1 00:00:00,000 --> 00:00:06,000 The stuff we do is dangerous. Don't try this at home. Where would you call experts? 2 00:00:07,800 --> 00:00:10,040 On this episode of MythBusters, 3 00:00:11,200 --> 00:00:13,600 Adam and Jamie go full throttle. 4 00:00:14,520 --> 00:00:18,080 For the most dangerous stunt in MythBusters history. 5 00:00:18,480 --> 00:00:26,080 Did such an aggressive wheelie his head fell off. Testing the viral video that a motorcycle could surf the surface of a lake. 6 00:00:26,080 --> 00:00:28,080 I want to try it. 7 00:00:28,720 --> 00:00:36,480 But will it be man over bike? Could he plant himself right here and just start flying? Or will Jamie torque on water? 8 00:00:38,440 --> 00:00:43,560 Meanwhile, Carri Torian Grant get the drop on a free fall free for all. 9 00:00:44,400 --> 00:00:46,680 I don't even want to know what the G's are on that. 10 00:00:46,840 --> 00:00:54,120 Finding out if a criminal could make a parachute out of the paraphernalia inside a hotel room. Is that the new fall fashion? 11 00:00:54,880 --> 00:00:56,880 But will there crazy canopies? 12 00:00:58,080 --> 00:01:00,680 A lot of wet floors with all these shower curtains missing. 13 00:01:00,680 --> 00:01:03,680 Let Buster skydive and survive. 14 00:01:04,280 --> 00:01:05,080 Come on. 15 00:01:05,680 --> 00:01:06,440 Open. 16 00:01:11,080 --> 00:01:13,080 Who are the MythBusters? 17 00:01:14,000 --> 00:01:17,200 Adam Savage. This is science in action. 18 00:01:17,200 --> 00:01:18,400 And Jamie Heineman. 19 00:01:19,000 --> 00:01:19,680 Bye-bye. 20 00:01:20,400 --> 00:01:26,600 Between them more than 30 years of special effects experience. Together with Brad Dimahara. 21 00:01:26,600 --> 00:01:28,200 That is crazy. 22 00:01:28,200 --> 00:01:29,200 Carri Byron. 23 00:01:30,400 --> 00:01:32,000 And Tori Balachian. 24 00:01:32,000 --> 00:01:34,000 It's about to get real. 25 00:01:34,000 --> 00:01:36,000 They don't just tell the myths. 26 00:01:37,000 --> 00:01:39,000 They put them to the test. 27 00:01:50,800 --> 00:01:54,800 Jamie, you remember when Carri Grant and Tori did the episode about a sports car skipping across a lake? 28 00:01:54,800 --> 00:01:55,600 I do. 29 00:01:55,800 --> 00:01:57,800 Fifty miles an hour. 30 00:02:01,400 --> 00:02:03,400 That car didn't skip. It flipped. 31 00:02:03,800 --> 00:02:09,600 We got one similar to that this time except this time it's a motorcycle riding on the water. 32 00:02:10,000 --> 00:02:12,800 A motorcycle actually riding on top of water. 33 00:02:12,800 --> 00:02:16,600 Apparently we got a motorcycleist. He's riding down the freeway way too fast. 34 00:02:16,600 --> 00:02:19,800 He comes to a bend and when he comes to the bend he can't make it. 35 00:02:20,000 --> 00:02:26,000 So he plows right through it and there is a lake except that he stays on top of the lake and makes it safely to the other side. 36 00:02:26,000 --> 00:02:29,000 It's dangerous and fun. I'm in. 37 00:02:29,000 --> 00:02:30,000 Excellent. 38 00:02:33,000 --> 00:02:37,000 Motorbikes and water seem like a catastrophic combination. 39 00:02:39,000 --> 00:02:47,000 Yet according to this myth, if you take the lake at freeway speeds you could burn aqua all the way to the other side. 40 00:02:47,200 --> 00:02:51,200 But will this physics defying feat prove more sink than skim? 41 00:02:52,200 --> 00:02:55,200 Clearly this episode ends with one of us. 42 00:02:55,200 --> 00:03:01,200 I'm guessing it's you riding a big powerful motorcycle and attempting to keep it on top of the water. 43 00:03:01,200 --> 00:03:08,200 Yeah, but I don't think we should just jump right into this because it involves high speed crashes, drowning, broken bones. 44 00:03:08,200 --> 00:03:09,200 It's risky. 45 00:03:09,200 --> 00:03:12,200 All right. Well, they do make some very powerful RC motorcycles. 46 00:03:12,400 --> 00:03:17,400 What say we take one of those out into the field, ride them over a small body of water and see what we can learn on the high speed camera? 47 00:03:17,400 --> 00:03:18,400 Sure. Why not? 48 00:03:23,400 --> 00:03:27,400 And we're not going to be going stampeding towards full scale right away in this story. 