I have an idea. 58 00:03:10,000 --> 00:03:11,000 Okay. 59 00:03:12,000 --> 00:03:15,000 This is Jamie's Wheel of Misfortune, 60 00:03:15,000 --> 00:03:22,000 a man-sized hamster tumbler that's purpose-built to not only disorient Adam, but to work underwater. 61 00:03:22,000 --> 00:03:23,000 This is it. 62 00:03:25,000 --> 00:03:31,000 Adam will come and stand here like so, and I'll rotate him around and around. 63 00:03:31,000 --> 00:03:39,000 And when I stop, he can just freely come out like this and he'll swim off in whatever direction he thinks is up. 64 00:03:40,000 --> 00:03:43,000 It's a straightforward plan that needs just one more thing. 65 00:03:43,000 --> 00:03:46,000 H2O and plenty of it. 66 00:03:46,000 --> 00:03:48,000 Okay. Off to the pool. 67 00:03:48,000 --> 00:03:54,000 They'll need at least eight feet of water, and this dive school's got ten in the deep end. 68 00:03:55,000 --> 00:03:57,000 Let me explain how this thing's going to break down. 69 00:03:57,000 --> 00:04:02,000 Jamie and I will walk the disorientation rig into the pool and set it on the bottom. 70 00:04:02,000 --> 00:04:08,000 Once it's in place, Jamie will position himself next to the rig in full scuba gear, and I will swim down to it. 71 00:04:09,000 --> 00:04:16,000 Put my feet on the paddles, put my hands in the handles, and put on a pair of blindfold goggles that completely negate my ability to see. 72 00:04:16,000 --> 00:04:19,000 When I'm ready, Jamie will begin spinning, spinning, spinning. 73 00:04:19,000 --> 00:04:28,000 I'll have no idea which direction I'll end up in, but when he stops, he'll tap the rig twice, and I will swim whichever direction I think is up. 74 00:04:28,000 --> 00:04:35,000 And if your car crashes at night, hence the blindfold, that could be a whole lot harder than it sounds. 75 00:04:38,000 --> 00:04:43,000 You know when you're hanging upside down on the monkey bars and the blood rushes to your head, you feel that pressure? 76 00:04:43,000 --> 00:04:48,000 I didn't expect this, but I can feel that pressure under water too. 77 00:04:48,000 --> 00:04:58,000 After 30 seconds of blindfolded spinning, Jamie sets Adam adrift, and without hesitation, he heads straight for the surface. 78 00:05:00,000 --> 00:05:03,000 In the name of due diligence, they try it again. 79 00:05:03,000 --> 00:05:05,000 And again. 80 00:05:08,000 --> 00:05:10,000 With exactly the same result. 81 00:05:10,000 --> 00:05:13,000 Ha! Found up again! 82 00:05:15,000 --> 00:05:17,000 You're three for three, huh? 83 00:05:17,000 --> 00:05:20,000 I am. I think it's your turn to try this rig out. 84 00:05:20,000 --> 00:05:21,000 I'm game. 85 00:05:21,000 --> 00:05:22,000 Alright, let's do it. 86 00:05:24,000 --> 00:05:32,000 Adam's efforts are a kick in the teeth for the myth, so let's see if Jamie's internal compass survives the big spin. 87 00:05:32,000 --> 00:05:34,000 He'll also do it three times over. 88 00:05:38,000 --> 00:05:42,000 We came here to find out if it was possible to lose your sense of direction underwater. 89 00:05:42,000 --> 00:05:51,000 And based on our testing, my feeling is that while there are a lot of cues to tell you which way is up, it's really quite easy to get distracted. 90 00:05:52,000 --> 00:06:02,000 That blast escape left Jamie geographically embarrassed, so the concept of losing your way upside down now looks like it might hold water. 91 00:06:02,000 --> 00:06:04,000 So what do you think? 92 00:06:04,000 --> 00:06:11,000 I think it's all about presence of mind, because on one of the tests, I was having problems with my sinuses and I got a little distracted. 93 00:06:11,000 --> 00:06:16,000 And for just a moment, when you stopped the rotation, I had no idea which way was up. 94 00:06:16,000 --> 00:06:22,000 So you think given all the distractions of car accident, your car going into the drink, there really might be something to this? 95 00:06:22,000 --> 00:06:28,000 Yeah, I mean you're in shock, and given a lack of any prominent cues, I don't think you'd have any way to tell. 96 00:06:28,000 --> 00:06:36,000 That puts confirming the myth right back in play, but it's also Adam's too easy exit that gives him pause for thought. 97 00:06:36,000 --> 00:06:44,000 That tells me something significant. It says that in the interest of eliminating variables, we might have actually created too sterile a testing procedure. 98 00:06:44,000 --> 00:06:51,000 That tells me we need one that's less sterile, we need one that's dirtier, if we need to do this in a real car. 99 00:06:51,000 --> 00:07:00,000 Now to a myth that bids milk against methane, with a gun in between. 100 00:07:00,000 --> 00:07:03,000 Alright, we got an explosive myth this time. 101 00:07:03,000 --> 00:07:04,000 Great. 102 00:07:04,000 --> 00:07:06,000 This one comes from the movie Kiss the Girls. 