1 00:00:00,000 --> 00:00:04,520 Give us a break. 2 00:00:04,520 --> 00:00:10,640 Don't try what you're about to see at home. 3 00:00:10,640 --> 00:00:15,520 On this episode of MythBusters, Jamie and Adam get that sinking feeling. 4 00:00:15,520 --> 00:00:16,520 Oh man. 5 00:00:16,520 --> 00:00:19,200 Oh that sound is so long. 6 00:00:19,200 --> 00:00:22,840 To test the myth that if your vehicle plunges into the drink. 7 00:00:22,840 --> 00:00:24,760 Oh my god it's coming up in the air. 8 00:00:24,760 --> 00:00:26,560 Wow, can you feel the pressure? 9 00:00:26,560 --> 00:00:30,400 Are you done or is there a way to escape? 10 00:00:30,400 --> 00:00:33,000 That is intense. 11 00:00:33,000 --> 00:00:36,640 And meanwhile, in the biggest build of its kind in history. 12 00:00:36,640 --> 00:00:39,440 This is going to be the biggest piece of paper ever. 13 00:00:39,440 --> 00:00:42,480 Grant, Tori and Carrie attempt to squash the myth. 14 00:00:42,480 --> 00:00:44,560 Put it on the pancake. 15 00:00:44,560 --> 00:00:49,760 That it's an impossible task to fold a piece of paper more than seven times. 16 00:00:49,760 --> 00:00:55,400 So he sounded so much easier on paper. 17 00:00:56,400 --> 00:01:00,200 Who are the MythBusters? 18 00:01:00,200 --> 00:01:01,200 Adam Savage. 19 00:01:01,200 --> 00:01:02,200 Ow ow ow. 20 00:01:02,200 --> 00:01:04,720 And Jamie Heidemann. 21 00:01:04,720 --> 00:01:06,640 It's almost too exciting. 22 00:01:06,640 --> 00:01:11,800 Between them more than 30 years of special effects experience. 23 00:01:11,800 --> 00:01:13,640 Queue, dramatic music. 24 00:01:13,640 --> 00:01:15,640 Joining them, Carrie Byron. 25 00:01:15,640 --> 00:01:17,320 That's going to be so cool. 26 00:01:17,320 --> 00:01:18,320 Grant Imahara. 27 00:01:18,320 --> 00:01:20,680 Listen to that baby purr. 28 00:01:20,680 --> 00:01:21,680 And Tori Bellachy. 29 00:01:21,680 --> 00:01:24,320 Charamedics are nowhere to be found. 30 00:01:24,320 --> 00:01:26,880 They don't just tell the myths. 31 00:01:26,880 --> 00:01:30,680 They put them to the test. 32 00:01:44,680 --> 00:01:46,440 Underwater car escape. 33 00:01:46,440 --> 00:01:49,720 Something tells me this involves a car in the water. 34 00:01:49,720 --> 00:01:51,680 Shockingly, that is true. 35 00:01:51,680 --> 00:01:55,200 This is what I've been wanting to do almost since we started doing this show. 36 00:01:55,200 --> 00:01:59,000 The myth is that you're in a car, it goes over the side of a branch or something into 37 00:01:59,000 --> 00:02:00,920 the water and starts to sink. 38 00:02:00,920 --> 00:02:05,080 The myth is you will not be able to open that door until the cabin of the car fills up with 39 00:02:05,080 --> 00:02:08,240 water and then you can open the door and escape. 40 00:02:08,240 --> 00:02:10,600 Sounds like you might be cutting that kind of close though. 41 00:02:10,600 --> 00:02:12,960 That's exactly what we're going to find out. 42 00:02:12,960 --> 00:02:18,760 It's the stuff of nightmares and spectacular movie stunts. 43 00:02:18,760 --> 00:02:22,720 But this sinking scenario is a real life life threat. 44 00:02:22,720 --> 00:02:27,160 So if you're in a vehicle that takes a dive into the drink, is it possible to escape 45 00:02:27,160 --> 00:02:31,120 or would a watery grave be your fate? 46 00:02:31,120 --> 00:02:34,360 I think it's pretty obvious what the plan for this one should be. 47 00:02:34,360 --> 00:02:39,320 Yep, we've got to get a real car, we've got to put it in the water and get inside it and 48 00:02:39,320 --> 00:02:40,320 go down with it. 49 00:02:40,320 --> 00:02:41,800 I've always wanted to be the dude in the car. 50 00:02:41,800 --> 00:02:43,080 You've got to let me be the dude in the car. 51 00:02:43,080 --> 00:02:44,480 You can be the dude in the car. 52 00:02:44,480 --> 00:02:45,480 Yes! 53 00:02:45,480 --> 00:02:47,640 Dude, better you than me. 54 00:02:47,640 --> 00:02:52,440 But before he gets his feet wet, Adam first sets up a small scale pressure test. 55 00:02:52,440 --> 00:02:55,640 He fills a three foot deep cylindrical tank with water. 56 00:02:55,640 --> 00:03:01,520 It's an interestingly improvised rubbery contrivance that makes perfect sense to him. 57 00:03:01,520 --> 00:03:07,200 On the right here is a box which represents my car and like a car it will let water in 58 00:03:07,200 --> 00:03:11,280 but slowly it will leak out of a lot of the corners and edges. 59 00:03:11,280 --> 00:03:16,720 And when you see that happening, hopefully this unit will demonstrate that the pressure 60 00:03:16,720 --> 00:03:21,440 is higher here on this drum that's in the open water than it is on this drum that's 61 00:03:21,440 --> 00:03:22,440 in the car. 62 00:03:22,440 --> 00:03:27,480 Adam places a small piece of perspex loosely on the underside of the box that will represent 63 00:03:27,480 --> 00:03:29,600 the door of his car. 64 00:03:29,600 --> 00:03:30,600 Ready? 65 00:03:30,600 --> 00:03:31,600 Yep. 66 00:03:31,600 --> 00:03:35,560 Each foot the drum is lowered is equivalent to half a PSI of pressure. 