70 00:03:25,000 --> 00:03:28,000 Well, it's called a two-stage airbag and it works thusly. 71 00:03:28,000 --> 00:03:31,000 The first stage, this top part, slows you down by popping, 72 00:03:31,000 --> 00:03:34,000 by opening through this very portal that I climbed out of. 73 00:03:34,000 --> 00:03:37,000 The second stage, that bottom layer, stops you. 74 00:03:37,000 --> 00:03:39,000 It does not deflate. 75 00:03:40,000 --> 00:03:43,000 And that's key because the name of this game is... 76 00:03:43,000 --> 00:03:45,000 Deceleration. 77 00:03:46,000 --> 00:03:49,000 Like they say, it's not the fall that kills you, 78 00:03:49,000 --> 00:03:51,000 it's the sudden stop. 79 00:03:51,000 --> 00:03:53,000 A jump from a height onto a hard surface 80 00:03:53,000 --> 00:03:56,000 will bring you to a stop very quickly. 81 00:03:56,000 --> 00:03:59,000 And it's this sudden impact that is potentially fatal. 82 00:03:59,000 --> 00:04:03,000 But landing on a soft surface maximizes deceleration, 83 00:04:03,000 --> 00:04:06,000 dissipating impact over a longer time, 84 00:04:06,000 --> 00:04:08,000 reducing the risk of injury. 85 00:04:08,000 --> 00:04:11,000 Randy, falling 101, what do we have to know? 86 00:04:11,000 --> 00:04:14,000 When you jump, you want to make sure that you land flat on your back 87 00:04:14,000 --> 00:04:17,000 and use up as much volume as possible. 88 00:04:17,000 --> 00:04:19,000 Awesome, can we get started?

571 00:28:01,000 --> 00:28:06,000 Then they'll compare the accelerometer data with his dive into a dumpster full of foam. 572 00:28:06,000 --> 00:28:12,000 Add with the accelerometer's in position, Buster is hoisted to 20 feet to take his dive. 573 00:28:13,000 --> 00:28:14,000 You ready for this? 574 00:28:14,000 --> 00:28:15,000 Ready when you are. 575 00:28:15,000 --> 00:28:16,000 All right. 576 00:28:16,000 --> 00:28:18,000 Okay, safety control. 577 00:28:18,000 --> 00:28:19,000 Dumb into airbag. 578 00:28:19,000 --> 00:28:21,000 Three, two, one. 579 00:28:24,000 --> 00:28:26,000 A perfect hit. 580 00:28:26,000 --> 00:28:27,000 Works for me. 581 00:28:27,000 --> 00:28:29,000 Nice work, Buster. 582 00:28:29,000 --> 00:28:31,000 Okay, go ahead and hook her up. 583 00:28:31,000 --> 00:28:33,000 Let's see what we got. 584 00:28:33,000 --> 00:28:36,000 And it figures that the figures are good. 585 00:28:36,000 --> 00:28:42,000 The accelerometers work like a charm and this graph right here is a safe drop into the airbag. 586 00:28:42,000 --> 00:28:45,000 Let's hope we get the same thing out of the dumpster, huh? 587 00:28:45,000 --> 00:28:46,000 Yeah. 588 00:28:46,000 --> 00:28:51,000 Yep, now the MythBusters have the data for a safe landing. 589 00:28:51,000 --> 00:28:54,000 Buster registered 11.4 Gs on that test. 590 00:28:54,000 --> 00:29:02,000 A G is one Earth's gravity, so that means that Buster weighed 11.4 times as much as he normally does when the airbag stops. 591 00:29:02,000 --> 00:29:06,000 We know that you can get up and walk away from a jump like that. 592 00:29:06,000 --> 00:29:13,000 What we need to know now is how this compares to our best case scenario, jumping into a dumpster full of foam. 593 00:29:16,000 --> 00:29:18,000 This is our dumpster. 594 00:29:18,000 --> 00:29:26,000 It's empty right now, but soon we're going to fill it full of the softest stuff that we've been able to find and Buster's going to jump into it to make sure it's okay for us. 595 00:29:26,000 --> 00:29:29,000 Go! Be yourself! 596 00:29:29,000 --> 00:29:34,000 R2, I need you to shut down all the compactors on the detention level. 597 00:29:39,000 --> 00:29:45,000 If you got to jump into a dumpster, this right here would be what you'd call a best case real world scenario. 598 00:29:45,000 --> 00:29:49,000 But is it a best case scenario that you could walk away from? 599 00:29:49,000 --> 00:29:54,000 If Buster doesn't survive a fall into this, this movie myth is busted. 600 00:29:54,000 --> 00:29:59,000 Data collection! Dummy into foam in three, two, one! 601 00:30:03,000 --> 00:30:05,000 That looks like it's viable. 602 00:30:05,000 --> 00:30:08,000 And a closer look at the data backs Adam up. 603 00:30:08,000 --> 00:30:11,000 The foam resulted in 9.9 Gs. 604 00:30:11,000 --> 00:30:16,000 Wow, it's effectively the same, even a little more gentle with the foam. 605 00:30:16,000 --> 00:30:23,000 Yep, from 20 feet, Buster's impact into the foam was 1.5 Gs fewer than his fall into the airbag, 606 00:30:23,000 --> 00:30:30,000 meaning that the foam actually worked better to maximize his deceleration and keep him from injury. 607 00:30:30,000 --> 00:30:34,000 I'm pretty impressed with the foam. I'd say that that is a survivable fall. 608 00:30:34,000 --> 00:30:37,000 Maybe even comfortable when the data backs it up. 609 00:30:37,000 --> 00:30:40,000 Can I be the one to do the jump?
