yep, ready?

50
00:02:31,000 --> 00:02:32,000
Yep.

51
00:02:32,000 --> 00:02:39,000
But when the Mythbusters emulated Arrow, their long shots were a bit of a long shot.

52
00:02:39,000 --> 00:02:41,000
Nice grouping, Grant.

53
00:02:41,000 --> 00:02:46,000
So they did a point blank test which still didn't seal the deal.

54
00:02:47,000 --> 00:02:53,000
But according to viewers, the team used the wrong bow, the wrong arrow heads, the wrong arrow shafts.

55
00:02:53,000 --> 00:02:56,000
The fans think it's still possible.

56
00:02:56,000 --> 00:02:58,000
Well, let's do it their way this time.

57
00:02:58,000 --> 00:03:06,000
We'll take all of their advice and in addition, we'll have our researchers dig up information on making our own arrows in the period materials,

58
00:03:06,000 --> 00:03:10,000
in the way that they did it at that time, and see what happens.

59
00:03:10,000 --> 00:03:15,000
So for this revisit, our sharp shooters are going to listen to the fans.

60
00:03:15,000 --> 00:03:21,000
As they build fully authentic medieval arrows, starting with the shafts.

61
00:03:23,000 --> 00:03:31,000
According to a fryer tuck load of fans, to split an arrow, it must be made of perfectly straight grain timber.

62
00:03:32,000 --> 00:03:37,000
And would you believe it, one viewer has donated the perfect piece.

63
00:03:37,000 --> 00:03:42,000
Our witness sent to us all the way from British Columbia, from Boards by George,

64
00:03:42,000 --> 00:03:47,000
and hands picked out every one of these pieces to have the straightest possible grain.

65
00:03:47,000 --> 00:03:51,000
Instead of just telling us we did it wrong, he's actually participating in this revisit.

66
00:03:51,000 --> 00:03:53,000
I love that.

67
00:03:53,000 --> 00:03:55,000
As well as I.

68
00:03:55,000 --> 00:03:57,000
I love it too.

69
00:03:59,000 --> 00:04:03,000
Good old George, but what is it that makes this cedar so special?

70
00:04:03,000 --> 00:04:07,000
As you can see it's splitting all the way down the length of the wood.

71
00:04:07,000 --> 00:04:11,000
If we make arrows out of this, this is going to be our best chance of splitting an arrow.

72
00:04:12,000 --> 00:04:17,000
That has the grain running straight through it is, so the fans reckon, ideal.

73
00:04:18,000 --> 00:04:22,000
Which means that Tori and Grant can get to grips with how to fire them.

74
00:04:22,000 --> 00:04:32,000
Here on MythBusters we like to reinvent the wheel, and apparently we chopped up our last robotic arrow firing machine to save space in the shop.

75
00:04:32,000 --> 00:04:35,000
So we need to build it again.

76
00:04:35,000 --> 00:04:40,000
The guys thought this myth was so busted, that they busted their arrow bar.

77
00:04:41,000 --> 00:04:43,000
So now they've got to make it anew.

78
00:04:43,000 --> 00:04:50,000
But ArrowBot 2 will be slightly different, so that it can fire a more authentic Robin Hood type weapon.

79
00:04:52,000 --> 00:04:57,000
We've gone from using a compound bow to a long bow, which is more traditional.

80
00:04:57,000 --> 00:05:03,000
We're trying to keep the circumstances the way they would be if you were splitting an arrow.

81
00:05:03,000 --> 00:05:07,000
And talking of arrows carries adding the finishing touches.

82
00:05:08,000 --> 00:05:14,000
I'm preparing the fletching for the arrows. It is the little feathery end of the arrows that keep it steady in flight.

83
00:05:14,000 --> 00:05:23,000
From the reference material we have, it looks as though in the Middle Ages that the feathers that would have been used would have been goose, or possibly peacock or swan.

84
00:05:23,000 --> 00:05:25,000
Most commonly goose.

85
00:05:26,000 --> 00:05:31,000
While Carrie has a gander at the fletchings, Tori's getting to the sharp end.

86
00:05:32,000 --> 00:05:37,000
There's one final thing to finish these fires. Strengthening the knock.

87
00:05:37,000 --> 00:05:40,000
So what I've got here is a goat horn.

88
00:05:40,000 --> 00:05:52,000
And the idea is that you put a split in the arrow and take a sliver of this horn, put it in there, and whip a string around to reinforce.

89
00:05:52,000 --> 00:05:58,000
The reinforced goat knock is the last addition to make the arrows completely Robin Hood compatible.

90
00:05:58,000 --> 00:06:03,000
But ironically, this may actually hinder the arrow split attempt.

91
00:06:05,000 --> 00:06:18,000
A perfectly straight grain cedar arrow may well split when hit dead on, but the goat horn in a traditional arrow could be so hard that it might block the path of the fired flyer to make a split impossible.

92
00:06:20,000 --> 00:06:24,000
But historical accuracy is what viewers wanted.

93
00:06:24,000 --> 00:06:27,000
So the strengthening horn is going to stay.

94
00:06:29,000 --> 00:06:38,000
And to complete the quest for authenticity, Tori wants to use the homemade darts, not just as the target arrows, but also as the fired flyers.

95
00:06:39,000 --> 00:06:43,000
But that will only work if they fly straight and true.

96
00:06:43,000 --> 00:06:47,000
So we just finished building our arrows, Yoli style.

97
00:06:47,000 --> 00:06:54,000
My feeling is that when we fire these things, they're probably going to explode on impact because the wood isn't that strong.

98
00:06:55,000 --> 00:06:57,000
Well, why not do a test fire?

99
00:06:58,000 --> 00:07:02,000
Fireing in three, two, one.

100
00:07:04,000 --> 00:07:06,000
A bullseye it ain't.

101
00:07:07,000 --> 00:07:08,000
Huh.

102
00:07:08,000 --> 00:07:09,000
Oh, wow.

103
00:07:10,000 --> 00:07:12,000
Well, it looked like a strong firing.

104
00:07:12,000 --> 00:07:14,000
Yeah, they don't fire so straight though.

105
00:07:14,000 --> 00:07:15,000
Not so much.

106
00:07:15,000 --> 00:07:18,000
How the hell do we get it at that angle? That's what I want to know.

107
00:07:18,000 --> 00:07:20,000
It looked almost like it hit something on the way out.

108
00:07:20,000 --> 00:07:22,000
Maybe it hit the fletching.

109
00:07:22,000 --> 00:07:25,000
Yeah, it's possible.

110
00:07:26,000 --> 00:07:30,000
The authentic arrow is about as accurate as a scud missile.

111
00:07:30,000 --> 00:07:38,000
But because the team still wants to use them as both the splitter and the split-e, it's going with the point blank test straight away.

112
00:07:38,000 --> 00:07:42,000
And Tori's in charge of the high tech aiming system.

113
00:07:43,000 --> 00:07:44,000
Ready?

114
00:07:44,000 --> 00:07:45,000
Ready?

115
00:07:45,000 --> 00:07:46,000
High speed ready?

116
00:07:46,000 --> 00:07:47,000
Go.

