1
00:00:00,000 --> 00:00:07,000
Don't try what you're about to see at home.

2
00:00:30,000 --> 00:00:32,000
Here's some Mythbuster madness.

3
00:00:32,000 --> 00:00:34,000
Huge dramatic music.

4
00:00:34,000 --> 00:00:36,000
Then envious of the candy and soda success,

5
00:00:36,000 --> 00:00:43,000
they go all out to find their very own magic combo of homemade mayhem.

6
00:00:43,000 --> 00:00:45,000
And on top of all that,

7
00:00:45,000 --> 00:00:48,000
Carrie Grant and Tari take on the tall tale

8
00:00:48,000 --> 00:00:53,000
that a postage stamp can cause a helicopter to spiral out of control.

9
00:00:53,000 --> 00:00:54,000
Are we nuts?

10
00:00:54,000 --> 00:00:59,000
If we're wrong about this, we're gonna have a really bad day.

11
00:01:00,000 --> 00:01:02,000
Who are the Mythbusters?

12
00:01:02,000 --> 00:01:03,000
Adam Savage

13
00:01:03,000 --> 00:01:05,000
I'm making a rocket out of meat.

14
00:01:05,000 --> 00:01:07,000
And Jamie Heineman

15
00:01:07,000 --> 00:01:09,000
I'm so excited.

16
00:01:09,000 --> 00:01:13,000
Between them more than 30 years of special effects experience.

17
00:01:13,000 --> 00:01:15,000
That's what I'm talking about.

18
00:01:15,000 --> 00:01:16,000
Joining them,

19
00:01:16,000 --> 00:01:17,000
Carrie Byron

20
00:01:17,000 --> 00:01:18,000
I'm a piñata.

21
00:01:18,000 --> 00:01:20,000
Grant Imahara

22
00:01:20,000 --> 00:01:22,000
Don't say anything.

23
00:01:22,000 --> 00:01:23,000
And Tari Belleggi

24
00:01:23,000 --> 00:01:25,000
Oh yeah, totally.

25
00:01:25,000 --> 00:01:27,000
They don't just tell the myths.

26
00:01:28,000 --> 00:01:31,000
They put them to the test.

27
00:01:37,000 --> 00:01:41,000
First up, the Mythbusters are going to have a blast.

28
00:01:41,000 --> 00:01:45,000
Alright guys, I've got a fun little experiment for you to try out.

29
00:01:45,000 --> 00:01:48,000
I was just doing this photo shoot with FHM,

30
00:01:48,000 --> 00:01:51,000
and it seems to coincide with an internet phenomena

31
00:01:51,000 --> 00:01:53,000
of people taking two liter bottles of soda

32
00:01:53,000 --> 00:01:55,000
and dropping twoy candies into it

33
00:01:55,000 --> 00:01:57,000
for boom, big explosive.

34
00:01:57,000 --> 00:01:58,000
Oh yeah, I've seen that.

35
00:01:58,000 --> 00:01:59,000
It's all over the net.

36
00:01:59,000 --> 00:02:01,000
It creates some kind of geyser

37
00:02:01,000 --> 00:02:03,000
that comes out the end of the soda bottle, right?

38
00:02:03,000 --> 00:02:06,000
Yeah, and every time I've seen it on the web

39
00:02:06,000 --> 00:02:07,000
or on television,

40
00:02:07,000 --> 00:02:10,000
they've trot out an expert to tell us why it happens.

41
00:02:10,000 --> 00:02:13,000
And all of their explanations are amazingly different.

42
00:02:13,000 --> 00:02:15,000
None of them agree with each other.

43
00:02:15,000 --> 00:02:19,000
So we're not going to test whether or not this occurs.

44
00:02:19,000 --> 00:02:20,000
No, we know that it occurs.

45
00:02:20,000 --> 00:02:22,000
We're going to have to check out

46
00:02:22,000 --> 00:02:25,000
whether these various explanations are correct though.

47
00:02:25,000 --> 00:02:27,000
And which one is correct, if any?

48
00:02:27,000 --> 00:02:28,000
Okay.

49
00:02:28,000 --> 00:02:32,000
It's a craze that was kicked off by our very own bubbly Mythbuster.

50
00:02:32,000 --> 00:02:35,000
Add some Mentos to some Diet Coke,

51
00:02:35,000 --> 00:02:38,000
and you get a cascade of swell proportions.

52
00:02:41,000 --> 00:02:44,000
But it's these guys, the Epee Birds from Buckfield, Maine,

53
00:02:44,000 --> 00:02:48,000
that up the ante using 101 bottles of Diet Coke,

54
00:02:48,000 --> 00:02:50,000
523 Mentos,

55
00:02:50,000 --> 00:02:54,000
and the sort of choreography normally only seen in Vegas,

56
00:02:54,000 --> 00:02:57,000
they made the ultimate fizzy fountain.

57
00:02:57,000 --> 00:03:00,000
Apparently all I have to do is that,

58
00:03:00,000 --> 00:03:02,000
whoop, and drop them in.

59
00:03:02,000 --> 00:03:04,000
Are you ready?

60
00:03:04,000 --> 00:03:06,000
I've never tried this before.

61
00:03:08,000 --> 00:03:09,000
Wow!

62
00:03:13,000 --> 00:03:17,000
That was like 10 feet!

63
00:03:18,000 --> 00:03:20,000
The four Mentos are dropped in,

64
00:03:20,000 --> 00:03:23,000
and then, as reliably as all faithful,

65
00:03:23,000 --> 00:03:25,000
the guys are erupts.

66
00:03:25,000 --> 00:03:27,000
That is cool.

67
00:03:27,000 --> 00:03:30,000
I think we're going to have to try that a whole bunch more times.

68
00:03:30,000 --> 00:03:32,000
It's a ton of fun,

69
00:03:32,000 --> 00:03:37,000
but the Mythbuster's mission is to find out exactly what's going on inside that bottle.

70
00:03:37,000 --> 00:03:39,000
Hey, look at that!

71
00:03:39,000 --> 00:03:41,000
Well, amid the chaos,

72
00:03:41,000 --> 00:03:46,000
it's clear that this foamy fountain has something to do with the cola's fizziness.

73
00:03:46,000 --> 00:03:48,000
And to find out more,

74
00:03:48,000 --> 00:03:50,000
it's over to our resident fountain of knowledge.

75
00:03:50,000 --> 00:03:54,000
The gas component of this soda is CO2,

76
00:03:54,000 --> 00:03:58,000
and we want to know what role it plays in this cascading effect

77
00:03:58,000 --> 00:04:00,000
that we see when we drop these candies in.

78
00:04:00,000 --> 00:04:05,000
So, the one way that I know of to figure this out

79
00:04:05,000 --> 00:04:08,000
is to actually remove the gas,

80
00:04:08,000 --> 00:04:14,000
and we should be able to do that by just agitating the soda until it fills up this balloon.

81
00:04:14,000 --> 00:04:17,000
And then once we've removed all of the gas,

82
00:04:17,000 --> 00:04:20,000
if we drop the candy in and we don't get any reaction,

83
00:04:20,000 --> 00:04:22,000
we'll know that it was because of the gas.

84
00:04:22,000 --> 00:04:24,000
Let's see what the candy does now.

85
00:04:25,000 --> 00:04:27,000
Not a thing.

86
00:04:27,000 --> 00:04:28,000
Not a thing.

87
00:04:28,000 --> 00:04:30,000
No CO2, no foam.

88
00:04:30,000 --> 00:04:35,000
So, carbonation is the first crucial ingredient on the cascade checklist,

89
00:04:35,000 --> 00:04:39,000
but surely there's more to this Mentos Mayhem.

90
00:04:39,000 --> 00:04:40,000
What's up?

91
00:04:40,000 --> 00:04:46,000
Well, we need to determine what else other than CO2 is at play here.

92
00:04:46,000 --> 00:04:47,000
If anything.

93
00:04:47,000 --> 00:04:48,000
If anything.

94
00:04:48,000 --> 00:04:51,000
So, this is playing soda water,

95
00:04:51,000 --> 00:04:54,000
and all it's got in it other than water is CO2.

96
00:04:54,000 --> 00:04:55,000
Well, and this is the diet cola,

97
00:04:55,000 --> 00:04:57,000
and it's got the whole bunch of other stuff.

98
00:04:57,000 --> 00:04:59,000
So, if CO2 is the only factor,

99
00:04:59,000 --> 00:05:01,000
these two things should spur at the same height.

