1
00:00:00,000 --> 00:00:05,000
on this episode of myth busters

2
00:00:05,000 --> 00:00:08,000
we expected something and something happened

3
00:00:08,000 --> 00:00:13,000
Adam and Jamie have a movie myth they were born for

4
00:00:13,000 --> 00:00:16,000
can a gas leak and a magazine and a toaster

5
00:00:16,000 --> 00:00:19,000
but a little bit it's not going to be very happy in here

6
00:00:19,000 --> 00:00:21,000
make a room go kaboom

7
00:00:21,000 --> 00:00:23,000
I love running for safety

8
00:00:23,000 --> 00:00:25,000
then I'm starting to get a little nervous

9
00:00:25,000 --> 00:00:30,000
Carrie Grant and Tori tackle the tall tale of blue eyes

10
00:00:30,000 --> 00:00:32,000
that is incredible

11
00:00:32,000 --> 00:00:36,000
can the contents of an airplane's toilet really fall from the sky

12
00:00:36,000 --> 00:00:38,000
that thing is hauling

13
00:00:38,000 --> 00:00:40,000
in one frozen chunk

14
00:00:40,000 --> 00:00:42,000
this is an awesome day

15
00:00:44,000 --> 00:00:46,000
who are the myth busters?

16
00:00:46,000 --> 00:00:48,000
Adam Savage

17
00:00:48,000 --> 00:00:49,000
oh god

18
00:00:49,000 --> 00:00:50,000
and Jamie Heineman

19
00:00:50,000 --> 00:00:52,000
am I really that ugly?

20
00:00:52,000 --> 00:00:56,000
between them more than 30 years of special effects experience

21
00:00:56,000 --> 00:00:58,000
joining them

22
00:00:58,000 --> 00:01:00,000
Grant Imahara

23
00:01:00,000 --> 00:01:02,000
Carrie Byron

24
00:01:02,000 --> 00:01:04,000
time to wreck this car

25
00:01:04,000 --> 00:01:06,000
and Tori Bellegi

26
00:01:06,000 --> 00:01:08,000
we survived

27
00:01:08,000 --> 00:01:10,000
they don't just tell them this

28
00:01:11,000 --> 00:01:13,000
they put them to the test

29
00:01:23,000 --> 00:01:25,000
have you seen the born supremacy?

30
00:01:25,000 --> 00:01:26,000
I love that movie

31
00:01:26,000 --> 00:01:28,000
I love the whole born trilogy

32
00:01:28,000 --> 00:01:30,000
have you got a myth from supremacy we can test?

33
00:01:30,000 --> 00:01:32,000
there's a scene where born broke into an apartment

34
00:01:32,000 --> 00:01:34,000
and he knows the bad guys are coming

35
00:01:34,000 --> 00:01:36,000
so he has to make an escape

36
00:01:36,000 --> 00:01:38,000
what he does is he breaks the gas line

37
00:01:38,000 --> 00:01:40,000
where it goes into the stove to let the gas flow

38
00:01:40,000 --> 00:01:42,000
he grabs a magazine, shoves it in the toaster

39
00:01:42,000 --> 00:01:44,000
sets the toaster on

40
00:01:44,000 --> 00:01:46,000
and 20 seconds later

41
00:01:46,000 --> 00:01:48,000
when the magazine sets on fire

42
00:01:48,000 --> 00:01:50,000
the whole apartment blows up

43
00:01:52,000 --> 00:01:54,000
and so born makes his escape

44
00:01:54,000 --> 00:01:57,000
that's like perfect for us to test

45
00:01:57,000 --> 00:02:00,000
I think I have a pretty good idea where we should start

46
00:02:00,000 --> 00:02:04,000
okay but before you tell me I actually want to demonstrate how much I love the born movies

47
00:02:04,000 --> 00:02:06,000
you know I collect movie props

48
00:02:06,000 --> 00:02:09,000
this is actually Jason Bourne's red bag from the Bourne identity

49
00:02:09,000 --> 00:02:11,000
in the wastebasket from the Swiss bank

50
00:02:11,000 --> 00:02:13,000
not only that it's actually full

51
00:02:13,000 --> 00:02:16,000
of all of the props that were actually in that bag in the film

52
00:02:16,000 --> 00:02:19,000
all his trinkets and even his stunt pistol

53
00:02:19,000 --> 00:02:21,000
it's made of rubber isn't that cool?

54
00:02:23,000 --> 00:02:26,000
we need to find out whether a magazine would actually set on fire

55
00:02:26,000 --> 00:02:28,000
when it's put in a toaster

56
00:02:28,000 --> 00:02:30,000
okay

57
00:02:32,000 --> 00:02:35,000
there are three ingredients to this born style getaway

58
00:02:35,000 --> 00:02:37,000
the toaster, the magazine

59
00:02:37,000 --> 00:02:39,000
and the natural gas

60
00:02:39,000 --> 00:02:41,000
and first in the mix are one and two

61
00:02:41,000 --> 00:02:44,000
how long does it take to toast a magazine?

62
00:02:44,000 --> 00:02:46,000
you ready? I'm ready

63
00:02:46,000 --> 00:02:47,000
alright

64
00:02:47,000 --> 00:02:51,000
the guys start the clock using a magazine like the one in the movie

65
00:02:51,000 --> 00:02:54,000
and the toaster rigged to stay on

66
00:02:54,000 --> 00:02:58,000
you know in the movie it was already on fire at this point

67
00:02:58,000 --> 00:03:04,000
as it turns out toasting a magazine takes a little longer than the twenty seconds of the film

68
00:03:04,000 --> 00:03:06,000
oh three minutes over schedule

69
00:03:06,000 --> 00:03:08,000
I think we're really close

70
00:03:08,000 --> 00:03:12,000
in fact it takes over twelve minutes before they get ignition

71
00:03:12,000 --> 00:03:14,000
hey we got fire

72
00:03:17,000 --> 00:03:20,000
remember kids we're professionals

73
00:03:22,000 --> 00:03:28,000
so reality is twelve minutes versus the movie's twenty five some odd seconds

74
00:03:28,000 --> 00:03:29,000
hey we got fire

75
00:03:29,000 --> 00:03:30,000
what do you think?

76
00:03:30,000 --> 00:03:34,000
well what I think is that this magazine is a worst case scenario

77
00:03:34,000 --> 00:03:37,000
because look how thick those pages are

78
00:03:37,000 --> 00:03:40,000
and magazines are all different shapes and sizes

79
00:03:40,000 --> 00:03:42,000
so you think we should try a whole bunch of different kinds of magazines

80
00:03:42,000 --> 00:03:45,000
and see if they have different rates at which they catch on fire

81
00:03:45,000 --> 00:03:46,000
exactly

82
00:03:46,000 --> 00:03:47,000
I love it let's do it

83
00:03:48,000 --> 00:03:50,000
lots of toasters now

84
00:03:50,000 --> 00:03:54,000
it's clear the real world magazine doesn't light up like its movie counterpart

85
00:03:54,000 --> 00:03:58,000
so now the mythbusters are on the trail of a best case scenario

86
00:03:59,000 --> 00:04:02,000
in order to cover our basis here and working up the theory that different types of magazines

87
00:04:02,000 --> 00:04:06,000
composed of different kinds of paper are going to catch a light at different rates

88
00:04:06,000 --> 00:04:09,000
we're about to put a half dozen of them to the test

89
00:04:09,000 --> 00:04:12,000
everything from our original magazine to something much harder to catch on fire

90
00:04:12,000 --> 00:04:16,000
comic book, something that will probably catch on fire in like seconds

91
00:04:16,000 --> 00:04:19,000
we're gonna put one in each of these toasters start this timer

92
00:04:19,000 --> 00:04:21,000
and log how long each of them takes to catch a light

93
00:04:21,000 --> 00:04:23,000
what could be more fun?