103 00:07:06,000 --> 00:07:10,000 Cop faces off the bad guy in a kitchen full of gas from the stove. 104 00:07:10,000 --> 00:07:19,000 The cop wants to shoot the bad guy, but the bad guy reminds him, if you shoot me, the muzzle flash from your gun will ignite the gas, blowing up the kitchen and killing them both. 105 00:07:20,000 --> 00:07:26,000 The bad guy's already snapped the gas line, and he's holding a cigarette lighter. 106 00:07:26,000 --> 00:07:32,000 The cop needs to shoot him, but he thinks that the flash from the gun might also ignite the methane. 107 00:07:32,000 --> 00:07:41,000 So he shoots at success through the milk, but can shooting through liquid really stop the muzzle flash from igniting the gas? 108 00:07:41,000 --> 00:07:43,000 Alright, so what's planned? 109 00:07:43,000 --> 00:07:45,000 May I suggest we simply go for it? 110 00:07:45,000 --> 00:07:50,000 I mean, build a kitchen, fill it full of gas, shoot the gun from the movie once into milk, and once not. 111 00:07:50,000 --> 00:07:54,000 That's great, and then we'll see if it does in fact ignite the gas and blow up the kitchen. 112 00:07:57,000 --> 00:08:05,000 So to test the myth that a milk carton will prevent a gun's muzzle flash from igniting a room full of methane, we need to blow up the kitchen. 113 00:08:05,000 --> 00:08:11,000 But since none of us are willing to volunteer our own personal kitchens, we need to build one. 114 00:08:11,000 --> 00:08:14,000 Now we're going to be filling this kitchen up with methane gas. 115 00:08:14,000 --> 00:08:18,000 We don't really know how big of an explosion we're going to get when we ignite the gas. 116 00:08:18,000 --> 00:08:23,000 So we're building the kitchen out of plywood in 2x4s. That way we don't have any metal shrapnel. 117 00:08:23,000 --> 00:08:28,000 But most importantly, one of the walls is going to be made out of a breakaway plexiglass. 118 00:08:28,000 --> 00:08:38,000 So that way we can see what's going on inside the kitchen, and when the gases are ignited, that wall will pop off releasing that pressure wave, so we don't get a huge explosion. 119 00:08:38,000 --> 00:08:43,000 But even a mid-range explosion might just smash the windows and singe the neighbors. 120 00:08:43,000 --> 00:08:49,000 So the kit kitchen is flat-packed and delivered, some assembly required to the local bomb range. 121 00:08:54,000 --> 00:08:59,000 Sometimes the best-order procedure is to just go for it. I mean, find out if we have any merit to the myth at all. 122 00:08:59,000 --> 00:09:04,000 Just straight out to the bomb range, recreate the circumstances, and blow the thing up. 123 00:09:04,000 --> 00:09:07,000 Custom-made cabinets, time to hang them. 124 00:09:07,000 --> 00:09:12,000 To properly restage this movie myth, they'll need more than four walls and a roof. 125 00:09:12,000 --> 00:09:15,000 This is a gorgeous stove-sink combo you've picked out. 126 00:09:15,000 --> 00:09:18,000 We'll be cooking the gas in no time. 127 00:09:18,000 --> 00:09:23,000 With lines like that, you'll need some top-notch actors. And here's our leading man. 128 00:09:23,000 --> 00:09:25,000 Come on, it's time to go to work. 129 00:09:25,000 --> 00:09:29,000 It's hard to believe, but this sack of bones is our Morgan Freeman. 130 00:09:29,000 --> 00:09:32,000 I know. I feel this way every morning, too. 131 00:09:33,000 --> 00:09:34,000 Yeah. 132 00:09:35,000 --> 00:09:39,000 As for Buster, well, he's been tight-cast again. 133 00:09:39,000 --> 00:09:42,000 Okay, handcuffs, just like the guy in the movie. 134 00:09:42,000 --> 00:09:45,000 See that? Looks like I knew what I was doing. 135 00:09:49,000 --> 00:09:57,000 Now they're ready to dial up the danger with things that go bag, the gun, and the gas. 136 00:09:57,000 --> 00:10:02,000 All right, get ready for a big boom. 137 00:10:02,000 --> 00:10:09,000 After the break, we'll see if going straight to a full-scale kitchen was really such a hot idea. 138 00:10:18,000 --> 00:10:26,000 Carrie Grant and Tori are preparing to see if shooting through milk can really stop a gun from igniting a room full of methane. 139 00:10:28,000 --> 00:10:35,000 Now, in the movie, the gas line attached to the stove breaks, so we know it's natural gas. 140 00:10:35,000 --> 00:10:41,000 Now, natural gas is about 85% methane gas, which is very flammable. 141 00:10:41,000 --> 00:10:45,000 But there's a twist. It's only flammable in certain concentrations. 142 00:10:45,000 --> 00:10:51,000 Too little methane means not enough fuel for the fire, but add too much methane, 143 00:10:51,000 --> 00:10:55,000 and there's not enough oxygen molecules to sustain combustion. 144 00:10:55,000 --> 00:11:03,000 The numerical balance of different substances to cause a reaction is called stoichiometry, and Grant's done his homework. 145 00:11:03,000 --> 00:11:08,000 So we know that the perfect stoichiometric ratio of methane in air is 5 to 15%. 