100
00:05:01,000 --> 00:05:02,000
Yeah.

101
00:05:02,000 --> 00:05:04,000
Alright, let's try them out.

102
00:05:05,000 --> 00:05:06,000
Ready?

103
00:05:06,000 --> 00:05:07,000
Two, one.

104
00:05:11,000 --> 00:05:13,000
Well, that's pretty clear.

105
00:05:13,000 --> 00:05:14,000
That's pretty clear.

106
00:05:14,000 --> 00:05:17,000
The diet cola, there's definitely something more going on

107
00:05:17,000 --> 00:05:19,000
than just the content of CO2 and the candy.

108
00:05:19,000 --> 00:05:23,000
Because the diet cola went like five or six times as high as the soda water.

109
00:05:23,000 --> 00:05:27,000
So, CO2 is not the only culprit in the cola cascade.

110
00:05:27,000 --> 00:05:29,000
The plot thickens.

111
00:05:33,000 --> 00:05:35,000
And now, Tari, Carrie and Grant

112
00:05:35,000 --> 00:05:38,000
are going to stamp their authority on another myth.

113
00:05:38,000 --> 00:05:41,000
We're hanging out in a hangar with a helicopter,

114
00:05:41,000 --> 00:05:44,000
a bunch of stamps in the Oakland Police Department.

115
00:05:44,000 --> 00:05:45,000
What are we doing here?

116
00:05:45,000 --> 00:05:48,000
Well, we actually just got this myth off our fan site,

117
00:05:48,000 --> 00:05:51,000
and what they say is that a simple postage stamp

118
00:05:51,000 --> 00:05:53,000
stuck on a rotary blade of a helicopter

119
00:05:53,000 --> 00:05:56,000
will unbalance the helicopter and cause it to crash.

120
00:05:58,000 --> 00:06:00,000
So, according to our wonderful fans,

121
00:06:00,000 --> 00:06:02,000
if you stick a regular postage stamp

122
00:06:02,000 --> 00:06:04,000
on the rotors of a helicopter,

123
00:06:04,000 --> 00:06:07,000
it can set off the finally balanced blade so much

124
00:06:07,000 --> 00:06:11,000
that the result is some airmail carnage.

125
00:06:13,000 --> 00:06:14,000
Sounds like a bunch of fun.

126
00:06:14,000 --> 00:06:16,000
We've got our stamps.

127
00:06:16,000 --> 00:06:18,000
We've got our helicopter. Let's go for it.

128
00:06:20,000 --> 00:06:22,000
I don't think they're going to let us use their chopper

129
00:06:22,000 --> 00:06:24,000
both for insurance and for safety reasons,

130
00:06:24,000 --> 00:06:27,000
until we can show them that it's not going to hurt their chopper.

131
00:06:27,000 --> 00:06:31,000
So, I think we should probably start with some small scale testing.

132
00:06:31,000 --> 00:06:32,000
These things aren't cheap.

133
00:06:32,000 --> 00:06:33,000
No.

134
00:06:34,000 --> 00:06:37,000
So, before risking cash and cash in this,

135
00:06:37,000 --> 00:06:41,000
the team is first going to wreak postal pandemonium

136
00:06:41,000 --> 00:06:43,000
on something a little cheaper.

137
00:06:43,000 --> 00:06:45,000
I'll take that one and that one.

138
00:06:45,000 --> 00:06:47,000
Give us one of everything.

139
00:06:47,000 --> 00:06:49,000
Hovering around the $2,000 mark,

140
00:06:49,000 --> 00:06:52,000
these remote control helis will be perfect

141
00:06:52,000 --> 00:06:54,000
to get this myth off the ground,

142
00:06:54,000 --> 00:06:57,000
provided that the team can learn how to fly them.

143
00:06:57,000 --> 00:06:59,000
How hard is it to fly these?

144
00:06:59,000 --> 00:07:01,000
We tell customers that you're guaranteed

145
00:07:01,000 --> 00:07:03,000
that you're going to crash.

146
00:07:03,000 --> 00:07:04,000
It's not.

147
00:07:04,000 --> 00:07:05,000
That's a good guarantee.

148
00:07:05,000 --> 00:07:06,000
Okay, great.

149
00:07:06,000 --> 00:07:09,000
Because crashing is guaranteed,

150
00:07:09,000 --> 00:07:11,000
they're going to hone their heli skills

151
00:07:11,000 --> 00:07:13,000
on this unbreakable trainer,

152
00:07:13,000 --> 00:07:15,000
which Paul makes look pretty easy.

153
00:07:18,000 --> 00:07:20,000
You are nimble with that thing.

154
00:07:20,000 --> 00:07:24,000
But unfortunately, the same can't be said for Grant.

155
00:07:25,000 --> 00:07:28,000
This heli's going belly up.

156
00:07:28,000 --> 00:07:30,000
Okay, give me another day and a half.

157
00:07:31,000 --> 00:07:33,000
Despite the hover bother,

158
00:07:33,000 --> 00:07:35,000
the team buys the trainer

159
00:07:35,000 --> 00:07:38,000
and a remote control version of the Oakland's Police Helicopter,

160
00:07:38,000 --> 00:07:42,000
which back at M5, Grant has to put together.

161
00:07:42,000 --> 00:07:46,000
This police chopper is an exact 1 7th scale model

162
00:07:46,000 --> 00:07:48,000
of its full-size counterpart.

163
00:07:48,000 --> 00:07:50,000
So to test the stamp myth in miniature,

164
00:07:50,000 --> 00:07:54,000
the team also needs some 1 7th scale stamps.

165
00:07:57,000 --> 00:07:59,000
Okay, what we're going to do right now,

166
00:07:59,000 --> 00:08:01,000
we have a scale and we're going to measure

167
00:08:01,000 --> 00:08:03,000
to see how much a postage stamp weighs.

168
00:08:03,000 --> 00:08:06,000
Because the whole myth is to see if, you know,

169
00:08:06,000 --> 00:08:09,000
the little bit of weight could unbalance the helicopter

170
00:08:09,000 --> 00:08:10,000
and cause it to crash.

171
00:08:10,000 --> 00:08:12,000
Our first saboteur.

172
00:08:12,000 --> 00:08:14,000
Yeah, this is the 45-cent stamp.

173
00:08:14,000 --> 00:08:16,000
We've got .15 grams.

174
00:08:16,000 --> 00:08:17,000
As well as the weigh-in,

175
00:08:17,000 --> 00:08:20,000
Carrie is also shrinking everything right down.

176
00:08:20,000 --> 00:08:24,000
This is about the size of 1 7th of this.

177
00:08:24,000 --> 00:08:27,000
So that'll be about the scaled version of the stamp

178
00:08:27,000 --> 00:08:29,000
that's going to go on our little helicopter.

179
00:08:29,000 --> 00:08:33,000
So now all they have to do is get the scale down chopper airborne.

180
00:08:33,000 --> 00:08:36,000
But that ain't going to be easy.

181
00:08:37,000 --> 00:08:41,000
Geez, this is a little harder than it looks.

182
00:08:41,000 --> 00:08:44,000
This is going to make small-scale experiments extremely hard

183
00:08:44,000 --> 00:08:47,000
if we can't even get the helicopter off the ground.

184
00:08:47,000 --> 00:08:48,000
Yeah.

185
00:08:48,000 --> 00:08:49,000
With Tori failing to fly,

186
00:08:49,000 --> 00:08:53,000
remote control expert Grant takes the reins.

187
00:08:53,000 --> 00:08:56,000
Look at the stance. I like the stance.

188
00:08:56,000 --> 00:08:59,000
But he's not accruing any flight time either.

189
00:08:59,000 --> 00:09:01,000
Mayday, mayday.

190
00:09:01,000 --> 00:09:04,000
With the model helicopter falling flat,

191
00:09:04,000 --> 00:09:07,000
this myth is struggling to even get off the ground.

192
00:09:08,000 --> 00:09:11,000
Later, the mythbusters trump the Cola Cascade

193
00:09:11,000 --> 00:09:14,000
with their very own household histrionics.

194
00:09:18,000 --> 00:09:22,000
But next, will there be airmail carnage with the heli stamp?

195
00:09:22,000 --> 00:09:24,000
I don't know if it's just my imagination,

196
00:09:24,000 --> 00:09:26,000
but it looks a little wobbly to me.

197
00:09:27,000 --> 00:09:31,000
This is the candy and soda sensation that's sweeping the nation.

