00:00:00,000 --> 00:00:09,160
On this episode of MythBusters, our ally bombers wrecking your dreams of world domination.

2
00:00:09,160 --> 00:00:14,720
Adam and Jamie make alternate history as they go back in time to recreate an attempt to

3
00:00:14,720 --> 00:00:15,720
assassinate Hitler.

4
00:00:15,720 --> 00:00:17,720
I wouldn't want to be in that room.

5
00:00:17,720 --> 00:00:18,720
No, I wouldn't want to be in that room.

6
00:00:18,720 --> 00:00:24,360
Was a room change the reason this bomb in a briefcase failed first time around?

7
00:00:24,360 --> 00:00:25,360
Peter's aim.

8
00:00:26,360 --> 00:00:27,360
Meantime.

9
00:00:27,360 --> 00:00:28,360
Sorry, Carrie.

10
00:00:28,360 --> 00:00:30,360
Carrie, Tori and Grant.

11
00:00:30,360 --> 00:00:31,360
Here we go.

12
00:00:31,360 --> 00:00:33,360
All take one for the team.

13
00:00:33,360 --> 00:00:34,360
How do you feel?

14
00:00:34,360 --> 00:00:35,360
A little more alert?

15
00:00:35,360 --> 00:00:40,360
As they test out the myth that you really can slap sense into someone.

16
00:00:40,360 --> 00:00:43,360
This myth sucks.

17
00:00:46,360 --> 00:00:47,360
Who are the MythBusters?

18
00:00:47,360 --> 00:00:48,360
Carrie.

19
00:00:48,360 --> 00:00:49,360
Adam Savage.

20
00:00:49,360 --> 00:00:51,360
70% chance of science.

21
00:00:51,360 --> 00:00:53,360
And Jamie Heinemann.

22
00:00:54,360 --> 00:01:01,360
Between them more than 30 years of special effects experience, joining them, Tori Bellachy.

23
00:01:01,360 --> 00:01:03,360
Oh, they're going to fry my brain.

24
00:01:03,360 --> 00:01:04,360
Grant Imahara.

25
00:01:04,360 --> 00:01:06,360
And Carrie Byron.

26
00:01:06,360 --> 00:01:09,360
Science gets more fun when I get a bigger gun.

27
00:01:09,360 --> 00:01:11,360
They don't just tell the myths.

28
00:01:11,360 --> 00:01:14,360
They put them to the test.

29
00:01:24,360 --> 00:01:28,360
In 1944, a plot was hatched to kill Hitler.

30
00:01:28,360 --> 00:01:36,360
And the operation was successful enough to actually get a briefcase full of explosives into a room with Hitler and detonate it while Hitler was in the room.

31
00:01:36,360 --> 00:01:37,360
Okay.

32
00:01:37,360 --> 00:01:41,360
But the operation was a failure because Hitler did not die in that blast.

33
00:01:41,360 --> 00:01:43,360
So what went wrong?

34
00:01:43,360 --> 00:01:44,360
Here's the wrinkle.

35
00:01:44,360 --> 00:01:48,360
The meeting was originally supposed to happen in a closed underground bunker.

36
00:01:48,360 --> 00:01:58,360
But at the last minute, the meeting place was switched to an above ground room with open windows and conventional wisdom holds that that same blast would have killed Hitler if it had happened in the closed bunker room.

37
00:01:58,360 --> 00:01:59,360
Nice.

38
00:01:59,360 --> 00:02:02,360
A little blast from the past, so to speak.

39
00:02:18,360 --> 00:02:22,360
In the conference room, above ground, with conventional doors and windows.

40
00:02:22,360 --> 00:02:28,360
Four people were killed in the blast, but Hitler survived with just minor injuries.

41
00:02:28,360 --> 00:02:37,360
There are dozens of theories about what went wrong, but the biggest is that it was the change of venue that turned the bomb from lethal to survivable.

42
00:02:37,360 --> 00:02:41,360
So this myth is a tale of two rooms.

43
00:02:41,360 --> 00:02:49,360
The question here boils down to whether or not an explosion going off in an enclosed space is inherently more deadly than one going off in an open space, right?

44
00:02:49,360 --> 00:02:50,360
Exactly.

45
00:02:50,360 --> 00:02:52,360
Where do you think we should begin?

46
00:02:52,360 --> 00:02:55,360
Well, let's do some research and then start small and work our way up.

47
00:02:55,360 --> 00:02:56,360
Perfect.

48
00:02:56,360 --> 00:03:08,360
History books are helpful, but Jamie's gone the extra mile and sourced actual Nazi photos of the damage incurred in the blast of July 20, 1944.

49
00:03:08,360 --> 00:03:13,360
What all these photos of the situation room tell me is that the blast was actually quite severe.

50
00:03:13,360 --> 00:03:24,360
And given the fact that Hitler was standing here when the bomb was right nearby and four people actually did die from the blast, Hitler really narrowly escaped death.

51
00:03:24,360 --> 00:03:29,360
While Jamie pours over the details, Adam pours paint in a tub full of water.

52
00:03:29,360 --> 00:03:36,360
It's a simple experiment that should show what happens when shock waves are contained or released.

53
00:03:36,360 --> 00:03:39,360
All he needs now is to model rooms.

54
00:03:39,360 --> 00:03:46,360
Now, why is the conventional wisdom that the explosion that did not kill Hitler in the room with windows would have killed him in the bunker?

55
00:03:46,360 --> 00:03:54,360
I'm hoping to tease out the reasons for that thinking with this visualization before me, the four walls of the bunker.

56
00:03:54,360 --> 00:03:57,360
I'm going to drop this little weight into the center.

57
00:03:57,360 --> 00:03:58,360
Let's see what happens.

58
00:03:58,360 --> 00:04:03,360
Let's look at the high speed.

59
00:04:03,360 --> 00:04:10,360
The idea is that the ripples or waves of water behave much like a percussive blast through air.

60
00:04:10,360 --> 00:04:11,360
Awesome.

61
00:04:11,360 --> 00:04:15,360
My visualization of waves in a closed room worked just the way I hoped.

62
00:04:15,360 --> 00:04:20,360
You can see the waves traveling out from the way that I dropped, hitting the walls and then bouncing back.

63
00:04:20,360 --> 00:04:22,360
They've got nowhere to go.

64
00:04:22,360 --> 00:04:27,360
Now, to see if throwing open a few windows really makes much of a difference.

65
00:04:27,360 --> 00:04:29,360
Alright, so this is my situation room.

66
00:04:29,360 --> 00:04:32,360
Each of these spaces is an open window.

67
00:04:32,360 --> 00:04:34,360
Here is my bomb.

68
00:04:34,360 --> 00:04:37,360
Let's see what happens.

69
00:04:39,360 --> 00:04:41,360
Perfect.

70
00:04:41,360 --> 00:04:44,360
The high speed confirms what Adam suspected.

71
00:04:44,360 --> 00:04:45,360
That is so cool.

72
00:04:45,360 --> 00:04:48,360
Give a wave half a chance to escape and it takes it.

73
00:04:48,360 --> 00:04:50,360
So what can we surmise from this?

74
00:04:50,360 --> 00:04:53,360
We can clearly see in the closed room the waves are contained.

75
00:04:53,360 --> 00:04:58,360
They do not escape and we can see in the open room with windows that the waves totally get out.

76
00:04:58,360 --> 00:05:01,360
So it looks like there's some science to back up the myth.

77
00:05:01,360 --> 00:05:08,360
Back at Allied headquarters, Jamie's now gotten his hands on the official Gestapo report of the bombing.

78
00:05:08,360 --> 00:05:16,360
Upper pressure wave destroyed the situation room to a large extent and exited through windows and doors as well as through partition walls.

79
00:05:16,360 --> 00:05:22,360
Points of impact of metal fragments not detectable, but splinters of wood and leather fragments are embedded into the wood.

80
00:05:22,360 --> 00:05:29,360
The furor suffered only slight injuries although in the immediate vicinity of the center of the explosion.

81
00:05:29,360 --> 00:05:34,360
So the facts and the photos are all duly noted for future comparison.

82
00:05:34,360 --> 00:05:38,360
Now you'd have to agree that it's high time they blew something up.

83
00:05:44,360 --> 00:05:47,360
Okay, this is going to hurt me more than it hurts you.

84
00:05:47,360 --> 00:05:49,360
Ow, you're right, that did hurt.