146 00:11:08,000 --> 00:11:11,000 So we're going to go right in the middle, say 10%. 147 00:11:11,000 --> 00:11:16,000 With this volume, which is about 500 cubic feet, we're shooting for 50 cubic feet of methane. 148 00:11:16,000 --> 00:11:21,000 With the guys and the gun from the movie and the carton of milk set in place, 149 00:11:21,000 --> 00:11:25,000 we're ready to see if this myth is just Hollywood Hocom. 150 00:11:25,000 --> 00:11:28,000 We're going to fire the gun through the milk and see what happens. 151 00:11:28,000 --> 00:11:36,000 Now, if it works out like the hero thinks and nothing happens, then we're going to try it again, but this time without the milk. 152 00:11:36,000 --> 00:11:39,000 And then we'll see if the room goes up like whoosh. 153 00:11:40,000 --> 00:11:45,000 To get the right balance of methane to air, they turn on the gas for just 90 seconds. 154 00:11:45,000 --> 00:11:49,000 All right, filling up the kitchen with methane gas. 155 00:11:49,000 --> 00:11:51,000 One and a half minutes. 156 00:11:52,000 --> 00:11:58,000 So here's how it stands. If the kitchen explodes, it's an instant and absolute myth busted. 157 00:11:58,000 --> 00:12:02,000 All right, this is methane gas with gun and milk. 158 00:12:02,000 --> 00:12:05,000 In three, two, one. 159 00:12:07,000 --> 00:12:10,000 Well, you shot the milk. 160 00:12:10,000 --> 00:12:11,000 That's for sure. 161 00:12:14,000 --> 00:12:17,000 Explosion. Maybe this myth is true. 162 00:12:17,000 --> 00:12:22,000 So with milk, there was no gas room boom, which is good news for the myth. 163 00:12:22,000 --> 00:12:29,000 But what if the mixture of methane and air was wrong and the room is basically incompressible? 164 00:12:29,000 --> 00:12:36,000 Well, it's easy to test because Grant had the foresight to add a road flare hooked up to an electric match. 165 00:12:36,000 --> 00:12:39,000 Here we go with the flare. Three, two, one. 166 00:12:44,000 --> 00:12:45,000 Hey, we got something. 167 00:12:45,000 --> 00:12:46,000 We got ignition. 168 00:12:46,000 --> 00:12:51,000 The flare not only proves a point, it clears the air of the flammable gas. 169 00:12:52,000 --> 00:12:55,000 So far, it looks like our villain was wrong. 170 00:12:58,000 --> 00:13:01,000 With the gun and the milk, there was no explosion. 171 00:13:01,000 --> 00:13:06,000 But with the gun alone, it sparked a blast anyway. It's time to reload. 172 00:13:07,000 --> 00:13:09,000 All right, so kitchen is filling. 173 00:13:10,000 --> 00:13:14,000 As soon as we hit a minute and 30 seconds, fire the gun. 174 00:13:14,000 --> 00:13:17,000 You think the milk stopped the muzzle flash? You think it's going to explode? 175 00:13:17,000 --> 00:13:19,000 I don't know, but we're about to find out. 176 00:13:19,000 --> 00:13:24,000 We sure are in around about three, two, one. 177 00:13:25,000 --> 00:13:29,000 With the muzzle flash unmuffled by milk, nothing happened. 178 00:13:29,000 --> 00:13:31,000 Okay. All right, no explosion. 179 00:13:31,000 --> 00:13:38,000 If the scene in the movie was based on hard science, that single shot should have triggered a massive explosion. 180 00:13:38,000 --> 00:13:42,000 Now to fire the flare to confirm that the gas mix was right. 181 00:13:45,000 --> 00:13:46,000 Whoa! 182 00:13:47,000 --> 00:13:49,000 So we were at the right ratio. 183 00:13:53,000 --> 00:13:56,000 Yet the bullet did not ignite the methane gas. 184 00:13:56,000 --> 00:14:01,000 Which means the milk did not stop the muzzle flash from lighting the methane gas. 185 00:14:06,000 --> 00:14:12,000 The bad news for this myth is that this did not happen because of muzzle flash from a gun. 186 00:14:12,000 --> 00:14:14,000 This happened because of a flare. 187 00:14:14,000 --> 00:14:19,000 So what we need to do now is figure out what exactly is going on with this myth 188 00:14:19,000 --> 00:14:23,000 and what can possibly cause a roomful of methane to go up. 189 00:14:23,000 --> 00:14:29,000 Up next, Adam and Jamie with a car-sinking rig that should take your breath away. 190 00:14:29,000 --> 00:14:31,000 There's a lot of moving parts to this one. 191 00:14:37,000 --> 00:14:39,000 That pool test was actually pretty interesting. 192 00:14:39,000 --> 00:14:43,000 Yeah, it was. There was just a brief moment when I was distracted by my sinuses 193 00:14:43,000 --> 00:14:45,000 and I honestly didn't know which way was up. 194 00:14:45,000 --> 00:14:49,000 So you think there might actually be something to this story? 195 00:14:49,000 --> 00:14:50,000 Yeah. 196 00:14:50,000 --> 00:14:53,000 Then I don't think there's anything to do now but go full scale. 