198
00:09:31,000 --> 00:09:35,000
Inboxes across the world are gushing with these amazing

199
00:09:35,000 --> 00:09:38,000
choreographed fountains of froth.

200
00:09:40,000 --> 00:09:42,000
But Adam and Jamie are on a mission

201
00:09:42,000 --> 00:09:45,000
to determine the science behind the sizzle.

202
00:09:46,000 --> 00:09:48,000
Oh, that's a nice one. 10 feet.

203
00:09:48,000 --> 00:09:51,000
They've confirmed Diet Coke is the king of Cascades,

204
00:09:51,000 --> 00:09:55,000
and now Adam must find exactly which ingredients are at work.

205
00:09:55,000 --> 00:10:00,000
I've got Aspartame armed with the constituents of Diet Coke.

206
00:10:00,000 --> 00:10:02,000
How's he going to use them?

207
00:10:02,000 --> 00:10:04,000
The soda water is our test bed.

208
00:10:04,000 --> 00:10:06,000
It's our basic unit of measurement here.

209
00:10:06,000 --> 00:10:09,000
I will be adding each of these ingredients one at a time

210
00:10:09,000 --> 00:10:12,000
to individual bottles of this and trying it out with the candy

211
00:10:12,000 --> 00:10:16,000
and seeing if I get a more vigorous response than just the soda water alone.

212
00:10:16,000 --> 00:10:20,000
If and when I do, I may find out that it's chemical D

213
00:10:20,000 --> 00:10:22,000
that provides the most vigorous response,

214
00:10:22,000 --> 00:10:24,000
and we can say, oh, there's your culprit.

215
00:10:24,000 --> 00:10:28,000
That's the plan, and first up is A for Aspartame,

216
00:10:28,000 --> 00:10:30,000
Diet Coke's artificial sweetener.

217
00:10:31,000 --> 00:10:34,000
Adam makes up a solution of the sugar substitute,

218
00:10:34,000 --> 00:10:39,000
adds it to the soda water, and gets ready to drop in a mentos.

219
00:10:40,000 --> 00:10:42,000
Remember, in their earlier test,

220
00:10:42,000 --> 00:10:45,000
soda water plus mentos equal three inches.

221
00:10:46,000 --> 00:10:49,000
So what will happen with the sweetener added?

222
00:10:49,000 --> 00:10:55,000
Sweet. The sweetener's made the cascade 20 times higher.

223
00:10:55,000 --> 00:10:57,000
That's interesting.

224
00:10:57,000 --> 00:11:00,000
That's a much more vigorous reaction than the soda water alone.

225
00:11:00,000 --> 00:11:02,000
Aspartame is doing something to the water.

226
00:11:02,000 --> 00:11:05,000
But what about the other main ingredients?

227
00:11:05,000 --> 00:11:07,000
First, the acids.

228
00:11:07,000 --> 00:11:10,000
But neither the citric acid nor the phosphoric acid

229
00:11:10,000 --> 00:11:14,000
excite any alchemy, or for that matter, Adam.

230
00:11:15,000 --> 00:11:18,000
Total bupkus in terms of reaction.

231
00:11:18,000 --> 00:11:22,000
Then it's the preservative, potassium benzoate.

232
00:11:22,000 --> 00:11:25,000
That in and of itself is a little bit of a reaction.

233
00:11:25,000 --> 00:11:27,000
Let's see what happens when I add the candy.

234
00:11:28,000 --> 00:11:31,000
The preservative also enhances the cascade.

235
00:11:31,000 --> 00:11:34,000
It's almost an identical reaction to the Aspartame.

236
00:11:35,000 --> 00:11:37,000
Last up is the caffeine.

237
00:11:37,000 --> 00:11:40,000
This is a couple of tablespoons of caffeine in solution,

238
00:11:40,000 --> 00:11:42,000
pure powdered caffeine.

239
00:11:42,000 --> 00:11:44,000
This is probably enough to kill you.

240
00:11:44,000 --> 00:11:47,000
It's scary stuff when you start to increase the concentration.

241
00:11:49,000 --> 00:11:52,000
Again, the same kind of reaction.

242
00:11:52,000 --> 00:11:55,000
Caffeine, potassium benzoate, and Aspartame

243
00:11:55,000 --> 00:11:58,000
all had pretty much identical reactions.

244
00:11:58,000 --> 00:12:02,000
So Adam and Jamie have isolated the key active ingredients

245
00:12:02,000 --> 00:12:04,000
in the diet code.

246
00:12:04,000 --> 00:12:06,000
Next, they're going to find out what the mentors

247
00:12:06,000 --> 00:12:08,000
bring to the cascade carnival.

248
00:12:08,000 --> 00:12:12,000
Cary Grant and Tori are investigating a copter calamity.

249
00:12:12,000 --> 00:12:16,000
Can posting a posted stamp on the precisely engineered

250
00:12:16,000 --> 00:12:18,000
rotor blades do this?

251
00:12:20,000 --> 00:12:22,000
This is a very expensive model,

252
00:12:22,000 --> 00:12:26,000
and people generally crash these the first time they fly them.

253
00:12:26,000 --> 00:12:28,000
And we actually want to get some good data from it.

254
00:12:28,000 --> 00:12:30,000
So we are going to do a little bit of a test

255
00:12:30,000 --> 00:12:32,000
and we're going to do a little bit of a test

256
00:12:32,000 --> 00:12:34,000
and we're going to do a little bit of a test

257
00:12:34,000 --> 00:12:36,000
and we're going to do a little bit of a test

258
00:12:36,000 --> 00:12:38,000
and we're going to get the data from it.

259
00:12:38,000 --> 00:12:40,000
So we are going to start these tests

260
00:12:40,000 --> 00:12:42,000
having this helicopter completely tethered down.

261
00:12:42,000 --> 00:12:47,000
We've securely fastened the helicopter to the table.

262
00:12:47,000 --> 00:12:51,000
And the reason is that we want to actually see the blade deflection.

263
00:12:51,000 --> 00:12:53,000
We don't want the helicopter actually getting lift

264
00:12:53,000 --> 00:12:55,000
and moving all over the place.

265
00:12:55,000 --> 00:12:57,000
What we're interested in at this point

266
00:12:57,000 --> 00:13:00,000
is looking at how far that posted stamp

267
00:13:00,000 --> 00:13:03,000
will deflect the blade and what effect that has.

268
00:13:03,000 --> 00:13:07,000
And to see this, they've put a marked scale behind the chopper

269
00:13:07,000 --> 00:13:09,000
which when coupled with the high speed camera

270
00:13:09,000 --> 00:13:13,000
will show them precisely how much wobble there is in the rotors.

271
00:13:13,000 --> 00:13:15,000
Throttle.

272
00:13:15,000 --> 00:13:17,000
Ready? Go!

273
00:13:20,000 --> 00:13:23,000
Okay, so this will be our baseline test.

274
00:13:23,000 --> 00:13:27,000
Just stock blades, no additional weight.

275
00:13:28,000 --> 00:13:30,000
Grant cranks the speed up to level 5

276
00:13:30,000 --> 00:13:33,000
and then cues the high speed camera.

277
00:13:33,000 --> 00:13:35,000
We're at speed, ready to capture.

278
00:13:35,000 --> 00:13:38,000
And sure enough, without any added weight

279
00:13:38,000 --> 00:13:40,000
the heli blades are in perfect balance.

280
00:13:40,000 --> 00:13:44,000
They're rotating exactly on the level of the blue line in the background.

281
00:13:44,000 --> 00:13:46,000
We just finished our baseline test.

282
00:13:46,000 --> 00:13:49,000
We saw that our blades are totally balanced.

283
00:13:49,000 --> 00:13:52,000
Now what we're going to do is put on a 1.7 scale

284
00:13:52,000 --> 00:13:54,000
posted stamp and see what happens.

285
00:13:54,000 --> 00:13:58,000
The stamp, like the model heli, is 1.7 normal size.

286
00:13:58,000 --> 00:14:01,000
That's just 0.02 grams.

287
00:14:01,000 --> 00:14:05,000
Will it really be enough to cause the chopper to become a dropper?

288
00:14:05,000 --> 00:14:07,000
Looks pretty good.

289
00:14:07,000 --> 00:14:10,000
The stamp doesn't look like it's having any effect.

290
00:14:10,000 --> 00:14:12,000
And the high speed agrees.

291
00:14:12,000 --> 00:14:16,000
With the stamp, the blades are just as balanced as they were without it.

