You all ready? 337 00:17:04,280 --> 00:17:05,280 I'm ready. 338 00:17:05,280 --> 00:17:06,280 Okay, go. 339 00:17:07,280 --> 00:17:12,280 After so many false starts and so much controversy, is that a flying plane? 340 00:17:12,280 --> 00:17:17,280 That is a flying plane, and it was on the paper when it took off. 341 00:17:17,280 --> 00:17:18,280 Excellent. 342 00:17:18,280 --> 00:17:23,280 Confounding and confusing, the plane didn't stay where it was. 343 00:17:23,280 --> 00:17:28,280 It moved forward and took off before the end of the conveyor belt. 344 00:17:28,280 --> 00:17:35,280 Here's the thing. If the myth is that a plane on a conveyor belt can't take off, we just had a plane on a conveyor belt and it took off. 345 00:17:37,780 --> 00:17:42,780 And what's more, they have a theory as to why. 346 00:17:44,780 --> 00:17:48,780 Alright, I'm trying to use this car to demonstrate where I think people get mixed up. 347 00:17:48,780 --> 00:17:53,780 The forward speed of the car is exactly the same as the backward speed of the conveyor belt, thus the car remains stationary. 348 00:17:53,780 --> 00:17:58,780 And this is why people think that the plane's not taking off, because there it is, the stationary's not moving. 349 00:17:58,780 --> 00:18:01,780 Yeah, but cars and airplanes move by different means. 350 00:18:02,500 --> 00:18:07,500 If the air is sending power to its wheels, that's what makes it move forward or backward or keep up with the conveyor belt. 351 00:18:07,500 --> 00:18:14,500 Airplanes have free spinning wheels, and they move because there's a propeller pushing air, which makes the airplane go forward. 352 00:18:15,500 --> 00:18:26,500 Exactly. So, if I remove power to the wheels of this car, thus turning it into a plane, and then my hand pushing will represent the force of the propeller pushing against the air, and I feel almost no resistance on the conveyor belt. 353 00:18:27,500 --> 00:18:29,500 So the plane moves forward. 354 00:18:29,500 --> 00:18:30,500 And it takes off. 355 00:18:30,500 --> 00:18:31,500 Exactly. 356 00:18:31,780 --> 00:18:33,780 So let's get this straight. 357 00:18:33,780 --> 00:18:38,780 A car gets its thrust through its wheels, creating forward motion using the ground it's on. 358 00:18:39,780 --> 00:18:49,780 But a plane gets its thrust through its engines, which are independent of its wheels, and so is not affected by the ground, or in this case, the conveyor belt. 359 00:18:49,780 --> 00:18:52,780 When engines are on, forward motion will happen. 360 00:18:53,780 --> 00:18:54,780 That's the theory. 361 00:18:54,780 --> 00:19:03,780 But to cement their place in history, the Mythbusters are going full scale with a manned aircraft, and the mother of all conveyor belts. 362 00:19:03,780 --> 00:19:06,780 The question is, will they get airborne? 363 00:19:10,780 --> 00:19:14,780 Back at Roche HQ, the 1000 Rad Radiation Test is over. 364 00:19:16,780 --> 00:19:19,780 Free flies are still moving. Fire beetles still moving. 365 00:19:20,780 --> 00:19:21,780 Crack roaches still moving. 366 00:19:22,780 --> 00:19:27,780 Remarkably, all the bugs seem to be alive, well at least for now. 367 00:19:28,780 --> 00:19:39,780 Because radiation works on a cellular level, exposure may not take effect immediately, so each set of bugs is put into containers, which will then be monitored over a 30 day period. 368 00:19:41,780 --> 00:19:47,780 We just did our first test at 1000 Rad. The bugs look alright, so we're moving on to the second test, which is 10,000 Rad. 369 00:19:48,780 --> 00:19:53,780 So in test 2, the dial gets cranked up by a factor of 10. 370 00:19:58,780 --> 00:20:01,780 It's affecting the cameras, but luckily it isn't affecting Grant. 371 00:20:03,780 --> 00:20:16,780 I have to admit that it is a little freaky to go into the room, but I'm starting to understand that just because we subject the bugs to radiation, doesn't make them radioactive. 372 00:20:17,780 --> 00:20:20,780 They're still moving. Nice. 373 00:20:21,780 --> 00:20:29,780 Just like last time, they're all still alive, even after 10,000 Rad. But only time will tell how long these bugs will last. 374 00:20:32,780 --> 00:20:41,780 Now we're going to step it up. We're going to 100,000 Rad. That is 100 times the lethal dose for a human. That is melting faces at the end of Raiders of the Lost Ark scaring. 375 00:20:41,780 --> 00:20:42,780 Let's zap them. 376 00:20:43,780 --> 00:20:52,780 And while the last set of bugs are being zapped, Raiders of the Lost Ark style, Grant's found out the background to this myth. 377 00:20:57,780 --> 00:21:00,780 Hey, do you know what I found out about the science of radiation? 378 00:21:00,780 --> 00:21:01,780 No, what? 379 00:21:01,780 --> 00:21:18,780 Well, we know that radioactivity was discovered by Henri Becquerel in the late 1880s, but it wasn't until more recently that scientists found out that it's the sensitive tissues like those in our bone marrow or intestinal tract that make us more susceptible to poisoning by radiation than other species. 