197 00:14:54,000 --> 00:14:57,000 Adam and Jamie have figured the only fair way to test their myth 198 00:14:57,000 --> 00:15:03,000 is to put Adam inside a real car and drop man and machine in a real lake. 199 00:15:04,000 --> 00:15:10,000 Well, I am standing on the edge of Pit 232, a former quarry lake in sunny Ion, California 200 00:15:10,000 --> 00:15:15,000 which may look familiar to the careful viewer because we shot a couple stories here before. 201 00:15:15,000 --> 00:15:17,000 Right out there in the middle, we did this. 202 00:15:22,000 --> 00:15:24,000 And then right over there is the ramp where we did this. 203 00:15:24,000 --> 00:15:27,000 Now we are about to do this. 204 00:15:27,000 --> 00:15:30,000 All right. I only have a couple more breaths here. 205 00:15:33,000 --> 00:15:36,000 Except this time we are adding an extra wrinkle of jeopardy just to make sure we've covered all our bases. 206 00:15:36,000 --> 00:15:40,000 It's time to sink an upside down car with me in it. 207 00:15:55,000 --> 00:16:00,000 Let's face it, a car like this could only benefit from being dropped in a lake. 208 00:16:00,000 --> 00:16:04,000 Time will tell if the same holds true for Adam. 209 00:16:04,000 --> 00:16:07,000 That's perfect. We can lower it down. 210 00:16:07,000 --> 00:16:12,000 In the interests of relative safety and good science, they won't launch the car, 211 00:16:12,000 --> 00:16:16,000 dukes of hazard style, off a ramp and into the drink. 212 00:16:17,000 --> 00:16:22,000 Instead, to guarantee that the car turns turtle, they'll use a barge, 213 00:16:22,000 --> 00:16:27,000 a tow truck, six empty barrels and more rope than a rodeo. 214 00:16:27,000 --> 00:16:29,000 Here's the plan in a nutshell. 215 00:16:30,000 --> 00:16:35,000 Okay, so we're going to tie a rope to the back bump of our test car on a barge in the middle of the lake. 216 00:16:35,000 --> 00:16:38,000 The other end of that rope goes to a pickup truck on the shore, 217 00:16:38,000 --> 00:16:43,000 which, at the correct signal, will drive forward pulling our test car off the barge. 218 00:16:43,000 --> 00:16:46,000 Now our test car, being a normal car with an engine, is front heavy 219 00:16:46,000 --> 00:16:49,000 and its front will hit the water and start sinking. 220 00:16:49,000 --> 00:16:54,000 What we're hoping is the forward momentum of the pickup truck pulling our test car 221 00:16:54,000 --> 00:16:59,000 from the rear end will actually pull it all the way over until it's upside down. 222 00:16:59,000 --> 00:17:02,000 Just to make sure the car doesn't punch the very bottom of the lake, 223 00:17:02,000 --> 00:17:09,000 we've got six 55 gallon drums making sure that it's secure at a relatively safe depth of 15 feet. 224 00:17:09,000 --> 00:17:13,000 It's as risky a stunt as they've ever attended. 225 00:17:13,000 --> 00:17:16,000 So Jamie's understandably fussing the detail. 226 00:17:16,000 --> 00:17:21,000 Given that this is a one shot deal, we're going to weld guide rails onto this barge 227 00:17:21,000 --> 00:17:25,000 so we know for sure that the car enters the water the way it's supposed to. 228 00:17:25,000 --> 00:17:31,000 Remember, Adam's inside this thing and so if it goes off the barge cockeyed or anything goes wrong, 229 00:17:31,000 --> 00:17:33,000 it might not be pretty. 230 00:17:40,000 --> 00:17:45,000 Equally ugly is the prospect of sinking into the water. 231 00:17:45,000 --> 00:17:48,000 It's the prospect of sinking all the way to the bottom. 232 00:17:48,000 --> 00:17:56,000 They've welded and strapped tight two clusters of three empty barrels to hop the descent at 15 feet under. 233 00:17:56,000 --> 00:18:01,000 Just over the depth with a star report says most cars turn turtle. 234 00:18:01,000 --> 00:18:04,000 Will it work? Let's ask a buoyancy buffon. 235 00:18:04,000 --> 00:18:09,000 Well, our car weighs about 2600 pounds and half of it is tied to the barge I'm standing on 236 00:18:09,000 --> 00:18:13,000 so I only need to support 1300 pounds of the car with these barrels. 237 00:18:13,000 --> 00:18:20,000 Each one of them displaces 440 pounds of water because it pints a pound the world around. 238 00:18:20,000 --> 00:18:25,000 All told, that gives me 2500 pounds of buoyancy for 1300 pounds of car. 239 00:18:25,000 --> 00:18:29,000 That's well within my safety margin. That's enough flotation. 240 00:18:29,000 --> 00:18:35,000 Just like last time, they've removed the engine so oils and sundry fluids don't sully the water. 241 00:18:36,000 --> 00:18:40,000 Making up for the lost mass are 12 barbell weights. 242 00:18:41,000 --> 00:18:43,000 Assuming they ever get there. 243 00:18:43,000 --> 00:18:47,000 Hey Jamie, I need your help. It's too heavy. 244 00:18:47,000 --> 00:18:52,000 I have it on good authority that it's not that bad. Go for it. 245 00:18:52,000 --> 00:18:58,000 But the weight in the barrel is much the same as a whole car engine so Adam wisely resorts to hand delivery. 