117
00:07:47,000 --> 00:07:49,000
Three, two, one.

118
00:07:51,000 --> 00:07:52,000
Whoa.

119
00:07:53,000 --> 00:07:55,000
That was cool.

120
00:07:55,000 --> 00:07:57,000
It was right on the money.

121
00:07:59,000 --> 00:08:00,000
But there was no split.

122
00:08:00,000 --> 00:08:03,000
The force from the bow broke the fired arrow in half.

123
00:08:03,000 --> 00:08:09,000
So for test two, they're going to try a stronger modern arrow, still aiming at the authentic target.

124
00:08:11,000 --> 00:08:12,000
Go.

125
00:08:14,000 --> 00:08:17,000
It's a tougher arrow, but the same result.

126
00:08:17,000 --> 00:08:21,000
Oh, shoot.

127
00:08:22,000 --> 00:08:29,000
The modern fires is bent as a $3 bill, yet the target arrow is virtually unscathed.

128
00:08:29,000 --> 00:08:33,000
To get the elusive split, they're going to need a plan B.

129
00:08:42,000 --> 00:08:49,000
The next revisit is from the explosive Confederate rocket, where the Mifbusters went ballistic.

130
00:08:50,000 --> 00:08:51,000
Three.

131
00:08:51,000 --> 00:08:57,000
Adam and Jamie built, aimed and launched missiles made out of Civil War era technology.

132
00:08:59,000 --> 00:09:07,000
But try as they might, they found that even their souped up hybrid retro rocket couldn't fly the mythical 120 miles.

133
00:09:12,000 --> 00:09:14,000
So you guys are revisiting Confederate rocket?

134
00:09:14,000 --> 00:09:15,000
How come?

135
00:09:15,000 --> 00:09:19,000
I mean, didn't your last three rocket systems work perfectly and you busted the myth, right?

136
00:09:19,000 --> 00:09:24,000
When we were doing the original, we came across a piece of information that we had to have a crack at.

137
00:09:24,000 --> 00:09:31,000
Apparently these hybrid rockets are so simple and effective that they'll run off of just about anything, even a salami.

138
00:09:31,000 --> 00:09:33,000
So you guys are going to fuel these rockets with salami?

139
00:09:33,000 --> 00:09:34,000
You bet.

140
00:09:37,000 --> 00:09:42,000
When it comes to rocket fuel, the Mifbusters like to think outside the box.

141
00:09:43,000 --> 00:09:46,000
It's got to be one of the strangest things we've ever done.

142
00:09:47,000 --> 00:09:50,000
I mean, I'm about to chuck a salami into the lathe.

143
00:09:51,000 --> 00:10:00,000
Sure is strange, but these hybrid rockets are so efficient that apparently any hydrocarbon, even salami, can be fuel.

144
00:10:01,000 --> 00:10:10,000
This may look like a salami, it may smell like a salami, it may even taste like a salami, but it's rocket fuel.

145
00:10:11,000 --> 00:10:18,000
While the fuel is going to be a little off the wall, everything else about their rocket is going to match their Confederate rocket blueprint.

146
00:10:21,000 --> 00:10:24,000
That Mifbusters missile was split into two halves.

147
00:10:24,000 --> 00:10:35,000
The bottom section contained the paraffin wax fuel, which, on ignition, gently smoldered until the top half's liquid nitrous oxide was added with explosive results.

148
00:10:36,000 --> 00:10:45,000
This time, they'll keep the same burn-enhancing NOx oxidizer, but replace the wax fuel with a string of sausages.

149
00:10:47,000 --> 00:10:53,000
And that's not the only change, because this time there's no need to stick to Civil War era technology.

150
00:10:53,000 --> 00:10:55,000
Yep, that's about perfect.

151
00:10:56,000 --> 00:11:01,000
They can make their salami rocket a little more refined, starting with the launch system.

152
00:11:02,000 --> 00:11:16,000
Three switches, one's going to be the fill shut-off, one will be the quick-release removal of the filling hose, and the third will be the launch button.

153
00:11:17,000 --> 00:11:21,000
They next want to modernize the way they filled a tank with nitrous oxide.

154
00:11:22,000 --> 00:11:30,000
Because last time they struggled to tell if it was filling at all, and disconnection was rather dicey.

155
00:11:33,000 --> 00:11:34,000
Are you okay?

156
00:11:34,000 --> 00:11:36,000
Yeah, I knew I was going to do that.

157
00:11:37,000 --> 00:11:41,000
So now they're going to put the tank under vacuum and draw the nitrous oxide in.

158
00:11:42,000 --> 00:11:49,000
What I've got to do here is pull a vacuum on this tank and see whether it actually sucks a sufficient amount of water into it.

159
00:11:50,000 --> 00:11:54,000
The same volume of which we'll be intending to pull in in nitrous oxide.

160
00:11:55,000 --> 00:11:59,000
It's an ingenious idea, but one worth testing out with water pre-launch.

161
00:12:06,000 --> 00:12:07,000
Success!

162
00:12:07,000 --> 00:12:09,000
The Mythbusters adore a vacuum.

163
00:12:10,000 --> 00:12:17,000
Come experiment day, they'll now be able to completely fill the NOx tank to ensure max thrust from the salami.

164
00:12:19,000 --> 00:12:26,000
Spurred on by this progress, the Mythbusters race ahead with the final touches to their lunch meat launcher.

165
00:12:27,000 --> 00:12:28,000
There's your rocket nozzle.

166
00:12:29,000 --> 00:12:30,000
That's beautiful.

167
00:12:31,000 --> 00:12:35,000
With the nozzle in place, the team joins up the two halves of the engine.

168
00:12:36,000 --> 00:12:38,000
That is so light.

169
00:12:39,000 --> 00:12:41,000
A shiny rocket hull later.

170
00:12:42,000 --> 00:12:44,000
And that is that.

171
00:12:44,000 --> 00:12:50,000
One hybrid rocket with nitrous oxide as the oxidizer and salami as the fuel.

172
00:12:51,000 --> 00:12:52,000
Okay, go for it.

173
00:12:53,000 --> 00:12:54,000
And...

174
00:12:57,000 --> 00:12:58,000
That is great.

175
00:12:59,000 --> 00:13:00,000
Okay.

176
00:13:00,000 --> 00:13:01,000
I love it.

177
00:13:01,000 --> 00:13:03,000
It sure is lovely, but will it work?

178
00:13:04,000 --> 00:13:12,000
Well, before heading to mission control in the desert, Jamie and Adam are first going to put their meat missile through a locked down test fire at Alameda.

179
00:13:13,000 --> 00:13:17,000
You got your pepperoni, you got your salami, you got bologna.

180
00:13:17,000 --> 00:13:18,000
So I can't get a veggie?

181
00:13:18,000 --> 00:13:20,000
No, no veggie rockets.

182
00:13:20,000 --> 00:13:21,000
Sorry.

183
00:13:21,000 --> 00:13:22,000
How much?

184
00:13:22,000 --> 00:13:27,000
Pyrotechnician Jack Morocco is here because he has a license to pack black powder.