67 00:03:35,560 --> 00:03:41,440 In the real world that's a crushing one to two thousand pounds of force on a door. 68 00:03:41,440 --> 00:03:44,920 That's the pressure inside the car, that's the pressure of the water outside the car. 69 00:03:44,920 --> 00:03:49,360 When you're inside this car you're trying to open this door you can't because the pressure 70 00:03:49,360 --> 00:03:51,880 outside is higher than the pressure inside. 71 00:03:51,880 --> 00:03:53,040 Pressure differential. 72 00:03:53,040 --> 00:03:55,760 It's happening. 73 00:03:55,760 --> 00:04:00,280 Pressure differential occurs because water exerts greater pressure than air. 74 00:04:00,280 --> 00:04:04,600 When a vehicle sinks the water presses on the doors holding them shut. 75 00:04:04,600 --> 00:04:09,400 When the cabin fills with water the inside pressure becomes the same as the outside and 76 00:04:09,400 --> 00:04:12,960 it's only then its grip is released. 77 00:04:12,960 --> 00:04:17,280 After building up and up the two lines finally meet. 78 00:04:17,280 --> 00:04:19,040 Watch the store, watch the store. 79 00:04:19,040 --> 00:04:20,040 And release. 80 00:04:20,040 --> 00:04:21,040 Ha ha ha! 81 00:04:21,040 --> 00:04:25,640 There it goes. 82 00:04:25,640 --> 00:04:31,240 To test this theory in a real life situation the plan is to suspend a car from a crane. 83 00:04:31,240 --> 00:04:35,960 Adam will be the trap driver in front while Jamie will be in back wearing a rebreather. 84 00:04:35,960 --> 00:04:41,120 Then the car will be lowered into the watery depths with safety divers monitoring the entire 85 00:04:41,120 --> 00:04:42,120 operation. 86 00:04:42,120 --> 00:04:49,360 Fresh from the classifies Jamie has found a classic American sedan with power windows. 87 00:04:49,360 --> 00:04:50,880 It runs great. 88 00:04:50,880 --> 00:04:52,760 Never to start again. 89 00:04:52,760 --> 00:04:55,120 Now to pull it apart. 90 00:04:55,120 --> 00:04:59,800 First thing we need to do is remove the engine from the car because any oil, any fluids that 91 00:04:59,800 --> 00:05:02,200 would foul the water is going to be a problem. 92 00:05:02,200 --> 00:05:05,200 What's the matter? 93 00:05:05,200 --> 00:05:10,360 Haven't you ever seen somebody work on a car with an ax? 94 00:05:10,360 --> 00:05:14,800 His opponent has been wounded and is starting to weaken. 95 00:05:14,800 --> 00:05:17,840 It's coming. 96 00:05:17,840 --> 00:05:23,720 After a protracted battle the engine finally succones. 97 00:05:23,720 --> 00:05:27,920 Jamie is victorious but the thrill of the kill has gone to his head. 98 00:05:27,920 --> 00:05:34,200 I had to remove the engine from the car to clean the car up so I did. 99 00:05:34,200 --> 00:05:39,240 Well, there's your problem. 100 00:05:40,240 --> 00:05:46,360 Now that the engine is out he needs to add its equivalent weight back in. 101 00:05:46,360 --> 00:05:49,040 This thing right here is our engine surrogate. 102 00:05:49,040 --> 00:05:53,920 We need to simulate the amount of weight that it represented because the car might settle 103 00:05:53,920 --> 00:05:56,440 into the water differently if we don't. 104 00:05:56,440 --> 00:06:00,880 700 pounds of weight is lowered into the cavity. 105 00:06:00,880 --> 00:06:06,560 This is Jamie's new hydrogen fuel cell engine. 106 00:06:06,560 --> 00:06:11,280 With the weighting checked off it's time to make like Keith Moon and drive the car 107 00:06:11,280 --> 00:06:12,840 into the pool. 108 00:06:12,840 --> 00:06:18,160 To conduct their test, Campolindo High School in Marega is kindly letting us use their aquatic 109 00:06:18,160 --> 00:06:19,160 center. 110 00:06:19,160 --> 00:06:20,800 Go Cougars! 111 00:06:20,800 --> 00:06:25,280 This is a high school diving pool and this is where we're going to sink our car. 112 00:06:25,280 --> 00:06:29,880 It's about 13 feet deep right here which should be plenty for us to do our test. 113 00:06:29,880 --> 00:06:31,280 It's nice and warm. 114 00:06:31,280 --> 00:06:33,520 It'll be great. 115 00:06:33,640 --> 00:06:39,680 Aside from his burning enthusiasm, Adam has a burning question for safety diver Sean. 116 00:06:39,680 --> 00:06:41,720 Alright Sean, so I'm going to be in this car. 117 00:06:41,720 --> 00:06:44,000 It's going to start filling up with water. 118 00:06:44,000 --> 00:06:48,000 I'm going to hold my breath but when I run out what's the backup? 119 00:06:48,000 --> 00:06:51,520 Well the backup is sitting in your passenger seat right there. 120 00:06:51,520 --> 00:06:52,520 This back up. 121 00:06:52,520 --> 00:06:56,080 We're going to keep a feet of air waiting for you with a five foot long hose. 122 00:06:56,080 --> 00:06:58,720 Remember to purge it and breathe normally. 123 00:06:58,720 --> 00:07:00,720 That's already hooked up. 124 00:07:00,720 --> 00:07:02,520 It's ready to go. 125 00:07:02,520 --> 00:07:07,280 And Jamie will be sitting here in his re-breather with this standing bind case I need it. 126 00:07:07,280 --> 00:07:08,280 Correct. 127 00:07:08,280 --> 00:07:10,080 Jamie isn't in the back just to look pretty. 