246 00:18:58,000 --> 00:19:00,000 Last two. Thank you Adam. 247 00:19:00,000 --> 00:19:06,000 That's the last of the heavy lifting and it's time for the SS Poseidon to push off. 248 00:19:07,000 --> 00:19:13,000 Bet if you could see into Jamie's brain right now, he's reminiscing about being a barge driver on the Erie Canal. 249 00:19:13,000 --> 00:19:15,000 Back when at First Ope. 250 00:19:15,000 --> 00:19:19,000 The barge drifts into place at a spot where the water is 50 feet deep. 251 00:19:19,000 --> 00:19:24,000 Adam's next job is to secure those flotation barrels to the car. 252 00:19:24,000 --> 00:19:28,000 Now it's time to attach the lifeline, my safety system. 253 00:19:28,000 --> 00:19:33,000 The four ropes that will suspend this car upside down exactly 15 feet below the surface of the water. 254 00:19:33,000 --> 00:19:39,000 We've isolated that the worst case scenario for this experiment is that the car somehow detaches from all four of its mooring points, 255 00:19:39,000 --> 00:19:46,000 sinks to the bottom upside down so deep in the silty mud that neither my safety diver nor I can open the doors. 256 00:19:46,000 --> 00:19:55,000 If that happens, we will have to sit down there long enough for safety divers with salvage bags to lift the car enough to open the door and free us. 257 00:19:55,000 --> 00:20:01,000 Between you and me, even though we've accommodated for that, I hope it doesn't happen. 258 00:20:01,000 --> 00:20:06,000 Coming up, the rescue crew readies as Adam prepares to take the plunge. 259 00:20:06,000 --> 00:20:11,000 It is now, or never. 260 00:20:19,000 --> 00:20:25,000 Now just to recap, we filled the kitchen with methane gas, fired a gun into milk, it did not ignite the gas. 261 00:20:25,000 --> 00:20:29,000 We removed the milk, fired again, it still did not ignite the gas. 262 00:20:29,000 --> 00:20:38,000 So we need to move on to small scale and find out if it's even possible to ignite methane gas using the muzzle flash from a gun. 263 00:20:38,000 --> 00:20:47,000 Before the milk part of this myth can be restaged, they need to show that a flash from the handgun used in the movie could blow up a room in the first place. 264 00:20:47,000 --> 00:20:51,000 Okay, that's a hole. 265 00:20:51,000 --> 00:21:01,000 It failed on the bomb range, but this test in a bulletproof box filmed in super slow motion should at least shed some light on the subject. 266 00:21:01,000 --> 00:21:06,000 Alright, here's what's going on with the muzzle flash and why it might actually ignite a room full of gas. 267 00:21:06,000 --> 00:21:14,000 Now when a gun is fired, only about 30% of the chemical energy from the propellant is converted to the kinetic energy that is the projectile moving down the barrel. 268 00:21:14,000 --> 00:21:20,000 The rest is contained in the propellant gas particle mixture that escapes from the muzzle of the gun. 269 00:21:20,000 --> 00:21:25,000 A significant portion of that is dissipated into that bright muzzle flash that you see. 270 00:21:25,000 --> 00:21:28,000 Alright, so for this size kitchen, I'm only going to fill it up for two seconds. 271 00:21:28,000 --> 00:21:33,000 Filling up kitchen with methane. 272 00:21:33,000 --> 00:21:34,000 Alright, that should be good. 273 00:21:34,000 --> 00:21:35,000 Carrie counts down. 274 00:21:35,000 --> 00:21:39,000 Shooting the gun in three, two, one. 275 00:21:39,000 --> 00:21:47,000 To another big fat failure. 276 00:21:47,000 --> 00:21:51,000 It takes a keen eye to even spot the muzzle flash. 277 00:21:51,000 --> 00:21:55,000 Alright, so the gun fires and if you look here, there is one frame of muzzle flash. 278 00:21:55,000 --> 00:21:58,000 Yeah, that's only a quarter of a millisecond. 279 00:21:58,000 --> 00:22:03,000 And that's not nearly enough ignition energy to spark a kitchen inferno. 280 00:22:03,000 --> 00:22:05,000 Maybe it's time to upgrade the sidearm. 281 00:22:05,000 --> 00:22:07,000 I want to know if a gun can ignite the gas. 282 00:22:07,000 --> 00:22:09,000 Do you think another gun could do this? 283 00:22:09,000 --> 00:22:10,000 Maybe a hotter load. 284 00:22:10,000 --> 00:22:12,000 Yeah, hotter load, bigger muzzle flash. 285 00:22:12,000 --> 00:22:14,000 Sure, that might work. 286 00:22:14,000 --> 00:22:15,000 Let's try it. 287 00:22:16,000 --> 00:22:22,000 A hot load means more powder in the cartridge, but there's also a very good reason to switch guns. 288 00:22:22,000 --> 00:22:27,000 We're having no luck igniting our gas with the gun the hero carried around in the movie. 289 00:22:27,000 --> 00:22:29,000 But there's a little Hollywood mistake here. 290 00:22:29,000 --> 00:22:34,000 Though the hero was carrying a sick sour throughout the entire movie, the villain said he was holding a Glock. 