292
00:14:16,000 --> 00:14:19,000
So what does this mean for the myth?

293
00:14:19,000 --> 00:14:23,000
Based on our scale test with a scale posted stamp

294
00:14:23,000 --> 00:14:26,000
and the closest thing that we can get in scale

295
00:14:26,000 --> 00:14:30,000
to a real helicopter, this myth is looking busted.

296
00:14:30,000 --> 00:14:35,000
Later, Tori and Carrie put their lives on the line in a real chopper.

297
00:14:35,000 --> 00:14:37,000
Are we nuts?

298
00:14:37,000 --> 00:14:40,000
We got stamps on the top rotor and the tail rotor.

299
00:14:40,000 --> 00:14:45,000
But next, Adam and Jamie go nuclear with nucleation.

300
00:14:45,000 --> 00:14:47,000
How high did that go?

301
00:14:49,000 --> 00:14:53,000
Adam and Jamie are trying to figure out the theory behind the chaos

302
00:14:53,000 --> 00:14:56,000
when diet coke and Mentos meet.

303
00:14:56,000 --> 00:14:59,000
Our super sleuths have found the ingredients in the soda

304
00:14:59,000 --> 00:15:02,000
that cause the fountain to fraud.

305
00:15:02,000 --> 00:15:05,000
But what do the Mentos bring to the party?

306
00:15:05,000 --> 00:15:08,000
Adam has checked out the mint Mentos ingredients

307
00:15:08,000 --> 00:15:12,000
and he's narrowed down a suspect or two that may be of interest.

308
00:15:12,000 --> 00:15:15,000
Gum Arabic and gelatin.

309
00:15:15,000 --> 00:15:21,000
Let's pour in this gum Arabic and see if it makes the water want to release more CO2 faster.

310
00:15:22,000 --> 00:15:24,000
And so it does.

311
00:15:24,000 --> 00:15:27,000
Look at that. I'd call that a reaction.

312
00:15:27,000 --> 00:15:32,000
Sure enough, both of the ingredients cause bubbles to burst forth.

313
00:15:32,000 --> 00:15:36,000
But there must be more to the Mentos magic than that.

314
00:15:36,000 --> 00:15:39,000
The most common theory about what's going on in this reaction

315
00:15:39,000 --> 00:15:42,000
between the candy and the soda is what's called nucleation.

316
00:15:42,000 --> 00:15:46,000
Basically, the idea is that the surface of the candy

317
00:15:46,000 --> 00:15:49,000
is covered with microscopic pits

318
00:15:49,000 --> 00:15:52,000
and lots of more surface area than you can actually see.

319
00:15:52,000 --> 00:15:56,000
And each little pit, each little corner provides what's called a nucleation site

320
00:15:56,000 --> 00:16:00,000
or a place where a carbon dioxide bubble can form and escape.

321
00:16:00,000 --> 00:16:04,000
Look at a Mentos close up and it's like the surface of the moon

322
00:16:04,000 --> 00:16:07,000
and that might be the candy key.

323
00:16:07,000 --> 00:16:11,000
Drop one in cola and every tiny crater provides a site

324
00:16:11,000 --> 00:16:14,000
where a CO2 molecule can change to gas.

325
00:16:14,000 --> 00:16:19,000
Because Mentos are so pitted, the theory is that millions of CO2 bubbles

326
00:16:19,000 --> 00:16:22,000
are formed in a very short space of time.

327
00:16:22,000 --> 00:16:28,000
And because the candy sinks and this rapid release of gas happens at the bottom of the cola,

328
00:16:28,000 --> 00:16:31,000
you get that famous fountain.

329
00:16:31,000 --> 00:16:36,000
To test this nucleation theory, they're going to start with a control.

330
00:16:36,000 --> 00:16:39,000
One regular mint Mentos dropped in soda water.

331
00:16:39,000 --> 00:16:43,000
And sure enough, it gets the bubbly party started.

332
00:16:43,000 --> 00:16:45,000
Now to do a comparison.

333
00:16:45,000 --> 00:16:48,000
These two candies are made by the same manufacturer

334
00:16:48,000 --> 00:16:52,000
and as far as I'm aware, even using the same process.

335
00:16:52,000 --> 00:16:56,000
But the colored version of this actually has a glazing over it.

336
00:16:56,000 --> 00:17:01,000
It's a wax coating or a sealer that inhibits the nucleation process

337
00:17:01,000 --> 00:17:04,000
that the other one achieves quite readily.

338
00:17:04,000 --> 00:17:07,000
The shiniest surface should lower the nucleation sites,

339
00:17:07,000 --> 00:17:10,000
meaning less of an immediate eruption.

340
00:17:11,000 --> 00:17:15,000
That's not doing anything more than the wall of the plastic bottle itself.

341
00:17:15,000 --> 00:17:20,000
Sure enough, with the smooth Mentos, there ain't no whiz with the fizz,

342
00:17:20,000 --> 00:17:25,000
proving that nucleation is the prime mover on the active ingredient checklist.

343
00:17:25,000 --> 00:17:31,000
And with all the culprits exposed, the mythbusters can say they finally cracked the case

344
00:17:31,000 --> 00:17:33,000
of the candy and cola cascade.

345
00:17:33,000 --> 00:17:36,000
So you guys come up with anything? What causes the reaction?

346
00:17:36,000 --> 00:17:41,000
Yep, we sure did. And we also busted everything that we've seen in the media

347
00:17:41,000 --> 00:17:47,000
because not a single one of them came up with a complete explanation of what is going on with the soda.

348
00:17:47,000 --> 00:17:50,000
They all had a piece of the puzzle.

349
00:17:50,000 --> 00:17:54,000
In fact, it turns out that this combination of most of the explanations we've read.

350
00:17:54,000 --> 00:18:00,000
The primary initiator of the reaction is nucleation, the candy helping bubbles to form in the soda.

351
00:18:00,000 --> 00:18:04,000
But it turns out that the ingredients that make up the candy match perfectly

352
00:18:04,000 --> 00:18:07,000
are the ingredients that make up the soda to create what's called a cascade effect

353
00:18:07,000 --> 00:18:11,000
whereby the soda wants to let go of all of its CO2 instantaneously.

354
00:18:11,000 --> 00:18:13,000
And that's what makes the explosion happen.

355
00:18:14,000 --> 00:18:16,000
But the fun ain't done yet.

356
00:18:16,000 --> 00:18:19,000
In an attempt to put the power of the cascade to work,

357
00:18:19,000 --> 00:18:22,000
Jamie and Adam build a cola concept rocket.

358
00:18:23,000 --> 00:18:24,000
Here's to a successful launch.

359
00:18:24,000 --> 00:18:25,000
You got it.

360
00:18:26,000 --> 00:18:32,000
The rotor blades of a helicopter, even a scaled down version,

361
00:18:32,000 --> 00:18:37,000
are so precisely balanced that apparently the weight of a single postage stamp

362
00:18:37,000 --> 00:18:41,000
is enough to render them catastrophically unstable.

363
00:18:43,000 --> 00:18:46,000
Tori, Carrie and Grant have been small scale testing.

364
00:18:46,000 --> 00:18:49,000
And at least on this helicopter, the myth is busted.

365
00:18:49,000 --> 00:18:53,000
So now they want to know what it does take to get that down.

366
00:18:53,000 --> 00:18:57,000
They want to know what it does take to get that lethal instability.

367
00:18:59,000 --> 00:19:00,000
I say we destroy it.

368
00:19:00,000 --> 00:19:02,000
This is why we can't have anything nice.

369
00:19:02,000 --> 00:19:09,000
And surely the weight of 8,000 stamps will be enough to wreak the helicopter havoc thereafter.

370
00:19:14,000 --> 00:19:15,000
Right there!

371
00:19:15,000 --> 00:19:18,000
Right there! That was it!

372
00:19:18,000 --> 00:19:20,000
That's what we're looking for.

373
00:19:20,000 --> 00:19:22,000
Ain't that the truth?

374
00:19:22,000 --> 00:19:25,000
It was 8,000 more stamps than the myth.

375
00:19:25,000 --> 00:19:29,000
But at last the guys get the chopper disaster they wanted.

376
00:19:29,000 --> 00:19:32,000
But this myth is far from over.

377
00:19:32,000 --> 00:19:37,000
With the small scale copter in pieces, it's time to return to the hangar

378
00:19:37,000 --> 00:19:40,000
to test the myth on the real deal.