49 00:03:27,400 --> 00:03:37,400 We've come to a basically off road motorcycle park not far from the Mythbusters shop and we're going to be doing a little bit of experimenting with these. 50 00:03:37,400 --> 00:03:41,400 These are little radio controlled motorcycles and they happen to have a gyro-tron. 51 00:03:42,400 --> 00:03:45,400 They're going to have a gyroscope in the rear wheel to help them stabilize as they go. 52 00:03:45,400 --> 00:03:48,400 The top speed on them is about 20 miles an hour. 53 00:03:48,400 --> 00:03:50,400 What that'll do in water? 54 00:03:50,400 --> 00:03:53,400 I have no idea, but that's what we're here to find out. 55 00:03:56,400 --> 00:04:00,400 Well, our scale bikes require a scaled pool and that's just what this is. 56 00:04:00,400 --> 00:04:11,400 With a nice gentle transition over there, it's only a couple of inches deep and with the aid of our high speed camera, hopefully it will illuminate some key things we need to know about whether or not bikes can stay on top of the road. 57 00:04:12,400 --> 00:04:17,400 Add with the H2O ready to go, it's time for the wheels to meet the water. 58 00:04:17,400 --> 00:04:18,400 Here we go. 59 00:04:18,400 --> 00:04:19,400 Oh! 60 00:04:25,400 --> 00:04:26,400 Nice! 61 00:04:29,400 --> 00:04:31,400 Mr. Heidemann delivers. 62 00:04:31,400 --> 00:04:34,400 No riding a bike through water, he wheelies through water. 63 00:04:35,400 --> 00:04:41,400 It's not quite the wheel deal as this myth is about skimming on two wheels, not one. 64 00:04:41,600 --> 00:04:44,600 But luckily they don't have long to wait. 65 00:04:44,600 --> 00:04:45,600 Yeah, this is it! 66 00:04:46,600 --> 00:04:47,600 Woo! 67 00:04:47,600 --> 00:04:50,600 As the Heidemann masters the two wheel maneuver. 68 00:04:50,600 --> 00:04:51,600 Yeah! 69 00:04:51,600 --> 00:04:52,600 Woo! 70 00:04:53,600 --> 00:05:03,600 And for triumphant trips later, it's time to see if the bike's riding the top of the pond or the bottom, thanks to the high speed review. 71 00:05:03,600 --> 00:05:06,600 But let's see what we can learn. 72 00:05:07,600 --> 00:05:12,600 Wow, it's sort of on the surface right in the beginning because it's coming off of that initial ramp. 73 00:05:12,600 --> 00:05:14,600 The rear wheel is down though. 74 00:05:14,600 --> 00:05:16,600 And it's going down further. 75 00:05:16,600 --> 00:05:20,600 At this point, it's clear that both wheels are down. 76 00:05:20,600 --> 00:05:22,600 It is definitely deep in the water. 77 00:05:22,600 --> 00:05:27,600 It's almost deep enough where I could say it really feels like it's riding on the bottom. 78 00:05:27,600 --> 00:05:29,600 It's not the news they were looking for. 79 00:05:29,600 --> 00:05:35,600 On each and every run, their bike is driving through the water and not over it. 80 00:05:36,600 --> 00:05:42,600 And that means for this myth to stay afloat, Adam and Janie are going to need a plan B. 81 00:05:46,600 --> 00:05:50,600 Next, Carri-Torre and Grant shoot the breeze. 82 00:05:52,600 --> 00:05:58,600 Alright, so this next one sounds like a Hollywood action movie, but apparently it's totally legit. 83 00:05:58,600 --> 00:05:59,600 Alright, let's hear it. 84 00:05:59,600 --> 00:06:04,600 Alright, so wanted criminal, surrounded by police, tracked down to the 20th floor of a hotel. 85 00:06:04,600 --> 00:06:08,600 After a protracted negotiation, they break down the door and guess what they find? 86 00:06:08,600 --> 00:06:10,600 Money, jewels. 87 00:06:10,600 --> 00:06:13,600 Yes, but also a homemade parachute. 88 00:06:13,600 --> 00:06:14,600 That one sounds familiar. 89 00:06:14,600 --> 00:06:19,600 The guy was stuck in his hotel room for three hours and he started making a homemade parachute out of sheets and shower curtains. 90 00:06:19,600 --> 00:06:23,600 But he never made the jump because the police broke in and caught him before he could. 91 00:06:23,600 --> 00:06:24,600 So he never jumped. 92 00:06:24,600 --> 00:06:26,600 We don't know if the parachute actually works. 93 00:06:26,600 --> 00:06:27,600 Exactly. 94 00:06:27,600 --> 00:06:30,600 Can you make a homemade parachute out of things you can find in a standard hotel room?