94
00:04:23,000 --> 00:04:26,000
well with the six magazines in place

95
00:04:26,000 --> 00:04:29,000
let the char grilling challenge commence

96
00:04:29,000 --> 00:04:33,000
we're experimentally doing something that should just never ever be done

97
00:04:33,000 --> 00:04:34,000
I like that

98
00:04:35,000 --> 00:04:36,000
oh flame

99
00:04:36,000 --> 00:04:37,000
number three

100
00:04:37,000 --> 00:04:39,000
one minute forty seconds

101
00:04:39,000 --> 00:04:43,000
this time around it seems the contenders are a little quicker to toast

102
00:04:44,000 --> 00:04:46,000
it's two twenty

103
00:04:46,000 --> 00:04:48,000
yep here we go

104
00:04:48,000 --> 00:04:49,000
number four

105
00:04:49,000 --> 00:04:51,000
three minutes fifteen seconds

106
00:04:51,000 --> 00:04:54,000
go number one three minutes twenty seconds

107
00:04:54,000 --> 00:04:57,000
let's listen for that sound

108
00:04:58,000 --> 00:04:59,000
there we go

109
00:04:59,000 --> 00:05:00,000
there it is

110
00:05:00,000 --> 00:05:02,000
four minutes thirty six seconds

111
00:05:02,000 --> 00:05:04,000
and finally bring it up the rear

112
00:05:04,000 --> 00:05:05,000
there it is

113
00:05:05,000 --> 00:05:08,000
is the original magazine at twelve minutes

114
00:05:10,000 --> 00:05:15,000
as we suspected it does make a difference what kind of magazine is stuffed in the toaster

115
00:05:15,000 --> 00:05:19,000
the best case scenario is something that amounts to common newsprint

116
00:05:19,000 --> 00:05:24,000
but even that took about three times as long as what it did in the movie

117
00:05:24,000 --> 00:05:26,000
interesting

118
00:05:26,000 --> 00:05:34,000
so it's clear that even with the best case scenario magazine toaster ignition takes a lot longer than the twenty seconds it took born

119
00:05:35,000 --> 00:05:39,000
and now to test the next ingredient of this explosive combination

120
00:05:39,000 --> 00:05:41,000
the methane

121
00:05:41,000 --> 00:05:43,000
now methane here is a natural gas

122
00:05:43,000 --> 00:05:46,000
and it's most of what comes out of your stove at home to cook with

123
00:05:46,000 --> 00:05:49,000
it's a flammable gas but it's not flammable on its own

124
00:05:49,000 --> 00:05:53,000
it actually requires a certain amount of oxygen out of the air in order to burn

125
00:05:53,000 --> 00:05:55,000
how much oxygen?

126
00:05:55,000 --> 00:05:57,000
well that actually turns out to be a very particular relationship

127
00:05:57,000 --> 00:06:01,000
the relationship of oxygen to flammable gas is called stoichiometry

128
00:06:02,000 --> 00:06:06,000
to create fire it takes heat, fuel and oxygen

129
00:06:06,000 --> 00:06:12,000
and when it comes to flammable gases the amount of fuel to oxygen is a complex relationship called

130
00:06:12,000 --> 00:06:14,000
stoichiometry

131
00:06:14,000 --> 00:06:16,000
too much fuel or too little

132
00:06:16,000 --> 00:06:18,000
and there'll be nothing close to a flame

133
00:06:18,000 --> 00:06:21,000
but get the perfect mixture and you get an explosion

134
00:06:22,000 --> 00:06:29,000
now according to the movie it took born twenty seconds to get that explosive ratio of air to gas just right

135
00:06:29,000 --> 00:06:34,000
so now the mythbusters are dialing in to find out exactly what it is

136
00:06:35,000 --> 00:06:44,000
we know that if we're going to get methane to burn we need a ratio of between 6 and 17% fuel to air

137
00:06:44,000 --> 00:06:48,000
the ideal range is about 9% methane in the rest of air

138
00:06:48,000 --> 00:06:51,000
what we don't know is what that actually means

139
00:06:51,000 --> 00:06:54,000
does that mean if we are a little off we get sort of a woof

140
00:06:54,000 --> 00:06:58,000
but if we get right at the 9% we're getting a real strong bang

141
00:06:58,000 --> 00:07:02,000
before we go full scale we want to really know what we're doing

142
00:07:02,000 --> 00:07:08,000
so what we've done is make a 10 inch by 10 inch by 10 inch cubic box

143
00:07:08,000 --> 00:07:14,000
and that will allow us to really easily dial in on these ratios to see what it means

144
00:07:14,000 --> 00:07:18,000
and while Jamie is boxing Adam has the ratios in the bag

145
00:07:18,000 --> 00:07:22,000
one of the ratios I want to play with is 9% flammable gas to air

146
00:07:22,000 --> 00:07:26,000
this bag holds 9% of the volume of this chamber

147
00:07:26,000 --> 00:07:28,000
I will fill it with gas

148
00:07:29,000 --> 00:07:32,000
I will then hook it up to the chamber

149
00:07:32,000 --> 00:07:35,000
open up both of the valves

150
00:07:35,000 --> 00:07:37,000
press the gas into the chamber

151
00:07:37,000 --> 00:07:40,000
I'll be displacing air that comes out of this little hole right here

152
00:07:40,000 --> 00:07:45,000
seal it up, walk away, ignite it with a neon transformer and see what happens

153
00:07:45,000 --> 00:07:51,000
Adam's bags will help the guy zone in on exactly what ratio of methane to air is explosive

154
00:07:51,000 --> 00:07:53,000
and speaking of methane

155
00:07:53,000 --> 00:07:58,000
so that we can ignite this thing safely we're going to remotely turn on this neon transformer

156
00:07:58,000 --> 00:08:02,000
that will create a high voltage spark inside the methane chamber

157
00:08:02,000 --> 00:08:08,000
and here we'll be able to vary the methane concentrations, ignite it and see what we get

158
00:08:08,000 --> 00:08:13,000
first up, a test at the very bottom of the stoichiometric zone, 6%

159
00:08:13,000 --> 00:08:14,000
we're good

160
00:08:14,000 --> 00:08:16,000
okay, 6%

161
00:08:16,000 --> 00:08:20,000
and 3, 2, 1

162
00:08:24,000 --> 00:08:27,000
we expected something and something happened

163
00:08:32,000 --> 00:08:36,000
a fragile box separated just as we hoped it would

164
00:08:36,000 --> 00:08:38,000
and it's actually kind of a little bit of a...

165
00:08:38,000 --> 00:08:39,000
boom

166
00:08:39,000 --> 00:08:42,000
I was expecting a little more from an explosion

167
00:08:42,000 --> 00:08:46,000
and I'm interested to see if our optimal stoichiometric ratio gives us that

168
00:08:46,000 --> 00:08:47,000
me too

169
00:08:47,000 --> 00:08:48,000
well let's set it up

170
00:08:48,000 --> 00:08:49,000
okay

171
00:08:49,000 --> 00:08:56,000
6% is explosive, but what if Borne achieved the optimal ratio of 9% methane to air

172
00:08:56,000 --> 00:09:00,000
9% and 3, 2, 1

173
00:09:04,000 --> 00:09:06,000
well that was more energetic

174
00:09:06,000 --> 00:09:09,000
9% was definitely more energetic

175
00:09:09,000 --> 00:09:15,000
but for Adam the surprising thing is that at both ratios they scored the mythical explosion they're looking for

176
00:09:16,000 --> 00:09:18,000
this is awesome

177
00:09:18,000 --> 00:09:21,000
we think that 6% means we'll see a small pop

178
00:09:21,000 --> 00:09:23,000
9% means we'll see a big pop

179
00:09:23,000 --> 00:09:25,000
in this case that's not the case

180
00:09:25,000 --> 00:09:27,000
and that actually makes it look better for this myth

181
00:09:27,000 --> 00:09:31,000
if we're getting a pop at the very lowest end of the stoichiometric range

182
00:09:31,000 --> 00:09:38,000
that's making Borne's use of this as a diversion technique more feasible

183
00:09:38,000 --> 00:09:41,000
I'm not saying it's probable, but it's making it look more feasible

184
00:09:46,000 --> 00:09:47,000
it ain't pretty but it's home

185
00:09:47,000 --> 00:09:49,000
but can the myth bring it down

186
00:09:49,000 --> 00:09:54,000
and Carrie takes to the skies on the tale of blue ice

187
00:09:54,000 --> 00:09:55,000
both?

188
00:10:07,000 --> 00:10:08,000
you're looking excited

189
00:10:08,000 --> 00:10:12,000
that's because we have a myth that's spectacular, gross and challenging

190
00:10:12,000 --> 00:10:13,000
I'll wrap it up into one

191
00:10:13,000 --> 00:10:14,000
what's the story?