185
00:13:27,000 --> 00:13:32,000
So Jack, can I set you up with helping us manufacture the salami rocket engines?

186
00:13:32,000 --> 00:13:35,000
Absolutely, I just hope I don't get too hungry.

187
00:13:36,000 --> 00:13:43,000
If the salamis are going to burn explosively when the nox is added, they first need to be on fire.

188
00:13:43,000 --> 00:13:47,000
And a small coating of gunpowder should do just the job.

189
00:13:48,000 --> 00:13:49,000
Let's just see what it does.

190
00:13:49,000 --> 00:13:50,000
All right.

191
00:13:50,000 --> 00:13:51,000
Okay.

192
00:13:51,000 --> 00:13:52,000
Ready to go?

193
00:13:54,000 --> 00:13:55,000
Whoa!

194
00:13:55,000 --> 00:13:56,000
It's a movie.

195
00:13:57,000 --> 00:14:02,000
Eight salami rolls later and it's time to play hide the sausage.

196
00:14:03,000 --> 00:14:04,000
Last one.

197
00:14:06,000 --> 00:14:12,000
With the motor packed and loaded, the rocket is locked down so that it can ignite but can't take off.

198
00:14:14,000 --> 00:14:16,000
And then it's all systems go.

199
00:14:17,000 --> 00:14:21,000
This is another one of those things where you just run through so many of the safety procedures

200
00:14:21,000 --> 00:14:25,000
and so many of the systems in your head that every now and then you have to remind yourself

201
00:14:25,000 --> 00:14:28,000
and go, damn, I'm lighting salamis, man.

202
00:14:28,000 --> 00:14:30,000
I'm making a rocket out of meat.

203
00:14:30,000 --> 00:14:34,000
But will it make minced meat of this myth?

204
00:14:34,000 --> 00:14:38,000
This proof of concept static test of the salami rocket.

205
00:14:38,000 --> 00:14:40,000
I'm going to release the nitrous oxide.

206
00:14:41,000 --> 00:14:42,000
Off she goes.

207
00:14:42,000 --> 00:14:43,000
All right.

208
00:14:43,000 --> 00:14:48,000
In three, two, one, launch and shut up.

209
00:14:53,000 --> 00:14:54,000
What was that?

210
00:14:54,000 --> 00:14:55,000
The rocket is gone.

211
00:14:56,000 --> 00:14:57,000
No way.

212
00:14:57,000 --> 00:15:01,000
No, not gone up in the air, Adam, but gone to the dogs.

213
00:15:02,000 --> 00:15:03,000
Oh, what?

214
00:15:03,000 --> 00:15:04,000
Did it blow up?

215
00:15:04,000 --> 00:15:05,000
Yeah.

216
00:15:05,000 --> 00:15:06,000
The engine's gone.

217
00:15:06,000 --> 00:15:07,000
No.

218
00:15:08,000 --> 00:15:13,000
Their notorious PIG wasn't a rocket, but it sure was a blast.

219
00:15:13,000 --> 00:15:16,000
The place looks like a massacre in a deli.

220
00:15:16,000 --> 00:15:18,000
Time for a post-mortem.

221
00:15:18,000 --> 00:15:24,000
What I saw when Adam pushed the button was that there was flame coming out of the bottom of the rocket.

222
00:15:24,000 --> 00:15:28,000
That meant that the ignition worked, the black powder worked and it lit.

223
00:15:28,000 --> 00:15:32,000
And then there was a pause when the nitrous oxide was opened.

224
00:15:33,000 --> 00:15:36,000
And then it was just gone.

225
00:15:43,000 --> 00:15:47,000
Amazingly, the salami fuel was too powerful.

226
00:15:47,000 --> 00:15:53,000
As it burned, there was an excess of exhaust and the pressure built up until kaboom.

227
00:15:55,000 --> 00:16:00,000
For the boys to get some pastrami propulsion, it's back to the drawing board.

228
00:16:01,000 --> 00:16:05,000
Let's get some brooms and start cleaning up this carnage assata.

229
00:16:05,000 --> 00:16:08,000
There's meat everywhere. Disgusting.

230
00:16:12,000 --> 00:16:19,000
Back with splitting an arrow, the team is going crazy with deja vu as it attempts to bust this myth once again.

231
00:16:20,000 --> 00:16:27,000
Despite making the most splitable arrow possible and using a traditional bow with a 90-pound draw,

232
00:16:27,000 --> 00:16:30,000
their point blank shot failed miserably.

233
00:16:30,000 --> 00:16:32,000
And Grant knows why.

234
00:16:33,000 --> 00:16:42,000
At that range, we're putting a huge amount of force in the arrow and that's why they're either breaking or in the case of the aluminum arrow, bending.

235
00:16:42,000 --> 00:16:46,000
So I think we actually need to go back to doing a range test.

236
00:16:46,000 --> 00:16:53,000
Let the arrow fly. That way, we're not pushing on it to try and push through the other arrow.

237
00:16:53,000 --> 00:17:00,000
With their point blank test chaffed, the archery range is the perfect place to test this myth once and for all.

238
00:17:02,000 --> 00:17:09,000
And as in their recent test, they're going to use their authentic arrows as the target, but modern arrows to fire.

239
00:17:10,000 --> 00:17:17,000
The important thing is that we're using the replica arrows as the target arrow because it's really not going to matter the arrow that goes into it.

240
00:17:17,000 --> 00:17:22,000
Half as much as it matters that the arrow it's going into is made with period materials.

241
00:17:22,000 --> 00:17:25,000
Here we go in three, two, one.

242
00:17:25,000 --> 00:17:32,000
Close, but not close enough. Of course, they can only split the arrow if they actually hit it.

243
00:17:32,000 --> 00:17:35,000
So they dial in the focus.

244
00:17:35,000 --> 00:17:38,000
Here we go. Three, two, one.

245
00:17:40,000 --> 00:17:43,000
You know, I think we hit it because it's definitely off target.

246
00:17:43,000 --> 00:17:48,000
Sure enough, this time they got a direct hit, but no splitting.

247
00:17:48,000 --> 00:17:52,000
And that's the same story for their next five fires.

248
00:17:52,000 --> 00:17:58,000
Hit after hit, but no knock to tip split, which is all a little familiar.

249
00:17:58,000 --> 00:18:02,000
When these guys first tested this myth, they filmed something surprising.

250
00:18:02,000 --> 00:18:06,000
Straight as an arrow is not how arrows actually fly.

251
00:18:06,000 --> 00:18:12,000
They bend and wobble through the air, which makes getting a split almost impossible.

252
00:18:12,000 --> 00:18:20,000
The same thing is happening here, but the team got too many vitriolic emails to abandon this myth now.

253
00:18:20,000 --> 00:18:24,000
Somehow I feel like this has happened before.

254
00:18:24,000 --> 00:18:32,000
Something reminding you of something like we may have done this once.

255
00:18:32,000 --> 00:18:36,000
They're not giving up without a fight.

256
00:18:40,000 --> 00:18:46,000
We couldn't do a myth revisited without one gun story, so here it is.