128 00:07:10,080 --> 00:07:16,200 He's a certified dive master with 30 years of experience and 3,000 dives under his weight 129 00:07:16,200 --> 00:07:17,200 belt. 130 00:07:17,200 --> 00:07:20,040 I'm just going to be sitting there relaxing waiting for Adam to freak out and then I'll 131 00:07:20,040 --> 00:07:21,920 be right there with his regulator. 132 00:07:21,920 --> 00:07:27,320 So as not to skew the test by adding extra air, Jamie will be using a re-breather instead 133 00:07:27,320 --> 00:07:29,920 of regular scuba tanks. 134 00:07:29,920 --> 00:07:34,280 His recycle exhaled breath and therefore don't create bubbles. 135 00:07:34,280 --> 00:07:39,080 It's a self-contained unit that's very 007. 136 00:07:39,080 --> 00:07:41,720 Adam's starting to lose his cool. 137 00:07:41,720 --> 00:07:46,520 I'm actually a little freaked out because I'm going to be like holding myself up off 138 00:07:46,520 --> 00:07:47,520 the dashboard. 139 00:07:47,520 --> 00:07:51,200 I'll be my face planted into the windshield in this thing. 140 00:07:51,200 --> 00:07:55,400 I didn't take that into account and it's going to make this a lot more difficult to stay 141 00:07:55,400 --> 00:07:57,280 focused and calm. 142 00:07:57,280 --> 00:07:58,880 Let's go do it. 143 00:07:58,880 --> 00:08:06,840 The safety divers swim into position and Jamie has some final sage words of advice. 144 00:08:06,840 --> 00:08:10,720 Adam, I only have one thing to say to you. 145 00:08:10,720 --> 00:08:14,600 Don't pee in the pool because I'm in the car there with you. 146 00:08:14,600 --> 00:08:18,280 Time for Adam to get inside for the ride of his life. 147 00:08:18,280 --> 00:08:20,720 You ready? 148 00:08:20,720 --> 00:08:25,760 All set. 149 00:08:25,760 --> 00:08:32,440 So wearing no scuba gear, 13 feet underwater, does Adam think he'll sink or swim? 150 00:08:32,440 --> 00:08:36,760 I think it's entirely likely I may need oxygen before this test is complete. 151 00:08:36,760 --> 00:08:39,160 Okay, getting into gear. 152 00:08:39,160 --> 00:08:41,160 Is that a problem? 153 00:08:41,160 --> 00:08:44,680 Next, Adam is flooded with strong emotions. 154 00:08:44,680 --> 00:08:45,680 Oh, sh**. 155 00:08:45,680 --> 00:08:46,680 Oh, man. 156 00:08:46,680 --> 00:08:50,680 Oh, sh**. 157 00:08:50,680 --> 00:08:53,800 And coming up, the team makes a super-sized spreadsheet. 158 00:08:53,840 --> 00:08:58,160 This is going to be the biggest piece of paper ever. 159 00:08:58,160 --> 00:09:02,840 Jamie and Adam are testing the myth that if your car swerves off the road and into a body 160 00:09:02,840 --> 00:09:08,400 of water to get out alive, you have to wait until it's completely submerged and full of 161 00:09:08,400 --> 00:09:10,600 water before you can open the door. 162 00:09:10,600 --> 00:09:16,240 So did you know last year, AAA estimated 11,000 vehicles went off the road and into 163 00:09:16,240 --> 00:09:20,000 the water and as a result of those accidents, 300 people died? 164 00:09:20,000 --> 00:09:21,000 I only count. 165 00:09:21,000 --> 00:09:22,000 That's a lot of people. 166 00:09:22,000 --> 00:09:23,920 I thought it was more like a freak accident. 167 00:09:23,920 --> 00:09:26,080 Now, apparently it's a lot more common than that. 168 00:09:26,080 --> 00:09:34,160 Well, maybe we can help raise awareness a bit as to what these people are facing. 169 00:09:34,160 --> 00:09:39,680 And what better way to raise awareness than to raise themselves in a car, into the sky, 170 00:09:39,680 --> 00:09:41,680 and plunge into a pool? 171 00:09:41,680 --> 00:09:45,200 What the f**k are we doing? 172 00:09:45,200 --> 00:09:51,280 Remember, when Adam goes 13 feet under, he won't be wearing breathing apparatus. 173 00:09:51,280 --> 00:09:58,240 The paramedics are on their toes and Adam has his escape strategy all worked out. 174 00:09:58,240 --> 00:10:04,200 I'm going to try to start opening this door the moment I see the water get above my glass. 175 00:10:04,200 --> 00:10:08,520 Now if the myth is true, I won't be able to open that door until the water level inside 176 00:10:08,520 --> 00:10:11,320 the car gets to the same point. 177 00:10:11,320 --> 00:10:12,520 Deep breaths, Adam. 178 00:10:12,520 --> 00:10:13,680 Deep breaths. 179 00:10:13,680 --> 00:10:16,760 It's way too late to put on the brakes. 180 00:10:16,760 --> 00:10:19,160 I couldn't stop now from one or two. 181 00:10:19,160 --> 00:10:22,880 As the water rushes in, Adam is getting that sinking feeling. 182 00:10:22,880 --> 00:10:24,880 Oh, s**t. 183 00:10:24,880 --> 00:10:26,880 Oh, man. 184 00:10:26,880 --> 00:10:29,080 Oh, s**t. 185 00:10:29,080 --> 00:10:32,760 The crane chains go slack and the car is sinking on its own. 186 00:10:32,760 --> 00:10:39,960 The 700-pound fake engine is taking it down nose first, exactly as it would in a real situation. 187 00:10:39,960 --> 00:10:44,280 The water's up to my butt now. 188 00:10:44,280 --> 00:10:45,280 All right. 189 00:10:45,280 --> 00:10:47,640 Okay, it's coming past my waist. 190 00:10:47,640 --> 00:10:49,400 Now I can start to see under the water. 