192
00:10:14,000 --> 00:10:17,000
it's the one where the pilot jettisons the contents of an airplane toilet

193
00:10:17,000 --> 00:10:21,000
which promptly freezes its altitude and turns into a deadly projectile

194
00:10:21,000 --> 00:10:23,000
you're talking about the myth of blue ice

195
00:10:23,000 --> 00:10:24,000
exactly

196
00:10:27,000 --> 00:10:31,000
when mysterious substances of suspect origin fall from the sky

197
00:10:31,000 --> 00:10:34,000
urban myths are sure to follow

198
00:10:35,000 --> 00:10:39,000
and the conspiracy theory that has the message boards in a spin

199
00:10:39,000 --> 00:10:41,000
is the infamous blue ice

200
00:10:41,000 --> 00:10:43,000
and here's how it happens

201
00:10:44,000 --> 00:10:51,000
on a bright sunny day, a passing pilot supposedly jettisons the contents of the toilet's tank

202
00:10:51,000 --> 00:10:56,000
and apparently at high altitudes, the sub-zero temperatures freeze the liquid

203
00:10:56,000 --> 00:11:00,000
into a damaging and disgusting missile

204
00:11:01,000 --> 00:11:05,000
alright, we know a little bit about airplane toilets because we did a myth on them

205
00:11:07,000 --> 00:11:10,000
we know for a fact you can't get sucked into them if you're sitting down

206
00:11:10,000 --> 00:11:14,000
and we know the reason why it's blue is because they use that chemical to cover the smell

207
00:11:14,000 --> 00:11:17,000
but what we don't know is, what happens to the waste?

208
00:11:17,000 --> 00:11:20,000
yeah, can you actually eject the contents in mid-air?

209
00:11:20,000 --> 00:11:22,000
I guess this is where we start

210
00:11:23,000 --> 00:11:30,000
so first up, Carrie hits Stockton Airport to find out when and how a pilot dumps his waste

211
00:11:31,000 --> 00:11:34,000
so you're an airplane technician, what do you think of our old blue ice myth?

212
00:11:34,000 --> 00:11:37,000
well, Carrie, as you can see from this cockpit

213
00:11:37,000 --> 00:11:42,000
there are thousands of buttons and switches of which none are labeled, dump the toilet

214
00:11:43,000 --> 00:11:45,000
which is bad news for the myth

215
00:11:45,000 --> 00:11:51,000
but if the pilot can't jettison the John mid-flight, is there anyway the liquid blue waste can escape?

216
00:11:52,000 --> 00:11:54,000
failure of components

217
00:11:54,000 --> 00:11:57,000
so there could be a mechanical problem that causes blue ice instead of the pilot?

218
00:11:57,000 --> 00:12:01,000
yes, like with most systems on an airplane there are redundancies

219
00:12:01,000 --> 00:12:03,000
and with the lab it's no different

220
00:12:03,000 --> 00:12:08,000
yep, there are three fail safes that have to be breached in order for the liquid to leak

221
00:12:08,000 --> 00:12:10,000
the dump valve on the holding tank

222
00:12:10,000 --> 00:12:15,000
and two watertight seals leading to the exterior of the fuselage

223
00:12:15,000 --> 00:12:19,000
if all three of those components fail, that's a problem

224
00:12:20,000 --> 00:12:22,000
it's not likely, is it possible?

225
00:12:22,000 --> 00:12:26,000
absolutely, multiple components that fail leading to a problem

226
00:12:26,000 --> 00:12:28,000
this myth is looking good

227
00:12:28,000 --> 00:12:30,000
there's my baby

228
00:12:31,000 --> 00:12:33,000
all right, Carrie, so how did it go?

229
00:12:33,000 --> 00:12:37,000
well, part of this myth isn't looking good, there's no way for the pilot to jettison the contents of the toilet

230
00:12:37,000 --> 00:12:40,000
true, but that doesn't rule out ice falling off the plane

231
00:12:40,000 --> 00:12:43,000
that's right, there's still two scenarios that could happen

232
00:12:43,000 --> 00:12:48,000
there could be a major malfunction that leads to either all of the contents coming out at once, freezing and falling to earth

233
00:12:48,000 --> 00:12:51,000
or you could get a nice slow leak that created an ice ball

234
00:12:51,000 --> 00:12:53,000
now the question is, how are we going to test them?

235
00:12:53,000 --> 00:12:55,000
actually, we've been talking to our friends at NASA

236
00:12:55,000 --> 00:12:58,000
and they've agreed to let us use their icing research tunnel

237
00:12:58,000 --> 00:13:02,000
which can simultaneously duplicate temperatures of minus 20 degrees

238
00:13:02,000 --> 00:13:05,000
and wind speeds of up to 250 knots

239
00:13:05,000 --> 00:13:07,000
that is the perfect conditions for high altitude

240
00:13:07,000 --> 00:13:11,000
well, it sounds like before we leave, we're going to have to build a leaky airplane toilet

241
00:13:13,000 --> 00:13:18,000
now, this myth is about airplanes, but in order to test it, we don't need to build a full airplane

242
00:13:18,000 --> 00:13:23,000
all we need to do is make something that has similar aerodynamic properties

243
00:13:23,000 --> 00:13:25,000
so, this is our design

244
00:13:25,000 --> 00:13:29,000
and this will have low drag and

245
00:13:31,000 --> 00:13:34,000
a place to leak, which are the most important things

246
00:13:34,000 --> 00:13:40,000
so for their tests at NASA, Cary builds a waste system designed to fail in two ways

247
00:13:40,000 --> 00:13:42,000
either with a slow leak

248
00:13:42,000 --> 00:13:44,000
or a catastrophic dump

249
00:13:45,000 --> 00:13:48,000
now, according to NASA's specs, it had to be out of aluminum

250
00:13:48,000 --> 00:13:49,000
because that's what airplanes are made of

251
00:13:49,000 --> 00:13:51,000
and we were not allowed to weld anything

252
00:13:51,000 --> 00:13:54,000
because they didn't want anything breaking apart inside the wind tunnel

253
00:13:54,000 --> 00:13:57,000
because there's going to be so much pressure created by the wind

254
00:13:57,000 --> 00:14:03,000
so, we had to drill and rivet over 600 rivets to put our airplane together

255
00:14:03,000 --> 00:14:05,000
and what we have right here is our valve

256
00:14:05,000 --> 00:14:07,000
this is what we're going to have hooked up to a water tank

257
00:14:07,000 --> 00:14:09,000
and we're going to be doing two tests

258
00:14:09,000 --> 00:14:11,000
one where we dump the water completely

259
00:14:11,000 --> 00:14:13,000
and then one where there's a slow leak

260
00:14:13,000 --> 00:14:17,000
to find out, can you grow a chunk of ice on the side of a plane?

261
00:14:21,000 --> 00:14:25,000
Jason Bourne knows how to make an explosive exit

262
00:14:25,000 --> 00:14:30,000
but could a magazine and a toaster really toast a gas-filled apartment?

263
00:14:32,000 --> 00:14:37,000
after getting to know their enemy in the shop, the guys are ready to go full scale

264
00:14:42,000 --> 00:14:46,000
if we're going to replicate the natural gas explosion in the sky's apartment from the movie

265
00:14:46,000 --> 00:14:48,000
we're going to need clearly two things

266
00:14:48,000 --> 00:14:51,000
yeah, they said get your own show with a lopet all sorts of doors

267
00:14:51,000 --> 00:14:55,000
one is methane, natural gas, which is easy to get

268
00:14:55,000 --> 00:14:58,000
and two is the guy's apartment, which we don't actually have

269
00:14:58,000 --> 00:15:01,000
so, we've come out to the bomb range where they've got plenty of room

270
00:15:01,000 --> 00:15:05,000
and in a few hours, we're going to build this guy's apartment

271
00:15:05,000 --> 00:15:09,000
not to code, we just need it to be a gas containment device

272
00:15:09,000 --> 00:15:13,000
in the shape of the apartment, but it will be properly appointed, I'm sure

273
00:15:13,000 --> 00:15:20,000
so to find out if you really can get a room to kaboom with just gas, a magazine and a toaster

274
00:15:20,000 --> 00:15:24,000
they'll precisely replicate the circumstances of the movie

275
00:15:24,000 --> 00:15:28,000
starting with the apartment dimensions, 16 by 32 feet

276
00:15:28,000 --> 00:15:31,000
once the roof has been successfully raised

277
00:15:31,000 --> 00:15:36,000
it's time for the resident exterior decorator to take over

278
00:15:36,000 --> 00:15:42,000
after you blow enough things up, you start to look for aesthetic finesse in the explosion

279
00:15:42,000 --> 00:15:46,000
I'll give you an example, first hot water heater, we painted that little house red

280
00:15:51,000 --> 00:15:53,000
look at that, isn't that beautiful?