379
00:19:40,000 --> 00:19:45,000
So Rick, have you ever heard the myth that a postage stamp is enough to unbalance a helicopter,

380
00:19:45,000 --> 00:19:47,000
potentially crash it?

381
00:19:47,000 --> 00:19:49,000
I have not heard that myth.

382
00:19:49,000 --> 00:19:55,000
I do know that the blade system is very sensitive to items on the rotors,

383
00:19:55,000 --> 00:19:59,000
which can include balloons, dust, paint.

384
00:19:59,000 --> 00:20:04,000
So it can affect the flight characteristics of the aircraft.

385
00:20:04,000 --> 00:20:10,000
If mere dust can unbalance this chopper, then a postage stamp might have an effect after all.

386
00:20:10,000 --> 00:20:15,000
To put this to the test, Flight Engineer Chad has rigged a series of sensors

387
00:20:15,000 --> 00:20:19,000
that can detect the tiniest changes in the balance of the blades.

388
00:20:19,000 --> 00:20:21,000
What are the sensors telling you?

389
00:20:21,000 --> 00:20:24,000
This up here is called a velocimeter.

390
00:20:24,000 --> 00:20:29,000
It's in a lateral position, so it's going to measure vibrations laterally.

391
00:20:29,000 --> 00:20:32,000
If the main rotor mass is doing this, it's going to feel this lateral vibration.

392
00:20:32,000 --> 00:20:35,000
And that's because of some imbalance in the blades.

393
00:20:35,000 --> 00:20:36,000
Correct.

394
00:20:36,000 --> 00:20:39,000
This is really the final test.

395
00:20:39,000 --> 00:20:41,000
You can't be having a real helicopter.

396
00:20:41,000 --> 00:20:45,000
What we're going to do is take a postage stamp and put it on the rotor blade

397
00:20:45,000 --> 00:20:52,000
and see if that is enough to send it out of balance and possibly cause a catastrophic crash.

398
00:20:52,000 --> 00:20:59,000
Still to come, Adam and Jamie shoot for the moon as they build a rocket powered by Diet Coke and Mentos.

399
00:20:59,000 --> 00:21:00,000
Here's to a successful launch.

400
00:21:00,000 --> 00:21:01,000
You got it.

401
00:21:01,000 --> 00:21:02,000
But next...

402
00:21:02,000 --> 00:21:04,000
Coming up on Midbock Yard!

403
00:21:04,000 --> 00:21:05,000
Get a postage stamp!

404
00:21:05,000 --> 00:21:07,000
Take out a helicopter!

405
00:21:08,000 --> 00:21:11,000
Don't try what you're about to see at home.

406
00:21:15,000 --> 00:21:16,000
I'm going to try one of these.

407
00:21:16,000 --> 00:21:20,000
Adam and Jamie have been conjuring up some Diet Coke and Mentos magic.

408
00:21:20,000 --> 00:21:22,000
Three, two, one.

409
00:21:23,000 --> 00:21:24,000
Wow!

410
00:21:24,000 --> 00:21:29,000
They've carefully worked out exactly why these two products go ballistic.

411
00:21:29,000 --> 00:21:32,000
But now they want to launch onto a whole new level.

412
00:21:32,000 --> 00:21:35,000
You know, based on everything I'm seeing with what we've done so far,

413
00:21:35,000 --> 00:21:39,000
I think we could take this a step further and try and make a rocket out of this reaction.

414
00:21:39,000 --> 00:21:41,000
Rockets are always fun. Let's do it.

415
00:21:41,000 --> 00:21:44,000
Here goes big boom, simple rocket!

416
00:21:44,000 --> 00:21:48,000
Rockets and mythbusters go together like pizza and pepperoni.

417
00:21:48,000 --> 00:21:49,000
Ignition!

418
00:21:49,000 --> 00:21:51,000
The Confederate rocket was a blast.

419
00:21:52,000 --> 00:21:55,000
And the Salami missile was a sizzler.

420
00:21:55,000 --> 00:22:00,000
But now their challenge is to convert an upward fountain into downward thrust

421
00:22:00,000 --> 00:22:05,000
with a rocket to build and nothing but Diet Coke, Mentos and a bunch of plumbing parts,

422
00:22:05,000 --> 00:22:07,000
the boys are in their element.

423
00:22:07,000 --> 00:22:12,000
So we've designed this rocket to take full advantage of this cascading effect.

424
00:22:12,000 --> 00:22:16,000
All of this energy being transmitted out of these bottles

425
00:22:16,000 --> 00:22:20,000
and straight down is what we're looking for with a very simple lightweight device.

426
00:22:20,000 --> 00:22:21,000
Dead simple.

427
00:22:21,000 --> 00:22:27,000
And as Jamie will demonstrate for us, the PVC tubing redirects the cola cascade

428
00:22:27,000 --> 00:22:30,000
from four bottles down through a central pipe.

429
00:22:33,000 --> 00:22:34,000
It all comes out there.

430
00:22:34,000 --> 00:22:39,000
But the clever part is a set of magnets holding the Mentos in the pipes

431
00:22:39,000 --> 00:22:41,000
until Adam and Jamie are ready for launch.

432
00:22:41,000 --> 00:22:46,000
And before you can say, National Aeronautics and Space Administration,

433
00:22:46,000 --> 00:22:48,000
it's T-minus five seconds.

434
00:22:48,000 --> 00:22:49,000
Just a successful launch.

435
00:22:49,000 --> 00:22:50,000
You got it.

436
00:22:50,000 --> 00:22:55,000
And three, two, one, fire!

437
00:22:55,000 --> 00:22:56,000
One.

438
00:23:00,000 --> 00:23:03,000
At Houston, we have a problem.

439
00:23:07,000 --> 00:23:09,000
That's not enough for a rocket.

440
00:23:09,000 --> 00:23:15,000
Unfortunately, there are leaks and the cola cascade doesn't produce enough thrust

441
00:23:15,000 --> 00:23:19,000
to lift the weight of the piping and four bottles of cola.

442
00:23:19,000 --> 00:23:21,000
So it's back to the drawing board.

443
00:23:22,000 --> 00:23:25,000
And while Jamie goes to work lightning the load,

444
00:23:25,000 --> 00:23:30,000
Adam, for reasons known only to himself, puts a bottle of Coke on the lathe.

445
00:23:30,000 --> 00:23:33,000
No prizes for guessing what happens next.

446
00:23:38,000 --> 00:23:41,000
Then that could happen, for instance.

447
00:23:43,000 --> 00:23:46,000
I'm thinking he won't want to tell Jamie about this one.

448
00:23:46,000 --> 00:23:50,000
The cola probably isn't one of the recommended lubricants for a lathe.

449
00:23:51,000 --> 00:23:52,000
Don't tell Jamie.

450
00:23:52,000 --> 00:23:55,000
Okay, this is a secret between us.

451
00:23:56,000 --> 00:24:01,000
Luckily for Adam, Jamie's been busy working on a nozzle for a sleeker one-bottle rocket.

452
00:24:01,000 --> 00:24:03,000
And now he's ready for a test.

453
00:24:04,000 --> 00:24:05,000
Okay, let's go for it.

454
00:24:05,000 --> 00:24:06,000
Here we go.

455
00:24:06,000 --> 00:24:08,000
Three, two, one.

456
00:24:12,000 --> 00:24:13,000
What are you smiling about?

457
00:24:13,000 --> 00:24:15,000
It's another launch failure.

458
00:24:15,000 --> 00:24:18,000
But the mythbusters aren't going to give up without a fight.

459
00:24:18,000 --> 00:24:19,000
Okay, ready?

460
00:24:19,000 --> 00:24:20,000
Everybody set?

461
00:24:20,000 --> 00:24:23,000
Three, two, one.

462
00:24:26,000 --> 00:24:33,000
With lift off falling flat, again, it looks as if the cola concept rocket has Adam and Jamie beaten.

463
00:24:33,000 --> 00:24:36,000
And desperation is setting in.

464
00:24:36,000 --> 00:24:44,000
They've been unable to overcome the fact that there's not enough thrust from the cola cascade

465
00:24:44,000 --> 00:24:47,000
to get the weight of the bottle and soda airborne.

466
00:24:47,000 --> 00:24:50,000
And Adam, for one, isn't taking defeat too well.

467
00:24:50,000 --> 00:24:55,000
It's time to change course before he completely loses the plot.

468
00:24:59,000 --> 00:25:00,000
Rocket's a failure.