85
00:05:49,360 --> 00:05:51,360
Ow, what was that for?

86
00:05:51,360 --> 00:05:55,360
I'm repairing you for the next myth, which is that you can slap sense into someone.

87
00:05:55,360 --> 00:05:56,360
Oh no.

88
00:05:56,360 --> 00:06:06,360
Oh yes, the idea is that if someone's in a state of confusion or shock, by slapping them, you can get them to focus, hone in their senses and perform better.

89
00:06:08,360 --> 00:06:11,360
It's a familiar scene from old school Hollywood.

90
00:06:11,360 --> 00:06:16,360
Someone flips out, good sharp slap brings them right back around.

91
00:06:16,360 --> 00:06:20,360
It kind of makes sense, what with the shock and the sting.

92
00:06:20,360 --> 00:06:22,360
But, does it work?

93
00:06:22,360 --> 00:06:27,360
When I think about this saying, I think about someone who's hysterical, who's on the edge of panic.

94
00:06:27,360 --> 00:06:29,360
How are we going to induce panic in each other?

95
00:06:29,360 --> 00:06:37,360
I'm not sure we have to. I mean, I'd like to talk to a trauma expert and find out if there's a way to inhibit the brain, something similar to panic, but a lot easier to achieve.

96
00:06:37,360 --> 00:06:43,360
Alright, as far as the testing goes, the pre-slap and the post-slap tests, they have to be a decision-making test.

97
00:06:43,360 --> 00:06:47,360
Because we're not testing IQ here, we're testing how you make decisions under pressure.

98
00:06:47,360 --> 00:06:49,360
Exactly, totally agree.

99
00:06:49,360 --> 00:06:55,360
First up, Carrie takes counsel to learn how the body responds to a smack in the chops.

100
00:06:55,360 --> 00:06:58,360
So what do you think of the myth that you can slap sense into someone?

101
00:06:58,360 --> 00:07:03,360
Well, a multiple things happen simultaneously with Carrie with the intense stimulation.

102
00:07:03,360 --> 00:07:11,360
You have a signal going from your face to the brain, which then sends a signal to the adrenal gland, which secretes epinephrine.

103
00:07:11,360 --> 00:07:14,360
This triggers the fight or flight reflex.

104
00:07:14,360 --> 00:07:18,360
You get an immediate blood flow increase to those vital organs.

105
00:07:18,360 --> 00:07:22,360
Your eyes widely dilate so you get clear and increased vision.

106
00:07:22,360 --> 00:07:27,360
So you're ready to make a decision, you can think clearer, and you can fight or you can flee.

107
00:07:27,360 --> 00:07:33,360
The only fight or flight response isn't exactly unknown here at Mythbusters.

108
00:07:33,360 --> 00:07:36,360
When in peril, I will use one of my coworkers as a human shield.

109
00:07:36,360 --> 00:07:42,360
But how can the guys induce something akin to a sense of panic in order to test out the myth?

110
00:07:42,360 --> 00:07:45,360
Well, you know, there could be a variety of tests.

111
00:07:45,360 --> 00:07:52,360
So if someone is compromised in some way and people can be compromised from hypothermia or hypothermia, a variety of sources.

112
00:07:52,360 --> 00:07:57,360
But to test that, you'd want to find some fine psychomotor skill.

113
00:07:57,360 --> 00:08:01,360
Back at the shop, Grant and Tory are welding up a storm.

114
00:08:01,360 --> 00:08:07,360
They're determined to take the human factor out of the equation by scratch building a face-slapping robot.

115
00:08:07,360 --> 00:08:10,360
We have a bungee cord that's attached here. It'll wrap around this rod.

116
00:08:10,360 --> 00:08:12,360
Now we'll wind up the arm and then release it.

117
00:08:12,360 --> 00:08:15,360
You don't want to use motors or pistons because let's face it.

118
00:08:15,360 --> 00:08:18,360
We're going to be putting our faces in the way of this slapping hand.

119
00:08:18,360 --> 00:08:20,360
We want slaps, not broken jaws.

120
00:08:20,360 --> 00:08:24,360
All this mechanical marvel is missing is a hand to hit with.

121
00:08:24,360 --> 00:08:28,360
So they'll fashion a surrogate forearm from carries.

122
00:08:28,360 --> 00:08:30,360
Deceivingly hairy arms.

123
00:08:30,360 --> 00:08:33,360
They're not hairy. It's like baby down.

124
00:08:33,360 --> 00:08:36,360
It's a process Tory's almost perfected.

125
00:08:36,360 --> 00:08:46,360
The limb gets shaved, greased, and plastered with dental alginate, which eventually sets to make a mold.

126
00:08:46,360 --> 00:08:54,360
In this case, the mold is filled with silicone and when that sets, they can arm the robot.

127
00:08:54,360 --> 00:08:58,360
Oh, goodness. Here, Tory.

128
00:08:58,360 --> 00:09:02,360
But before we do that, we need to find out how hard we slap.

129
00:09:02,360 --> 00:09:03,360
And that's where this guy comes in.

130
00:09:03,360 --> 00:09:09,360
We're going to slap the force plate, record the data, and use that information to calibrate our machine.

131
00:09:09,360 --> 00:09:11,360
Grant strikes first.

132
00:09:11,360 --> 00:09:14,360
It's going to hurt you more than it hurts me.

133
00:09:14,360 --> 00:09:16,360
Then Tory.

134
00:09:16,360 --> 00:09:18,360
All right, ready when you are.

135
00:09:18,360 --> 00:09:20,360
They look more like a spank.

136
00:09:20,360 --> 00:09:22,360
And then Carrie steps up to the plate.

137
00:09:22,360 --> 00:09:26,360
Now remember, however hard you slap that thing is how hard you're going to get slapped.

138
00:09:26,360 --> 00:09:29,360
This myth sucks. All right.

139
00:09:29,360 --> 00:09:32,360
Oh, maybe that was too hard. Maybe that was too hard.

140
00:09:32,360 --> 00:09:36,360
Maybe it was, but Grant's in no mood for a do-over.

141
00:09:36,360 --> 00:09:38,360
Okay, so Carrie, you hit with 94.

142
00:09:38,360 --> 00:09:42,360
I hit with 114 and Tory, you hit with 116.

143
00:09:42,360 --> 00:09:47,360
So our average is 108 pounds. That's our target.

144
00:09:47,360 --> 00:09:52,360
It's no comfort to Carrie to know that the hand set to strike is more or less hers.

145
00:09:52,360 --> 00:09:56,360
It's like I picked my own switch off the tree to get spanked with.

146
00:09:56,360 --> 00:09:58,360
All right, Carrie, you ready?

147
00:09:58,360 --> 00:10:01,360
I take no pleasure in this whatsoever.

148
00:10:01,360 --> 00:10:02,360
Oh my God.

149
00:10:02,360 --> 00:10:05,360
In three, two, one.

150
00:10:07,360 --> 00:10:09,360
Hit a little high.

151
00:10:09,360 --> 00:10:11,360
It was the comeback that I think...

152
00:10:11,360 --> 00:10:13,360
They get you out.

153
00:10:13,360 --> 00:10:19,360
The aim was a ride, but so far the mechanical slap looks right on the money.

154
00:10:20,360 --> 00:10:22,360
Carrie's followed by Grant.

155
00:10:22,360 --> 00:10:23,360
One.

156
00:10:27,360 --> 00:10:28,360
And then Tory.

157
00:10:30,360 --> 00:10:32,360
That is really good.

158
00:10:32,360 --> 00:10:36,360
So what do you think? Is that... I think it's perfect because it gives you just enough shock.

159
00:10:36,360 --> 00:10:38,360
It doesn't like knock you out.

160
00:10:38,360 --> 00:10:40,360
And that's just what they wanted.

161
00:10:40,360 --> 00:10:44,360
The next step is impairing their brains before slapping.

162
00:10:44,360 --> 00:10:48,360
So one thing we know is there's more pain to come.

163
00:10:49,360 --> 00:10:54,360
After the break, Adam and Jamie put their theories into practice.

164
00:10:54,360 --> 00:10:57,360
Three, two, one.

165
00:11:01,360 --> 00:11:10,360
In Valkyrie Boom, we've seen that a sealed room should contain and enhance an explosion better than a room with windows.

166
00:11:10,360 --> 00:11:13,360
Now they're ready to do it for real in small scale.