281
00:15:53,000 --> 00:15:56,000
so we're going to give the same treatment to this thing, we're going to paint the outside

282
00:15:56,000 --> 00:16:01,000
and lovely orange so that when it finally blows up, the high speed shot will be especially gorgeous

283
00:16:01,000 --> 00:16:05,000
well it certainly will be explosively tangerine

284
00:16:10,000 --> 00:16:15,000
there, I wouldn't call it livable, but I'd call it blow-up-able

285
00:16:15,000 --> 00:16:22,000
it is blow-up-able and the final finishing touches are to furnish it before they step on the gas

286
00:16:23,000 --> 00:16:28,000
excellent, that's got a nice view here, you know, the valley out the window there

287
00:16:29,000 --> 00:16:33,000
the house may be complete, but soon it'll be filled with highly flammable gas

288
00:16:33,000 --> 00:16:38,000
and in the event they don't get a ignition, Adam has created this

289
00:16:38,000 --> 00:16:43,000
what I've got here is an exhaust system so that I can evacuate the gas from this room

290
00:16:43,000 --> 00:16:47,000
because one of the most dangerous things that could happen to us in this experiment is nothing

291
00:16:47,000 --> 00:16:52,000
we found this on cell phone destroy gas station, we had a room full of gasoline fumes

292
00:16:52,000 --> 00:16:56,000
and we didn't get it to ignite and nobody wants to approach a room full of fumes

293
00:16:56,000 --> 00:16:58,000
hello explosion, hello

294
00:16:58,000 --> 00:17:03,000
so if nothing happens, I've got a switch I can turn that will start these fans all up

295
00:17:03,000 --> 00:17:07,000
and get all the gas out of this room so it's safe to do a reset

296
00:17:07,000 --> 00:17:12,000
I think that's the last piece of the puzzle, I'll get to a safe location

297
00:17:12,000 --> 00:17:16,000
and that's not the only safety precaution they're taking with this test

298
00:17:17,000 --> 00:17:20,000
this is our methane outlet which has tinsel on it

299
00:17:20,000 --> 00:17:25,000
which we will be able to see moving if gas is coming through here on our remote camera

300
00:17:27,000 --> 00:17:31,000
this is our tank of methane, we have a regulator and a flow meter attached to it

301
00:17:31,000 --> 00:17:36,000
now this rig is set up to give us the same kind of input of gas into our house

302
00:17:36,000 --> 00:17:41,000
as you would normally have in a domestic gas line going into an apartment

303
00:17:41,000 --> 00:17:46,000
now this valve here I have with a line attached to it that goes to our bunker

304
00:17:46,000 --> 00:17:51,000
and I'm going to pull on this line if there's anything that bothers me about this setting

305
00:17:51,000 --> 00:17:54,000
because you know it's gas, it's flammable

306
00:17:54,000 --> 00:17:57,000
if there's something we don't like we want to be able to shut it off

307
00:17:59,000 --> 00:18:03,000
and from this distance I can safely pull the plug if there's something I don't like

308
00:18:04,000 --> 00:18:07,000
the list of things Jamie doesn't like may be a long one

309
00:18:07,000 --> 00:18:10,000
but if the explosion of the movie is anything to go by

310
00:18:10,000 --> 00:18:14,000
putting this myth to the test could be very dangerous

311
00:18:14,000 --> 00:18:16,000
well shall we get started?

312
00:18:16,000 --> 00:18:17,000
yeah

313
00:18:17,000 --> 00:18:18,000
after you

314
00:18:20,000 --> 00:18:22,000
next up it's full speed ahead

315
00:18:22,000 --> 00:18:24,000
all stations reporting with a go no go

316
00:18:24,000 --> 00:18:27,000
but will the blue ice myth be blown away?

317
00:18:33,000 --> 00:18:37,000
Carrie Grant and Tori are tackling the infamous tall tale of blue ice

318
00:18:37,000 --> 00:18:42,000
can a leaking toilet midair lead to a deadly chunk of ice down there

319
00:18:46,000 --> 00:18:47,000
to find out for sure

320
00:18:48,000 --> 00:18:49,000
cool

321
00:18:53,000 --> 00:18:55,000
all stations reporting with a go no go

322
00:18:58,000 --> 00:19:02,000
because this place has a heap of hardcore hardware

323
00:19:02,000 --> 00:19:05,000
this massive fan is the heart of NASA's icing tunnel

324
00:19:05,000 --> 00:19:10,000
it's powered by 5000 horsepower direct drive electric motor

325
00:19:10,000 --> 00:19:15,000
it has 12 individual custom fan blades for a diameter of 25 feet

326
00:19:15,000 --> 00:19:19,000
it's capable of generating wind speeds over 300 knots

327
00:19:19,000 --> 00:19:21,000
and that's only half the equation

328
00:19:21,000 --> 00:19:23,000
this is the other half of the equation

329
00:19:23,000 --> 00:19:25,000
the icing tunnel itself

330
00:19:25,000 --> 00:19:27,000
the wind comes rushing through here

331
00:19:27,000 --> 00:19:29,000
refrigerated to minus 20 degrees Fahrenheit

332
00:19:30,000 --> 00:19:32,000
those are the spectacular specs

333
00:19:32,000 --> 00:19:34,000
and now to put them to good use

334
00:19:34,000 --> 00:19:39,000
the way we're going to test this is we're going to stick our section of fuselage into their wind tunnel

335
00:19:39,000 --> 00:19:41,000
this is me now in the R2-D2

336
00:19:41,000 --> 00:19:42,000
oh boy

337
00:19:42,000 --> 00:19:47,000
and recreate the same wind speeds and temperatures that you would find at altitude

338
00:19:47,000 --> 00:19:50,000
then we're going to create a leak inside the valve

339
00:19:50,000 --> 00:19:57,000
let it sit there and see if those conditions will cause that blue liquid to form into a chunk of ice

340
00:19:57,000 --> 00:20:01,000
remember there are two leaky valve scenarios the team will test

341
00:20:01,000 --> 00:20:04,000
and first up is the catastrophic dump

342
00:20:05,000 --> 00:20:07,000
we have our model in position we're ready to go

343
00:20:07,000 --> 00:20:09,000
alright fire it up

344
00:20:09,000 --> 00:20:11,000
alright let's go fire it up

345
00:20:11,000 --> 00:20:13,000
maximum warp

346
00:20:13,000 --> 00:20:15,000
oh sorry just made that really deep

347
00:20:15,000 --> 00:20:17,000
we're trying to make science cool dude

348
00:20:17,000 --> 00:20:18,000
here we go

349
00:20:18,000 --> 00:20:21,000
and for cool science let's make it so

350
00:20:24,000 --> 00:20:28,000
the fan winds up whipping up a 290 mile an hour wind speed

351
00:20:29,000 --> 00:20:35,000
then the heat exchanger drops the air temperature to a high altitude minus 20 degrees Celsius

352
00:20:36,000 --> 00:20:39,000
our model is holding together perfectly

353
00:20:40,000 --> 00:20:44,000
then they're ready to pull the pin on the catastrophic failure test

354
00:20:44,000 --> 00:20:48,000
will the blue liquid instantly freeze into a chunk of blue ice

355
00:20:49,000 --> 00:20:56,000
so this is full tagged up in 3, 2, 1, go

356
00:21:00,000 --> 00:21:02,000
oh my god

357
00:21:03,000 --> 00:21:05,000
look at how fast it's going out

358
00:21:05,000 --> 00:21:07,000
that is awesome

359
00:21:08,000 --> 00:21:13,000
as soon as the liquid exits the aircraft it's ripped away by the shearing force of the wind

360
00:21:13,000 --> 00:21:19,000
and despite the bitterly cold air temperatures it's unable to form the mythical slice of ice

361
00:21:21,000 --> 00:21:27,000
so behind me are the results of our complete release test where we dumped the entire contents of the waste tank

362
00:21:27,000 --> 00:21:32,000
now it didn't atomize all the way because you can see some of it formed on the surface here

363
00:21:32,000 --> 00:21:37,000
but it also did not form one big chunk that could fall on some

364
00:21:37,000 --> 00:21:41,000
yep although most of the blue waste was vaporized on contact with the wind

365
00:21:41,000 --> 00:21:46,000
some did form a thin layer just not enough for a blue icicle

366
00:21:47,000 --> 00:21:51,000
but I mean it's incredible we got an actual layer of ice and pretty quickly

367
00:21:51,000 --> 00:21:54,000
alright well let's try again and this time have a slow leak

368
00:21:54,000 --> 00:21:57,000
alright let's see if that gives us a big chunk of ice

369
00:21:57,000 --> 00:22:01,000
once again the NASA techs simulate the same high altitude conditions

370
00:22:01,000 --> 00:22:05,000
and then sabotage the plumbing for the drip test

371
00:22:06,000 --> 00:22:08,000
and once the leak is leaking

372
00:22:10,000 --> 00:22:11,000
oh my god

373
00:22:11,000 --> 00:22:13,000
oh look how quick the ice is building up

374
00:22:13,000 --> 00:22:16,000
the results are as astonishing as they are immediate