469
00:25:01,000 --> 00:25:02,000
Let's go for height.

470
00:25:03,000 --> 00:25:09,000
So the next chapter in this crazy cascade escapade is a height challenge.

471
00:25:09,000 --> 00:25:15,000
Since Carrie kicked it all off and these guys, the EP birds, raised the stakes,

472
00:25:15,000 --> 00:25:19,000
the internet has been a buzz with Diet Coke and Mentos Mania.

473
00:25:19,000 --> 00:25:23,000
There's even an unofficial spout record of 18 feet.

474
00:25:23,000 --> 00:25:27,000
In an attempt to top the record, Adam and Jamie are going head to head.

475
00:25:28,000 --> 00:25:29,000
I hate competitions.

476
00:25:30,000 --> 00:25:32,000
Yeah, when you lose.

477
00:25:33,000 --> 00:25:37,000
Adam's first with his attempted spurt into the record books

478
00:25:37,000 --> 00:25:42,000
and to increase the pressure of the fountain's flow, he's making a nozzle.

479
00:25:42,000 --> 00:25:46,000
Well, with a couple of extra minutes and a nice lathe and some aluminum,

480
00:25:46,000 --> 00:25:48,000
I did what any poi would make.

481
00:25:49,000 --> 00:25:52,000
What am I allowed to call it? A plasma sword?

482
00:25:52,000 --> 00:25:58,000
Except instead of a limited beam of pure plasma, it's soda.

483
00:26:00,000 --> 00:26:01,000
Yeah.

484
00:26:02,000 --> 00:26:05,000
Not so much Yoda, but soda.

485
00:26:07,000 --> 00:26:12,000
Outside and Adam is all set to use the force of the cola cascade

486
00:26:12,000 --> 00:26:15,000
to beat the world record of 18 feet.

487
00:26:15,000 --> 00:26:17,000
Three, two, one.

488
00:26:18,000 --> 00:26:19,000
Hey!

489
00:26:19,000 --> 00:26:20,000
23 feet.

490
00:26:20,000 --> 00:26:22,000
It's a home run to start.

491
00:26:22,000 --> 00:26:26,000
Next, Jamie steps up to the plate reluctantly.

492
00:26:26,000 --> 00:26:29,000
They keep trying to get me to compete and I know I don't like it.

493
00:26:29,000 --> 00:26:34,000
Like Adam, Jamie simply uses a nozzle to give his spout more clout.

494
00:26:34,000 --> 00:26:38,000
The only problem I see with this thing is that I've got to get it on there really quickly

495
00:26:38,000 --> 00:26:41,000
or I'm going to get sprayed along with everybody else around here.

496
00:26:41,000 --> 00:26:43,000
So that's the trick.

497
00:26:43,000 --> 00:26:48,000
I've got to kind of like have three hands to operate this thing.

498
00:26:48,000 --> 00:26:52,000
That was sort of in this fire. The tube didn't load it straight down.

499
00:26:52,000 --> 00:26:58,000
Not a great start from the beret one, but a reload later, our mustachioed friend is back.

500
00:27:06,000 --> 00:27:10,000
Well, there you go. How high did that go?

501
00:27:10,000 --> 00:27:18,000
23 feet. It's an honorable draw, but the adrenaline of the competition has clearly gone to Jamie's head.

502
00:27:18,000 --> 00:27:25,000
With a mouthful of Mentos and Cola, it's not so much a gassy geyser as a gassy geyser.

503
00:27:29,000 --> 00:27:34,000
It's probably best that you don't try this at home.

504
00:27:37,000 --> 00:27:39,000
I don't want to see me do it again.

505
00:27:39,000 --> 00:27:50,000
Next, and the mythbusters are going to join forces and get some real hide on this puppy.

506
00:27:50,000 --> 00:27:55,000
And they must be confident because they extend the scale to 30 feet.

507
00:27:55,000 --> 00:27:58,000
And three, two, one.

508
00:27:59,000 --> 00:28:02,000
Oh my God.

509
00:28:02,000 --> 00:28:13,000
I actually could have held it. It blew it out of my hands for a second, so I think I can probably get another foot or two.

510
00:28:13,000 --> 00:28:15,000
You hit 29 feet.

511
00:28:15,000 --> 00:28:18,000
Well, I could probably make it 30 if you want to have another go.

512
00:28:18,000 --> 00:28:20,000
Another go? You betcha.

513
00:28:20,000 --> 00:28:22,000
Two, one.

514
00:28:22,000 --> 00:28:24,000
Oh! Two!

515
00:28:24,000 --> 00:28:34,000
They try various combinations of candies, salt, and the other enhancers they've unearthed over the course of their investigation.

516
00:28:34,000 --> 00:28:41,000
Before they get everything just right with Nucleation's sight-rich rock salt.

517
00:28:41,000 --> 00:28:43,000
Alright, we're ready up here.

518
00:28:48,000 --> 00:28:49,000
Dude!

519
00:28:49,000 --> 00:28:53,000
That went a full four feet above the meter.

520
00:28:53,000 --> 00:28:57,000
31, 34 feet, dude.

521
00:28:57,000 --> 00:28:59,000
That is not shabby.

522
00:28:59,000 --> 00:29:03,000
34 feet. It's the new benchmark to beat.

523
00:29:03,000 --> 00:29:05,000
Let's call it a day.

524
00:29:05,000 --> 00:29:06,000
Alright.

525
00:29:06,000 --> 00:29:08,000
I think we've set a fine, high watermark.

526
00:29:08,000 --> 00:29:10,000
It's all with salt.

527
00:29:10,000 --> 00:29:19,000
Back with the Helly's Angels, and the team has posted a stamp on the blades of this chopper.

528
00:29:19,000 --> 00:29:25,000
And they're about to find out if it's enough to catastrophically unbalance the rotors.

529
00:29:25,000 --> 00:29:30,000
But with the Helly hovering happily, this myth is sinking fast.

530
00:29:30,000 --> 00:29:33,000
I think we might be busted here.

531
00:29:33,000 --> 00:29:36,000
The chopper has survived intact.

532
00:29:36,000 --> 00:29:39,000
So, did the stamp make any difference at all?

533
00:29:39,000 --> 00:29:42,000
So, Chad, what did the computer come up with?

534
00:29:42,000 --> 00:29:55,000
Well, with our first flight without the poster stamp applied, with my measurements, our hover lateral, which is the side-to-side motion, measured a 0.173 inches per second, or IPS.

535
00:29:55,000 --> 00:29:57,000
So that's no stamp.

536
00:29:57,000 --> 00:29:58,000
That is no stamp.

537
00:29:58,000 --> 00:29:59,000
Okay.

538
00:29:59,000 --> 00:30:04,000
With the application of the stamp, hover lateral was a 0.174.

539
00:30:04,000 --> 00:30:12,000
So it only changed 1,000 of an IPS, which is actually minuscule.

540
00:30:12,000 --> 00:30:14,000
The stamp did next to nothing.

541
00:30:14,000 --> 00:30:17,000
It's looking like this myth should be returned to sender.

542
00:30:17,000 --> 00:30:21,000
But the team do want to try one last thing.

543
00:30:21,000 --> 00:30:30,000
Now, for those of you out there who are helicopter enthusiasts, I know you've been thinking all through the show, they're only concentrating on the main rotor.

544
00:30:30,000 --> 00:30:31,000
What about the tail boom?

545
00:30:31,000 --> 00:30:33,000
Well, today we're going to try the tail boom too.

546
00:30:33,000 --> 00:30:39,000
It's the twist in the tail, one stamp on the main rotor, and now one on the back one too.

547
00:30:39,000 --> 00:30:41,000
And there's no hover test for this one.

548
00:30:41,000 --> 00:30:44,000
Instead, the team is going for broke.

549
00:30:44,000 --> 00:30:45,000
Are we nuts?

550
00:30:45,000 --> 00:30:49,000
We got stamps on the top rotor and the tail rotor.

551
00:30:49,000 --> 00:30:55,000
Here's the thing, if we're wrong about this, we're going to have a really bad day.

552
00:30:55,000 --> 00:30:58,000
August 1, Roger, clear for takeoff on the go.

553
00:30:58,000 --> 00:31:01,000
They're up and away, and it's so far so good.

554
00:31:01,000 --> 00:31:08,000
Even with stamps on the main rotor and the tail boom, the chopper's flying straight as an arrow.

555
00:31:08,000 --> 00:31:09,000
Wait, are we going back?