99 00:06:44,600 --> 00:06:49,600 Is there any way an improvised parachute could let you down safely? 100 00:06:50,600 --> 00:06:51,600 Alright guys, how about this? 101 00:06:51,600 --> 00:06:56,600 We get all of the standard contents from a hotel room, you know, drapes, sheets, shower curtains, lamp cords, 102 00:06:56,600 --> 00:06:59,600 and we have three hours to build a parachute. 103 00:06:59,600 --> 00:07:00,600 Well, it's great. 104 00:07:00,600 --> 00:07:04,600 We can connect each of our shoots to Buster and drum from 20 stories just like in the myth. 105 00:07:04,600 --> 00:07:05,600 Alright, well we better get cracking. 106 00:07:05,600 --> 00:07:07,600 The police are on their way. 107 00:07:09,600 --> 00:07:10,600 Where's he going? 108 00:07:10,600 --> 00:07:13,600 Yep, first it's a build off or shoot out. 109 00:07:13,600 --> 00:07:18,600 We're working on the myth that you can make a parachute out of common things you might find in a hotel room. 110 00:07:18,600 --> 00:07:20,600 Now, that gives us so much material. 111 00:07:20,600 --> 00:07:24,600 We've got the bedding on the beds, the curtains, the blackout curtains, the rods, the strings, 112 00:07:24,600 --> 00:07:28,600 any cords you could find from lamps or TVs or ethernet cables, 113 00:07:28,600 --> 00:07:30,600 and the wealth that is the bathroom. 114 00:07:30,600 --> 00:07:33,600 And we have shower curtains, towels, anything you can think of. 115 00:07:33,600 --> 00:07:37,600 Now, we have three hours to do this because the burglar only had three hours 116 00:07:37,600 --> 00:07:41,600 to see which of us could come up with the most successful parachute. 117 00:07:41,600 --> 00:07:43,600 And the clock starts now. 118 00:07:43,600 --> 00:07:47,600 So the first decision is to choose their weaving of choice. 119 00:07:47,600 --> 00:07:50,600 So what I'm going to use is this blackout curtain. 120 00:07:50,600 --> 00:07:52,600 It's fabric coated by plastic. 121 00:07:52,600 --> 00:07:54,600 That's going to give me a lot of wind resistance. 122 00:07:54,600 --> 00:07:58,600 And not only that, that plastic coating is going to give me more strength. 123 00:07:58,600 --> 00:07:59,600 Hopefully this will work. 124 00:07:59,600 --> 00:08:03,600 I'm starting out with the lightest, least porous materials that I could find, 125 00:08:03,600 --> 00:08:06,600 which are the shower curtains, the liners. 126 00:08:06,600 --> 00:08:09,600 I'm going to attach them and make them the base of my parachute. 127 00:08:09,600 --> 00:08:11,600 I figure they'll hold the air the best. 128 00:08:11,600 --> 00:08:14,600 So what I'm doing is using these curtain rods to make a frame. 129 00:08:14,600 --> 00:08:18,600 And then from that, I'm going to drape this duvet cover over it. 130 00:08:18,600 --> 00:08:21,600 The reason I chose a duvet cover as opposed to regular sheets 131 00:08:21,600 --> 00:08:23,600 is I didn't want to sew any seams. 132 00:08:23,600 --> 00:08:27,600 I think if I have any seams in there, it's going to be not as strong. 133 00:08:27,600 --> 00:08:30,600 Indeed, because strength is vital, 134 00:08:30,600 --> 00:08:33,600 considering what their improvised shoots have to mimic. 135 00:08:33,600 --> 00:08:37,600 Now, the way a parachute works is by increasing the surface area of a falling object. 136 00:08:37,600 --> 00:08:39,600 So that way it has more contact with air. 137 00:08:39,600 --> 00:08:43,600 And it's this air resistance that accelerates the terminal velocity of a human 138 00:08:43,600 --> 00:08:47,600 from 120 miles an hour to less than five miles per hour for a soft landing. 139 00:08:47,600 --> 00:08:49,600 So that's what we're trying to match. 140 00:08:49,600 --> 00:08:54,600 Yep, it's a head-to-head challenge that's going to require some clever crafting. 141 00:08:54,600 --> 00:08:58,600 Whoa, what hotel are you staying in, the Ritz? 142 00:08:58,600 --> 00:09:02,600 I don't know, this looks more like the kind of hotel where you could rent the hot tub by the hour. 143 00:09:02,600 --> 00:09:06,600 And each myth buster is opting for a different shape of canopy. 144 00:09:06,600 --> 00:09:10,600 It's quite a challenge, especially with shower curtains and sheets. 145 00:09:10,600 --> 00:09:14,600 Grant's going for 144 square feet of fabric. 146 00:09:14,600 --> 00:09:18,600 I already ripped it. It's not a good thing. 147 00:09:18,600 --> 00:09:22,600 While Carrie is sewing sheets into a more traditional dome design. 148 00:09:22,600 --> 00:09:24,600 I'm using the cord from the curtains to tie it together, 149 00:09:24,600 --> 00:09:29,600 and then I'm leaving a hole right in the middle so that it should sail down straight. 150 00:09:29,600 --> 00:09:33,600 If that doesn't work, I'm going to tie a pillow to my head like a helmet. 151 00:09:33,600 --> 00:09:36,600 And Tori is patching together a rectangular shoot. 152 00:09:36,600 --> 00:09:41,600 So we're already one hour into this challenge, and I'm looking at the size of my parachute. 153 00:09:41,600 --> 00:09:45,600 I don't think this is going to be good enough. I don't think I'm going to get this done. 154 00:09:45,600 --> 00:09:47,600 It's my harness. 