167
00:11:13,360 --> 00:11:16,360
Now in order to test this in small scale, I need two rooms.

168
00:11:16,360 --> 00:11:22,360
One that is scaled exactly correctly in all the details to Hitler's underground bunker.

169
00:11:22,360 --> 00:11:27,360
And another one that's scaled exactly to the above ground room where the explosion actually happened.

170
00:11:27,360 --> 00:11:32,360
I'm going to make them out of half inch steel plate.

171
00:11:32,360 --> 00:11:35,360
They're going to be nice and heavy, and in this way I won't be blowing them up.

172
00:11:35,360 --> 00:11:39,360
I'll just be seeing the difference of the propagation of the shock wave between the two.

173
00:11:39,360 --> 00:11:47,360
In search of a definitive yes or no to the myth, the focus is all on the lethal potential of those explosive shock waves.

174
00:11:47,360 --> 00:11:54,360
At Adam's in no doubt that both his scale rooms are sturdy enough to survive the ordeal.

175
00:11:54,360 --> 00:11:59,360
I'm going to tell you this is the heaviest scale model I've ever built.

176
00:12:02,360 --> 00:12:04,360
Come on in right here.

177
00:12:04,360 --> 00:12:09,360
Now there's no question that blowing stuff up is best done outdoors.

178
00:12:09,360 --> 00:12:18,360
And you know it's a big day on the bomb range when explosives experts Frank Doyle and J.D. Nelson are both there to help out.

179
00:12:21,360 --> 00:12:26,360
When we set off an explosive other than shrapnel, the thing we're worried about is known as a pressure wave.

180
00:12:26,360 --> 00:12:30,360
This is a moving wall of pressure that's radiating outward from the explosion.

181
00:12:30,360 --> 00:12:37,360
What kills is an increase in that kind of pressure that somebody experiences when they're near a blast.

182
00:12:37,360 --> 00:12:44,360
Now the question we're trying to answer is that if we set off an explosive in an enclosed room like a bunker,

183
00:12:44,360 --> 00:12:51,360
will we contain that blast and see an increased amount of pressure and therefore an increased lethality?

184
00:12:51,360 --> 00:12:57,360
More so than what we would see in an open room like a conference room where the pressure can escape through windows and doors.

185
00:12:57,360 --> 00:13:02,360
The business end of our testing today will be performed by this, a pressure transducer.

186
00:13:02,360 --> 00:13:09,360
This will be placed at a precise distance from the center of the blast and it converts the mechanical energy of the blast shock wave

187
00:13:09,360 --> 00:13:15,360
into an electrical impulse which will allow us to carefully measure and compare the two blasts we're doing today.

188
00:13:15,360 --> 00:13:19,360
Providing the boom for both rooms is a blasting cap.

189
00:13:19,360 --> 00:13:26,360
For a test on this scale, J.D. and Frank have chosen two robust yet cheeky number 10s.

190
00:13:26,360 --> 00:13:28,360
It's right there for one inch off the ground.

191
00:13:28,360 --> 00:13:31,360
Okay, if that's one inch, let's mark it and tape it.

192
00:13:31,360 --> 00:13:37,360
J.D. and Frank are ensuring the setup's exactly the same when the time comes to prime the bunker.

193
00:13:37,360 --> 00:13:39,360
Jamie, the cap's in place.

194
00:13:39,360 --> 00:13:40,360
Excellent.

195
00:13:40,360 --> 00:13:45,360
Hopefully safe behind the screen, Jamie counts down to the open room blast.

196
00:13:45,360 --> 00:13:49,360
And three, two, one.

197
00:13:49,360 --> 00:13:51,360
Nice.

198
00:13:51,360 --> 00:13:52,360
Let's go look at the data.

199
00:13:52,360 --> 00:13:53,360
Okay.

200
00:13:53,360 --> 00:13:57,360
Now remember, the rooms are to scale, but the charge isn't.

201
00:13:57,360 --> 00:14:02,360
We're not looking for damage, but the measure of pressure induced by the blast.

202
00:14:02,360 --> 00:14:04,360
So what's the data say?

203
00:14:04,360 --> 00:14:07,360
In the conference room, we've got a peak pressure of 14 psi.

204
00:14:07,360 --> 00:14:09,360
Excellent. Let's do the other one.

205
00:14:09,360 --> 00:14:10,360
Okay.

206
00:14:10,360 --> 00:14:15,360
So it's off to the bunker and just like the first room, this lodge needs a lid.

207
00:14:15,360 --> 00:14:18,360
It sounds like we're seeing a crypt.

208
00:14:18,360 --> 00:14:19,360
Correct.

209
00:14:19,360 --> 00:14:21,360
Well, that's kind of the whole idea.

210
00:14:21,360 --> 00:14:25,360
And with the roof welded tight, Jamie screws in the pressure transducer.

211
00:14:25,360 --> 00:14:28,360
This time around, it's a contained explosion.

212
00:14:28,360 --> 00:14:32,360
And if the theory is correct, we should see a higher psi in here.

213
00:14:32,360 --> 00:14:34,360
There we go.

214
00:14:34,360 --> 00:14:39,360
Now, J.D. and Frank ever so carefully insert the explosive.

215
00:14:39,360 --> 00:14:42,360
When they're done, we're almost ready to blow.

216
00:14:42,360 --> 00:14:47,360
And three, two, one.

217
00:14:47,360 --> 00:14:49,360
Bunk.

218
00:14:49,360 --> 00:14:57,360
Just like last time, the steel shell muffled the blast, but the drama is all in the data.

219
00:14:57,360 --> 00:14:59,360
What happened in the bunker?

220
00:14:59,360 --> 00:15:05,360
In the bunker, we got a peak pressure of 55 psi, almost four times the pressure we got in the conference room.

221
00:15:05,360 --> 00:15:07,360
Wow. That's a result.

222
00:15:07,360 --> 00:15:08,360
It is.

223
00:15:08,360 --> 00:15:14,360
As predicted, this potentially lethal pressure wave would do a lot more damage in the bunker,

224
00:15:14,360 --> 00:15:16,360
which is really good news for the myth.

225
00:15:16,360 --> 00:15:20,360
I think there really might be something to this one. Where do you want to go from here?

226
00:15:20,360 --> 00:15:23,360
Let's stop screwing around and ramp things up.

227
00:15:23,360 --> 00:15:28,360
Up next, Grant suffers for science, but not in silence.

228
00:15:28,360 --> 00:15:31,360
On to the tests.

229
00:15:34,360 --> 00:15:41,360
With the robot prime traction, the next step in the slap some sense myth is to run a series of tests.

230
00:15:41,360 --> 00:15:48,360
First with the subject as normal, then impaired in some way, then impaired again and slapped.

231
00:15:48,360 --> 00:15:55,360
The man in the hot seat is Grant simply because this face under pressure was far and away the funniest.

232
00:15:55,360 --> 00:15:58,360
And here's what he's going to face.

233
00:15:58,360 --> 00:16:02,360
For a slap sense myth experiment, we have four tasks to challenge Grant.

234
00:16:02,360 --> 00:16:08,360
We're going to test his reflexes, calculation, coordination, and visual and communication skills.

235
00:16:08,360 --> 00:16:14,360
And to make sure that slap effect doesn't wear off, each of these tasks will only be about a minute long.

236
00:16:14,360 --> 00:16:16,360
We'll get to the slap shortly.

237
00:16:16,360 --> 00:16:24,360
First up, Grant attempts all four tasks to give us an unimpaired baseline before we fetter his faculties.

238
00:16:24,360 --> 00:16:27,360
So this is how the reflex challenge is going to work.

239
00:16:27,360 --> 00:16:29,360
Grant will stand here on this grate.

240
00:16:29,360 --> 00:16:30,360
All right, you got it.

241
00:16:30,360 --> 00:16:34,360
Now above him are stars that are held up by electromagnets.

242
00:16:34,360 --> 00:16:36,360
These stars will drop one at a time.

243
00:16:36,360 --> 00:16:41,360
And his challenge is to catch stars before they hit the ground.

244
00:16:41,360 --> 00:16:44,360
Five, six, he's amazing.

245
00:16:44,360 --> 00:16:45,360
Seven, eight.

246
00:16:45,360 --> 00:16:46,360
What do you think?

247
00:16:46,360 --> 00:16:47,360
Well done.

248
00:16:47,360 --> 00:16:48,360
Eight out of eight.