257
00:18:46,000 --> 00:18:51,000
So, bolts fired into water. What did we do wrong with that one? I thought we did great.

258
00:18:51,000 --> 00:18:56,000
You did do great, but the viewers, in addition to all that testing, would have liked to have seen us fire guns underwater.

259
00:18:56,000 --> 00:19:01,000
That might get past the bullet hitting the water deceleration problem that we were having.

260
00:19:01,000 --> 00:19:05,000
It's another opportunity to break out the guns, I guess, huh?

261
00:19:05,000 --> 00:19:11,000
Last time, the myth musters broke out guns galore to see if bullets really are stopped by water.

262
00:19:11,000 --> 00:19:17,000
This is M1 Grand 30 caliber at 2 feet.

263
00:19:17,000 --> 00:19:22,000
And the results were surprising. The more powerful the gun...

264
00:19:22,000 --> 00:19:26,000
This kills you. This kills you and everyone else in the room.

265
00:19:26,000 --> 00:19:30,000
The more ineffective the bullet in water.

266
00:19:30,000 --> 00:19:39,000
Fans were happy with these findings, but now want to know whether guns actually work when submerged.

267
00:19:39,000 --> 00:19:45,000
To find out, Tori, Carrie and Grant are going to build a water trough, drown their weapons,

268
00:19:45,000 --> 00:19:50,000
and see at what distance they penetrate a block of ballistics material.

269
00:19:50,000 --> 00:19:58,000
King Cobra. Six hour P239, 9mm. M1 Grand.

270
00:19:58,000 --> 00:20:02,000
Personal favorite, 12 gauge shotgun.

271
00:20:02,000 --> 00:20:10,000
Of course, there are special forces guns like the Glock 17 or the SPP-1 that can fire underwater.

272
00:20:10,000 --> 00:20:14,000
But this myth is about regular weapons like these.

273
00:20:14,000 --> 00:20:21,000
Will any of them shoot from the hip when submerged in Tori's newly reinforced water filled trough?

274
00:20:21,000 --> 00:20:26,000
Alright, here we are, main event. We're about to fire a bullet underneath the water.

275
00:20:26,000 --> 00:20:30,000
What I need to do is I need to open the chamber of the gun to make sure there's no air at all in the barrel.

276
00:20:30,000 --> 00:20:39,000
The gun must be air free because otherwise it could explode if the bullet passes from air to water inside the barrel.

277
00:20:39,000 --> 00:20:44,000
Okay, we are loaded and ready to fire.

278
00:20:44,000 --> 00:20:49,000
For each gun they want to know two things. Over what distance is it lethal?

279
00:20:49,000 --> 00:20:54,000
But before that, will it even fire underwater?

280
00:20:54,000 --> 00:20:59,000
9mm, first shot. Three, two, one.

281
00:20:59,000 --> 00:21:04,000
That looked cool. I think I might have made it all the way.

282
00:21:04,000 --> 00:21:07,000
That was rad. The whole water just like leaped up.

283
00:21:07,000 --> 00:21:12,000
I think it went far. There it is. I'd say that was about 18 feet.

284
00:21:12,000 --> 00:21:16,000
And the bullet is perfectly intact.

285
00:21:16,000 --> 00:21:21,000
One thing we're just kind of skipping over is we've just proven that you can fire a bullet underneath water.

286
00:21:21,000 --> 00:21:23,000
Oh, you're right.

287
00:21:23,000 --> 00:21:28,000
So right there it's confirmed. It's possible to shoot a gun underneath water.

288
00:21:28,000 --> 00:21:36,000
Test one's passed. A 9mm will fire underwater. But as Grant discovers, it won't reload.

289
00:21:36,000 --> 00:21:41,000
Check it out. When I was resetting the ransom rest, I found the shell casing caught in the slide.

290
00:21:41,000 --> 00:21:43,000
It didn't eject the bullet.

291
00:21:43,000 --> 00:21:45,000
No, because it relies on the pressure.

292
00:21:45,000 --> 00:21:47,000
Right, and you have that water on top of it.

293
00:21:47,000 --> 00:21:50,000
So if you're shooting underwater, you only have one shot to kill the bad guy.

294
00:21:50,000 --> 00:21:52,000
Yep, you better get it right.

295
00:21:52,000 --> 00:21:57,000
So you've got one shot, but over what distance is it life-threatening?

296
00:21:57,000 --> 00:21:59,000
In the original story...

297
00:21:59,000 --> 00:22:03,000
Okay, this 9mm pistol at 8 feet.

298
00:22:03,000 --> 00:22:09,000
Adam and Jamie showed you'd have to dive 8 feet to survive a shot from a 9mm.

299
00:22:09,000 --> 00:22:13,000
When it's fired into water from air.

300
00:22:13,000 --> 00:22:15,000
Whoa, no, that didn't go all the way through.

301
00:22:15,000 --> 00:22:19,000
But what about when it's in the water to begin with?

302
00:22:19,000 --> 00:22:25,000
From the barrel to the ballistic material with 10 feet, we're going with another 9mm round full metal jacket.

303
00:22:25,000 --> 00:22:28,000
In 3, 2, 1...

304
00:22:28,000 --> 00:22:31,000
Another fire, but was it lethal?

305
00:22:31,000 --> 00:22:34,000
So it didn't even have the penetration of a BB?

306
00:22:34,000 --> 00:22:35,000
No.

307
00:22:35,000 --> 00:22:36,000
Not lethal?

308
00:22:36,000 --> 00:22:37,000
Not at 10 feet.

309
00:22:37,000 --> 00:22:39,000
Alright, why don't we do 2 feet, see what happens there.

310
00:22:39,000 --> 00:22:41,000
Great.

311
00:22:41,000 --> 00:22:43,000
9mm at 2 feet?

312
00:22:43,000 --> 00:22:45,000
Oh yeah.

313
00:22:45,000 --> 00:22:50,000
But this time, when they look for the round, there's a problem.

314
00:22:50,000 --> 00:22:52,000
It's nowhere to be found.

315
00:22:52,000 --> 00:22:55,000
There's no obvious hole in the ballistic's material.

316
00:22:55,000 --> 00:22:57,000
Oh, it's the magic bullet.

317
00:22:57,000 --> 00:22:58,000
It's a disappearing bullet.

318
00:22:58,000 --> 00:23:00,000
It disappeared.

319
00:23:00,000 --> 00:23:02,000
And it's not tucked away in the trough.

320
00:23:02,000 --> 00:23:04,000
I don't see it in here.

321
00:23:04,000 --> 00:23:06,000
It's all a bit of a mystery.

322
00:23:06,000 --> 00:23:09,000
At 2 feet, we couldn't find the bullet.

323
00:23:09,000 --> 00:23:18,000
So what we're going to have to do is dissect the ballistic's material block at the end of the experiment and see if we can find it.

324
00:23:18,000 --> 00:23:21,000
Right now, we're going to move on to the .357.

325
00:23:21,000 --> 00:23:24,000
There's no time to stop and search.

326
00:23:24,000 --> 00:23:29,000
With the light fading fast, the team must crack on with the rest of their weaponry.