375
00:22:16,000 --> 00:22:18,000
this is looking great and it's blue

376
00:22:18,000 --> 00:22:20,000
that is fantastic

377
00:22:20,000 --> 00:22:22,000
it hasn't even been 2 minutes yet

378
00:22:23,000 --> 00:22:24,000
oh my gosh

379
00:22:24,000 --> 00:22:26,000
that is incredible

380
00:22:28,000 --> 00:22:33,000
the liquid moving over the surface of the aircraft is protected from the extreme wind speeds

381
00:22:33,000 --> 00:22:36,000
by what's called a boundary layer

382
00:22:36,000 --> 00:22:42,000
what that means is that not all the air traveling over the airplane goes at the same rate

383
00:22:42,000 --> 00:22:46,000
certain areas that actually travels a lot slower

384
00:22:46,000 --> 00:22:50,000
which creates a protective cushion where ice crystals can form

385
00:22:51,000 --> 00:22:53,000
this thing is like this big

386
00:22:53,000 --> 00:22:55,000
I call that baseball size right there

387
00:22:55,000 --> 00:22:59,000
if that whole thing broke off that would be just like the mid

388
00:22:59,000 --> 00:23:01,000
the guys are blown away

389
00:23:01,000 --> 00:23:03,000
unlike the ice

390
00:23:03,000 --> 00:23:07,000
question is how big can it get and will it fall off

391
00:23:08,000 --> 00:23:10,000
you can't believe how big it's getting

392
00:23:10,000 --> 00:23:13,000
20 minutes later with a diameter around 10 inches

393
00:23:13,000 --> 00:23:17,000
the blue icicles seems to have reached a size plateau

394
00:23:18,000 --> 00:23:20,000
it's approaching soccer ball size

395
00:23:20,000 --> 00:23:23,000
and with plenty of water still in the tank

396
00:23:23,000 --> 00:23:25,000
that's not the limiting factor

397
00:23:25,000 --> 00:23:28,000
but Grant thinks he knows what is

398
00:23:28,000 --> 00:23:30,000
now an interesting thing to note here

399
00:23:30,000 --> 00:23:33,000
is that as the ice is getting thicker and pushing away from the skin

400
00:23:33,000 --> 00:23:36,000
it's actually pushing its way out of the boundary layer

401
00:23:36,000 --> 00:23:38,000
once it exits the boundary layer

402
00:23:38,000 --> 00:23:41,000
it actually hits the fashion of moving air and just goes away

403
00:23:41,000 --> 00:23:43,000
it doesn't allow it to freeze up

404
00:23:43,000 --> 00:23:47,000
which may be a reason why the ice doesn't get really really big

405
00:23:47,000 --> 00:23:49,000
but let's see if we can get it to fall off

406
00:23:49,000 --> 00:23:51,000
let's pretend like it's at its final descent

407
00:23:51,000 --> 00:23:53,000
temperatures are rising

408
00:23:53,000 --> 00:23:56,000
maybe we can get it to break off and find out exactly what happens when it does

409
00:23:56,000 --> 00:23:58,000
perfect

410
00:23:58,000 --> 00:24:00,000
alright start warming it up

411
00:24:00,000 --> 00:24:03,000
it's a good theory because as the aircraft descends

412
00:24:03,000 --> 00:24:05,000
and the air temperature warms

413
00:24:06,000 --> 00:24:08,000
oh we're getting bigger chugs breaking off

414
00:24:08,000 --> 00:24:12,000
surely it's only a matter of time before the blue ice particle

415
00:24:12,000 --> 00:24:14,000
becomes a blue ice missile

416
00:24:14,000 --> 00:24:16,000
minus seven degrees

417
00:24:16,000 --> 00:24:20,000
and as it turns out when the wind tunnel conditions match those of an altitude of

418
00:24:20,000 --> 00:24:22,000
twelve thousand feet

419
00:24:22,000 --> 00:24:24,000
ohhhh

420
00:24:24,000 --> 00:24:26,000
we have lift off

421
00:24:26,000 --> 00:24:28,000
that's the blue up in one giant chunk

422
00:24:28,000 --> 00:24:30,000
wow

423
00:24:30,000 --> 00:24:32,000
that was perfect

424
00:24:32,000 --> 00:24:36,000
this myth is starting to look very very believable

425
00:24:36,000 --> 00:24:38,000
yeah but you know the next step is

426
00:24:38,000 --> 00:24:41,000
what happens to the ice after it falls off

427
00:24:41,000 --> 00:24:43,000
I can't believe it

428
00:24:43,000 --> 00:24:44,000
coming up later

429
00:24:44,000 --> 00:24:46,000
oh sh** we're burning this building down

430
00:24:50,000 --> 00:24:54,000
here's the story we're testing

431
00:24:54,000 --> 00:24:55,000
Jason Bourne

432
00:24:55,000 --> 00:24:56,000
knowing that the bad guys are coming

433
00:24:56,000 --> 00:24:59,000
wanting to buy himself a little extra time for the chase

434
00:24:59,000 --> 00:25:01,000
opens up the gas line

435
00:25:01,000 --> 00:25:03,000
of the house he's in

436
00:25:04,000 --> 00:25:06,000
walks over to a toaster

437
00:25:06,000 --> 00:25:09,000
grabs a magazine and sticks it in that toaster

438
00:25:09,000 --> 00:25:11,000
and sets it as a remote fuse

439
00:25:11,000 --> 00:25:13,000
and then he exits the house

440
00:25:14,000 --> 00:25:18,000
thirty seconds later a massive explosion

441
00:25:19,000 --> 00:25:21,000
gives him the lead time he's looking for

442
00:25:21,000 --> 00:25:23,000
now is that remotely plausible

443
00:25:23,000 --> 00:25:26,000
well those are the circumstances we've got set up in this house right here

444
00:25:26,000 --> 00:25:28,000
and that's going to be our first test

445
00:25:28,000 --> 00:25:31,000
in other words this test will be exactly like the movie

446
00:25:31,000 --> 00:25:33,000
but with one exception

447
00:25:34,000 --> 00:25:37,000
according to our testing it actually takes about two minutes

448
00:25:37,000 --> 00:25:40,000
for the toaster to set the magazine on fire

449
00:25:40,000 --> 00:25:42,000
so that means that we've had about

450
00:25:42,000 --> 00:25:45,000
four times the amount of gas going into the room

451
00:25:45,000 --> 00:25:48,000
and that two minutes is what Bourne had

452
00:25:48,000 --> 00:25:50,000
for the whole house to blow up

453
00:25:50,000 --> 00:25:52,000
now that two minutes in our case

454
00:25:52,000 --> 00:25:55,000
is only allowing about seven cubic feet of methane

455
00:25:55,000 --> 00:25:57,000
to go into the house

456
00:25:57,000 --> 00:25:59,000
and it's rising towards the roof

457
00:25:59,000 --> 00:26:03,000
meanwhile our source of ignition is about fifteen feet away

458
00:26:03,000 --> 00:26:06,000
I don't expect to see any kind of explosion at all

459
00:26:06,000 --> 00:26:08,000
and that's down to stoichiometry

460
00:26:08,000 --> 00:26:10,000
in theory for a room this size

461
00:26:10,000 --> 00:26:14,000
seven cubic feet of methane will be too low a concentration

462
00:26:14,000 --> 00:26:16,000
to ignite

463
00:26:16,000 --> 00:26:17,000
alright I'm ready

464
00:26:17,000 --> 00:26:19,000
okay Adam go ahead and turn on the gas

465
00:26:19,000 --> 00:26:20,000
copy that

466
00:26:20,000 --> 00:26:22,000
but this is Mythbusters

467
00:26:22,000 --> 00:26:24,000
and it's not a fact until you test it

468
00:26:25,000 --> 00:26:27,000
it's pretty eerie watching

469
00:26:27,000 --> 00:26:30,000
valuable gas go into a room in which we've started a fire