249
00:16:48,360 --> 00:16:50,360
On to the next challenge.

250
00:16:50,360 --> 00:16:54,360
So for the coordination challenge, it'll be a good old fashioned shooting gallery.

251
00:16:54,360 --> 00:16:58,360
One with these air powered rifles firing corks.

252
00:16:58,360 --> 00:17:01,360
Two of 60 seconds to load the rifle.

253
00:17:01,360 --> 00:17:02,360
Three.

254
00:17:02,360 --> 00:17:05,360
And shoot all six targets.

255
00:17:05,360 --> 00:17:06,360
Four.

256
00:17:06,360 --> 00:17:07,360
All right.

257
00:17:07,360 --> 00:17:12,360
You shot five out of six.

258
00:17:12,360 --> 00:17:13,360
Well done.

259
00:17:13,360 --> 00:17:14,360
Thank you.

260
00:17:14,360 --> 00:17:17,360
Tests three and four are a bit more cerebral.

261
00:17:17,360 --> 00:17:24,360
First, a communication challenge as he and a blindfolded Tory try to replicate a pattern.

262
00:17:24,360 --> 00:17:25,360
Two tips on the triangle stitch.

263
00:17:25,360 --> 00:17:26,360
Okay.

264
00:17:26,360 --> 00:17:27,360
We're done.

265
00:17:27,360 --> 00:17:30,360
And then a quick fire math test.

266
00:17:30,360 --> 00:17:31,360
30 plus two.

267
00:17:31,360 --> 00:17:39,360
For this exercise, there is a time limit, which poses no problem as he nails three from three.

268
00:17:39,360 --> 00:17:44,360
With his brain firing at all cylinders, Grant scored predictably well.

269
00:17:44,360 --> 00:17:47,360
Now it's time to dial down his faculties.

270
00:17:47,360 --> 00:17:53,360
And according to Dr. Sanders, one of the best and simplest ways is to put him on ice.

271
00:17:53,360 --> 00:17:56,360
Oh, what is this?

272
00:17:56,360 --> 00:17:58,360
So we're going to chill you.

273
00:17:58,360 --> 00:17:59,360
Right.

274
00:17:59,360 --> 00:18:02,360
We'll leave you in here for a half hour until the cold takes effect on your body.

275
00:18:02,360 --> 00:18:05,360
And we'll pull you out and have you run the tests.

276
00:18:05,360 --> 00:18:06,360
And that'll be our control.

277
00:18:06,360 --> 00:18:07,360
That's right.

278
00:18:07,360 --> 00:18:09,360
After taking his temperature.

279
00:18:09,360 --> 00:18:10,360
Okay.

280
00:18:10,360 --> 00:18:13,360
We have a starting temperature of 97.1.

281
00:18:13,360 --> 00:18:14,360
Chill out.

282
00:18:14,360 --> 00:18:15,360
All right.

283
00:18:15,360 --> 00:18:16,360
Chill out.

284
00:18:16,360 --> 00:18:17,360
Oh, very funny.

285
00:18:17,360 --> 00:18:20,360
They leave Grant to shiver and speculate.

286
00:18:20,360 --> 00:18:23,360
Now I've been in really cold temperatures.

287
00:18:23,360 --> 00:18:27,360
The first thing that starts to go is your motor skills.

288
00:18:27,360 --> 00:18:30,360
The second thing that goes is your judgment.

289
00:18:30,360 --> 00:18:34,360
When the half hours up, Grant's lost seven degrees of body temperature.

290
00:18:34,360 --> 00:18:37,360
Technically, that's verging on hypothermia.

291
00:18:37,360 --> 00:18:39,360
So let's see if the doctor was right.

292
00:18:39,360 --> 00:18:42,360
If the cold has impaired him as much as a panic attack.

293
00:18:42,360 --> 00:18:43,360
Okay.

294
00:18:43,360 --> 00:18:44,360
Coordination.

295
00:18:44,360 --> 00:18:45,360
Are you ready for this challenge?

296
00:18:45,360 --> 00:18:46,360
I'm ready.

297
00:18:46,360 --> 00:18:47,360
Stay frosty.

298
00:18:47,360 --> 00:18:48,360
All right.

299
00:18:48,360 --> 00:18:49,360
He starts with the targets.

300
00:18:49,360 --> 00:18:54,360
Last time, he was five from six.

301
00:18:54,360 --> 00:18:56,360
This time, it's three.

302
00:18:56,360 --> 00:18:59,360
Now, it's time to move on to the next challenge.

303
00:18:59,360 --> 00:19:01,360
Next up is the math test.

304
00:19:01,360 --> 00:19:04,360
And those numbers aren't tripping off the tong like last time.

305
00:19:04,360 --> 00:19:08,360
Five plus eight is 33.

306
00:19:08,360 --> 00:19:10,360
It's like he's been drinking.

307
00:19:10,360 --> 00:19:11,360
210.

308
00:19:11,360 --> 00:19:12,360
Wrong.

309
00:19:12,360 --> 00:19:16,360
With time running out, he scored nothing.

310
00:19:16,360 --> 00:19:17,360
Time's up.

311
00:19:17,360 --> 00:19:19,360
Move on to the next challenge.

312
00:19:19,360 --> 00:19:21,360
Cache coordination now?

313
00:19:21,360 --> 00:19:23,360
Yeah, it almost seems cruel.

314
00:19:23,360 --> 00:19:25,360
That's science for you.

315
00:19:25,360 --> 00:19:26,360
One.

316
00:19:26,360 --> 00:19:27,360
Two.

317
00:19:27,360 --> 00:19:32,360
Two out of eight.

318
00:19:32,360 --> 00:19:34,360
Last time, he got eight out of eight.

319
00:19:34,360 --> 00:19:38,360
So hopes are not high for the last test.

320
00:19:38,360 --> 00:19:39,360
Okay.

321
00:19:39,360 --> 00:19:42,360
The seconds tick by.

322
00:19:42,360 --> 00:19:43,360
To the right.

323
00:19:43,360 --> 00:19:44,360
Oh, okay.

324
00:19:44,360 --> 00:19:45,360
Sorry.

325
00:19:45,360 --> 00:19:47,360
Flip it clockwise.

326
00:19:47,360 --> 00:19:48,360
Clockwise.

327
00:19:48,360 --> 00:19:51,360
And there's more than one pattern emerging.

328
00:19:51,360 --> 00:19:53,360
Retake clockwise and got it.

329
00:19:53,360 --> 00:19:54,360
Time.

330
00:19:54,360 --> 00:19:55,360
All right.

331
00:19:55,360 --> 00:19:59,360
Well, the results of the control test are you're definitely compromised.

332
00:19:59,360 --> 00:20:04,360
In fact, impaired Grant was trounced by non-impaired Grant.

333
00:20:04,360 --> 00:20:06,360
Now for the fun stuff.

334
00:20:06,360 --> 00:20:09,360
Time to stick you back in the freezer for a half hour,

335
00:20:09,360 --> 00:20:12,360
bring you out, slap you and do the test again.

336
00:20:12,360 --> 00:20:15,360
Grant's warmed up during testing.

337
00:20:15,360 --> 00:20:19,360
So it's back to the freezer to inhibit his brain again.

338
00:20:19,360 --> 00:20:23,360
And 30 mind and body numbing minutes later.

339
00:20:23,360 --> 00:20:25,360
You ready for the test?

340
00:20:27,360 --> 00:20:30,360
All right, Grant, have a seat in the slapping machine.

341
00:20:30,360 --> 00:20:31,360
Okay.

342
00:20:31,360 --> 00:20:32,360
Okay.

343
00:20:32,360 --> 00:20:33,360
You are cold.

344
00:20:33,360 --> 00:20:34,360
All right.

345
00:20:34,360 --> 00:20:36,360
You ready to get some sits slapped into you?

346
00:20:36,360 --> 00:20:38,360
Here we go.

347
00:20:42,360 --> 00:20:43,360
All right.

348
00:20:43,360 --> 00:20:44,360
Onto the reflexes test.

349
00:20:44,360 --> 00:20:49,360
There's no time to lose as they don't want the cold or the slap to wear off.

350
00:20:51,360 --> 00:20:58,360
One, two, three, four, five.

351
00:20:58,360 --> 00:20:59,360
Pretty good.

352
00:20:59,360 --> 00:21:00,360
Onto the next test.