155 00:09:47,600 --> 00:09:49,600 What is that, the new fall fashion? 156 00:09:49,600 --> 00:09:53,600 Okay, time pressure is starting to get to me because I just don't think I can get this done. 157 00:09:53,600 --> 00:09:55,600 I don't think I can get this done in three hours. 158 00:09:57,600 --> 00:10:02,600 With less than five minutes to go, the guys race to stitch up this challenge. 159 00:10:02,600 --> 00:10:07,600 So what I've done is I've ripped out all the electrical wiring in my hotel room. 160 00:10:07,600 --> 00:10:11,600 So I'm going to diverge you this once, and I'm going to use that as my stringers for my parachute. 161 00:10:11,600 --> 00:10:13,600 I am feeling pretty darn confident. 162 00:10:13,600 --> 00:10:16,600 And with some last minute adjustments. 163 00:10:16,600 --> 00:10:19,600 If this is knotting on the ground, what's it going to do in the air? 164 00:10:19,600 --> 00:10:23,600 Oh man, I got 60 seconds. 165 00:10:23,600 --> 00:10:28,600 The cutting, taping, sewing, and sweating comes to an end. 166 00:10:28,600 --> 00:10:29,600 And... 167 00:10:29,600 --> 00:10:30,600 Done! 168 00:10:30,600 --> 00:10:31,600 Done. 169 00:10:31,600 --> 00:10:32,600 Done. 170 00:10:32,600 --> 00:10:33,600 Done! 171 00:10:33,600 --> 00:10:38,600 Three hours, three mythbusters, and three hotel rooms full of fabric later. 172 00:10:38,600 --> 00:10:41,600 And they've got three parachutes ready for the drop zone. 173 00:10:41,600 --> 00:10:45,600 You might think it looks a little flimsy, but hey, it's only got to work once. 174 00:10:45,600 --> 00:10:47,600 Is this going to save Buster's life? I don't know. 175 00:10:47,600 --> 00:10:51,600 But if I had to jump off a building and I had a choice between no parachute and this parachute, 176 00:10:51,600 --> 00:10:53,600 I guarantee you I'll take this choice. 177 00:10:54,600 --> 00:10:57,600 Wow, Kerry. That's a nice looking parachute you made. 178 00:10:57,600 --> 00:10:59,600 It actually looks like parachute. 179 00:10:59,600 --> 00:11:03,600 It's an artistic rendition of a parachute. Let's see if it actually flies like one. 180 00:11:03,600 --> 00:11:05,600 Alright, you ready? Let's do it. 181 00:11:08,600 --> 00:11:09,600 Three! 182 00:11:09,600 --> 00:11:10,600 Later, Buster goes down. 183 00:11:10,600 --> 00:11:12,600 One, two, three! 184 00:11:13,600 --> 00:11:15,600 And the tension rams up. 185 00:11:15,600 --> 00:11:16,600 Let's launch the beast. 186 00:11:16,600 --> 00:11:17,600 Now or never. 187 00:11:17,600 --> 00:11:20,600 But can a motorcycle ever turn motorboat? 188 00:11:21,600 --> 00:11:25,600 It's a myth that's hell on two wheels. 189 00:11:25,600 --> 00:11:29,600 But could a motorbike ever turn motorboat? 190 00:11:29,600 --> 00:11:34,600 Well, so far, you can lead a bike to water, but you can't make it skim. 191 00:11:34,600 --> 00:11:36,600 However, all is not lost. 192 00:11:37,600 --> 00:11:39,600 I, for one, learned a lot from that test. 193 00:11:39,600 --> 00:11:43,600 Yeah, who knew that you could wheelie across water and your head would fall off? 194 00:11:43,600 --> 00:11:48,600 Look, I want to somehow see if a motorcycle wheel actually does a thing. 195 00:11:48,600 --> 00:11:53,600 I want to see if a motorcycle wheel at speed gains real buoyancy on the water's surface. 196 00:11:53,600 --> 00:11:58,600 But how are we going to get one of these going 60 or 70 miles an hour on water under controlled conditions? 197 00:11:58,600 --> 00:12:00,600 Well, riding on water says boat to me. 198 00:12:00,600 --> 00:12:03,600 So why don't we hang the wheel off the side of a boat? 199 00:12:03,600 --> 00:12:05,600 They make boats that go 70 or 80 miles an hour? 200 00:12:05,600 --> 00:12:06,600 You bet they do. 201 00:12:06,600 --> 00:12:13,600 Yep, with top speeds of over 90 miles per hour, power boats sure can pace across a pond. 202 00:12:13,600 --> 00:12:20,600 But before they feel the need for speed, first they need to rustle up the wheel in the water. 203 00:12:20,600 --> 00:12:21,600 What you got? 204 00:12:21,600 --> 00:12:24,600 Well, at its most basic, this is the boat. 205 00:12:24,600 --> 00:12:26,600 This is the motorcycle wheel and scale to that boat. 206 00:12:26,600 --> 00:12:33,600 Obviously, you can sit in the water like this, and when we get up to speed, if the wheel does get buoyancy, it would rise up. 207 00:12:33,600 --> 00:12:36,600 And then the question is, how much weight can it support? 208 00:12:36,600 --> 00:12:38,600 And that's where this comes in. 209 00:12:38,600 --> 00:12:42,600 We can put on barbell weights of various sizes. 210 00:12:42,600 --> 00:12:43,600 Okay. 211 00:12:43,600 --> 00:12:44,600 Until we determine how much weight. 212 00:12:44,600 --> 00:12:45,600 Sure. 213 00:12:45,600 --> 00:12:47,600 I think this is pretty straightforward. 214 00:12:47,600 --> 00:12:52,600 It may be straightforward for Adam, but for the rest of us, here's a graphic. 