291 00:22:34,000 --> 00:22:36,000 So that's what we're testing next. 292 00:22:36,000 --> 00:22:39,000 And just for good measure, we're using a hotter load. 293 00:22:39,000 --> 00:22:42,000 The hot load is called a plus P. 294 00:22:42,000 --> 00:22:46,000 So let's see if a new round and the right gun can get the job done. 295 00:22:46,000 --> 00:22:48,000 Okay, loaded. 296 00:22:51,000 --> 00:22:52,000 Alright, we're hot. 297 00:22:52,000 --> 00:22:54,000 Alright. 298 00:22:54,000 --> 00:22:55,000 Okay, it's ready. 299 00:22:55,000 --> 00:22:57,000 Here we go. 300 00:22:57,000 --> 00:22:59,000 In three, two, one. 301 00:23:02,000 --> 00:23:04,000 Again, no explosion. 302 00:23:04,000 --> 00:23:08,000 So Carrie burns off the gas with an electric match. 303 00:23:10,000 --> 00:23:16,000 Now it's back to the high speed to check what was way too quick for the naked eye. 304 00:23:16,000 --> 00:23:19,000 Wow, look at how much bigger the muzzle flash is. 305 00:23:19,000 --> 00:23:21,000 Yeah, but we still didn't get ignition. 306 00:23:21,000 --> 00:23:23,000 So it's not looking so good for the movie myth. 307 00:23:23,000 --> 00:23:26,000 But I really do want to see a gun light the gas. 308 00:23:26,000 --> 00:23:28,000 I think we're going to need a bigger gun. 309 00:23:28,000 --> 00:23:30,000 And possibly an even hotter load. 310 00:23:32,000 --> 00:23:36,000 And this being Mythbusters, we do have some options. 311 00:23:36,000 --> 00:23:37,000 We're going big. 312 00:23:37,000 --> 00:23:39,000 Really big. 313 00:23:39,000 --> 00:23:41,000 44 Magnum big. 314 00:23:41,000 --> 00:23:44,000 As we found in Adam and Jamie's Myth Handgun Horror, 315 00:23:44,000 --> 00:23:46,000 the flash comes not only out of the muzzle, 316 00:23:46,000 --> 00:23:48,000 but here where the cylinder is. 317 00:23:52,000 --> 00:23:54,000 When you need significant muzzle flash, 318 00:23:54,000 --> 00:23:57,000 this is what you call on. 319 00:23:57,000 --> 00:24:00,000 It stands to reason that this round in this gun 320 00:24:00,000 --> 00:24:03,000 should spark the biggest flash so far. 321 00:24:03,000 --> 00:24:06,000 And right now, it's all about igniting the gas. 322 00:24:07,000 --> 00:24:10,000 All right, guns loaded and cocked. 323 00:24:12,000 --> 00:24:14,000 Of course, if this fails, well, 324 00:24:14,000 --> 00:24:18,000 it might be time to have a stern word with the screenwriter. 325 00:24:19,000 --> 00:24:20,000 Okay, ready? 326 00:24:20,000 --> 00:24:23,000 Shooting in three, two, one. 327 00:24:27,000 --> 00:24:28,000 Dang. 328 00:24:28,000 --> 00:24:30,000 No ignition. 329 00:24:30,000 --> 00:24:32,000 Man, that was a big muzzle flash. 330 00:24:32,000 --> 00:24:34,000 All right, let's go check out the high speed. 331 00:24:35,000 --> 00:24:36,000 Good thinking. 332 00:24:36,000 --> 00:24:38,000 There's nothing like watching your feathers 333 00:24:38,000 --> 00:24:40,000 in super slow motion. 334 00:24:41,000 --> 00:24:44,000 Even with the larger load, which has more powder, 335 00:24:44,000 --> 00:24:46,000 we're still not able to ignite the methane. 336 00:24:46,000 --> 00:24:48,000 So I think we moved past the moving myth at this point. 337 00:24:48,000 --> 00:24:50,000 I think we need the essence of this myth, 338 00:24:50,000 --> 00:24:53,000 which is that a gun can light a room full of gas 339 00:24:53,000 --> 00:24:55,000 and that milk can stop it. 340 00:24:55,000 --> 00:24:56,000 So where do we go? 341 00:24:56,000 --> 00:24:58,000 The myth is busted. 342 00:24:58,000 --> 00:25:01,000 Not even the 44 Magnum could spark the methane, 343 00:25:01,000 --> 00:25:04,000 but the team still has high hopes of a gunshot 344 00:25:04,000 --> 00:25:06,000 exploding a room full of gas. 345 00:25:06,000 --> 00:25:09,000 If they manage to do that, they're right back on track 346 00:25:09,000 --> 00:25:14,000 to see if a carton of ordinary milk can prevent a catastrophe. 347 00:25:20,000 --> 00:25:25,000 Back on the barge, Adam's immersed in a tangle of sheep shanks and bow lines. 348 00:25:26,000 --> 00:25:29,000 If it looks like a lonely pursuit, you're right. 349 00:25:29,000 --> 00:25:32,000 But he's not doing this just to calm his nerves. 350 00:25:32,000 --> 00:25:34,000 Well, not exactly. 351 00:25:34,000 --> 00:25:36,000 Why am I doing all this by myself? 352 00:25:36,000 --> 00:25:39,000 Well, to me, it's axiomatic. 353 00:25:39,000 --> 00:25:44,000 If your life depends upon the rigging, do your rigging. 354 00:25:46,000 --> 00:25:49,000 While I'm sitting there waiting for this car to drop over the edge, 355 00:25:49,000 --> 00:25:53,000 I'm going to be going through the rigging in my mind about a hundred times. 356 00:25:53,000 --> 00:25:56,000 And I'm going to want to be able to picture the whole thing in my brain. 357 00:25:56,000 --> 00:25:58,000 So I might as well do it myself. 358 00:25:59,000 --> 00:26:02,000 I'm going to be able to picture the whole thing in my mind about a hundred times. 