353
00:21:00,360 --> 00:21:03,360
But first it's back in the truck for a top up.

354
00:21:03,360 --> 00:21:06,360
It's a method they'll repeat between each test.

355
00:21:06,360 --> 00:21:09,360
First the reach ill, then the slap.

356
00:21:11,360 --> 00:21:12,360
All right.

357
00:21:12,360 --> 00:21:14,360
All right, quick to the next challenge.

358
00:21:14,360 --> 00:21:15,360
Onto math.

359
00:21:15,360 --> 00:21:19,360
On the math quiz, well, it's hard to be sure,

360
00:21:19,360 --> 00:21:22,360
but he does seem more focused than last time.

361
00:21:22,360 --> 00:21:25,360
Minus 10 is 70 divided by two is 35.

362
00:21:25,360 --> 00:21:27,360
And that's time.

363
00:21:27,360 --> 00:21:30,360
Not as good as the practice, but better than the control.

364
00:21:30,360 --> 00:21:31,360
You got one out of three.

365
00:21:31,360 --> 00:21:33,360
Off to the chill on the slapping.

366
00:21:33,360 --> 00:21:38,360
It's fun to watch, but let's spare a thought for the man with his face on the line.

367
00:21:38,360 --> 00:21:39,360
I'm starting to feel bad for him.

368
00:21:39,360 --> 00:21:40,360
Me too.

369
00:21:40,360 --> 00:21:41,360
Just a little.

370
00:21:43,360 --> 00:21:46,360
On to the test.

371
00:21:46,360 --> 00:21:47,360
Let's go.

372
00:21:47,360 --> 00:21:52,360
Right about now, Carrie and Tori are thankful that the gun only shoots corks.

373
00:21:52,360 --> 00:22:00,360
Our expert said that the physiological response to getting slapped is the fight or flight adrenaline rush that you get.

374
00:22:00,360 --> 00:22:07,360
I'm pretty sure that's what I had because when I got slapped, I was ready to like jump up and hit something.

375
00:22:07,360 --> 00:22:15,360
So with one last long shiver and a hopefully restorative slap, Grant once again consorts with the enemy.

376
00:22:15,360 --> 00:22:18,360
You're sounding a lot more focused. It's good. I like where you're going.

377
00:22:18,360 --> 00:22:20,360
Rotate back counterclockwise.

378
00:22:20,360 --> 00:22:26,360
But is he on track to beat the last time trial? Only Carrie knows for sure.

379
00:22:26,360 --> 00:22:31,360
Okay, there we have it. Not as good as the practice, but better than the control.

380
00:22:32,360 --> 00:22:39,360
The results are as clear as ice. When Grant was part crippled by cold, his performance fell off across the board.

381
00:22:39,360 --> 00:22:45,360
After the slap, he bouts back, but not far enough to match his unimpaired baseline.

382
00:22:45,360 --> 00:22:52,360
I have to say that I'm starting to believe that there's something to being able to slap sense into someone.

383
00:22:52,360 --> 00:22:56,360
The myth looks plausible, but have we gone far enough to prove the point?

384
00:22:56,360 --> 00:23:02,360
They have still room to ramp this one up, and the bonus for Grant is he'll get his revenge.

385
00:23:02,360 --> 00:23:09,360
Coming up, Adam and Jamie find that building a bunker might be more dangerous than blowing it up.

386
00:23:14,360 --> 00:23:18,360
Well, so far so good. Our small scale task seems to be supporting the theory.

387
00:23:18,360 --> 00:23:21,360
I think it's time to go full scale. Ramp things up.

388
00:23:21,360 --> 00:23:23,360
I totally agree. I've got an idea about that.

389
00:23:23,360 --> 00:23:31,360
Since the conventional wisdom is basically that all things being equal, the enclosed explosion is deadlier, let's make all things equal.

390
00:23:31,360 --> 00:23:36,360
Let's get two identically sized shipping containers and dress them both precisely the same.

391
00:23:36,360 --> 00:23:44,360
Same amount of explosives, same briefcase, same conference table that Hitler was standing at in each container, except in one, we cut windows in it,

392
00:23:44,360 --> 00:23:50,360
and in the other, we bury it underground. Then, we detonate the same amount of explosives in each and see what we get.

393
00:23:50,360 --> 00:23:51,360
I love it.

394
00:23:51,360 --> 00:23:52,360
Great.

395
00:23:52,360 --> 00:23:59,360
So it's back to the bomb range to put this myth of the two rooms at Wolf's Lair to the ultimate test.

396
00:23:59,360 --> 00:24:05,360
For this test, the role of our underground bunker and our above-ground conference room will be played by a pair of truck containers.

397
00:24:05,360 --> 00:24:11,360
These truck containers, now, if you'll excuse me, I'm going to take one, put it into position, and cut some windows out of it.

398
00:24:11,360 --> 00:24:17,360
It's a point of pride here on the show that when the going gets tough, we don't send out for the contractors.

399
00:24:17,360 --> 00:24:26,360
It's agreed that the best way to make a shipping container more like an underground bunker is to slip it tight inside a 12-foot deep dirt trench.

400
00:24:26,360 --> 00:24:28,360
And Jamie's the man for the job.

401
00:24:28,360 --> 00:24:33,360
Now that we've covered care and feeding of the Heinemann, it's important to talk about stimulation.

402
00:24:33,360 --> 00:24:38,360
Heinemann is never happier than when the Heinemann is simply digging a big hole.

403
00:24:38,360 --> 00:24:43,360
So give your Heinemann the opportunity to dig a large hole preferably with farm equipment.

404
00:24:43,360 --> 00:24:45,360
Oh, yeah.

405
00:24:45,360 --> 00:24:48,360
That's what I call a Heinemann in its element.

406
00:24:48,360 --> 00:24:57,360
Now let's see a savage in his, hauling the soon-to-be situation room to its last resting place as a delicate operation.

407
00:24:57,360 --> 00:25:03,360
That container weighs two and a half tons, but Adam drops it pretty much on a dime.

408
00:25:03,360 --> 00:25:05,360
That doesn't look bad.

409
00:25:05,360 --> 00:25:10,360
I mean, it's not gorgeous, but not bad. It's pretty good.

410
00:25:10,360 --> 00:25:13,360
Well, there's still time enough to spruce up the old place.

411
00:25:13,360 --> 00:25:19,360
Item number one on the job sheet is to mark up and carve out some windows.

412
00:25:19,360 --> 00:25:22,360
Oh, that's nice.

413
00:25:22,360 --> 00:25:24,360
There's a whole place out there.

414
00:25:24,360 --> 00:25:28,360
Okay, so we can all give thanks that this man never became a dentist.

415
00:25:28,360 --> 00:25:31,360
But you have to admit, he gets the job done.

416
00:25:31,360 --> 00:25:33,360
Ah!

417
00:25:35,360 --> 00:25:38,360
You can never tell whether those things open in or out.

418
00:25:38,360 --> 00:25:43,360
Back in the trenches, Jamie measures the depth and the breadth of his bunker burial plot.

419
00:25:43,360 --> 00:25:45,360
Perfect.

420
00:25:45,360 --> 00:25:49,360
Next on the schedule is blazing the windows.

421
00:25:49,360 --> 00:25:57,360
I know what you're saying. You're saying, Adam, I'm pretty sure the Germans had more sophisticated window technology than duct tape.

422
00:25:57,360 --> 00:26:01,360
And I agree. That's not what this test is about, though.

423
00:26:01,360 --> 00:26:08,360
This is a purely relative test, testing an explosion in an enclosed space versus an open space.

424
00:26:08,360 --> 00:26:12,360
This is literally window dressing.

425
00:26:12,360 --> 00:26:17,360
Over at Heinemann's Hall, Jamie's been weaving his own kind of magic.

426
00:26:17,360 --> 00:26:20,360
The building's been slotted as neat as you please into the trench.

427
00:26:20,360 --> 00:26:22,360
What's good now?

428
00:26:22,360 --> 00:26:27,360
It's packed in and covered with earth to simulate Hitler's bunker in the woods.

429
00:26:27,360 --> 00:26:34,360
With preparations going so well, you can help feeling that something, somewhere, is going to crack.

430
00:26:34,360 --> 00:26:39,360
Surprisingly, it's not Adam's windows, but Jamie's container.

431
00:26:39,360 --> 00:26:41,360
Oh!