215 00:12:52,600 --> 00:12:55,600 The weight of a motorbike means that in water, it'll sink. 216 00:12:55,600 --> 00:13:00,600 But if its wheels were spinning at highway speeds, could that keep it afloat? 217 00:13:00,600 --> 00:13:05,600 To find out, the plan is to attach a motorbike wheel to a speedboat. 218 00:13:05,600 --> 00:13:10,600 Then as the boat accelerates, the wheel should spin up onto the surface. 219 00:13:10,600 --> 00:13:16,600 But will it stay above water as the weight of a rider is added to it? 220 00:13:16,600 --> 00:13:19,600 It's a dastardly design. 221 00:13:19,600 --> 00:13:24,600 But in the workshop, Adam's galloping through the build. 222 00:13:24,600 --> 00:13:28,600 I don't know, for some reason it reminds me of a horse rearing up. 223 00:13:28,600 --> 00:13:31,600 A horse made of steel. 224 00:13:31,600 --> 00:13:38,600 And before you can say chrome pony, his steel rim rig is ready to saddle up. 225 00:13:38,600 --> 00:13:42,600 And on a local lake, it's time to put it to the test. 226 00:13:42,600 --> 00:13:47,600 The open air, the sun, there's just nothing not to love about boating, honestly. 227 00:13:47,600 --> 00:13:49,600 Let's get this thing in the water. 228 00:13:49,600 --> 00:13:50,600 Okay. 229 00:13:50,600 --> 00:13:52,600 This year is our test platform. 230 00:13:52,600 --> 00:13:56,600 20 feet long with a 300 horsepower outboard engine and a tunnel hull design. 231 00:13:56,600 --> 00:14:02,600 She is built for racing, built for speed, and will go between 85 and 90 miles per hour. 232 00:14:02,600 --> 00:14:04,600 Perfect for our testing purposes. 233 00:14:04,600 --> 00:14:06,600 First up, we need to get our rig bolted to it. 234 00:14:06,600 --> 00:14:08,600 The plan here is simple. 235 00:14:08,600 --> 00:14:10,600 Bolt the wheel to the boat. 236 00:14:10,600 --> 00:14:12,600 I claim the scientific rig in the name of... 237 00:14:12,600 --> 00:14:14,600 ...with busters. 238 00:14:14,600 --> 00:14:17,600 Lower the boat into the water. 239 00:14:17,600 --> 00:14:18,600 Perfect. 240 00:14:18,600 --> 00:14:20,600 And then take it for a spin. 241 00:14:20,600 --> 00:14:22,600 Let's get this party started. 242 00:14:22,600 --> 00:14:24,600 All right. 243 00:14:24,600 --> 00:14:26,600 Are you ready? 244 00:14:26,600 --> 00:14:27,600 Ready. 245 00:14:27,600 --> 00:14:28,600 Go! 246 00:14:28,600 --> 00:14:32,600 But almost immediately, it's clear that there's a problem. 247 00:14:32,600 --> 00:14:37,600 The tail end is so heavy that the boat's not only taking on water... 248 00:14:37,600 --> 00:14:39,600 You're spilling water over the side there. 249 00:14:39,600 --> 00:14:42,600 ...its top speed has plummeted. 250 00:14:42,600 --> 00:14:48,600 Our problem is there's so much drag, the boat's not able to get up on a plane where it sits on top of the water. 251 00:14:48,600 --> 00:14:50,600 That's where the real speed happens. 252 00:14:50,600 --> 00:14:52,600 Jamie's going to crawl up to the bow. 253 00:14:52,600 --> 00:14:55,600 I'm going to rig the wheel up and we'll see if it works. 254 00:14:55,600 --> 00:14:58,600 So with Jamie clinging on as a counterbalance... 255 00:14:58,600 --> 00:15:02,600 I've actually done this before to hang on top of the car. 256 00:15:02,600 --> 00:15:04,600 It's the moment of truth. 257 00:15:04,600 --> 00:15:05,600 Okay. 258 00:15:05,600 --> 00:15:07,600 All right.

Come on! 260 00:15:11,600 --> 00:15:14,600 At first, it all hangs in the balance. 261 00:15:14,600 --> 00:15:18,600 But when Adam gives the wheel a eave, they finally pick up speed. 262 00:15:18,600 --> 00:15:20,600 There it goes. 263 00:15:22,600 --> 00:15:24,600 As the boat clocks 50... 264 00:15:24,600 --> 00:15:25,600 Yes! 265 00:15:25,600 --> 00:15:26,600 Yeah! 266 00:15:26,600 --> 00:15:28,600 ...then 60 miles per hour. 267 00:15:28,600 --> 00:15:29,600 Come on! 268 00:15:30,600 --> 00:15:36,600 It's clear that the wheel is riding the water, which is great for the myth. 269 00:15:36,600 --> 00:15:41,600 What's less great is that this crazy contraption is so dangerous... 270 00:15:41,600 --> 00:15:43,600 Yeah! 271 00:15:43,600 --> 00:15:44,600 Whoa, whoa, whoa! 272 00:15:44,600 --> 00:15:45,600 Come on up! 273 00:15:46,600 --> 00:15:47,600 That's scary! 274 00:15:48,600 --> 00:15:51,600 ...that the guys decide to quit while they're ahead. 275 00:15:51,600 --> 00:15:52,600 Oh! 276 00:15:57,600 --> 00:16:00,600 All right. I've got some good news and some bad news. 277 00:16:00,600 --> 00:16:02,600 I'm going to start with the bad. 278 00:16:02,600 --> 00:16:05,600 The bad news is that our rig didn't quite work as planned. 279 00:16:05,600 --> 00:16:09,600 We had really wanted to start to add weight and experiment with different speeds of the boat 280 00:16:09,600 --> 00:16:15,600 to come up with a graph of speed to weight ratio that would tell us exactly how fast we'd have to hit the water at 281 00:16:15,600 --> 00:16:18,600 for the motorcycle wheel to support its rider. 