327
00:23:29,000 --> 00:23:30,000
OK.

328
00:23:30,000 --> 00:23:35,000
.357 Magnum Full Metal Jacket in 3, 2, 1.

329
00:23:35,000 --> 00:23:38,000
Was that a bigger boom?

330
00:23:38,000 --> 00:23:41,000
I don't see a big hole.

331
00:23:41,000 --> 00:23:43,000
Bigger boom, same problem.

332
00:23:43,000 --> 00:23:46,000
The round is nowhere to be seen.

333
00:23:46,000 --> 00:23:48,000
No bullets.

334
00:23:48,000 --> 00:23:52,000
The .357 sure works underwater.

335
00:23:52,000 --> 00:23:57,000
But it's deadliness is going to need some further dissection.

336
00:24:00,000 --> 00:24:06,000
In the Confederate rocket revisit, Adam and Jamie have had a Salami setback.

337
00:24:06,000 --> 00:24:12,000
Their mythical meat missile was more of a baloney boom.

338
00:24:12,000 --> 00:24:14,000
So how did the Salami powered rockets go?

339
00:24:14,000 --> 00:24:15,000
It didn't go.

340
00:24:15,000 --> 00:24:17,000
It catastrophically failed on the launch pad.

341
00:24:17,000 --> 00:24:19,000
Well, that doesn't sound like a failure.

342
00:24:19,000 --> 00:24:21,000
But I guess you do need to make a rocket.

343
00:24:21,000 --> 00:24:23,000
So what are you going to do next?

344
00:24:23,000 --> 00:24:27,000
We learned that there is enough energy in a Salami to cause an explosion.

345
00:24:27,000 --> 00:24:30,000
So that means there ought to be enough energy to launch a rocket.

346
00:24:30,000 --> 00:24:32,000
We just need to refine it a little bit.

347
00:24:32,000 --> 00:24:38,000
And I had to thought that we could possibly make a smaller version using paintball gun tanks

348
00:24:38,000 --> 00:24:41,000
that we could get together pretty quickly.

349
00:24:41,000 --> 00:24:46,000
So they're shrinking things down to two small paintball tanks joined by a valve.

350
00:24:46,000 --> 00:24:49,000
The top tank will be filled with liquid nitrous oxide.

351
00:24:49,000 --> 00:24:53,000
And the bottom stuffed with a solitary Salami.

352
00:24:53,000 --> 00:24:57,000
It's a mad rush because the boys are well behind schedule.

353
00:24:57,000 --> 00:25:02,000
Luckily, the advantage of this new design is that it's easy to put together.

354
00:25:03,000 --> 00:25:05,000
Rocket nozzle.

355
00:25:06,000 --> 00:25:09,000
One Salami later and the new rocket is ready.

356
00:25:11,000 --> 00:25:14,000
And after four sweaty hours...

357
00:25:15,000 --> 00:25:17,000
You think we're ready to pack out?

358
00:25:18,000 --> 00:25:19,000
I think we're ready.

359
00:25:20,000 --> 00:25:25,000
At last for the great Salami showdown, it's off to the middle of nowhere.

360
00:25:30,000 --> 00:25:33,000
When Adam and Jamie fired their shotgun into water...

361
00:25:33,000 --> 00:25:34,000
One!

362
00:25:35,000 --> 00:25:38,000
They found that it was deadly at a distance of 10 feet.

363
00:25:38,000 --> 00:25:39,000
Jesus wet, Jamie.

364
00:25:39,000 --> 00:25:41,000
That's definitely a lethal hit.

365
00:25:41,000 --> 00:25:44,000
But what about when the gun is already under?

366
00:25:44,000 --> 00:25:45,000
Okay.

367
00:25:45,000 --> 00:25:50,000
Shotgun at 10 feet underwater in three, two, one.

368
00:25:53,000 --> 00:25:56,000
Just like the handguns, there's fire in the hole.

369
00:25:56,000 --> 00:25:59,000
But this time, there is a difference.

370
00:26:00,000 --> 00:26:02,000
Look at that. It cracked all the way.

371
00:26:02,000 --> 00:26:05,000
The gun has exploded in half.

372
00:26:05,000 --> 00:26:08,000
Now do you think that's because there was air in there somewhere

373
00:26:08,000 --> 00:26:11,000
or it's just a really bad idea to shoot shotgun underwater?

374
00:26:11,000 --> 00:26:13,000
I think it's a bad idea to shoot shotgun underwater.

375
00:26:13,000 --> 00:26:15,000
I doubt seriously there's any air in there.

376
00:26:15,000 --> 00:26:17,000
What a shame.

377
00:26:17,000 --> 00:26:19,000
So shotgun hunting underwater?

378
00:26:19,000 --> 00:26:20,000
It's stupid.

379
00:26:22,000 --> 00:26:25,000
With the shotgun sunk, there's one rifle remaining.

380
00:26:26,000 --> 00:26:29,000
Up next, we have the M1 Garand,

381
00:26:29,000 --> 00:26:34,000
which actually has the exit velocity of 2,700 feet per second,

382
00:26:34,000 --> 00:26:38,000
which is basically like three times the energy of any of the guns we've shot today.

383
00:26:38,000 --> 00:26:41,000
Last time, the super fast M1's bullet...

384
00:26:41,000 --> 00:26:42,000
...blast.

385
00:26:42,000 --> 00:26:45,000
...disintegrated virtually on impact with the water.

386
00:26:48,000 --> 00:26:52,000
But now, when under, will it make you drown your sorrows?

387
00:26:53,000 --> 00:26:57,000
M1 Garand in three, two, one.

388
00:26:59,000 --> 00:27:01,000
That was a good one.

389
00:27:02,000 --> 00:27:05,000
The gun's in one piece, but the bullet...

390
00:27:05,000 --> 00:27:07,000
Here's the bullet.

391
00:27:07,000 --> 00:27:08,000
Right there?

392
00:27:08,000 --> 00:27:09,000
Yep.

393
00:27:09,000 --> 00:27:11,000
What is that? What is that, about six feet?

394
00:27:11,000 --> 00:27:12,000
Yeah.

395
00:27:12,000 --> 00:27:13,000
What do you think?

396
00:27:13,000 --> 00:27:15,000
Around six feet, unless your point blank.

397
00:27:15,000 --> 00:27:17,000
I don't think this thing's lethal.

398
00:27:17,000 --> 00:27:19,000
Wait, it fell at six feet.

399
00:27:19,000 --> 00:27:21,000
Yeah, and it didn't even make it to our target.

400
00:27:21,000 --> 00:27:24,000
This time, the bullet hasn't shattered.

401
00:27:24,000 --> 00:27:28,000
But it's still being rendered ineffective by water.

402
00:27:28,000 --> 00:27:30,000
I would say, though, it's pretty intimidating.

403
00:27:30,000 --> 00:27:33,000
I think if somebody was shooting one of those at me underwater

404
00:27:33,000 --> 00:27:36,000
and saw that explosion, I'd still be freaking out.

405
00:27:36,000 --> 00:27:39,000
Frightening for sure, but just a few kicks away,

406
00:27:39,000 --> 00:27:44,000
and the water will prevent the M1's bullet from spilling your blood.