191 00:10:49,400 --> 00:10:50,400 Oh, my God. 192 00:10:50,400 --> 00:10:51,400 It's coming up under the windshield. 193 00:10:51,400 --> 00:10:52,400 Wow, I can feel the pressure. 194 00:10:52,400 --> 00:10:53,400 All right. 195 00:10:53,400 --> 00:10:59,760 I only have a couple more breaths here. 196 00:10:59,760 --> 00:11:04,240 Adam's never this quiet, so what's going on down there? 197 00:11:04,240 --> 00:11:09,960 The water is leaking in from every open crevice in the car and Adam is now fully under. 198 00:11:09,960 --> 00:11:15,960 He holds his breath, tugs on the door, pushes his whole weight against it, but nothing 199 00:11:15,960 --> 00:11:16,960 happens. 200 00:11:16,960 --> 00:11:27,320 Finally, he can't hold his breath any longer and signals for Jamie to pass in the regulator. 201 00:11:27,320 --> 00:11:32,880 When the pressure ultimately equalizes, he opens the door and swims to the surface, but 202 00:11:32,880 --> 00:11:34,880 it was too late. 203 00:11:34,880 --> 00:11:48,680 That is intense. 204 00:11:48,680 --> 00:11:52,360 No matter how you slice it. 205 00:11:52,360 --> 00:11:53,360 I died. 206 00:11:53,360 --> 00:11:54,960 Let's just put it that way. 207 00:11:54,960 --> 00:11:57,560 Well, that's put a dampener on things. 208 00:11:57,560 --> 00:12:02,240 From the time the water hit Adam's knees to when he surfaced, took just one minute and 209 00:12:02,240 --> 00:12:05,920 51 seconds, but that's a long time when you're drowning. 210 00:12:05,920 --> 00:12:09,800 The fact is, even though you do go vertical, you don't feel like it because the water is 211 00:12:09,800 --> 00:12:11,520 filling the cabin at that point. 212 00:12:11,520 --> 00:12:14,200 So you can kind of float it. 213 00:12:14,200 --> 00:12:19,360 I held my breath, I don't know, for what felt like 30 seconds trying to push open that door, 214 00:12:19,360 --> 00:12:24,920 using my legs, bracing up inside the cabin. 215 00:12:24,920 --> 00:12:28,240 Well, you died. 216 00:12:28,240 --> 00:12:31,240 Yeah, I died. 217 00:12:31,240 --> 00:12:34,880 Jamie's passive observer view was a little eerie. 218 00:12:34,880 --> 00:12:38,040 I just sitting there watching the guy drown. 219 00:12:38,040 --> 00:12:41,040 He's like just going nuts on that door. 220 00:12:41,040 --> 00:12:47,120 He's really using up his oxygen and it didn't take him that long to run out. 221 00:12:47,120 --> 00:12:49,560 You don't want to be in a car when it goes down like that. 222 00:12:49,560 --> 00:12:51,480 It's scary. 223 00:12:51,480 --> 00:12:56,400 The bottom line is Adam ran out of air before he could open the door. 224 00:12:56,400 --> 00:12:57,640 That myth is confirmed. 225 00:12:57,640 --> 00:13:04,200 I could not open that door until the cab seemed to be full of water for a while. 226 00:13:04,200 --> 00:13:08,040 Yeah, you were given it all you could and you just weren't able to do anything with 227 00:13:08,040 --> 00:13:11,400 that door until we started to level out. 228 00:13:11,400 --> 00:13:13,440 That's the point that you opened the door. 229 00:13:13,440 --> 00:13:15,720 And that was quite a while. 230 00:13:15,720 --> 00:13:19,960 Differential pressure could be such a downer. 231 00:13:19,960 --> 00:13:22,960 I got to tell you, I've been wanting to do this since we've been doing this show and 232 00:13:22,960 --> 00:13:25,240 that was still pretty terrifying. 233 00:13:25,320 --> 00:13:30,560 Yeah, sitting there in the back seat watching you drown was kind of unsettling somehow. 234 00:13:30,560 --> 00:13:34,960 If you'd like to watch the entire sequence of me sinking in the car uncut, you can log 235 00:13:34,960 --> 00:13:37,880 on to Discovery.com slash MythBusters. 236 00:13:37,880 --> 00:13:41,120 And see it in real time. 237 00:13:41,120 --> 00:13:45,240 But now let's cut to a new myth. 238 00:13:45,240 --> 00:13:50,840 Alright, this myth has been around forever. 239 00:13:50,840 --> 00:13:52,640 Okay, what is it? 240 00:13:52,640 --> 00:13:56,200 You can't fold a piece of paper in half more than seven times. 241 00:13:56,200 --> 00:13:57,200 I don't believe it. 242 00:13:57,200 --> 00:13:58,200 Let's do it. 243 00:13:58,200 --> 00:13:59,200 That's why I brought a piece of paper. 244 00:13:59,200 --> 00:14:00,200 Alright, let's see. 245 00:14:00,200 --> 00:14:01,200 Show us. 246 00:14:01,200 --> 00:14:04,440 Alright, that's one. 247 00:14:04,440 --> 00:14:08,520 This myth is a MythBusters fan site's special request. 248 00:14:08,520 --> 00:14:13,960 It's a theory that most people first hear in elementary school and Carrie is finding out 249 00:14:13,960 --> 00:14:15,760 it isn't child's play. 250 00:14:15,760 --> 00:14:19,280 Don't break the table. 251 00:14:19,280 --> 00:14:20,280 There's seven. 252 00:14:20,280 --> 00:14:22,120 Come on, Carrie, one more. 253 00:14:22,120 --> 00:14:23,120 One more, you can do it. 254 00:14:23,120 --> 00:14:24,120 Come on, pump it. 255 00:14:24,120 --> 00:14:25,120 I'm not giving up yet. 256 00:14:25,120 --> 00:14:26,120 Yeah. 257 00:14:26,120 --> 00:14:31,960 Eight doesn't, I don't think eight worked. 