432
00:26:41,360 --> 00:26:45,360
It's just what you don't want to hear at the end of a long day's labor.

433
00:26:45,360 --> 00:26:47,360
I just heard it. Crunch.

434
00:26:47,360 --> 00:26:49,360
Oh, no. Have we opened it up yet?

435
00:26:49,360 --> 00:26:50,360
No.

436
00:26:50,360 --> 00:26:54,360
Oh, criminy. That would suck.

437
00:26:54,360 --> 00:26:57,360
And that would be an understatement.

438
00:26:57,360 --> 00:27:00,360
Oh. Did you hear that?

439
00:27:00,360 --> 00:27:01,360
Yeah.

440
00:27:01,360 --> 00:27:02,360
I don't want to go in there.

441
00:27:02,360 --> 00:27:03,360
No.

442
00:27:03,360 --> 00:27:11,360
It seems the problem stems back to supply, as they discover this container is part fiberglass and not nearly as strong as the other one.

443
00:27:11,360 --> 00:27:13,360
Dude, I know.

444
00:27:13,360 --> 00:27:15,360
What do we do?

445
00:27:15,360 --> 00:27:17,360
Get another one.

446
00:27:17,360 --> 00:27:26,360
Set back all right, and with the full-scale testing set for tomorrow morning, someone needs to do something and do it fast.

447
00:27:26,360 --> 00:27:28,360
My suit.

448
00:27:28,360 --> 00:27:33,360
Straight ahead, hungry, tired, cold and slapped.

449
00:27:33,360 --> 00:27:38,360
Harry and Tori face the ultimate challenge.

450
00:27:38,360 --> 00:27:41,360
She had a bad day.

451
00:27:42,360 --> 00:27:46,360
Okay, so Grant's tests showed that slapping made a difference.

452
00:27:46,360 --> 00:27:48,360
Yeah, but you know what? I don't think we were thorough enough.

453
00:27:48,360 --> 00:27:54,360
I mean, yeah, we put them in the cold and that inhibited his brain, but I think we could add a couple more things.

454
00:27:54,360 --> 00:27:57,360
Maybe sleep deprivation or even hunger.

455
00:27:57,360 --> 00:27:58,360
No!

456
00:27:58,360 --> 00:27:59,360
Yeah.

457
00:27:59,360 --> 00:28:01,360
And I think there wasn't enough consequence to his errors.

458
00:28:01,360 --> 00:28:06,360
I think we need to do something like a gun range test, like a police training test where you have to make quick, split-second decisions.

459
00:28:06,360 --> 00:28:08,360
Okay, perfect. But I have one change.

460
00:28:08,360 --> 00:28:11,360
This time, I administer the test and you two get slapped.

461
00:28:11,360 --> 00:28:13,360
No, that's a terrible idea.

462
00:28:13,360 --> 00:28:16,360
Yeah, I think we should take a vote on that one. All in favor of Grant.

463
00:28:16,360 --> 00:28:18,360
All in favor of Tori and Carrie.

464
00:28:19,360 --> 00:28:23,360
Producer voted. She gets the override. You two are getting slapped.

465
00:28:23,360 --> 00:28:30,360
So they'll both go all day without food or sleep and of course spend some time in the deep freeze.

466
00:28:30,360 --> 00:28:37,360
This should inhibit their brain function as much as hysterical panic without actually inducing it.

467
00:28:37,360 --> 00:28:45,360
And taking the test to a shooting range means they'll be forced to make quick fire decisions with potentially serious consequences.

468
00:28:46,360 --> 00:28:54,360
Okay, so this is our two-minute shooting drill course that we're going to be putting our frozen, tired and starving Tori and Carrie through.

469
00:28:54,360 --> 00:28:58,360
When we say go, random targets will flip over, good and bad.

470
00:28:58,360 --> 00:29:02,360
They will have to choose only the bad guy and not shoot the good guy.

471
00:29:02,360 --> 00:29:09,360
They'll each have 30 rounds and on Grant's command, they'll advance twice down the room to complete the test.

472
00:29:09,360 --> 00:29:17,360
These guns are in fact real guns, but they've been specially modified with a different barrel that allows them to fire these rounds,

473
00:29:17,360 --> 00:29:20,360
which are training rounds and markers. They're called SIMS.

474
00:29:20,360 --> 00:29:24,360
They're filled with paint so that you can identify where they hit.

475
00:29:24,360 --> 00:29:27,360
Carrie and Tori are called on to help reassemble the robot.

476
00:29:27,360 --> 00:29:33,360
And after a day of deprivation, they're exhausted and starving, and Grant's not making it easy.

477
00:29:33,360 --> 00:29:36,360
So how many times did I get slapped yesterday?

478
00:29:36,360 --> 00:29:41,360
That looks good. Oh my gosh. Is that a triple?

479
00:29:41,360 --> 00:29:46,360
Then it's into the ice truck for 30 minutes to consolidate their incapacity.

480
00:29:50,360 --> 00:29:56,360
To be scrupulous, Carrie and Tori first ran the course yesterday when they were still hail and hearty.

481
00:29:56,360 --> 00:30:03,360
They both fired 30 rounds and missed just once. So that's our uninhibited baseline.

482
00:30:03,360 --> 00:30:08,360
Now it's time to find out just how impaired they've become, starting with Carrie.

483
00:30:08,360 --> 00:30:12,360
Eyes on. Pick up your firearm.

484
00:30:12,360 --> 00:30:18,360
I am really tired from tensing. I am freezing cold. I am starving.

485
00:30:18,360 --> 00:30:21,360
Ready. And begin.

486
00:30:21,360 --> 00:30:23,360
I think I'm getting a headache.

487
00:30:23,360 --> 00:30:29,360
So she's less than her usual bubbly self, but will it impair her performance?

488
00:30:29,360 --> 00:30:35,360
Going through the course was a lot harder than I thought it was going to be because I was shaking so much that I couldn't hold my gun straight.

489
00:30:35,360 --> 00:30:46,360
And it's like I can't concentrate. It was just, my head is tired. I can't focus.

490
00:30:47,360 --> 00:30:55,360
At the end of the test, Carrie at least hasn't shot any good guys, but the round she got off were really a case of hit and miss.

491
00:30:55,360 --> 00:30:58,360
You fired a total of 19 rounds and eight of them were hits.

492
00:30:58,360 --> 00:30:59,360
It's like an F.

493
00:30:59,360 --> 00:31:04,360
Yeah, but bear in mind, I mean you're tired, hungry and cold. You're supposed to be impaired.

494
00:31:04,360 --> 00:31:06,360
Mission accomplished.

495
00:31:06,360 --> 00:31:08,360
All right, let's go get Tori.

496
00:31:09,360 --> 00:31:14,360
Hungry, tired and chilled, not in a good way. Tori takes up the challenge.

497
00:31:14,360 --> 00:31:20,360
Being inside that freezer truck was miserable. My fingers are getting numb. I'm starting to shiver.

498
00:31:20,360 --> 00:31:30,360
I could feel my muscles tightening up, you know, just to stay warm. And I'm thinking to myself, if I can't even feel my finger, how am I going to feel the gun in order to pull the trigger?

499
00:31:31,360 --> 00:31:32,360
Reloaded.

500
00:31:33,360 --> 00:31:39,360
Well, he does get to grips with the gun, but just how many of those paint filled bullets have hit the targets?

501
00:31:40,360 --> 00:31:42,360
He had a bad day.

502
00:31:42,360 --> 00:31:44,360
Okay, John, so how did Tori do?

503
00:31:44,360 --> 00:31:49,360
He did really well. Not only did we get all of the shots on target, but he grouped him together very well.

504
00:31:49,360 --> 00:31:51,360
Now, on the overall course, how did I do?

505
00:31:51,360 --> 00:31:57,360
Well, we counted him up. He didn't hit any of the good guys. He got off 24 rounds and we had 21 hits.

506
00:31:57,360 --> 00:32:05,360
There's not much in it, but just like Carrie, he did worse when affected by hunger and cold and no sleep for a day.

507
00:32:06,360 --> 00:32:11,360
Now we're ready to find out once and for all if a slap makes a difference.

508
00:32:15,360 --> 00:32:26,360
Yesterday did not end well for Adam and Jamie, but with a new up-to-code container secured and currently being reinstalled, it's all back on track.

509
00:32:26,360 --> 00:32:32,360
That gives Adam a chance to explain his amazing design for the real stars of the show.