407
00:27:46,000 --> 00:27:49,000
But can the same be said of the handguns?

408
00:27:50,000 --> 00:27:53,000
We're back at the shop now, and we've taken our block of ballistic material,

409
00:27:53,000 --> 00:27:57,000
and we need to dissect it because we didn't find any bullets or any bullet holes,

410
00:27:57,000 --> 00:28:01,000
and we want to find out if there might be one lodged in there that we can't see.

411
00:28:01,000 --> 00:28:02,000
You guys find anything?

412
00:28:02,000 --> 00:28:03,000
No.

413
00:28:03,000 --> 00:28:05,000
There's no holes. There's nothing.

414
00:28:05,000 --> 00:28:09,000
Okay, do you... Let's take this off and just start cutting into it.

415
00:28:09,000 --> 00:28:11,000
Slice and dice.

416
00:28:11,000 --> 00:28:12,000
Yeah, sounds good.

417
00:28:13,000 --> 00:28:17,000
It's a careful operation as the team carves off one layer at a time,

418
00:28:17,000 --> 00:28:22,000
but it's beginning to look like the handgun rounds didn't even make it in.

419
00:28:23,000 --> 00:28:24,000
There's nothing in here.

420
00:28:24,000 --> 00:28:25,000
Looks clean.

421
00:28:25,000 --> 00:28:26,000
Yeah.

422
00:28:28,000 --> 00:28:29,000
Until...

423
00:28:30,000 --> 00:28:32,000
Wait, wait, wait. I feel something.

424
00:28:32,000 --> 00:28:33,000
Hey.

425
00:28:34,000 --> 00:28:36,000
Hey! There it is.

426
00:28:36,000 --> 00:28:37,000
It's the 9mm.

427
00:28:37,000 --> 00:28:38,000
It's the 9.

428
00:28:38,000 --> 00:28:39,000
It's the 9.

429
00:28:39,000 --> 00:28:43,000
I'm two inches from the back, which means I've penetrated four inches deep.

430
00:28:44,000 --> 00:28:45,000
That's lethal.

431
00:28:45,000 --> 00:28:48,000
Well, let's keep cutting it, because we still don't have the 357.

432
00:28:48,000 --> 00:28:54,000
The 357 Magnum is more powerful than the 9mm, so the team keeps cutting deeper.

433
00:28:54,000 --> 00:28:55,000
Wait.

434
00:28:55,000 --> 00:28:56,000
Here's the other one.

435
00:28:56,000 --> 00:28:57,000
How deep is that?

436
00:28:57,000 --> 00:28:58,000
Wow.

437
00:28:58,000 --> 00:29:00,000
That went almost all the way through.

438
00:29:00,000 --> 00:29:03,000
I would say that's about 5.5, 5.75 inches.

439
00:29:03,000 --> 00:29:04,000
Yeah.

440
00:29:05,000 --> 00:29:11,000
So at two feet, the Magnum, like the other handgun, will send you to a watery grave.

441
00:29:12,000 --> 00:29:15,000
So guys, bullets fired underwater, how did you do?

442
00:29:15,000 --> 00:29:19,000
Well, Jamie, you can actually fire a handgun or a rifle underneath water.

443
00:29:19,000 --> 00:29:21,000
But not a shotgun.

444
00:29:21,000 --> 00:29:23,000
Well, what happens to the shotgun?

445
00:29:23,000 --> 00:29:24,000
Blows up.

446
00:29:24,000 --> 00:29:25,000
Hmm.

447
00:29:25,000 --> 00:29:27,000
My young friend, were they lethal?

448
00:29:27,000 --> 00:29:30,000
Neither of them were lethal at a distance of more than three feet.

449
00:29:30,000 --> 00:29:33,000
It's actually more lethal to fire into water than underwater.

450
00:29:33,000 --> 00:29:37,000
So what are you guys going to call this, busted, plausible, or confirmed?

451
00:29:37,000 --> 00:29:38,000
Confirmed.

452
00:29:38,000 --> 00:29:39,000
You can fire a gun underwater.

453
00:29:39,000 --> 00:29:40,000
Yes.

454
00:29:40,000 --> 00:29:41,000
Well, nice work, guys.

455
00:29:41,000 --> 00:29:42,000
Thanks.

456
00:29:42,000 --> 00:29:43,000
Thanks.

457
00:29:52,000 --> 00:29:56,000
Back with splitting an arrow, the team has fired over 30 shots.

458
00:29:57,000 --> 00:30:02,000
But so far, the authentic and made target arrow has failed to split it all.

459
00:30:04,000 --> 00:30:06,000
And Tari thinks he knows why.

460
00:30:07,000 --> 00:30:12,000
Should we take the horn out so that we're giving ourselves the best chance of splitting this arrow?

461
00:30:12,000 --> 00:30:14,000
Yeah, we could certainly try that.

462
00:30:14,000 --> 00:30:18,000
I mean, that's how it was described in the historical text.

463
00:30:18,000 --> 00:30:22,000
Let's just try to make our critics happy, because I'm tired of arguing with them anyway.

464
00:30:22,000 --> 00:30:28,000
Might as well take out the bone so that if it really still doesn't split it, then we could go out.

465
00:30:28,000 --> 00:30:35,000
As predicted, the traditional horny knock is so strong that the fired arrow gets diverted off target.

466
00:30:37,000 --> 00:30:41,000
So Grant's taking out the horn, which may help split the arrow,

467
00:30:41,000 --> 00:30:45,000
but makes this experiment no longer Robin Hood compatible.

468
00:30:46,000 --> 00:30:47,000
There's your problem.

469
00:30:52,000 --> 00:30:54,000
Salami sure is popular.

470
00:30:54,000 --> 00:31:01,000
2,500 tons of this innocuous looking meat medley is eaten every year.

471
00:31:01,000 --> 00:31:04,000
But can it do more than just power our bodies?

472
00:31:04,000 --> 00:31:08,000
Can it fuel something altogether more spectacular?

473
00:31:09,000 --> 00:31:13,000
Well, the myth musters have come to the middle of nowhere to find out.

474
00:31:14,000 --> 00:31:15,000
It's dawn.

475
00:31:15,000 --> 00:31:16,000
It's freezing.

476
00:31:16,000 --> 00:31:22,000
And we're back on the original launch site of the Confederate rocket, except this time with the Salami powered rocket.

477
00:31:22,000 --> 00:31:26,000
Yeah, we know from the first test that we did that the energy is there.

478
00:31:26,000 --> 00:31:32,000
Hopefully we figured out how to harness it in such a way that it actually propels the rocket instead of explodes it.

479
00:31:32,000 --> 00:31:36,000
So what do you think? Should we get into it?

480
00:31:36,000 --> 00:31:37,000
Yeah, let's just go.

481
00:31:37,000 --> 00:31:38,000
All right.

482
00:31:38,000 --> 00:31:43,000
Just like at Alameda, they're going to position the rocket 500 feet away,

483
00:31:43,000 --> 00:31:47,000
crouch behind safety glass, and hope for the best.