258 00:14:31,960 --> 00:14:33,960 I think that's seven. 259 00:14:33,960 --> 00:14:38,040 You know what, there's got to be a way to fold this piece of paper more than seven times. 260 00:14:38,040 --> 00:14:42,880 Okay, well let's break this down and figure out what it takes to fold it eight times 261 00:14:42,880 --> 00:14:43,880 more. 262 00:14:43,880 --> 00:14:47,120 I have a feeling you're going to get math involved again. 263 00:14:47,120 --> 00:14:48,120 Correct, Carrie. 264 00:14:48,120 --> 00:14:50,720 It's called exponential growth. 265 00:14:50,720 --> 00:14:56,160 Every time you fold a piece of paper in half, it gets twice as small and twice as thick. 266 00:14:56,160 --> 00:15:02,560 A piece of paper folded just seven times quickly multiplies to 128 layers. 267 00:15:02,560 --> 00:15:06,280 Eight folds doubles again to 256 layers. 268 00:15:06,280 --> 00:15:09,640 And the theory is this is too thick to bend. 269 00:15:09,640 --> 00:15:15,240 Okay, so the challenge is each of us has two hours to take these pieces of paper and see 270 00:15:15,240 --> 00:15:16,680 how many times we can fold them. 271 00:15:16,680 --> 00:15:19,880 The person that folds them the most wins. 272 00:15:19,880 --> 00:15:25,120 Using standard letter eight and a half by 11 office paper, our first contender, Tori 273 00:15:25,120 --> 00:15:26,840 Balechi, steps up. 274 00:15:26,840 --> 00:15:29,040 First you must massage the paper. 275 00:15:29,040 --> 00:15:35,320 If you get it relaxed so that it'll fold easier. 276 00:15:35,320 --> 00:15:39,000 It's one. 277 00:15:39,000 --> 00:15:45,280 Tori's basic method of folding and rotating is smooth all the way until he gets to number 278 00:15:45,280 --> 00:15:46,280 seven. 279 00:15:46,800 --> 00:15:50,400 This is tricky here. 280 00:15:50,400 --> 00:15:54,560 Is he about to wrench this myth open already? 281 00:15:54,560 --> 00:15:59,480 The pressure is on to bring it home to eight. 282 00:15:59,480 --> 00:16:02,000 Eight. 283 00:16:02,000 --> 00:16:03,000 Got it. 284 00:16:03,000 --> 00:16:08,160 I think you managed to wad it in half eight times, but look, that's not half. 285 00:16:08,160 --> 00:16:09,160 There's one. 286 00:16:09,160 --> 00:16:10,760 That's not a fault. 287 00:16:10,760 --> 00:16:12,520 Oh, and you cut the paper. 288 00:16:12,520 --> 00:16:14,520 You cut the paper. 289 00:16:14,520 --> 00:16:17,600 Tori's tactic is to focus on the fold. 290 00:16:17,600 --> 00:16:25,000 My way of tackling this seven-paper fold problem is to hopefully use a little bit of compression, 291 00:16:25,000 --> 00:16:30,240 a little bit of steam, and a little bit of sanding to make that last fold, which seems 292 00:16:30,240 --> 00:16:33,240 to be the problem a little bit easier. 293 00:16:33,240 --> 00:16:37,880 A home-spun touch might be just what this myth needs. 294 00:16:37,880 --> 00:16:41,640 After ironing a perfect crease, she rubs it with fine sandpaper. 295 00:16:42,640 --> 00:16:44,640 It's just going to be a tiny bit thinner. 296 00:16:44,640 --> 00:16:49,120 I'm just thinking maybe just that microscopic little edge it could give me. 297 00:16:49,120 --> 00:16:52,480 Her idea may just iron out the kinks in this competition. 298 00:16:52,480 --> 00:16:53,480 Have you done with this? 299 00:16:53,480 --> 00:16:58,280 I was wondering if you could come over and iron my newspaper. 300 00:16:58,280 --> 00:17:02,840 But she too runs out of steam at seven. 301 00:17:02,840 --> 00:17:03,840 Seven times. 302 00:17:03,840 --> 00:17:04,840 That's it. 303 00:17:04,840 --> 00:17:08,120 This ends up being a spit-wad. 304 00:17:08,120 --> 00:17:12,080 Meanwhile, Grant has really been pondering this paper puzzle. 305 00:17:12,080 --> 00:17:16,600 Okay, so I think that this is actually a dimensional problem. 306 00:17:16,600 --> 00:17:22,480 And here, this is a piece of 20-pound 8.5 by 11, like, office paper. 307 00:17:22,480 --> 00:17:26,840 And it is 3,000ths of an inch. 308 00:17:26,840 --> 00:17:31,920 So if I make that thinner, theoretically, I should be able to get more folds in the 309 00:17:31,920 --> 00:17:33,400 same amount of space. 310 00:17:33,400 --> 00:17:35,840 And that's why I have this. 311 00:17:35,840 --> 00:17:39,120 This is tracing paper, technically still paper. 312 00:17:39,120 --> 00:17:42,320 Isn't it a little early in the game to start cheating? 313 00:17:42,320 --> 00:17:43,920 Still paper. 314 00:17:43,920 --> 00:17:46,640 A cheat, quite the contrary. 315 00:17:46,640 --> 00:17:48,880 Grant sees himself as a purist. 316 00:17:48,880 --> 00:17:56,560 No hammer, no plan, no sanding. 317 00:17:56,560 --> 00:18:03,400 Plus he has a cunning plan, to fold lengthwise repeatedly, then widthwise repeatedly. 318 00:18:03,400 --> 00:18:07,440 Now for the folding in half. 319 00:18:07,440 --> 00:18:12,160 If you fold a piece of paper in alternating directions, it doesn't constrain itself with 320 00:18:12,160 --> 00:18:13,160 each fold. 321 00:18:13,160 --> 00:18:16,800 So, it's easier to keep folding. 322 00:18:16,800 --> 00:18:18,960 There's number eight. 323 00:18:18,960 --> 00:18:20,160 Eight. 