282 00:16:18,600 --> 00:16:20,600 And we didn't quite get that. 283 00:16:20,600 --> 00:16:22,600 The good news is that even though it took everything we had, 284 00:16:22,600 --> 00:16:26,600 we were able to get the boat up on a plane and the wheel skipping across the water, 285 00:16:26,600 --> 00:16:31,600 which means that there is something to this and it means we can proceed with some confidence to full scale 286 00:16:31,600 --> 00:16:33,600 that this might just work. 287 00:16:36,600 --> 00:16:42,600 Cornered by the cops, could you improvise a parachute, defeat the free fall and flee to freedom? 288 00:16:42,600 --> 00:16:46,600 To find out, Carrie, Tori and Grant have unraveled the record 289 00:16:46,600 --> 00:16:50,600 and now have three makeshift shoots to deploy. 290 00:16:50,600 --> 00:16:56,600 It's time to find out if any of our do-it-yourself hotel parachutes can decelerate Buster gently to the ground. 291 00:16:56,600 --> 00:17:01,600 We've come out to Treasure Island on a beautiful day with a crane that can lift him 20 stories into the air. 292 00:17:01,600 --> 00:17:07,600 We're going to drop him with each of our designs, but first, the control. No parachute. 293 00:17:07,600 --> 00:17:12,600 Now to find out exactly what Buster is going to be experiencing in this drop, we're going to attach an accelerometer. 294 00:17:12,600 --> 00:17:16,600 Now for him to survive this fall, he has to withstand less than 100 Gs. 295 00:17:16,600 --> 00:17:20,600 For him to survive the fall without injury, he has to withstand less than 10 Gs. 296 00:17:20,600 --> 00:17:22,600 Don't look so sad, buddy. 297 00:17:22,600 --> 00:17:28,600 Yep, once again, Buster will have to do what he does best and take the fall from 200 feet. 298 00:17:28,600 --> 00:17:32,600 Alright, here we go. Bye-bye, Buster. In three, two, one. 299 00:17:39,600 --> 00:17:42,600 God, I don't even want to know what the Gs are on that. 300 00:17:43,600 --> 00:17:45,600 Well, thanks to the accelerometer. 301 00:17:45,600 --> 00:17:47,600 Alright, see what we got. 302 00:17:47,600 --> 00:17:49,600 It's easy enough to find out. 303 00:17:49,600 --> 00:17:52,600 Wow, look at that. 500 Gs. 304 00:17:52,600 --> 00:17:57,600 And he hit the ground at 83 miles an hour. He definitely did not survive that. 305 00:17:57,600 --> 00:18:02,600 But we'll jumping from 20 stories with a homemade shoot be any better. 306 00:18:03,600 --> 00:18:11,600 Here's why we're hoping our parachutes will work. Gravity acts on all objects, no matter how much they weigh, causing them to fall at the same rate. 307 00:18:13,600 --> 00:18:19,600 The only reason why two objects won't fall at the same rate is because of air resistance. 308 00:18:19,600 --> 00:18:22,600 These two pieces of paper, in fact, do weigh the same amount. 309 00:18:22,600 --> 00:18:28,600 But this one has a lot more surface air. It has to push a lot more air molecules out of the way to fall down. 310 00:18:28,600 --> 00:18:35,600 And thus, in order for this myth to be confirmed, this is what our parachutes will have to do. 311 00:18:35,600 --> 00:18:36,600 You ready? 312 00:18:36,600 --> 00:18:37,600 I am ready. 313 00:18:37,600 --> 00:18:41,600 And first to attempt that is Tori's blackout curtain canopy. 314 00:18:41,600 --> 00:18:43,600 That's something you don't see every day. 315 00:18:44,600 --> 00:18:49,600 Blackout curtain parachute drop in three, two, one. 316 00:18:53,600 --> 00:18:54,600 Yeah! 317 00:18:56,600 --> 00:19:00,600 Amazingly, Tori's shoot deployed and slowed Buster down. 318 00:19:00,600 --> 00:19:04,600 But unfortunately, not enough to head off the impact. 319 00:19:04,600 --> 00:19:07,600 Oh, Buster lost his hand. 320 00:19:07,600 --> 00:19:10,600 That is a bad sign. 321 00:19:11,600 --> 00:19:14,600 So we just dropped the blackout curtain parachute. 322 00:19:14,600 --> 00:19:16,600 And there's some good news, but there's some really bad news. 323 00:19:16,600 --> 00:19:20,600 The good news is the parachute opened and it decelerated Buster's descent. 324 00:19:20,600 --> 00:19:25,600 However, the bad news, when he hit the ground, he hit it with 160 Gs. 325 00:19:26,600 --> 00:19:30,600 That's well over 100 Gs, therefore Buster is dead. 326 00:19:30,600 --> 00:19:33,600 That brings the curtain down on Tori. 327 00:19:33,600 --> 00:19:36,600 But Grant's frame up is still to go. 328 00:19:36,600 --> 00:19:41,600 We got a technical difficulty. 329 00:19:41,600 --> 00:19:42,600 Oh boy. 330 00:19:42,600 --> 00:19:44,600 Trouble in Myth Busterland. 331 00:19:44,600 --> 00:19:48,600 The wind has picked up and apparently Grant's rig does not like that. 332 00:19:49,600 --> 00:19:51,600 Had to be a windy day, didn't it? 333 00:19:51,600 --> 00:19:55,600 Yep, Grant and his frame are all bent out of shape. 334 00:19:55,600 --> 00:19:58,600 But can the parachute still bring Buster down safely? 335 00:19:58,600 --> 00:20:00,600 Look at that! 336 00:20:00,600 --> 00:20:01,600 You guys! 337 00:20:01,600 --> 00:20:03,600 You can be flattened out of this! 338 00:20:03,600 --> 00:20:04,600 Oh man! 339 00:20:04,600 --> 00:20:05,600 Oh boy! 340 00:20:05,600 --> 00:20:11,600 Here we go, this is canopy parachute in three, two, one! 341 00:20:13,600 --> 00:20:15,600 Hey!