470
00:26:30,000 --> 00:26:32,000
or about to

471
00:26:35,000 --> 00:26:36,000
oh I see some fire

472
00:26:36,000 --> 00:26:38,000
fire great alright

473
00:26:38,000 --> 00:26:40,000
the magazine may finally be on fire

474
00:26:40,000 --> 00:26:42,000
but the methane is not igniting

475
00:26:42,000 --> 00:26:44,000
oh man that toaster is totally burning

476
00:26:44,000 --> 00:26:47,000
and even after a further sixty seconds

477
00:26:47,000 --> 00:26:50,000
there's still no hint of a Hollywood blast

478
00:26:50,000 --> 00:26:51,000
gas is off

479
00:26:51,000 --> 00:26:54,000
starting up the fans to evacuate the room

480
00:26:56,000 --> 00:26:57,000
that was cool

481
00:26:57,000 --> 00:26:58,000
that was very cool

482
00:26:58,000 --> 00:26:59,000
I was a little tense

483
00:26:59,000 --> 00:27:01,000
a flammable gas, a fire

484
00:27:01,000 --> 00:27:02,000
no boom

485
00:27:02,000 --> 00:27:03,000
no boom

486
00:27:03,000 --> 00:27:07,000
so it's time to send in the Mythbusters fire brigade

487
00:27:09,000 --> 00:27:10,000
oh yeah

488
00:27:12,000 --> 00:27:13,000
there's your problem

489
00:27:17,000 --> 00:27:21,000
so we replicated all the circumstances for Bourne's evasion technique

490
00:27:21,000 --> 00:27:22,000
and it totally didn't work

491
00:27:22,000 --> 00:27:25,000
I think that's a pretty clean busting of the myth

492
00:27:25,000 --> 00:27:26,000
yeah it's busted

493
00:27:26,000 --> 00:27:28,000
but you know I was thinking

494
00:27:28,000 --> 00:27:31,000
if we put something in that room that burned for longer

495
00:27:31,000 --> 00:27:33,000
eventually something's gonna happen

496
00:27:33,000 --> 00:27:37,000
you mean eventually the gas and the air will reach a mixture

497
00:27:37,000 --> 00:27:39,000
whereby we will get some kind of reaction

498
00:27:39,000 --> 00:27:40,000
yeah

499
00:27:40,000 --> 00:27:43,000
I love it I think that should be the next test

500
00:27:43,000 --> 00:27:45,000
although the exact circumstances of the movie

501
00:27:45,000 --> 00:27:47,000
won't get the bad guys off your tail

502
00:27:47,000 --> 00:27:50,000
the question is could a little more gas

503
00:27:50,000 --> 00:27:54,000
and a longer fuse get the big Bourne boom

504
00:27:54,000 --> 00:27:56,000
we know from our small scale testing in our research

505
00:27:56,000 --> 00:28:00,000
that it takes a minimum six percent fuel to air mix

506
00:28:00,000 --> 00:28:03,000
for methane and air to support ignition

507
00:28:03,000 --> 00:28:05,000
the way we've got it planned out

508
00:28:05,000 --> 00:28:07,000
if we take the contents of this methane tank

509
00:28:07,000 --> 00:28:09,000
and put it in our test room

510
00:28:09,000 --> 00:28:12,000
we'll have the right fuel air mix

511
00:28:12,000 --> 00:28:14,000
how are we gonna get a long burning open flame

512
00:28:14,000 --> 00:28:16,000
well we're throwing out the toaster in the magazine

513
00:28:16,000 --> 00:28:19,000
and we're going with a supermarket fireplace log

514
00:28:19,000 --> 00:28:22,000
light this puppy on fire it'll burn for at least an hour

515
00:28:22,000 --> 00:28:23,000
this is for real

516
00:28:23,000 --> 00:28:27,000
the log will burn while the gas builds to the six percent ratio

517
00:28:27,000 --> 00:28:28,000
that's it

518
00:28:28,000 --> 00:28:31,000
but when it hits the stoichiometric zone

519
00:28:31,000 --> 00:28:34,000
will they get the bad guy repelling detonation of the movie

520
00:28:35,000 --> 00:28:37,000
back in the safety of the bunker

521
00:28:37,000 --> 00:28:40,000
at first things go just as planned

522
00:28:40,000 --> 00:28:43,000
did you leave a log burning on the kitchen table

523
00:28:43,000 --> 00:28:45,000
aww crap I did

524
00:28:46,000 --> 00:28:50,000
but in a dramatic turn of events after four minutes

525
00:28:51,000 --> 00:28:52,000
oh you know what's happening

526
00:28:52,000 --> 00:28:56,000
the gas is actually making the whole room catch on fire

527
00:28:57,000 --> 00:28:59,000
things suddenly get in sendery

528
00:28:59,000 --> 00:29:01,000
I see smoke on the

529
00:29:01,000 --> 00:29:03,000
oh sh** we're burning this building down

530
00:29:03,000 --> 00:29:05,000
and out of control

531
00:29:09,000 --> 00:29:11,000
there we go we had a blowout

532
00:29:11,000 --> 00:29:13,000
that's it

533
00:29:18,000 --> 00:29:21,000
well I don't know if we're putting this building down

534
00:29:22,000 --> 00:29:24,000
oh we should get up there with the house

535
00:29:24,000 --> 00:29:26,000
alright let's turn off the gas

536
00:29:26,000 --> 00:29:27,000
gas is off

537
00:29:27,000 --> 00:29:30,000
the mythbusters initiate the safety protocols

538
00:29:30,000 --> 00:29:33,000
and cautiously approach their apartment inferno

539
00:29:33,000 --> 00:29:34,000
don't go in

540
00:29:34,000 --> 00:29:36,000
I'm not seeing any flame

541
00:29:37,000 --> 00:29:38,000
there's the hole we blew

542
00:29:38,000 --> 00:29:41,000
it may not have been the blast of the movie

543
00:29:41,000 --> 00:29:42,000
it's a horch open there

544
00:29:42,000 --> 00:29:45,000
but the methane sure made a mess of the apartment

545
00:29:45,000 --> 00:29:48,000
so all of a sudden the fire is going up and reaching the ceiling

546
00:29:48,000 --> 00:29:50,000
there's smoke coming out of the top

547
00:29:50,000 --> 00:29:53,000
and then the mixture hit the bottom of the stoichiometric range

548
00:29:53,000 --> 00:29:54,000
and we saw this

549
00:29:54,000 --> 00:29:55,000
whooow

550
00:29:55,000 --> 00:29:57,000
across the whole room

551
00:29:58,000 --> 00:30:00,000
I'm seeing broken glass on a bunch of windows

552
00:30:00,000 --> 00:30:01,000
on the back double doors

553
00:30:01,000 --> 00:30:04,000
it's clear that we got a significant reaction

554
00:30:04,000 --> 00:30:06,000
but nothing close to what we saw in the movie

555
00:30:07,000 --> 00:30:09,000
nothing close to a caboo

556
00:30:09,000 --> 00:30:11,000
but certainly enough of a conflagration

557
00:30:11,000 --> 00:30:13,000
to distract the bad guys

558
00:30:14,000 --> 00:30:17,000
it's really clear from all the melted plastic in there

559
00:30:17,000 --> 00:30:18,000
and even our exhaust fans melted

560
00:30:18,000 --> 00:30:21,000
it got super crazy hot in there

561
00:30:21,000 --> 00:30:22,000
very quickly

562
00:30:22,000 --> 00:30:24,000
I mean just the whole room was absolute

563
00:30:24,000 --> 00:30:26,000
I didn't even know what temperature it could be at

564
00:30:26,000 --> 00:30:27,000
but it was really hot

565
00:30:27,000 --> 00:30:29,000
but you know we're not going to leave it there

566
00:30:29,000 --> 00:30:30,000
no, no

567
00:30:33,000 --> 00:30:34,000
next

568
00:30:34,000 --> 00:30:36,000
I think Carrie's going to scream her head off

569
00:30:36,000 --> 00:30:38,000
she may potentially pee her suit

570
00:30:38,000 --> 00:30:41,000
but I think that block of ice is going to land on the ground in one big chunk

571
00:30:46,000 --> 00:30:47,000
so here's where we're at

572
00:30:47,000 --> 00:30:49,000
we've looked into airline toilets

573
00:30:49,000 --> 00:30:51,000
and found that they can leak through an external fowl

574
00:30:51,000 --> 00:30:52,000
is it possible?