324 00:18:20,160 --> 00:18:24,680 But someone still doesn't want to concede defeat. 325 00:18:24,680 --> 00:18:25,680 Twenty-two. 326 00:18:25,680 --> 00:18:26,680 Twenty-three. 327 00:18:26,680 --> 00:18:36,120 Next, the team finally finish building their broadsheet. 328 00:18:36,120 --> 00:18:40,280 Oh, look at this ocean of paper. 329 00:18:40,280 --> 00:18:43,560 And Adam learns why you should never go sailing in a car. 330 00:18:43,560 --> 00:18:49,240 What is getting to the top of the window here? 331 00:18:49,240 --> 00:18:53,640 Grant, Tori and Carrie are trying to burn a hole in the seven paper fold myth. 332 00:18:53,640 --> 00:18:56,200 You got something you want to say, Grant? 333 00:18:56,880 --> 00:18:58,600 As a matter of fact, I do. 334 00:18:58,600 --> 00:19:04,840 I think it's clear that I won the competition with eight folds, and not only did I win, 335 00:19:04,840 --> 00:19:06,040 I busted the myth. 336 00:19:06,040 --> 00:19:07,360 You know what though? 337 00:19:07,360 --> 00:19:10,400 You got eight folds, but you changed the method of the folding. 338 00:19:10,400 --> 00:19:14,840 The obvious way would be to fold it in half, turn it 90 degrees and fold it again. 339 00:19:14,840 --> 00:19:17,880 Every time we tried to do that, we couldn't get more than seven folds. 340 00:19:17,880 --> 00:19:19,680 I mean, there might be some truth to this myth. 341 00:19:19,680 --> 00:19:24,440 Well, if we use a really big piece of paper, I think there's a possibility that we could 342 00:19:24,440 --> 00:19:25,960 get more than seven folds. 343 00:19:25,960 --> 00:19:30,960 OK, then let's get the biggest piece of seamless paper we can find and try it again. 344 00:19:30,960 --> 00:19:33,000 All right then. 345 00:19:33,000 --> 00:19:38,720 They roll out the biggest seamless piece of paper they could find, 12 and a half by 15 346 00:19:38,720 --> 00:19:39,720 feet. 347 00:19:39,720 --> 00:19:44,920 In theory, increasing the paper's dimensions should make it easier to reach the elusive 348 00:19:44,920 --> 00:19:45,920 eight-fold goal. 349 00:19:45,920 --> 00:19:47,920 You want to have big biceps? 350 00:19:47,920 --> 00:19:48,920 Do this. 351 00:19:48,920 --> 00:19:49,920 Do this exercise. 352 00:19:49,920 --> 00:20:00,040 For the first couple of folds, the paper is a pushover, but it's shrinking with surprising 353 00:20:00,040 --> 00:20:03,240 speed. 354 00:20:03,240 --> 00:20:05,080 Gets real small real fast. 355 00:20:05,080 --> 00:20:06,080 Sure does. 356 00:20:06,080 --> 00:20:07,080 So this is seven. 357 00:20:07,080 --> 00:20:09,080 We're supposed to get one more fold. 358 00:20:09,080 --> 00:20:11,080 I think maybe. 359 00:20:11,080 --> 00:20:15,080 Good luck. 360 00:20:15,080 --> 00:20:23,080 But no matter what sick methods of intimidation they try, the paper doesn't break. 361 00:20:23,080 --> 00:20:25,360 The team is all torn up. 362 00:20:25,360 --> 00:20:32,440 Even using a piece of paper the size of a room 288 times larger than the letter size paper, 363 00:20:32,440 --> 00:20:35,400 they couldn't crack the seven-fold ceiling. 364 00:20:35,400 --> 00:20:37,280 So now what? 365 00:20:37,280 --> 00:20:40,240 This is six times thicker than the tracing paper. 366 00:20:40,240 --> 00:20:43,600 If we can learn anything from this little exercise, it would be we need to go thinner 367 00:20:43,600 --> 00:20:45,240 and we need to go bigger. 368 00:20:45,240 --> 00:20:46,240 Bigger? 369 00:20:46,240 --> 00:20:47,680 You got it, Carrie. 370 00:20:47,680 --> 00:20:53,080 No one knows space like NASA, and they have plenty of it at an empty airship hangar they've 371 00:20:53,080 --> 00:20:56,480 given us clearance to use at Moffitt Field. 372 00:20:56,480 --> 00:21:03,160 At more than 200 feet high, 1,000 feet long, and 300 feet wide, our crew will really be 373 00:21:03,160 --> 00:21:06,960 able to explore the outer reaches of this myth. 374 00:21:06,960 --> 00:21:13,560 The plan is to get 17 individual rolls and lay them out side by side, covering 170 by 375 00:21:13,560 --> 00:21:14,560 220 feet. 376 00:21:14,560 --> 00:21:18,400 The team will join them together with double-sided tape. 377 00:21:18,400 --> 00:21:23,560 Then they'll use whatever methods necessary to try and fold it into a submission. 378 00:21:23,560 --> 00:21:26,080 Basically, you're going to have to fill this whole area. 379 00:21:26,080 --> 00:21:33,280 Yeah, well, we have 170 feet this way and 220 this way before we get to any equipment. 380 00:21:33,280 --> 00:21:34,640 So will that work out for us? 381 00:21:34,640 --> 00:21:37,120 Yeah, it's perfect to scale up an 8.5 by 11 sheet. 382 00:21:37,120 --> 00:21:39,680 So this is going to be a long day. 383 00:21:39,680 --> 00:21:41,600 We have a lot of work. 384 00:21:41,600 --> 00:21:43,280 Then let's roll. 385 00:21:43,280 --> 00:21:46,720 They position the first roll, give it a push, and they're off. 386 00:21:46,720 --> 00:21:50,760 This is going to be the biggest piece of paper ever. 387 00:21:50,760 --> 00:21:53,720 One down. 388 00:21:53,720 --> 00:21:57,440 16 more to go. 389 00:21:57,440 --> 00:22:02,880 Their first 220 feet of scroll has been successfully unrolled. 