556
00:31:09,000 --> 00:31:10,000
Yeah.

557
00:31:10,000 --> 00:31:12,000
I'm ready to go back.

558
00:31:16,000 --> 00:31:19,000
Oh, it's going to go for the slide right in.

559
00:31:19,000 --> 00:31:21,000
That is how you park it.

560
00:31:21,000 --> 00:31:22,000
Touchdown.

561
00:31:22,000 --> 00:31:29,000
The team is back in one piece, which means it's time to wrap up this postal caribou.

562
00:31:29,000 --> 00:31:32,000
Okay, Rick, well, we've been out in your helicopter today.

563
00:31:32,000 --> 00:31:34,000
We've run a bunch of tests.

564
00:31:34,000 --> 00:31:36,000
Post your stamp on a helicopter blade.

565
00:31:36,000 --> 00:31:37,000
What do you think?

566
00:31:37,000 --> 00:31:38,000
It had no effect.

567
00:31:38,000 --> 00:31:41,000
I felt no appreciable difference.

568
00:31:41,000 --> 00:31:42,000
Definitely busted.

569
00:31:42,000 --> 00:31:43,000
Definitely busted.

570
00:31:43,000 --> 00:31:48,000
But viewers keep sending in those stories, because that was a fun one.

571
00:31:48,000 --> 00:31:52,000
Coming right up, bubble, bubble, toil and trouble.

572
00:31:52,000 --> 00:31:58,000
Adam and Jamie concoct a witch's brew as they search for the next Diet Coke conventos phenomenon.

573
00:31:58,000 --> 00:32:01,000
That was like the beast dying at the end of the movie.

574
00:32:04,000 --> 00:32:06,000
So what do you want to do now?

575
00:32:06,000 --> 00:32:10,000
Well, I don't think we're done with candy and soda by a long shot.

576
00:32:10,000 --> 00:32:12,000
I mean, this thing is positively viral.

577
00:32:12,000 --> 00:32:14,000
It's everywhere.

578
00:32:14,000 --> 00:32:19,000
I think that what we could add to this is by looking for the next big thing.

579
00:32:19,000 --> 00:32:27,000
Well, I've got a ton of stuff that I get every day on email from people about all sorts of things that they can do with crap they've got laying around their house.

580
00:32:27,000 --> 00:32:28,000
So do I.

581
00:32:31,000 --> 00:32:39,000
So Adam and Jamie have got explosion envy and to soothe their egos, they're going to weave some homemade magic of their own.

582
00:32:39,000 --> 00:32:47,000
First out of the blocks is Adam and he's intending to set the worldwide Web of Light with a towering inferno of soapy water.

583
00:32:47,000 --> 00:32:55,000
We're trying something an old friend of mine gave me, which is that if you bubble methane up through soapy water,

584
00:32:55,000 --> 00:32:59,000
you'll end up with a column of bubbles because the methane is lighter than air.

585
00:32:59,000 --> 00:33:02,000
It helps lift the column and keep it stable.

586
00:33:02,000 --> 00:33:06,000
And then that column gets a certain height, however high you want it, you can light it.

587
00:33:06,000 --> 00:33:09,000
The whole thing goes, whoo, in the flame.

588
00:33:09,000 --> 00:33:14,000
And with a garden sprinkler on the end of a methane hose in a bucket of foamy water,

589
00:33:14,000 --> 00:33:18,000
it's not long before he has his very own bust of bubbles.

590
00:33:18,000 --> 00:33:22,000
I've been a bubble sculptor for about 20 years.

591
00:33:22,000 --> 00:33:27,000
The bubbles are a very fine way to sculpt the real world.

592
00:33:27,000 --> 00:33:34,000
Their first attempt is a little lopsided, but Adam is poised to feed the fire of his pyromania.

593
00:33:41,000 --> 00:33:44,000
That is so cool. It's water and it's burning.

594
00:33:44,000 --> 00:33:46,000
And now it's gone.

595
00:33:46,000 --> 00:33:50,000
Second time around and for Jamie and Adam, it's onwards and upwards.

596
00:33:50,000 --> 00:33:57,000
The bubbles are sticking together nicely and the lighter than air methane is pulling the flammable column skywards.

597
00:33:57,000 --> 00:34:04,000
At first it's like, okay, it looks like it's working, but then it starts to get out into the area that defines physics.

598
00:34:04,000 --> 00:34:09,000
Not only is it getting more fascinating, but it's increasing in funniness every minute.

599
00:34:11,000 --> 00:34:14,000
Okay, you ready? I just don't want to lose it.

600
00:34:16,000 --> 00:34:18,000
Wow!

601
00:34:21,000 --> 00:34:26,000
That was like a movie. That was like the beast dying at the end of the movie.

602
00:34:28,000 --> 00:34:32,000
Well, I don't see anything on fire up there.

603
00:34:32,000 --> 00:34:34,000
That was really cool.

604
00:34:34,000 --> 00:34:39,000
I have to say, for my money, that rivals the Canyon soda.

605
00:34:39,000 --> 00:34:43,000
However, the Canyon soda, that's safe enough for any four-year-old to do.

606
00:34:43,000 --> 00:34:47,000
I mean, at least they're safe from everything except getting yelled at by their parents.

607
00:34:47,000 --> 00:34:51,000
It's not safe pretty much for any of our viewers.

608
00:34:51,000 --> 00:34:54,000
We've done it. No, you don't have to.

609
00:34:54,000 --> 00:34:59,000
Next up in the household history on X, Jamie is getting his hands dirty.

610
00:34:59,000 --> 00:35:00,000
Whatcha doing?

611
00:35:00,000 --> 00:35:02,000
Coming down and checking it out.

612
00:35:02,000 --> 00:35:04,000
I'm making a smoke bomb.

613
00:35:04,000 --> 00:35:06,000
Nice!

614
00:35:06,000 --> 00:35:10,000
With just salt, Peter, and sugar, that's it?

615
00:35:10,000 --> 00:35:13,000
You make it like a peanut bread.

616
00:35:13,000 --> 00:35:18,000
You know, you get the sugar hot and the salt, Peter, hot until it's like molasses-y.

617
00:35:18,000 --> 00:35:23,000
You can put match heads in it, apparently, so that when it cools, they're there.

618
00:35:23,000 --> 00:35:24,000
Kind of like a fuse.

619
00:35:24,000 --> 00:35:30,000
In an attempt to make a point about his manhood, Adam whips up a larger batch.

620
00:35:30,000 --> 00:35:36,000
But finds out quickly that when cooking with flammable ingredients, it can get hot in the kitchen.

621
00:35:40,000 --> 00:35:42,000
So that's what can happen.

622
00:35:42,000 --> 00:35:45,000
And that's why you don't try this at home.

623
00:35:45,000 --> 00:35:50,000
Stay with us as more household products get put under the Mythbusters microscope.

624
00:35:50,000 --> 00:35:54,000
Stay frosty, people. This is still gonna blow.

625
00:35:58,000 --> 00:36:06,000
Inspired by the diet coke and Mentos phenomenon, Adam and Jamie are trying to find their very own recipe for homemade fun.

626
00:36:06,000 --> 00:36:12,000
But so far, their experiments have been too hot for any normal household to handle.

627
00:36:12,000 --> 00:36:16,000
Now, Adam's going to find out if the smoke bomb cupcake he and Jamie baked earlier

628
00:36:16,000 --> 00:36:24,000
will rival diet coke and Mentos for spectacular fun and satisfy his desire for revenge.

629
00:36:24,000 --> 00:36:33,000
I think you all remember when Carrie and Tori decided that it would be a good idea to shock me during bagged out of battery.

630
00:36:33,000 --> 00:36:34,000
Ow!

631
00:36:36,000 --> 00:36:38,000
Do you feel God?

632
00:36:38,000 --> 00:36:44,000
Well, all I gotta say is, payback is rough.

633
00:36:44,000 --> 00:36:48,000
They say revenge is a dish best served cold.

634
00:36:48,000 --> 00:36:50,000
That is a good puff of smoke.

635
00:36:50,000 --> 00:36:52,000
Alright, let's do regular black powder.

636
00:36:52,000 --> 00:36:54,000
What is that?

637
00:36:54,000 --> 00:36:56,000
Wait.

638
00:36:59,000 --> 00:37:03,000
Is it a hockey puck? It's a flaming hockey puck.

639
00:37:07,000 --> 00:37:10,000
It's resisting.

640
00:37:10,000 --> 00:37:12,000
Put it out.