575
00:30:52,000 --> 00:30:53,000
absolutely

576
00:30:53,000 --> 00:30:54,000
we made our own fuselage

577
00:30:54,000 --> 00:30:56,000
went to NASA's wind tunnel

578
00:30:56,000 --> 00:30:59,000
and found that you could actually form a giant chunk of ice

579
00:30:59,000 --> 00:31:01,000
which then fell off the airplane

580
00:31:04,000 --> 00:31:08,000
now we're going to test what happens to that ice after it falls

581
00:31:08,000 --> 00:31:11,000
what we need to see for this myth to be confirmed

582
00:31:11,000 --> 00:31:14,000
is for that ice to fall through the air as one giant chuck

583
00:31:14,000 --> 00:31:18,000
and hit the ground as one piece with deadly force

584
00:31:19,000 --> 00:31:22,000
this is the final piece of the blue ice puzzle

585
00:31:22,000 --> 00:31:28,000
while falling from 12,000 feet at a terminal velocity of 160 miles per hour

586
00:31:28,000 --> 00:31:30,000
will the ice stay in one piece

587
00:31:30,000 --> 00:31:36,000
or will wind erosion and warming temperatures cause it to break up into harmless blue rain

588
00:31:39,000 --> 00:31:42,000
to track that, the team has a spectacular plan of action

589
00:31:43,000 --> 00:31:47,000
we have our airplane, we're going to load it up with a large chunk of ice

590
00:31:47,000 --> 00:31:49,000
take it up to altitude and then throw it out

591
00:31:49,000 --> 00:31:52,000
now we're going to have a few skydivers jump out with the ice to track

592
00:31:52,000 --> 00:31:55,000
Kerry is going to be one of those skydivers

593
00:31:55,000 --> 00:32:00,000
yep, and skydiving team leader Nick also has the crucial job of timing the drop

594
00:32:00,000 --> 00:32:04,000
because if the myth is true and the blue ice falls in one chunk

595
00:32:04,000 --> 00:32:06,000
missing the mark could be deadly

596
00:32:06,000 --> 00:32:08,000
that's something you can see there

597
00:32:09,000 --> 00:32:10,000
okay so here's the plan

598
00:32:10,000 --> 00:32:13,000
Kerry and our expert Nick will go in the plane with the ice

599
00:32:13,000 --> 00:32:16,000
they're going to go up and based on the prevailing conditions

600
00:32:16,000 --> 00:32:19,000
and Nick's calculations they'll know when to release the ice

601
00:32:19,000 --> 00:32:22,000
at an altitude that they deem safe

602
00:32:22,000 --> 00:32:26,000
Nick will jump out and so will Kerry following the ice down

603
00:32:26,000 --> 00:32:28,000
do we fine

604
00:32:29,000 --> 00:32:30,000
I'm going to double check this

605
00:32:31,000 --> 00:32:35,000
meanwhile Tori and I will be on the ground tracking the ice in the air

606
00:32:35,000 --> 00:32:37,000
and looking for the impact zone

607
00:32:37,000 --> 00:32:39,000
and as for the blue ice

608
00:32:39,000 --> 00:32:43,000
well earlier Kerry prepared a similar size block to the test at NASA

609
00:32:43,000 --> 00:32:49,000
it's approximately the diameter of a basketball, eye catching and easily retrievable

610
00:32:49,000 --> 00:32:52,000
to make sure that we can watch this ice fall

611
00:32:52,000 --> 00:32:54,000
I've done something a little different

612
00:32:54,000 --> 00:32:58,000
I've made it red instead of blue so that it's going to stand out on the blue sky

613
00:32:58,000 --> 00:33:01,000
I've added some really long streamers so that we can track it

614
00:33:01,000 --> 00:33:03,000
and I'm going to put a GPS on it

615
00:33:04,000 --> 00:33:07,000
now for this myth to be confirmed we need to see that block of ice

616
00:33:07,000 --> 00:33:12,000
drop from altitude and get to the earth in one solid chunk

617
00:33:13,000 --> 00:33:15,000
good luck, good luck you guys

618
00:33:15,000 --> 00:33:17,000
what I think is going to happen

619
00:33:17,000 --> 00:33:19,000
I think Kerry is going to scream her head off

620
00:33:19,000 --> 00:33:21,000
she may potentially pee her suit

621
00:33:21,000 --> 00:33:25,000
but I think that block of ice is going to land on the ground in one big chunk

622
00:33:25,000 --> 00:33:27,000
okay here's the package

623
00:33:27,000 --> 00:33:29,000
good luck

624
00:33:30,000 --> 00:33:34,000
and despite all of their precautions they will need some luck

625
00:33:34,000 --> 00:33:38,000
their goal is to drop the ice and Kerry from 12,000 feet

626
00:33:38,000 --> 00:33:40,000
here we go Kerry

627
00:33:40,000 --> 00:33:45,000
the height at which Grant and Tori saw the ice release from the fuselage at NASA

628
00:33:45,000 --> 00:33:50,000
okay now I'm starting to get a little nervous

629
00:33:50,000 --> 00:33:52,000
but will it remain intact

630
00:33:52,000 --> 00:33:56,000
traveling with an energy of 392,000 joules

631
00:33:56,000 --> 00:33:59,000
its impact will certainly be deadly

632
00:33:59,000 --> 00:34:05,000
however if it melts in the rising temperatures it'll be rendered harmless

633
00:34:06,000 --> 00:34:10,000
after the break the mythbusters touch down for blue ice

634
00:34:10,000 --> 00:34:13,000
wow nice

635
00:34:13,000 --> 00:34:16,000
and can Adam and Jamie get a big born move

636
00:34:23,000 --> 00:34:30,000
at 12,000 feet Kerry and her free falling friends are preparing to deploy their blue ice cargo

637
00:34:30,000 --> 00:34:33,000
all I gotta do is look at the ice one job

638
00:34:33,000 --> 00:34:35,000
but will it break up on descent

639
00:34:35,000 --> 00:34:39,000
or have the devastating impact internet reports claim

640
00:34:43,000 --> 00:34:47,000
if the team misjudged the timing of the drop by even a second

641
00:34:47,000 --> 00:34:54,000
a 35 pound projectile traveling at 160 miles per hour could crash through a neighboring house

642
00:34:55,000 --> 00:34:59,000
but that's only if the ice actually stays in one chunk

643
00:34:59,000 --> 00:35:03,000
if it breaks up the only thing busted will be the myth

644
00:35:05,000 --> 00:35:08,000
I've got them there approaching the drop zone

645
00:35:08,000 --> 00:35:13,000
so this is it it's time to drop out and jump off for science

646
00:35:18,000 --> 00:35:20,000
okay the ice is away

647
00:35:24,000 --> 00:35:26,000
ah what's over there

648
00:35:29,000 --> 00:35:35,000
in a stunning piece of free fall camera work Nick manages to capture the ice as it plumps

649
00:35:37,000 --> 00:35:40,000
look how fast this falling is falling

650
00:35:40,000 --> 00:35:43,000
and Kerry can see that it's so far so good

651
00:35:43,000 --> 00:35:48,000
with the ice already at a balmy 5,000 feet it's still completely in jack

652
00:35:50,000 --> 00:35:54,000
look it's standing in one chunk dude that's crazy

653
00:35:54,000 --> 00:35:59,000
but will it stay that way as they enter the final few thousand feet of descent

654
00:35:59,000 --> 00:36:03,000
the TBI is right there and it's at near the target that's great

655
00:36:07,000 --> 00:36:09,000
wow

656
00:36:09,000 --> 00:36:11,000
do you see the size of that impact

657
00:36:11,000 --> 00:36:13,000
and did you see it stay in one chunk

658
00:36:13,000 --> 00:36:17,000
wow that's maybe only 150 feet from the drop zone

659
00:36:17,000 --> 00:36:21,000
I felt the ice going down which is weird exactly and it stayed intact

660
00:36:21,000 --> 00:36:23,000
let's go meet Kerry and we'll go find it

661
00:36:23,000 --> 00:36:25,000
alright let's go get him

662
00:36:25,000 --> 00:36:27,000
hi Kerry

663
00:36:27,000 --> 00:36:28,000
hi Grant

664
00:36:28,000 --> 00:36:29,000
here she goes

665
00:36:29,000 --> 00:36:31,000
she's coming in hot

666
00:36:32,000 --> 00:36:33,000
you made it

667
00:36:33,000 --> 00:36:35,000
wow

668
00:36:35,000 --> 00:36:36,000
nice

669
00:36:38,000 --> 00:36:41,000
what a ride and what a test

670
00:36:41,000 --> 00:36:44,000
and no wonder Kerry's adrenaline is off the charts

671
00:36:44,000 --> 00:36:46,000
let's go check out the ice did you see it

672
00:36:46,000 --> 00:36:48,000
yeah yeah I don't

673
00:36:48,000 --> 00:36:52,000
everything went according to plan for the majority of its descent

674
00:36:52,000 --> 00:36:57,000
there was visual contact confirming that the ice retained its shape and mass

675
00:36:57,000 --> 00:37:00,000
and then thanks to Kerry's visual aids

676
00:37:01,000 --> 00:37:06,000
and Nick's awesome aim finding the impact site is a breeze