484
00:31:47,000 --> 00:31:50,000
But this time they've got a secret weapon.

485
00:31:51,000 --> 00:31:54,000
Rocket expert Eric Gates is here to help them.

486
00:31:55,000 --> 00:31:57,000
Eric is a regular myth-keteer.

487
00:31:57,000 --> 00:32:01,000
It was his rockets that gave the thrust to the famous rocket car.

488
00:32:04,000 --> 00:32:09,000
And without him, a full 360 degree ride around a swing set would have been impossible.

489
00:32:10,000 --> 00:32:15,000
This time he's already altering Adam and Janie's plans.

490
00:32:17,000 --> 00:32:22,000
Eric wants to replace the black powder ignition system with modern hobby rocket fuel.

491
00:32:22,000 --> 00:32:27,000
And as usual, he can't resist a demonstration to show why.

492
00:32:27,000 --> 00:32:35,000
Your black powder is a quick flash, whereas this AP will burn for about three or four seconds with the constant heat to get the fuel hot for the nitrous.

493
00:32:35,000 --> 00:32:36,000
Okay.

494
00:32:36,000 --> 00:32:38,000
So if you want to push that button.

495
00:32:38,000 --> 00:32:41,000
Three, two, one.

496
00:32:44,000 --> 00:32:45,000
That's beautiful.

497
00:32:45,000 --> 00:32:46,000
That's what I wanted to see.

498
00:32:46,000 --> 00:32:52,000
It's making a nice jet down the throat of even that small donut, which will ignite the length of the sausage.

499
00:32:52,000 --> 00:32:58,000
The hobby fuel should do a much better job at setting the salami alight before the nox is added.

500
00:32:59,000 --> 00:33:00,000
Need as a whistle.

501
00:33:01,000 --> 00:33:08,000
And as for the nox, they've abandoned the vacuum filling system as they fill her up the old fashioned way.

502
00:33:09,000 --> 00:33:14,000
A fancy finned rocket hull later and she's taken to ground zero.

503
00:33:14,000 --> 00:33:18,000
Everybody is aware that we're about to go hot over.

504
00:33:18,000 --> 00:33:19,000
Go ahead and make the system hot.

505
00:33:19,000 --> 00:33:25,000
Here in Mojave, the mythbusters have flight clearance up to 50,000 feet.

506
00:33:25,000 --> 00:33:29,000
So how high might this pastrami puppy soar?

507
00:33:30,000 --> 00:33:31,000
What's going to happen?

508
00:33:31,000 --> 00:33:34,000
I give it a 20% chance of blowing up right on the stand.

509
00:33:34,000 --> 00:33:39,000
About a 50% chance of launching somewhere under 20 or 30 feet.

510
00:33:39,000 --> 00:33:44,000
And the rest is that it's going to go maybe to a couple thousand feet.

511
00:33:44,000 --> 00:33:47,000
What we have to get here is an actual flight.

512
00:33:47,000 --> 00:33:53,000
Personally, I'm not going to be satisfied if it just gets off the launch rod and goes 10 feet in the air.

513
00:33:53,000 --> 00:33:56,000
I mean, technically that's a flight.

514
00:33:56,000 --> 00:34:00,000
I think it's going to go hundreds of feet if not thousands of feet in the air.

515
00:34:00,000 --> 00:34:09,000
Okay, so this is a salami rocket with a half inch nozzle firing in three, two, one.

516
00:34:09,000 --> 00:34:10,000
Boom.

517
00:34:12,000 --> 00:34:14,000
Hey!

518
00:34:15,000 --> 00:34:16,000
Look at that!

519
00:34:17,000 --> 00:34:18,000
20 feet, man!

520
00:34:18,000 --> 00:34:19,000
What did I tell you?

521
00:34:19,000 --> 00:34:21,000
I don't care, man.

522
00:34:21,000 --> 00:34:26,000
What anybody says, that was a salami rocket and it flew.

523
00:34:26,000 --> 00:34:28,000
Everything else is in material.

524
00:34:29,000 --> 00:34:34,000
Fly it did, but this being mythbusters, we can't leave it at 20 feet.

525
00:34:40,000 --> 00:34:46,000
In Split Arrow, Tari, Kari and Grant have been giving the Robin Hood myth their best shot.

526
00:34:46,000 --> 00:34:50,000
Yet, whatever they've tried, singles are bunches.

527
00:34:51,000 --> 00:34:57,000
They failed to split even that hair, but they've got one more trick up their sleeve.

528
00:34:57,000 --> 00:35:00,000
And here he is, Jim Long.

529
00:35:05,000 --> 00:35:06,000
This is great.

530
00:35:06,000 --> 00:35:12,000
I mean, that was one of the things that the viewers were saying is, why don't you get a professional shooter in?

531
00:35:12,000 --> 00:35:14,000
I don't know, man. This is working out perfect.

532
00:35:14,000 --> 00:35:15,000
This is it.

533
00:35:15,000 --> 00:35:20,000
Jim is one of the best archers in the land, and this myth is now down to him.

534
00:35:22,000 --> 00:35:26,000
He knocked the sticker off the end.

535
00:35:26,000 --> 00:35:32,000
It's a pretty good start from our Robin Hood wannabe, and the team goes in for a closer look.

536
00:35:32,000 --> 00:35:34,000
It's split at all.

537
00:35:34,000 --> 00:35:38,000
You took out the fletching on this side.

538
00:35:38,000 --> 00:35:40,000
You split a little bit of the wood.

539
00:35:40,000 --> 00:35:44,000
If that's his cider, what's he gonna do when he gets his eye in?

540
00:35:46,000 --> 00:35:47,000
There's the other feather.

541
00:35:49,000 --> 00:35:50,000
He's good.

542
00:35:51,000 --> 00:35:54,000
The arrow's getting shredded, but not split.

543
00:35:55,000 --> 00:36:03,000
Jim's pinpoint accuracy allows him to get hit after hit, but even he can only get partial splits at best.

544
00:36:03,000 --> 00:36:05,000
It's just getting deflected.

545
00:36:05,000 --> 00:36:06,000
Until...

546
00:36:10,000 --> 00:36:11,000
Dang.

547
00:36:11,000 --> 00:36:12,000
It's brutal.

548
00:36:12,000 --> 00:36:14,000
Oh, look at that.

549
00:36:14,000 --> 00:36:15,000
We got a split.

550
00:36:15,000 --> 00:36:16,000
Look at that.

551
00:36:16,000 --> 00:36:18,000
Almost like 10 inches long.

552
00:36:18,000 --> 00:36:20,000
That's about a third of the way down the arrow.

553
00:36:20,000 --> 00:36:28,000
It's taken over 60 direct hits to get the biggest split yet, but it's still only one-third of the arrow's length.

554
00:36:29,000 --> 00:36:33,000
I think this is the closest we'll ever be able to come to splitting it.

555
00:36:33,000 --> 00:36:34,000
I mean, look.

556
00:36:34,000 --> 00:36:35,000
Okay.

557
00:36:35,000 --> 00:36:37,000
I mean, it came in very, very cleanly.