Yeah, that's it. That's the pieces. 528 00:30:48,600 --> 00:30:49,600 So we have... 529 00:30:49,600 --> 00:30:50,600 That's it for the main shoot. 530 00:30:50,600 --> 00:30:52,600 Now to bring in the reinforcements. 531 00:30:52,600 --> 00:30:59,600 Our next job is to reinforce this hole at the top, which is actually going to bear a large amount of the load. 532 00:30:59,600 --> 00:31:03,600 With a little curtain cord taking up the slack, the last element is the lines. 533 00:31:03,600 --> 00:31:05,600 Almost done. 534 00:31:05,600 --> 00:31:07,600 That's it.

591 00:35:27,600 --> 00:35:29,600 Am I seeing what I'm seeing? 592 00:35:29,600 --> 00:35:31,600 Yeah, that's the peak right there. 593 00:35:31,600 --> 00:35:34,600 Four Gs, he survived the landing without injury. 594 00:35:34,600 --> 00:35:36,600 That's so cool. 595 00:35:36,600 --> 00:35:44,600 Our parachute worked and the best part is Buster received 4.2 Gs, which means not only did he survive, he survived without injury. 596 00:35:44,600 --> 00:35:54,600 However, the problem here is he had way more shower curtains than the criminal would have had, way more time to build it and the criminal didn't have the engineering that we used to make this. 597 00:35:54,600 --> 00:35:57,600 So, even though Buster isn't busted, this myth is. 598 00:35:57,600 --> 00:36:00,600 Next we hook this up to the ironing board and go kite surfing. 599 00:36:00,600 --> 00:36:02,600 Come on. 600 00:36:02,600 --> 00:36:05,600 I can't pull, it's too strong. 601 00:36:07,600 --> 00:36:13,600 After the break, Jamie puts his life on the line. 602 00:36:13,600 --> 00:36:15,600 Here he comes. 603 00:36:15,600 --> 00:36:18,600 But can he motor cross over 4,000 feet of water? 604 00:36:18,600 --> 00:36:20,600 Whoa! 605 00:36:22,600 --> 00:36:27,600 Obviously, if you're going to ride a motorcycle on water, weight is a huge issue as is power. 606 00:36:27,600 --> 00:36:40,600 I'm not sure why I've chosen this particular motorcycle because it's made by a company in Indiana called Service Power Sports and what they do is they take a lightweight aluminum chassis that normally only has a 250 cc engine on it. 607 00:36:40,600 --> 00:36:51,600 Instead, they put a 500 cc high performance two cycle motor on it and that makes it power for pound about as good as you can get in a dirt bike. 608 00:36:51,600 --> 00:36:53,600 It's a rocket. 609 00:36:57,600 --> 00:36:58,600 Welcome back. 610 00:36:58,600 --> 00:37:03,600 All episode long, we have been testing a story that a motorcycle might just be a viable water vehicle. 611 00:37:03,600 --> 00:37:04,600 Seriously. 612 00:37:04,600 --> 00:37:05,600 Whoa! 613 00:37:05,600 --> 00:37:14,600 And with a motorcycle wheel strapped to the outside of a high powered speedboat going 70 miles an hour, it really seemed like there might be something to this story. 614 00:37:14,600 --> 00:37:15,600 Yeah! 615 00:37:15,600 --> 00:37:23,600 So then we got a professional motocross rider and we gave him 100 feet of open water to cross and he was able to do it. 616 00:37:23,600 --> 00:37:25,600 Wow! 617 00:37:26,600 --> 00:37:27,600 Yeah! 618 00:37:27,600 --> 00:37:29,600 But now Mr. Heineman has a brand new question. 619 00:37:29,600 --> 00:37:38,600 Is the motorcycle skipping across the water on its own momentum or does it have enough power to continue indefinitely and Jamie wants to try it? 620 00:37:38,600 --> 00:37:39,600 Yep. 621 00:37:39,600 --> 00:37:43,600 While Eric crossed a mere 100 feet, Jamie wants more. 622 00:37:43,600 --> 00:37:45,600 It's a nice flat run. 623 00:37:45,600 --> 00:37:51,600 He wants to see if the bike can get such a grip on the water that he can speed across the entire lake. 624 00:37:52,600 --> 00:37:59,600 To do so, he'll literally be putting his life on the line, but not without some modifications. 625 00:38:01,600 --> 00:38:07,600 First, the run up to the water needs to be smoother to let Jamie really let rip. 626 00:38:07,600 --> 00:38:09,600 I think that ought to do it. 627 00:38:09,600 --> 00:38:14,600 Then the bike needs a floatation device so it doesn't drag him to the bottom if he fails. 628 00:38:14,600 --> 00:38:18,600 I believe I've got enough floatation here to make it float. 629 00:38:18,600 --> 00:38:20,600 Maybe. 630 00:38:20,600 --> 00:38:24,600 And finally, a lifeguard team is on standby. 