677
00:37:06,000 --> 00:37:08,000
there's the streamer

678
00:37:08,000 --> 00:37:09,000
is it intact

679
00:37:09,000 --> 00:37:11,000
I mean it was a chunk before it hit the ground

680
00:37:11,000 --> 00:37:13,000
and that is still a chunk of ice

681
00:37:13,000 --> 00:37:17,000
check it out it dug itself into the ground

682
00:37:17,000 --> 00:37:19,000
that is a serious impact

683
00:37:19,000 --> 00:37:23,000
yep and it may have melted slightly in the time it took to find it

684
00:37:23,000 --> 00:37:27,000
but the crater created is a clear testament to its destructive power

685
00:37:28,000 --> 00:37:32,000
this is the size of the block of ice that we threw out of our plane

686
00:37:32,000 --> 00:37:37,000
which is very similar to the size of the chunk of ice that we formed in our wind tunnel at NASA

687
00:37:37,000 --> 00:37:38,000
that fell off

688
00:37:38,000 --> 00:37:42,000
that block of ice reached term of velocity very quickly

689
00:37:42,000 --> 00:37:44,000
it left a sizable impact crater

690
00:37:44,000 --> 00:37:49,000
what's more it stayed pretty much intact all the way down to impact

691
00:37:49,000 --> 00:37:53,000
okay a pilot can't release all of the toilet water once so that part's busted

692
00:37:53,000 --> 00:37:55,000
but I think the phenomena is confirmed

693
00:37:55,000 --> 00:37:57,000
I mean it made it all the way to the ground

694
00:37:57,000 --> 00:37:58,000
totally confirmed

695
00:37:58,000 --> 00:37:59,000
I agree 100%

696
00:37:59,000 --> 00:38:05,000
confirmed but three mechanical failures leading to blue ice falling on your house

697
00:38:05,000 --> 00:38:08,000
is in reality incredibly unlikely

698
00:38:09,000 --> 00:38:14,000
I don't want to be looking up for blue ice to fall in my head now right

699
00:38:14,000 --> 00:38:16,000
dude I'm gonna get blue ice insurance

700
00:38:16,000 --> 00:38:17,000
I know a guy

701
00:38:17,000 --> 00:38:18,000
yeah

702
00:38:18,000 --> 00:38:19,000
let me know I'll give you his number

703
00:38:25,000 --> 00:38:29,000
at the Mythbusters mansion they've been renovating foreign style

704
00:38:29,000 --> 00:38:30,000
don't move

705
00:38:30,000 --> 00:38:34,000
however the myth as it appears in the movie is busted

706
00:38:34,000 --> 00:38:35,000
uh oh

707
00:38:36,000 --> 00:38:40,000
but it ain't over until the man in the beret gets a big born boom

708
00:38:40,000 --> 00:38:44,000
so next they're upping the adi with more gas

709
00:38:44,000 --> 00:38:49,000
now when we empty this tank into that house that means that we'll have just over 9%

710
00:38:49,000 --> 00:38:51,000
methane to air in there

711
00:38:51,000 --> 00:38:54,000
and that happens to be the butter zone for an explosion

712
00:38:54,000 --> 00:38:59,000
the guys know from small scale that 9% netted them the most energetic boom

713
00:38:59,000 --> 00:39:01,000
but this is large scale

714
00:39:01,000 --> 00:39:05,000
will this test rip apart the apartment born style

715
00:39:05,000 --> 00:39:08,000
before they blow it up they need to spruce it up

716
00:39:08,000 --> 00:39:11,000
we've swapped out all the windows and doors

717
00:39:11,000 --> 00:39:14,000
all these holes that got warped and opened

718
00:39:14,000 --> 00:39:16,000
we're gonna actually lay in a bunch of stripping

719
00:39:16,000 --> 00:39:20,000
we probably tripled the cohesive strength of this building

720
00:39:20,000 --> 00:39:23,000
and that ought to give us just the boom we're looking for

721
00:39:24,000 --> 00:39:26,000
Jamie's known for how he handles his fans

722
00:39:27,000 --> 00:39:31,000
this time around I'm running the methane into the house through this hose

723
00:39:31,000 --> 00:39:35,000
that I've attached to the floor and I've drilled a lot of little holes in the hose

724
00:39:35,000 --> 00:39:42,000
so that we'll get these jets of gas coming out that will mix with the air that is being pushed across them with these fans

725
00:39:42,000 --> 00:39:44,000
kind of like a blender

726
00:39:44,000 --> 00:39:46,000
this mix the air all of

727
00:39:46,000 --> 00:39:47,000
yeah

728
00:39:47,000 --> 00:39:53,000
this swirling mass of air I'm hoping will distribute this fuel air mix throughout the room

729
00:39:53,000 --> 00:39:57,000
and hopefully that'll make the difference between a poof and a bang

730
00:39:57,000 --> 00:40:01,000
Jamie's fantastic method will circulate the methane throughout the apartment

731
00:40:01,000 --> 00:40:05,000
and with the dangerous ratio of 9% gas to air

732
00:40:05,000 --> 00:40:09,000
they'll need something more sophisticated for ignition

733
00:40:09,000 --> 00:40:12,000
we brought back out the neon transformer from the small scale testing

734
00:40:12,000 --> 00:40:14,000
with the addition of a little piece of paper here

735
00:40:14,000 --> 00:40:16,000
go ahead and plug it in

736
00:40:16,000 --> 00:40:20,000
we're gonna be able to set a fire exactly when we want to set a fire

737
00:40:20,000 --> 00:40:25,000
exactly when they achieve the Goldilocks ratio of 9% methane to air

738
00:40:25,000 --> 00:40:30,000
fans are rolling that's the last piece of the puzzle shall we get to a safe place and go boom

739
00:40:30,000 --> 00:40:32,000
yeah awesome

740
00:40:33,000 --> 00:40:35,000
let's turn on the gas

741
00:40:35,000 --> 00:40:36,000
okie dokie

742
00:40:36,000 --> 00:40:38,000
alright we got about five minutes let's get to the bunker

743
00:40:40,000 --> 00:40:42,000
fire in the hole

744
00:40:43,000 --> 00:40:44,000
hopefully

745
00:40:44,000 --> 00:40:46,000
actually I think they need a new signal for us it'd be like

746
00:40:46,000 --> 00:40:48,000
fire in the hole

747
00:40:48,000 --> 00:40:49,000
hopefully

748
00:40:49,000 --> 00:40:55,000
hopefully is right the precise stoichiometric ratio should be enough to detonate their apartment

749
00:40:55,000 --> 00:40:59,000
so our fire starters take cover as the methane fills the room

750
00:40:59,000 --> 00:41:05,000
we're down below 20 cubic feet per minute and we're about 100 psi

751
00:41:05,000 --> 00:41:09,000
so I'm thinking we should go whenever you're ready

752
00:41:09,000 --> 00:41:16,000
with the room filled with 9% methane will this finally yield the Hollywood blowout

753
00:41:16,000 --> 00:41:23,000
alright here we go ideal gas air mixture born explosion in 3, 2, 1

754
00:41:24,000 --> 00:41:26,000
oh yeah

755
00:41:33,000 --> 00:41:35,000
that is awesome

756
00:41:35,000 --> 00:41:37,000
we blew out the whole front

757
00:41:37,000 --> 00:41:38,000
yeah

758
00:41:38,000 --> 00:41:40,000
we couldn't have done that if we planned

759
00:41:40,000 --> 00:41:41,000
that was perfect

760
00:41:41,000 --> 00:41:42,000
hahaha

761
00:41:42,000 --> 00:41:44,000
and there you have it

762
00:41:45,000 --> 00:41:49,000
one magnificent made to order apartment explosion

763
00:41:53,000 --> 00:41:58,000
but unlike the movie detonation this one is polite enough to put itself out

764
00:41:58,000 --> 00:42:00,000
well almost

765
00:42:00,000 --> 00:42:06,000
I hope this is a cautionary tale what happens when you mix mythbusters with science

766
00:42:06,000 --> 00:42:11,000
okay here's the thing while that was fairly exciting I mean we blew out the wall

767
00:42:11,000 --> 00:42:16,000
I want to point out that we didn't break any glass there was no bang it was a whoosh

768
00:42:16,000 --> 00:42:19,000
and that's something entirely different than what we saw in the movie

769
00:42:19,000 --> 00:42:26,000
the fact that this was an ideally mixed mixture with fans and everything in the exact quantity

770
00:42:26,000 --> 00:42:28,000
and that's the best we could do

771
00:42:28,000 --> 00:42:30,000
kind of like a real fire

772
00:42:30,000 --> 00:42:33,000
clearly we were born for this job

773
00:42:33,000 --> 00:42:37,000
haha yeah but it's kind of too bad that was a nice view in that house