510
00:32:32,360 --> 00:32:35,360
A pair of high-tech faux furors.

511
00:32:35,360 --> 00:32:38,360
In any explosion, there's pretty much two things that are going to kill you.

512
00:32:38,360 --> 00:32:46,360
One is the pressure wave and two is the shrapnel, and we'll be measuring both using this big block of urethane foam.

513
00:32:46,360 --> 00:32:53,360
This will, in fact, be our Hitler standing at the conference table, and it will have a pressure transducer placed in the center of the chest, front and back,

514
00:32:53,360 --> 00:32:57,360
to measure the blast pressures coming off the explosion.

515
00:32:57,360 --> 00:33:03,360
And because it's a big block of foam, it is ideal for measuring the shrapnel injuries that might have been sustained,

516
00:33:03,360 --> 00:33:09,360
because anything, any piece of wood, any splinter that flies off this explosion is going to stick right in this foam

517
00:33:09,360 --> 00:33:13,360
and give us a really good idea of the kind of injuries that Hitler might have sustained.

518
00:33:13,360 --> 00:33:21,360
For Adam's design to work properly, the sensors and the wires need protection, hence the two metal plates.

519
00:33:21,360 --> 00:33:26,360
If all goes to plan, the chest sensor will measure the initial blast wave of the bomb,

520
00:33:26,360 --> 00:33:31,360
and the back sensor will register shock waves that reverberate off the wall.

521
00:33:31,360 --> 00:33:35,360
Right. I think our shrapnel collectors are ready for testing.

522
00:33:35,360 --> 00:33:43,360
It's back to the bomb range to hopefully show if in some alternative universe, the bomb and the bunker would have killed Hitler.

523
00:33:43,360 --> 00:33:51,360
They'll begin by blowing up the situation room and see if the damage matches the actual event in 1944.

524
00:33:51,360 --> 00:33:55,360
In addition to our electronic data point about the blast pressure in this experiment,

525
00:33:55,360 --> 00:34:00,360
we are also going to grab an analog data point with this, one of our handy little burst discs.

526
00:34:00,360 --> 00:34:04,360
This is set at 100 psi, and if this bursts, it equals death.

527
00:34:04,360 --> 00:34:07,360
And it doesn't get much clearer than that.

528
00:34:07,360 --> 00:34:14,360
With all the equipment in place and checked, J.D. and Frank measure out an historically precise chunk of C4.

529
00:34:14,360 --> 00:34:19,360
975 grams. Let's pack it up. Perfect.

530
00:34:19,360 --> 00:34:20,360
It's good to go.

531
00:34:20,360 --> 00:34:28,360
Inside the room, the last act of sedition is to connect the explosive to a firing mechanism in the safety bunker.

532
00:34:28,360 --> 00:34:31,360
There's a lot riding on the result.

533
00:34:31,360 --> 00:34:39,360
To validate the upcoming bunker test, they need this blast to be almost identical to the real one that failed to kill Hitler.

534
00:34:39,360 --> 00:34:45,360
Situation room control explosion. In three, two, one.

535
00:34:50,360 --> 00:34:52,360
Boom.

536
00:34:54,360 --> 00:34:56,360
I wouldn't want to be in that room.

537
00:34:57,360 --> 00:35:02,360
It's hard to imagine anyone surviving this, but that's what they're hoping.

538
00:35:02,360 --> 00:35:04,360
Look, we got a new doorway.

539
00:35:04,360 --> 00:35:06,360
Watch out for some nails.

540
00:35:06,360 --> 00:35:10,360
It did what it said it would do to the floor. There's a hole there.

541
00:35:10,360 --> 00:35:16,360
Wow, look at that. Mr. Hitler's in three rather large chunks.

542
00:35:16,360 --> 00:35:19,360
Now when I see intact burst discs.

543
00:35:19,360 --> 00:35:22,360
Absolutely. Look at that. It's totally intact.

544
00:35:22,360 --> 00:35:29,360
So they know the blast was less than 100 psi, and Hitler's actually a lot healthier than he looks.

545
00:35:29,360 --> 00:35:36,360
Wow, I mean it really is clear that while he might have taken a lot of damage from splinters in his lower half, his head completely untouched.

546
00:35:36,360 --> 00:35:43,360
Yeah, that's what the Gestapo report said, that he had splinters in his legs, but from the waist up, he's pretty well intact.

547
00:35:43,360 --> 00:35:48,360
So that supports the burst disc, that it's a survivable blast we know from history that Hitler survived it.

548
00:35:48,360 --> 00:35:50,360
So kudos on a good control.

549
00:35:50,360 --> 00:35:51,360
Boom.

550
00:35:52,360 --> 00:35:55,360
In fact, it looks like a great control.

551
00:35:55,360 --> 00:35:59,360
But will David's figures confirm the non-kill?

552
00:35:59,360 --> 00:36:01,360
To David, what would we get?

553
00:36:01,360 --> 00:36:06,360
We had an average of 18 psi for just over a millisecond, which is definitely survivable.

554
00:36:06,360 --> 00:36:08,360
I'll be darned.

555
00:36:08,360 --> 00:36:20,360
All of our data shows that our Hitler could have totally survived this blast, despite the fact that when we watched it blow up, we all thought, oh, crap.

556
00:36:20,360 --> 00:36:22,360
This couldn't have gone better.

557
00:36:24,360 --> 00:36:29,360
Now the question is, what will happen in the underground bunker when we contain that blast wave?

558
00:36:29,360 --> 00:36:34,360
Still to come, what would have happened with the bomb in the bunker?

559
00:36:34,360 --> 00:36:37,360
One, oh!

560
00:36:40,360 --> 00:36:45,360
A slap in the face can be painful, surprising, and downright disturbing.

561
00:36:45,360 --> 00:36:48,360
But can it really be used to focus your brain?

562
00:36:48,360 --> 00:36:50,360
I know I'm a much better shot than that.

563
00:36:50,360 --> 00:36:52,360
We're about to find out.

564
00:36:52,360 --> 00:36:54,360
Sorry, Carrie.

565
00:36:57,360 --> 00:36:59,360
All right, good, good.

566
00:36:59,360 --> 00:37:00,360
How you feeling?

567
00:37:00,360 --> 00:37:02,360
I just got smacked.

568
00:37:02,360 --> 00:37:03,360
Okay.

569
00:37:03,360 --> 00:37:06,360
But will she improve or implode?

570
00:37:06,360 --> 00:37:08,360
Let's begin the testing.

571
00:37:08,360 --> 00:37:10,360
Ready and begin.

572
00:37:10,360 --> 00:37:12,360
And let Carrie handle the commentary.

573
00:37:12,360 --> 00:37:15,360
Getting slapped really refocused me.

574
00:37:15,360 --> 00:37:21,360
And I feel like that slap is a lot harder than when we calibrated it originally.

575
00:37:21,360 --> 00:37:29,360
I don't know if I'm just really cold, extremely irritated, starving, but felt really focused.

576
00:37:29,360 --> 00:37:30,360
She did really well.

577
00:37:30,360 --> 00:37:34,360
She got off a total of 22 rounds and 16 on target.

578
00:37:34,360 --> 00:37:35,360
So a very big improvement.

579
00:37:35,360 --> 00:37:36,360
Nice.

580
00:37:36,360 --> 00:37:37,360
And no good guys.

581
00:37:37,360 --> 00:37:38,360
Very good.

582
00:37:38,360 --> 00:37:42,360
Carrie scored well enough to well and truly prop up the myth.

583
00:37:42,360 --> 00:37:44,360
Now it's all down to Tori.

584
00:37:44,360 --> 00:37:45,360
Okay, man.

585
00:37:45,360 --> 00:37:47,360
How you feeling?

586
00:37:47,360 --> 00:37:52,360
Cold, disoriented, a little foggy in the head.

587
00:37:52,360 --> 00:37:53,360
Okay.

588
00:38:00,360 --> 00:38:02,360
All right, let's do this.

589
00:38:02,360 --> 00:38:04,360
All right, ready.

590
00:38:04,360 --> 00:38:05,360
Okay.

591
00:38:05,360 --> 00:38:06,360
And begin.

592
00:38:06,360 --> 00:38:10,360
And starts the test that will hopefully settle this once and for all.

593
00:38:10,360 --> 00:38:15,360
I am so surprised at how different I felt before the slap and then after the slap.