631 00:38:26,600 --> 00:38:33,600 This is where it's all about to happen, but what exactly is going to happen here to transition between land and water? 632 00:38:33,600 --> 00:38:39,600 By the time Jamie reaches this point, he should be going between 55 and 75 miles per hour when he enters the water. 633 00:38:39,600 --> 00:38:45,600 Could he just skip all the way across the water to the opposite side of the lake about three quarters of a mile away? 634 00:38:45,600 --> 00:38:53,600 Or could he plant himself right here and just start flying and become his own cautionary Discovery Channel documentary about what not to do? 635 00:38:54,600 --> 00:38:58,600 It's one of the most dangerous experiments in Mythbusters history. 636 00:39:02,600 --> 00:39:03,600 Here he comes. 637 00:39:07,600 --> 00:39:10,600 At great next speed, Jamie hits the water and then... 638 00:39:12,600 --> 00:39:14,600 ...is man over bike. 639 00:39:15,600 --> 00:39:16,600 Let's go over to him. 640 00:39:16,600 --> 00:39:18,600 Adam and the medic team rush in. 641 00:39:20,600 --> 00:39:21,600 He's good. 642 00:39:21,600 --> 00:39:26,600 But it'll take more than a 70-mile-an-hour high dive to hurt the Heinemann. 643 00:39:26,600 --> 00:39:27,600 You all right, sir? 644 00:39:28,600 --> 00:39:29,600 I'm just fine. 645 00:39:30,600 --> 00:39:35,600 I think it did a little bit of a...what is it, a half gain or something? 646 00:39:38,600 --> 00:39:40,600 Definitely no broken bones or anything, so... 647 00:39:40,600 --> 00:39:41,600 Good. 648 00:39:41,600 --> 00:39:44,600 The good news is that Jamie's fighting fit. 649 00:39:44,600 --> 00:39:49,600 The bad news is that he traveled only 80 feet, far less than Eric's effort. 650 00:39:49,600 --> 00:39:50,600 So what went wrong? 651 00:39:50,600 --> 00:39:53,600 There's one of those cases where if it ain't broke, don't fix it. 652 00:39:53,600 --> 00:39:58,600 We added this foam just so that we could retrieve the bike without drowning it afterwards. 653 00:39:58,600 --> 00:40:10,600 But it turned out that the spray coming up off of the wheel was providing a certain amount of lift back here, which in turn made more stress on the front wheel, which made it plunge and made me do a somersault. 654 00:40:10,600 --> 00:40:13,600 So I'm going to go back to the original type of bike. 655 00:40:13,600 --> 00:40:18,600 We have a second one and have another try. 656 00:40:19,600 --> 00:40:21,600 You heard that right. 657 00:40:21,600 --> 00:40:23,600 Jamie's getting straight back on the horse. 658 00:40:23,600 --> 00:40:24,600 Power. 659 00:40:24,600 --> 00:40:28,600 And what's more, this time he's upping the speed to 80. 660 00:40:30,600 --> 00:40:34,600 But will that allow him to burn Aqua all the way across? 661 00:40:40,600 --> 00:40:41,600 Oh! 662 00:40:44,600 --> 00:40:45,600 He's good! 663 00:40:45,600 --> 00:40:46,600 Beautiful! 664 00:40:47,600 --> 00:40:49,600 That was amazing. 665 00:40:49,600 --> 00:40:51,600 It seemed to go on forever. 666 00:40:51,600 --> 00:40:53,600 It's riding, riding, riding, riding. 667 00:40:53,600 --> 00:40:56,600 That's like easily 300 feet or more, buddy. 668 00:40:56,600 --> 00:40:57,600 That was amazing. 669 00:40:58,600 --> 00:40:59,600 He's a cake. 670 00:41:03,600 --> 00:41:04,600 How you feelin'? 671 00:41:05,600 --> 00:41:08,600 Relieved it's over and I'm alive. 672 00:41:10,600 --> 00:41:17,600 Incredibly, Jamie hit the water, throttled the throttle and surfed for over 300 feet. 673 00:41:17,600 --> 00:41:25,600 And while he wasn't able to get a good enough grip to carry on across, it's still myth well and truly confirmed. 674 00:41:25,600 --> 00:41:29,600 In case there's any doubt, I'm standing on the bike. 675 00:41:29,600 --> 00:41:31,600 It's in about 8 feet of water maybe. 676 00:41:31,600 --> 00:41:36,600 So I was riding on water for about 300 feet. 677 00:41:41,600 --> 00:41:46,600 So, riding a motorcycle across the water, busted, plausible or confirmed? 678 00:41:46,600 --> 00:41:47,600 Confirmed. 679 00:41:47,600 --> 00:41:49,600 Not recommended but it's confirmed. 680 00:41:49,600 --> 00:41:51,600 Yes, but only for 300 feet. 681 00:41:51,600 --> 00:41:53,600 I was hoping for further. 682 00:41:53,600 --> 00:41:55,600 I'll settle for that. 683 00:41:56,600 --> 00:41:58,600 And so will we. 684 00:41:58,600 --> 00:42:02,600 So why not cue the music for a motor cross water montage? 685 00:42:10,600 --> 00:42:19,600 That was amazing.