390 00:22:02,880 --> 00:22:08,640 To secure roll number two, they need double-sided tape. 391 00:22:08,640 --> 00:22:14,160 Each inch by inch, they press the sticky stuff along the edge of the paper. 392 00:22:14,160 --> 00:22:18,560 Time to truck in roll number two. 393 00:22:18,560 --> 00:22:20,040 Roll down, tape down. 394 00:22:20,040 --> 00:22:22,360 I think we get the concept. 395 00:22:22,360 --> 00:22:26,640 Later, will the team's paper-fold attempt be all torn up? 396 00:22:26,640 --> 00:22:30,320 Uh-oh, we got a situation. 397 00:22:30,320 --> 00:22:34,240 Coming up, we test every survival technique for escaping from a car that you've driven 398 00:22:34,240 --> 00:22:36,240 off a bridge. 399 00:22:37,240 --> 00:22:43,360 Back at the pool, Jamie and Adam are testing ways to escape a car that's plunged into the 400 00:22:43,360 --> 00:22:44,360 drain. 401 00:22:44,360 --> 00:22:48,840 They've already discovered that if you wait for the cabin to fill with water so the differential 402 00:22:48,840 --> 00:22:54,280 pressure equalizes and releases its grip on the doors, it could be too late. 403 00:22:54,280 --> 00:22:58,200 Now, they're going to try out a modified survival technique. 404 00:22:58,200 --> 00:23:01,440 Oh, here we are, day two. 405 00:23:01,440 --> 00:23:06,560 The first maneuver on their cheating death checklist is to try and open the door before 406 00:23:06,560 --> 00:23:08,640 the car starts to sink. 407 00:23:08,640 --> 00:23:13,200 I figure for this particular technique to work, you need to do it right the minute you 408 00:23:13,200 --> 00:23:14,200 hit the water. 409 00:23:14,200 --> 00:23:17,440 If you hesitate, it's all over and you've got to ride it out. 410 00:23:17,440 --> 00:23:19,440 Here we go. 411 00:23:19,440 --> 00:23:27,280 Adam's plan of action is, I'm just going to wait until the water gets into my ankles 412 00:23:27,280 --> 00:23:29,160 and then I'm going to try and open the door. 413 00:23:29,880 --> 00:23:30,880 Here we go. 414 00:23:30,880 --> 00:23:31,880 Oh man. 415 00:23:31,880 --> 00:23:34,680 Oh, that sound is so long. 416 00:23:34,680 --> 00:23:35,680 The water rushes in. 417 00:23:35,680 --> 00:23:42,880 Okay, I'm starting to see it on the floor and it's coming up to my ankles. 418 00:23:42,880 --> 00:23:44,680 Now I'm going to try and open the door. 419 00:23:44,680 --> 00:23:46,680 And Adam rushes out. 420 00:23:51,680 --> 00:23:55,760 The surface exit via the door, totally viable. 421 00:23:55,760 --> 00:24:00,120 I waited until the water was up to the top of my shoes and I was still able to push this 422 00:24:00,120 --> 00:24:01,600 door open. 423 00:24:01,600 --> 00:24:03,960 The water rises slowly upwards. 424 00:24:03,960 --> 00:24:07,120 Next, he's going to wait until it gets to his waist. 425 00:24:07,120 --> 00:24:10,320 Okay, past my shoes, halfway up my shins. 426 00:24:10,320 --> 00:24:13,720 All right, now I'm looking at, my God, it set my knees. 427 00:24:13,720 --> 00:24:15,200 I'm not going to be able to open the door. 428 00:24:15,200 --> 00:24:16,200 All right, wait. 429 00:24:16,200 --> 00:24:18,200 This one's no push over. 430 00:24:18,200 --> 00:24:21,960 As the water level climbs, so does the amount of pressure. 431 00:24:21,960 --> 00:24:26,160 Adam has to brace himself against the opposite door to force it open. 432 00:24:33,560 --> 00:24:35,000 I was able to do it. 433 00:24:35,000 --> 00:24:36,760 But only just. 434 00:24:36,760 --> 00:24:39,040 This time he's going even higher. 435 00:24:39,040 --> 00:24:42,040 I'm going to wait until I see water hit the top of this window. 436 00:24:42,040 --> 00:24:46,640 Then I'm going to use all my strength against the opposite door to try and push it open. 437 00:24:48,640 --> 00:24:51,440 Dude, I'm going to have dreams about this tonight. 438 00:24:51,440 --> 00:24:54,440 All right, water's getting to the top of the window here. 439 00:24:54,440 --> 00:24:56,440 All right, here we go. 440 00:24:56,440 --> 00:24:59,440 It's almost at the top, almost there. 441 00:24:59,440 --> 00:25:01,440 Three, two, one, go. 442 00:25:01,440 --> 00:25:06,160 The differential pressure on the other side of the door has become too strong and holds 443 00:25:06,160 --> 00:25:08,160 it shut. 444 00:25:08,160 --> 00:25:13,160 Adam gamely pushes back, but he's like a krill fighting a whale. 445 00:25:13,160 --> 00:25:17,160 It's not long before it's RIP for our little crustacean. 446 00:25:22,160 --> 00:25:25,160 I think we found the cutoff point. 447 00:25:25,160 --> 00:25:30,160 Actually, the car near the door after it hits the water is a viable option. 448 00:25:30,160 --> 00:25:35,160 If you have a very small window, by the time you can see water halfway up the window, it's 449 00:25:35,160 --> 00:25:37,160 pretty much too late. 450 00:25:39,160 --> 00:25:45,320 The art of paper folding, known as origami, is believed to have originated as long ago 451 00:25:45,320 --> 00:25:48,360 as the first century AD in China. 