594
00:38:15,360 --> 00:38:17,360
We've been in the freezer for a half hour.

595
00:38:17,360 --> 00:38:21,360
I got slapped and instantly I feel awake and alive.

596
00:38:21,360 --> 00:38:24,360
And I felt like I moved through the course a lot better.

597
00:38:27,360 --> 00:38:28,360
Okay, John.

598
00:38:28,360 --> 00:38:29,360
So what are the results?

599
00:38:29,360 --> 00:38:30,360
Really good.

600
00:38:30,360 --> 00:38:34,360
Tori got off a total of 27 shots, 26 on target.

601
00:38:34,360 --> 00:38:36,360
That right there is a clear cut result.

602
00:38:36,360 --> 00:38:40,360
They never got back to their unimpaired baselines, but that's not the benchmark.

603
00:38:40,360 --> 00:38:45,360
The myth is that slapping revives an impaired mind and body.

604
00:38:45,360 --> 00:38:48,360
Well, if we put your results to my results and his results all together,

605
00:38:48,360 --> 00:38:50,360
I think we can call this myth confirmed.

606
00:38:50,360 --> 00:38:55,360
Yeah, we were all compromised and yet all of us had significant improvement after being slapped.

607
00:38:55,360 --> 00:39:00,360
Who would have thought a simple slap would help you to focus and improve your ability?

608
00:39:00,360 --> 00:39:01,360
Confirmed.

609
00:39:01,360 --> 00:39:02,360
Confirmed.

610
00:39:02,360 --> 00:39:03,360
Confirmed.

611
00:39:08,360 --> 00:39:13,360
As this happened to you, are Allied bombers wrecking your dreams of world domination

612
00:39:13,360 --> 00:39:16,360
with their pesky bombs interrupting your meetings?

613
00:39:16,360 --> 00:39:20,360
Have you considered that the problem might be that you're meeting above ground?

614
00:39:20,360 --> 00:39:23,360
Well, have we got a solution for you?

615
00:39:23,360 --> 00:39:27,360
After making their five easy payments, they've got the container they wanted.

616
00:39:27,360 --> 00:39:30,360
It's been partially buried to behave like a bunker,

617
00:39:30,360 --> 00:39:34,360
but they're careful to make sure the fittings, the props, and the explosives

618
00:39:34,360 --> 00:39:38,360
are precisely the same as they were in the last test.

619
00:39:38,360 --> 00:39:40,360
Thank you, sir.

620
00:39:40,360 --> 00:39:43,360
The only thing that is different is the room.

621
00:39:43,360 --> 00:39:47,360
It's the same size, but it's contained, so when we see a pressure wave,

622
00:39:47,360 --> 00:39:49,360
it doesn't have anywhere to go.

623
00:39:49,360 --> 00:39:51,360
Now, theater's in.

624
00:39:51,360 --> 00:39:53,360
You think we're going to kill Hitler this time?

625
00:39:53,360 --> 00:39:54,360
Yes.

626
00:39:54,360 --> 00:39:55,360
Ah, cool.

627
00:39:55,360 --> 00:39:56,360
Well, let's seal it up.

628
00:39:56,360 --> 00:39:59,360
The closest thing they have to a weak point is the front door.

629
00:39:59,360 --> 00:40:03,360
So, Jamie, perhaps recalling his days building the transcontinental railroad,

630
00:40:03,360 --> 00:40:07,360
decides to buttress the bunker with railroad ties.

631
00:40:07,360 --> 00:40:12,360
Now, to briefly retread the trail of destruction that brought us to this epic moment.

632
00:40:12,360 --> 00:40:16,360
Now, we know from our small-scale testing that a confined explosion will yield

633
00:40:16,360 --> 00:40:19,360
a higher blast pressure than an unconfined explosion.

634
00:40:19,360 --> 00:40:24,360
And in our full-scale baseline, we exactly replicated the actual attempt on Hitler's life

635
00:40:24,360 --> 00:40:26,360
and showed that it was completely survivable.

636
00:40:26,360 --> 00:40:30,360
But would anyone stand a ghost of a chance in an underground bunker

637
00:40:30,360 --> 00:40:33,360
with close to a kilo of high explosive?

638
00:40:33,360 --> 00:40:38,360
To confirm the myth, they need to kill Hitler beyond any shadow of a doubt.

639
00:40:38,360 --> 00:40:42,360
In three, two, one.

640
00:40:42,360 --> 00:40:44,360
Oh!

641
00:40:44,360 --> 00:40:46,360
Oh, oh, oh, oh!

642
00:40:46,360 --> 00:40:47,360
Uh-oh.

643
00:40:47,360 --> 00:40:49,360
I think the doors are open.

644
00:40:49,360 --> 00:40:53,360
We've exposed the creamy center.

645
00:40:54,360 --> 00:40:56,360
Well, the bunker still looks intact, though.

646
00:40:56,360 --> 00:40:59,360
It does. Let's approach it gingerly.

647
00:41:01,360 --> 00:41:05,360
The bomb blew the sleeper's 150 feet,

648
00:41:05,360 --> 00:41:09,360
so it's no surprise that inside, it's a train wreck.

649
00:41:09,360 --> 00:41:12,360
But there's one more shockwave to come.

650
00:41:12,360 --> 00:41:15,360
Dude, the first test.

651
00:41:15,360 --> 00:41:17,360
Totally intact.

652
00:41:17,360 --> 00:41:20,360
I would not have called it. Look at this place.

653
00:41:20,360 --> 00:41:23,360
It does look like the guys have blown their deposit.

654
00:41:23,360 --> 00:41:27,360
Look at the devastation here. There's nothing left in here but splinters.

655
00:41:27,360 --> 00:41:31,360
But the crucial stats on survivability rest with David.

656
00:41:31,360 --> 00:41:32,360
What'd we get?

657
00:41:32,360 --> 00:41:36,360
We got an average of 30 psi for just over one millisecond.

658
00:41:36,360 --> 00:41:38,360
That's it? That's it. It was survivable.

659
00:41:38,360 --> 00:41:40,360
I'll be darned.

660
00:41:40,360 --> 00:41:43,360
It's pretty close to an unbelievable result.

661
00:41:43,360 --> 00:41:47,360
While a pressure wave as low as 15 psi could be lethal,

662
00:41:47,360 --> 00:41:50,360
it would have to last for at least 30 milliseconds,

663
00:41:50,360 --> 00:41:53,360
and this blast didn't come close.

664
00:41:53,360 --> 00:41:57,360
People ask us all the time if we come up with results on the show that surprise us,

665
00:41:57,360 --> 00:42:00,360
and here is actually a fantastic example.

666
00:42:00,360 --> 00:42:04,360
We are gobsmacked. We went into this explosion pretty much feeling guaranteed

667
00:42:04,360 --> 00:42:07,360
that Hitler was going to die, and all of our data shows the opposite,

668
00:42:07,360 --> 00:42:10,360
that this was a survivable blast.

669
00:42:14,360 --> 00:42:16,360
That was surprising, huh?

670
00:42:16,360 --> 00:42:19,360
Totally surprising. I was convinced that Hitler was going to die.

671
00:42:19,360 --> 00:42:21,360
Let's go.

672
00:42:21,360 --> 00:42:23,360
If she would have used more explosives.

673
00:42:23,360 --> 00:42:26,360
That's your answer for everything.

674
00:42:28,360 --> 00:42:30,360
And I love these results.

675
00:42:30,360 --> 00:42:32,360
If you were standing where Hitler was in relation to the blast,

676
00:42:32,360 --> 00:42:37,360
you would have survived whether that blast occurred in the bunker or in the situation room.

677
00:42:37,360 --> 00:42:41,360
Yeah, the myth that Hitler only survived because of the change of venue is totally busted.

678
00:42:41,360 --> 00:42:44,360
Totally, totally and completely busted.

679
00:42:44,360 --> 00:42:47,360
If the bomb had been at his feet, as was the original plan,

680
00:42:47,360 --> 00:42:49,360
we might have a completely different story.

681
00:42:49,360 --> 00:42:52,360
The placement of the bomb, the quantity of the explosives,

682
00:42:52,360 --> 00:42:54,360
much more important than the room.

683
00:42:54,360 --> 00:42:57,360
Yeah, I just love the counterintuitive conclusions.

684
00:42:57,360 --> 00:42:59,360
I do too.