558
00:36:37,000 --> 00:36:44,000
You can see it following straight down the grain until it gets to about here, and then it starts to go off kilter.

559
00:36:44,000 --> 00:36:46,000
He hit this dead on.

560
00:36:46,000 --> 00:36:47,000
We can do this all day.

561
00:36:47,000 --> 00:36:49,000
I don't think we're gonna get a better shot than this.

562
00:36:49,000 --> 00:36:54,000
How can you get a better shot than dead on with carbon fiber arrows?

563
00:36:54,000 --> 00:36:55,000
Yeah, there's no way.

564
00:36:55,000 --> 00:36:56,000
It's busted.

565
00:36:56,000 --> 00:37:07,000
Given that the team made the most splitable arrow possible and a whole day's worth of fires have failed to yield a not-to-tip split, this myth is busted again.

566
00:37:07,000 --> 00:37:10,000
So how did they do it in the movie?

567
00:37:10,000 --> 00:37:17,000
So we're switching to bamboo because we think that in the Robin Hood movie, in order to fake the splitting arrow,

568
00:37:17,000 --> 00:37:22,000
they used something with a hollow core that looked wooden, and bamboo is very close to that.

569
00:37:22,000 --> 00:37:24,000
So we're gonna try it out.

570
00:37:24,000 --> 00:37:27,000
Did Robin Hood use some movie magic?

571
00:37:28,000 --> 00:37:30,000
Let's take a closer look.

572
00:37:30,000 --> 00:37:38,000
Slowed right down, the target arrow sure does look hollow, and the rings on the edge are very similar to bamboo.

573
00:37:40,000 --> 00:37:43,000
Of course, bamboo originates in Asia.

574
00:37:43,000 --> 00:37:52,000
Robin Hood did not fire arrows like this, but can the team split this completely unauthentic movie-inspired shaft?

575
00:38:01,000 --> 00:38:03,000
This is what I'm talking about.

576
00:38:03,000 --> 00:38:05,000
You are the man!

577
00:38:06,000 --> 00:38:07,000
Fire.

578
00:38:07,000 --> 00:38:14,000
They cheated, but got what they wanted, a not-to-tip split that looks nearly identical to that from the movie.

579
00:38:16,000 --> 00:38:20,000
And what's more, it took just one arrow to get it right.

580
00:38:21,000 --> 00:38:27,000
So, on splitting an arrow revisit, we followed all the viewers' advice. What was the result?

581
00:38:27,000 --> 00:38:34,000
We gave them what they asked for. We made our own arrows, we had a traditional longbow, we even brought in a skilled archer who hid it,

582
00:38:34,000 --> 00:38:36,000
and he couldn't split it.

583
00:38:36,000 --> 00:38:40,000
After we were at the range, and we saw how the bamboo split right down the center,

584
00:38:40,000 --> 00:38:46,000
and we saw how we couldn't get into the cedar arrows more than 10 inches, I think the movie used bamboo.

585
00:38:46,000 --> 00:38:49,000
And as we know, anything's possible in the movies.

586
00:38:49,000 --> 00:38:50,000
That's right.

587
00:38:50,000 --> 00:38:51,000
Is it busted?

588
00:38:51,000 --> 00:38:52,000
Still busted.

589
00:38:52,000 --> 00:38:53,000
Busted. Busted.

590
00:39:00,000 --> 00:39:01,000
Civil War Rocket.

591
00:39:01,000 --> 00:39:04,000
The Mythbusters are revisiting Confederate Rocket.

592
00:39:05,000 --> 00:39:06,000
Ignition!

593
00:39:09,000 --> 00:39:13,000
In that myth, their ludicrous launch exceeded all expectations.

594
00:39:19,000 --> 00:39:22,000
So far, the same can't be said of their revisit.

595
00:39:22,000 --> 00:39:26,000
Their first salami rocket was rather sorry for itself.

596
00:39:26,000 --> 00:39:28,000
But all is not lost.

597
00:39:29,000 --> 00:39:34,000
To try to get a little more altitude, the team is going to give it one more go,

598
00:39:34,000 --> 00:39:37,000
with a new nozzle that may better focus the thrust.

599
00:39:37,000 --> 00:39:39,000
And that's not the only change.

600
00:39:40,000 --> 00:39:47,000
You know, the main criticism we got for our first Confederate rocket launch was that we did not have sufficient camera coverage.

601
00:39:47,000 --> 00:39:51,000
People complained that we didn't cover the rocket's flight, and that we didn't have an onboard camera.

602
00:39:51,000 --> 00:39:56,000
You have to remember that this was an experimental rocket, and we had no idea that it was actually going to work.

603
00:39:56,000 --> 00:39:58,000
I thought it was going to blow up.

604
00:39:58,000 --> 00:40:03,000
Well, for those viewers that want to see some of that kind of fancy footage, here's some from Eric Gates.

605
00:40:05,000 --> 00:40:09,000
Eric Gates, rocket expert and cameraman.

606
00:40:09,000 --> 00:40:14,000
And luckily, Eric just happens to have brought his rocket camera with him.

607
00:40:14,000 --> 00:40:19,000
But will the new salami rocket reach an altitude as high as this?

608
00:40:21,000 --> 00:40:23,000
We got a Junkyard Rocket, man.

609
00:40:23,000 --> 00:40:28,000
This is fire number two with onboard camera.

610
00:40:29,000 --> 00:40:35,000
It's got all the gadgets, but will this salami rocket break the 20-foot record?

611
00:40:36,000 --> 00:40:39,000
In three, two, one.

612
00:40:43,000 --> 00:40:46,000
It didn't go even as far as the first one.

613
00:40:46,000 --> 00:40:50,000
But it went up! Hey! All right.

614
00:40:51,000 --> 00:40:56,000
On ignition, the nozzle blew out, so there was nothing to focus the salami thrust.

615
00:40:56,000 --> 00:41:01,000
And the onboard camera blew too, but it was mission accomplished.

616
00:41:03,000 --> 00:41:07,000
I'm actually not at all surprised that salami works really well as a rocket fuel.

617
00:41:07,000 --> 00:41:11,000
No doubt ours could be better. We need a little more refinement here and there.

618
00:41:11,000 --> 00:41:16,000
But the beauty of the hybrid rocket is that it'll burn just about any hydrocarbon,

619
00:41:16,000 --> 00:41:20,000
and it'll burn it aggressively enough to serve as a rocket fuel.

620
00:41:20,000 --> 00:41:25,000
So, you know, we could have gone to the moon with salami.

621
00:41:26,000 --> 00:41:31,000
The moon? That's only 240,000 miles to go.

622
00:41:31,000 --> 00:41:35,000
So, salami rocket is busted, plausible or confirmed?

623
00:41:35,000 --> 00:41:38,000
Hey, a flight's a flight. We got airborne, so it's confirmed.

624
00:41:38,000 --> 00:41:43,000
Salami does seem to make a pretty good rocket fuel, but I'm going to stick with paraffin.

625
00:41:43,000 --> 00:41:46,000
Okay. We're taking this back home.

626
00:41:55,000 --> 00:41:57,000
He's tired now.