641
00:37:12,000 --> 00:37:14,000
Ah, kill it.

642
00:37:14,000 --> 00:37:19,000
So the smoke bomb cupcake was nothing but hot air.

643
00:37:19,000 --> 00:37:21,000
Okay!

644
00:37:21,000 --> 00:37:24,000
But the next test could jumpstart things.

645
00:37:24,000 --> 00:37:27,000
A hydrogen and potato chip bomb?

646
00:37:27,000 --> 00:37:32,000
The trick is that you poke a hole in the bottom and you poke a hole in the top

647
00:37:32,000 --> 00:37:36,000
and you pump in some hydrogen, some gaseous hydrogen.

648
00:37:36,000 --> 00:37:45,000
And if you do it just right and you light the top at a certain point when it reaches that golden, you know, air to fuel mixture,

649
00:37:45,000 --> 00:37:51,000
then the whole thing blows up and it will remove the tin without even disturbing the chips.

650
00:37:51,000 --> 00:37:57,000
While they get set up, let's go over to Adam who can tell us a bit more about how it works.

651
00:37:57,000 --> 00:38:04,000
You've got a can you filled with hydrogen, which is lighter than air, like helium, so it wants to rise.

652
00:38:04,000 --> 00:38:08,000
You provide a little hole for it to rise through and when you put a match over that hole,

653
00:38:08,000 --> 00:38:13,000
the hydrogen mixing with oxygen at the exit creates a little flame.

654
00:38:13,000 --> 00:38:18,000
Now, it's burning hydrogen out of the can, which means it's pulling oxygen in it from underneath.

655
00:38:18,000 --> 00:38:24,000
When the correct air fuel mixture in the can is reached, the flame up top goes down inside

656
00:38:24,000 --> 00:38:28,000
and boom! Blows that can right off the chips.

657
00:38:28,000 --> 00:38:30,000
So, let's see it in action.

658
00:38:30,000 --> 00:38:31,000
All set?

659
00:38:31,000 --> 00:38:32,000
Yep.

660
00:38:32,000 --> 00:38:34,000
Okay.

661
00:38:36,000 --> 00:38:38,000
That was fast!

662
00:38:39,000 --> 00:38:40,000
Are you okay?

663
00:38:40,000 --> 00:38:46,000
Yeah, I'm fine. I didn't wear your protection though, because you said I didn't need it.

664
00:38:46,000 --> 00:38:47,000
That's what I was told.

665
00:38:47,000 --> 00:38:52,000
It was fast and loud enough to give Jamie the shock of his life.

666
00:38:52,000 --> 00:38:57,000
But despite losing an eardrum or two, they can't wait to do it again.

667
00:38:57,000 --> 00:39:04,000
This time with ear protection and a remote control ignition system, otherwise known as a taper on a stick.

668
00:39:04,000 --> 00:39:07,000
That would be a life, wouldn't it? You heard it, right?

669
00:39:07,000 --> 00:39:09,000
Yeah, I think so.

670
00:39:09,000 --> 00:39:14,000
Adam and Jamie are uncertain because the hydrogen burns with a clear white flame.

671
00:39:14,000 --> 00:39:19,000
But, burning it is. It's pulling oxygen through the bottom of the can.

672
00:39:19,000 --> 00:39:22,000
And when the mixture is just so...

673
00:39:27,000 --> 00:39:28,000
That is very cool!

674
00:39:28,000 --> 00:39:33,000
I'd say it comes off fantastically in one sense and terrible in the other.

675
00:39:33,000 --> 00:39:41,000
Hydrogen, pure gaseous hydrogen, isn't something that everybody has, or is it something that's safe to play with?

676
00:39:41,000 --> 00:39:48,000
However, the results of blasting the can off of a stack of chips and leaving them almost intact,

677
00:39:48,000 --> 00:39:50,000
I mean, it just makes me smile, just thinking about it.

678
00:39:50,000 --> 00:39:56,000
After a timeout to think about ear protection protocol, Adam is ready for the next test.

679
00:39:56,000 --> 00:39:59,000
This is what I've known about for a long time. It's called dry ice bomb.

680
00:39:59,000 --> 00:40:03,000
Years ago, I went to an ice company to pick up some stuff for Jamie.

681
00:40:03,000 --> 00:40:05,000
It's like 20 years ago, 15 years ago.

682
00:40:05,000 --> 00:40:08,000
And it said, you cannot buy dry ice unless you're 18.

683
00:40:08,000 --> 00:40:10,000
And I thought, why would that be?

684
00:40:10,000 --> 00:40:13,000
And so I said, hey, how come you can't buy dry ice unless you're over 18?

685
00:40:13,000 --> 00:40:18,000
And the guy goes, oh, because you can stick it in a 2 liter bottle and make a huge bomb out of it.

686
00:40:18,000 --> 00:40:23,000
It blows up and it, like, set car alarms off across the street. It's really cool.

687
00:40:23,000 --> 00:40:27,000
And I was thinking, you're new here, aren't you?

688
00:40:28,000 --> 00:40:31,000
Since then, I have always wanted to try it.

689
00:40:32,000 --> 00:40:40,000
So apparently with nothing more than a 2 liter soda bottle and some dry ice, there's some big boom fun to be had.

690
00:40:40,000 --> 00:40:44,000
But Adam is slightly concerned with safety on this one.

691
00:40:44,000 --> 00:40:49,000
Look at it this way. I'm crazy. And even I'm putting on a massive amount of padding to do this one.

692
00:40:49,000 --> 00:40:51,000
Oh yeah, the cod piece.

693
00:40:51,000 --> 00:40:54,000
Meanwhile, Jamie is working on the dry ice.

694
00:40:54,000 --> 00:40:59,000
I'm cutting the dry ice up because we need to fit it into the neck of the bottle.

695
00:40:59,000 --> 00:41:07,000
Once it's in there, we're going to add water to it, which has the amazing effect of melting the ice really quickly.

696
00:41:07,000 --> 00:41:13,000
It turns it all into gas and all that gas has to go somewhere.

697
00:41:13,000 --> 00:41:19,000
So add a little water to the dry ice in the bottle and the dry ice turns into CO2 gas.

698
00:41:19,000 --> 00:41:24,000
And with the lid secured, Adam and Jamie have a pressure vessel on their hands.

699
00:41:24,000 --> 00:41:28,000
Now, it's just a matter of time.

700
00:41:28,000 --> 00:41:30,000
Huge dramatic music.

701
00:41:31,000 --> 00:41:33,000
It's going to go any second, I swear.

702
00:41:33,000 --> 00:41:36,000
Stay frosty, people. This is still going to blow.

703
00:41:37,000 --> 00:41:42,000
It's kind of like watching the grass grow except there's an explosion at the end of it.

704
00:41:44,000 --> 00:41:46,000
Wow!

705
00:41:49,000 --> 00:41:53,000
Dude, that is intensely loud.

706
00:41:53,000 --> 00:41:55,000
I've got to say that's louder than a gunshot.

707
00:41:55,000 --> 00:41:58,000
Now you see it, now you don't.

708
00:41:59,000 --> 00:42:05,000
And what was a plastic soda bottle is now a million pieces of twisted shrapnel.

709
00:42:05,000 --> 00:42:06,000
That is amazing.

710
00:42:06,000 --> 00:42:20,000
That's one of those things it is, you know, it doesn't look like much, but it's such a shockwave that, you know, I can't imagine this killing you, but I wouldn't want to be anywhere near it when it goes off.

711
00:42:20,000 --> 00:42:27,000
It would be a hell of a lot of trauma. You would definitely lose your hearing if you were anywhere near this thing.

712
00:42:30,000 --> 00:42:35,000
Well, you know, this is a lot of fun, but I don't think anything we came up with came close to the candy and soda.

713
00:42:35,000 --> 00:42:39,000
I mean, it is one of the most perfect parlor tricks I've ever seen.

714
00:42:39,000 --> 00:42:47,000
Not only is it spectacular, not only is it totally safe, but everything you need to do it, you can get at literally any store there is.

715
00:42:47,000 --> 00:42:53,000
Yeah, we kind of cheated a little bit. Not everything we used was household per se.

716
00:42:53,000 --> 00:43:01,000
Yeah, I have no doubt that the very morning after this episode airs, you and I will have thousands of suggestions of other new things to try.

717
00:43:01,000 --> 00:43:05,000
Maybe that's another episode, but I think we can put this one to bed and go home.