452 00:25:48,360 --> 00:25:53,360 Masters of the craft believe it is a pursuit in which you can unlock the secrets of creation. 453 00:25:53,360 --> 00:25:56,360 It looks like a big giant diaper. 454 00:25:56,360 --> 00:26:02,360 That might be a stretch for our novices here today, but finally they reach the last joint. 455 00:26:02,360 --> 00:26:06,360 Ooh, look at this ocean of paper. 456 00:26:10,360 --> 00:26:14,360 I think this is going to be probably the biggest attempt to fold a piece of paper more than 457 00:26:14,360 --> 00:26:15,360 seven times. 458 00:26:15,360 --> 00:26:20,360 Actually, in 2002, there's this high school student named Brittany Gallivan, and for an 459 00:26:20,360 --> 00:26:24,360 extra credit project, she did the seven-paper fold and got more than seven folds. 460 00:26:24,360 --> 00:26:25,360 What? 461 00:26:25,360 --> 00:26:26,360 How? 462 00:26:26,360 --> 00:26:31,360 She used toilet paper and folded it lengthwise, but the toilet paper was 4,000 feet long. 463 00:26:31,360 --> 00:26:33,360 How many folds did she get? 464 00:26:33,360 --> 00:26:34,360 She got 12 folds. 465 00:26:34,360 --> 00:26:38,360 She had to use a shopping mall, and it took over seven hours to fold. 466 00:26:38,360 --> 00:26:40,360 Wow, that's impressive. 467 00:26:40,360 --> 00:26:44,360 She may have beaten the seven-paper fold, but she did it lengthwise. 468 00:26:44,360 --> 00:26:49,360 I still think the spirit of the myth is folding it in half, turning it 90, and folding it again. 469 00:26:49,360 --> 00:26:54,360 That's true, and within the parameters of the spirit of the myth, that record is still up for grabs. 470 00:26:54,360 --> 00:26:55,360 I say we do it. 471 00:26:55,360 --> 00:26:57,360 We just got to be careful we don't get any paper cuts. 472 00:26:57,360 --> 00:27:02,360 With the paper-built finish, they can finally begin folding. 473 00:27:02,360 --> 00:27:07,360 It socks only as the whole Mythbusters crew grabs an edge. 474 00:27:07,360 --> 00:27:12,360 My new worry is that this paper is going to rip when we start trying to fold it. 475 00:27:12,360 --> 00:27:17,360 I mean, it's really thin, and the size of these pieces of paper is so heavy. 476 00:27:17,360 --> 00:27:21,360 I just see ripping for days. 477 00:27:21,360 --> 00:27:25,360 One rip and their best laid plans will be shredded. 478 00:27:25,360 --> 00:27:27,360 Uh-oh, uh-oh, we got a situation. 479 00:27:27,360 --> 00:27:33,360 Coming up on Mythbusters, can we fold this piece of paper more than seven times? 480 00:27:33,360 --> 00:27:38,360 And soon, Adam takes the art of heavy breathing to a whole new level. 481 00:27:42,360 --> 00:27:49,360 If you drive your car into the drink, you can't get out alive unless you open a door at precisely the right moment. 482 00:27:49,360 --> 00:27:52,360 So is there another window of opportunity? 483 00:27:52,360 --> 00:27:58,360 So we know it's pretty much impossible to open the door once the car is submerged in underwater. 484 00:27:58,360 --> 00:28:02,360 The question everyone asks after that is, well, why didn't you open the window? 485 00:28:02,360 --> 00:28:05,360 That's what I'm going to do, a shop test to find out. 486 00:28:05,360 --> 00:28:09,360 I have one electrically powered window, and I have one manual powered window. 487 00:28:09,360 --> 00:28:13,360 I'm going to put them under the same kind of strain that they'd experience underwater and try to open them. 488 00:28:13,360 --> 00:28:21,360 The 350 pounds Adam is adding is equivalent to the pressure the window would be under at a depth of just two feet. 489 00:28:21,360 --> 00:28:30,360 I do not know of a more visual way to make clear how much pressure you're dealing with when you put things underwater. 490 00:28:30,360 --> 00:28:33,360 Then he tries to crank it open. 491 00:28:33,360 --> 00:28:38,360 I should point out I'm in a really good position for leverage to open this window. 492 00:28:38,360 --> 00:28:41,360 But there's not even a sliver of a crack. 493 00:28:41,360 --> 00:28:47,360 There it goes. It just failed. Yeah, the gear just slipped. 494 00:28:47,360 --> 00:28:57,360 Under that kind of pressure, there's so much force pushing the glass against the frame of the car that the manual lever is going to break. 495 00:28:57,360 --> 00:29:03,360 Maybe electric windows have more power, but the common perception is they don't even work underwater. 496 00:29:03,360 --> 00:29:11,360 This is the electric door, and the first thing I want to do is dump the electric door in this container with the battery and see how long the electric hold out for. 497 00:29:11,360 --> 00:29:13,360 Okay, here we go. 498 00:29:13,360 --> 00:29:16,360 The battery's on the bottom. 499 00:29:16,360 --> 00:29:18,360 They let it steep. 500 00:29:21,360 --> 00:29:26,360 After 45 minutes, surprisingly, it's still going strong. 501 00:29:26,360 --> 00:29:31,360 So it's not out of the question that power windows could still work underwater. 502 00:29:31,360 --> 00:29:35,360 But what about the effect of differential pressure? 503 00:29:35,360 --> 00:29:38,360 Ready?