359 00:26:09,000 --> 00:26:14,000 That not right there is going to pull this car to its final resting place. 360 00:26:14,000 --> 00:26:16,000 But hopefully not me. 361 00:26:19,000 --> 00:26:23,000 Worst case scenario here is that both Adam and our safety diver get knocked out cold 362 00:26:23,000 --> 00:26:26,000 from all of this violence and this impact. 363 00:26:27,000 --> 00:26:32,000 I don't think that's going to happen, but that would be a bad thing if it does. 364 00:26:32,000 --> 00:26:34,000 Bad enough of the doom and gloom. 365 00:26:34,000 --> 00:26:37,000 The whole point of this test is to save lives. 366 00:26:37,000 --> 00:26:40,000 If and when the unthinkable happens to you. 367 00:26:40,000 --> 00:26:44,000 We've already done a full episode on a car going into the water. 368 00:26:46,000 --> 00:26:47,000 Here we go. 369 00:26:47,000 --> 00:26:51,000 We're over an episode that is one of, I think, our proudest moments. 370 00:26:51,000 --> 00:26:55,000 Given that four separate fans have written to us and said that watching that episode 371 00:26:55,000 --> 00:26:59,000 gave them critical information that allowed them to escape when their car went underwater. 372 00:27:01,000 --> 00:27:03,000 Well, it's because of Turning Turtle. 373 00:27:03,000 --> 00:27:08,000 It's because fans wrote to us and said that most cars going in the water turn completely over. 374 00:27:08,000 --> 00:27:13,000 And even though we've sunk a car in the water a dozen times, we wanted to know what happens 375 00:27:13,000 --> 00:27:15,000 when that car goes completely upside down. 376 00:27:15,000 --> 00:27:18,000 Do you become so disoriented that it becomes much harder to escape? 377 00:27:18,000 --> 00:27:20,000 And how then do you escape? 378 00:27:20,000 --> 00:27:22,000 That's what we're going to answer with this setup. 379 00:27:22,000 --> 00:27:30,000 If the myth is correct, at Escape is Impossible, emergency air supplies are fitted for and asked. 380 00:27:30,000 --> 00:27:32,000 That's good. 381 00:27:32,000 --> 00:27:35,000 Alright, I'm going to turn this off for right now. 382 00:27:35,000 --> 00:27:36,000 Yeah. 383 00:27:36,000 --> 00:27:37,000 And I'm going to turn it on. 384 00:27:37,000 --> 00:27:38,000 I will. 385 00:27:38,000 --> 00:27:39,000 Okay. 386 00:27:39,000 --> 00:27:41,000 I think we're pretty much ready to go. 387 00:27:41,000 --> 00:27:42,000 I don't think that's going anywhere. 388 00:27:42,000 --> 00:27:43,000 I don't think so. 389 00:27:43,000 --> 00:27:45,000 Except into the water with you. 390 00:27:53,000 --> 00:27:57,000 Sliding into the backseat is Diver Dawn. 391 00:27:57,000 --> 00:28:01,000 If things really go badly, he's there to save Adam's life. 392 00:28:01,000 --> 00:28:05,000 This is meant to be much harder than when he was right side up. 393 00:28:05,000 --> 00:28:12,000 And once again, he'll wrench on the doors, maybe kick at the windows and try to stay calm. 394 00:28:12,000 --> 00:28:14,000 So what are the various outcomes likely to mean in this test? 395 00:28:14,000 --> 00:28:20,000 Well, if I get to the surface by either breaking the window or resorting to breathable air, 396 00:28:20,000 --> 00:28:22,000 then I would say the fans are totally right. 397 00:28:22,000 --> 00:28:27,000 However, if I'm able to maintain my cool and actually get to the surface without breaking the window, 398 00:28:27,000 --> 00:28:30,000 without resorting to air just by holding my breath and staying calm, 399 00:28:30,000 --> 00:28:32,000 then I would say that the fans are wrong. 400 00:28:32,000 --> 00:28:37,000 And in either case, we have illuminated a whole new feature of cars going into water. 401 00:28:37,000 --> 00:28:40,000 Straight ahead, the perils of cooking with hydrogen. 402 00:28:40,000 --> 00:28:42,000 Holy moly. 403 00:28:42,000 --> 00:28:45,000 But can milk still save the day? 404 00:28:50,000 --> 00:28:56,000 3, 2, 1, go! 405 00:28:56,000 --> 00:29:03,000 In the myth of the gas room boom, pure methane has proved, well, let's say, uncooperative. 406 00:29:03,000 --> 00:29:08,000 Okay, methane's not exploding, but that's a good thing because it's in people's houses. 407 00:29:08,000 --> 00:29:12,000 I don't think this myth is actually going to get anywhere unless we move on to a more explosive gas. 408 00:29:12,000 --> 00:29:16,000 What about hydrogen? It's got a lower ignition energy than methane, 1.15, 409 00:29:16,000 --> 00:29:20,000 and its flammability range in air is 5 to 75%. 410 00:29:20,000 --> 00:29:23,000 Roomful gas, all that. 411 00:29:23,000 --> 00:29:28,000 Remember, the myth that they're trying to test is if milk can suppress a muzzle flash 412 00:29:28,000 --> 00:29:31,000 and prevent an explosion of volatile gas. 413 00:29:31,000 --> 00:29:36,000 But with methane, the gas used in the movie, they got nowhere fast. 414 00:29:36,000 --> 00:29:39,000 So now, they've changed up to hydrogen. 415 00:29:39,000 --> 00:29:45,000 Now, in these next tests, we're going to use the same guns, the 9mm Glock and the 9mm Sig Sauer, 416 00:29:45,000 --> 00:29:47,000 plus the 44 Magnum. 417 00:29:47,000 --> 00:29:49,000 The only thing that's going to change this time is the gas. 418 00:29:49,000 --> 00:29:55,000 We're using hydrogen. It's more flammable, so hopefully one of these will get that gas to ignite. 419 00:29:55,000 --> 00:30:00,000 Starting off with a Sig Sauer, they're trying to find the perfect gun and round combination. 420 00:30:00,000 --> 00:30:04,000 Alright, we're locked lowly to ignite the gas without milk, 421 00:30:04,000 --> 00:30:07,000 and then add the milk to see if it stops the explosion. 422 00:30:07,000 --> 00:30:09,000 Alright, filling the tank. 423 00:30:09,000 --> 00:30:16,000 Okay, you fire, and then I'm going to flame if it doesn't ignite. 424 00:30:16,000 --> 00:30:19,000 Here we go. In three, two, one. 425 00:30:23,000 --> 00:30:26,000 Oh my gosh, it just ignited the gas. 426 00:30:26,000 --> 00:30:28,000 I can't tell. I think we need to check the high speed. 427 00:30:28,000 --> 00:30:33,000 Always a good plan, as Tori's wishful thinking comes to nothing. 428 00:30:33,000 --> 00:30:36,000 The gun went off, the gas didn't. 429 00:30:36,000 --> 00:30:41,000 Even with the more flammable gas, it still was not enough to be ignited by the muzzle flash. 430 00:30:41,000 --> 00:30:43,000 Hey, we're just starting. We got another gun. 431 00:30:43,000 --> 00:30:44,000 Alright. 432 00:30:44,000 --> 00:30:51,000 So next up is the gun they said they used in the movie, but actually didn't, the Glock 17. 433 00:30:51,000 --> 00:30:56,000 Alright, so we are about to fire a high velocity round out of a Glock into the hydrogen. 434 00:30:56,000 --> 00:31:01,000 Now, we saw when we fired it into the methane that the higher velocity round had a bigger muzzle flash, 435 00:31:01,000 --> 00:31:05,000 but I still don't think it's going to be enough to ignite that hydrogen gas. 436 00:31:05,000 --> 00:31:10,000 If Tori's right, this myth might soon die with a whimper, not a bang. 437 00:31:10,000 --> 00:31:13,000 Grant agrees, and he's worked up a theory. 438 00:31:13,000 --> 00:31:18,000 What I think is happening is there's a pressure wave that's pushing all the gas out of the way, 439 00:31:18,000 --> 00:31:22,000 and the part that might ignite it is never meeting the gas. 440 00:31:22,000 --> 00:31:25,000 So, you know what? I think this is never going to happen. 441 00:31:25,000 --> 00:31:28,000 But you know what they say about famous last words. 442 00:31:28,000 --> 00:31:29,000 What? 443 00:31:29,000 --> 00:31:36,000 I think that ignited the gas. 444 00:31:36,000 --> 00:31:40,000 Holy moly! 445 00:31:40,000 --> 00:31:43,000 Didn't see that one coming. 446 00:31:49,000 --> 00:31:54,000 Oh my gosh, this myth is looking very plausible. 447 00:31:54,000 --> 00:31:55,000 I guess I was wrong. 448 00:31:55,000 --> 00:32:00,000 There's no doubt that was a blast and a half. 449 00:32:00,000 --> 00:32:04,000 The tank is in pieces, and so is the high speed camera. 450 00:32:04,000 --> 00:32:07,000 There is a lot of energy right there. 451 00:32:07,000 --> 00:32:10,000 But did you see that? It's incredible. 452 00:32:10,000 --> 00:32:15,000 The gas was ignited from the muzzle flash. 453 00:32:18,000 --> 00:32:21,000 All I know is when Kerry pulled the trigger, 454 00:32:21,000 --> 00:32:25,000 the blast was so large that I was stunned. 455 00:32:25,000 --> 00:32:28,000 I didn't know what to say. I was just sitting there blinking. 456 00:32:30,000 --> 00:32:34,000 So they finally nailed the right bullet, the gun and the gas. 457 00:32:34,000 --> 00:32:38,000 But it still bodes no good for that key scene from Kiss the Girls. 458 00:32:38,000 --> 00:32:42,000 Well, it's busted as far as the movie goes, because nobody's cooking with hydrogen. 459 00:32:42,000 --> 00:32:48,000 But the question is, if the essence of this myth is gun igniting gas, can milk stop that? 460 00:32:48,000 --> 00:32:51,000 Maybe we should clean up, reset and try some milk. 461 00:32:51,000 --> 00:32:54,000 We definitely have to take this full scale. 462 00:32:54,000 --> 00:33:01,000 But filling a full-sized room would take 75 times more hydrogen than they used in the small tank. 463 00:33:01,000 --> 00:33:04,000 And that's way too dangerous, even for us. 464 00:33:04,000 --> 00:33:07,000 So the boys have gone mid-scale. 465 00:33:07,000 --> 00:33:12,000 Not too big, not too small, and not too shabby. 466 00:33:13,000 --> 00:33:16,000 Check it out, Kerry. We made you a dollhouse. 467 00:33:16,000 --> 00:33:17,000 Oh my gosh. 468 00:33:17,000 --> 00:33:20,000 We're going to fill up with hydrogen and blow up. 469 00:33:20,000 --> 00:33:23,000 Oh my gosh, I want to keep this.