380 00:21:19,780 --> 00:21:26,780 The theory is that the more simple body structures of the insects should make them less susceptible to radiation than us. 381 00:21:27,780 --> 00:21:33,780 Well, that's the theory. But after the 100,000 Rad test, the news ain't good for the bugs. 382 00:21:34,780 --> 00:21:44,780 Oh my gosh. From the looks of it, there might be like 10% still alive. That's frightening. 383 00:21:44,780 --> 00:21:52,780 Nearly all of Test 3's cockroaches have died. But from the looks of the other bug boxes, this test ain't over yet. 384 00:21:53,780 --> 00:22:01,780 So we've got all of our bugs here that have been exposed to the various levels of radiation, 1,000, 10,000 and 100,000 Rad. 385 00:22:01,780 --> 00:22:09,780 Now we've got a fourth group and that is the control set. The only difference is that they haven't been exposed to any radiation. 386 00:22:09,780 --> 00:22:16,780 We'll be able to use that to compare to the bugs that have been irradiated and see how they do. 387 00:22:17,780 --> 00:22:24,780 So it's back to the show. But the question is, will the bugs survive or will they drop like flies? 388 00:22:27,780 --> 00:22:36,780 It's the sum of all fears. But would cockroaches survive the radiation of a nuclear explosion and inherit the Earth? 389 00:22:36,780 --> 00:22:45,780 In this classic modern myth, Kari Torian Grant have blasted three species of insect with three increasing levels of radiation. 390 00:22:45,780 --> 00:22:49,780 Will the cockroach be the ultimate survivor? 391 00:22:49,780 --> 00:22:53,780 Hopefully they haven't mutated into some crazy monsters. 392 00:22:53,780 --> 00:22:56,780 Back at the shop, what's the bug bulletin? 393 00:22:56,780 --> 00:23:05,780 Okay, so here's the plan. We have 12 boxes of insects. Four cockroaches, four flower beetles and four fruit flies. 394 00:23:05,780 --> 00:23:10,780 We'll be monitoring them over the next 30 days counting how many die. 395 00:23:10,780 --> 00:23:17,780 The job of insect coroner may sound grim, but for the mythbusters, it's important to keep upbeat. 396 00:23:21,780 --> 00:23:22,780 We've got a breach. 397 00:23:22,780 --> 00:23:28,780 And what's more, they're making sure the bugs on death row are being well looked after. 398 00:23:28,780 --> 00:23:34,780 They'll be given all the food and water they need and we'll check in on the 15-day and 30-day increments. 399 00:23:34,780 --> 00:23:38,780 And we'll see if the cockroach is in fact the ultimate survivor. 400 00:23:38,780 --> 00:23:44,780 So with two weeks to wait until the next dead count, the team needs something else to do. 401 00:23:44,780 --> 00:23:49,780 Coming up, will the mythbusters feel the wind beneath their wings? 402 00:23:49,780 --> 00:23:50,780 Oh crap. 403 00:23:50,780 --> 00:23:55,780 But first, the team scrutinize a soapy internet story. 404 00:23:55,780 --> 00:23:58,780 Oh my God! Crack! Crack! Get over here! Look at this! 405 00:24:08,780 --> 00:24:12,780 And this is perfect. A foamy fable straight from the fan site. 406 00:24:14,780 --> 00:24:16,780 One, two, three. 407 00:24:18,780 --> 00:24:20,780 What the hell are we doing this for? 408 00:24:20,780 --> 00:24:25,780 There is actually a myth associated with it. If you take a can of shaving cream and freeze it, 409 00:24:25,780 --> 00:24:30,780 if you take off the outside, put it in someone's car, it'll expand to fill the car. 410 00:24:31,780 --> 00:24:37,780 Shaving cream is a practical joke staple for any frat boy funster or perky prankster. 411 00:24:37,780 --> 00:24:45,780 But as the internet rumor suggests, could one can of frozen shaving cream really inflate to fill a car? 412 00:24:45,780 --> 00:24:49,780 The first step in this myth is to freeze the can of shaving cream. 413 00:24:51,780 --> 00:24:55,780 I'll leave it in there for a few hours and while that's freezing, I'm going to go get cleaned up. 414 00:24:57,780 --> 00:25:00,780 Alright, I have my shaving cream, it's frozen solid. 415 00:25:00,780 --> 00:25:03,780 Now all I need to do is cut off the can, hopefully it won't explode in my face. 416 00:25:03,780 --> 00:25:07,780 What I should be left with is a cylinder of frozen shaving cream. 417 00:25:07,780 --> 00:25:13,780 And I'll stick that into the car and hopefully as it starts to thaw, it'll expand and fill up the whole car. 418 00:25:13,780 --> 00:25:15,780 Quick, close the door! 419 00:25:16,780 --> 00:25:19,780 This caper promises a car bursting with bubbles. 420 00:25:19,780 --> 00:25:26,780 But, Tori's scoring this myth low on the prankometer. Lower even than the infamous biscuit bullet. 421 00:25:27,780 --> 00:25:29,780 This is probably the lamest prank I've ever seen. 422 00:25:29,780 --> 00:25:32,780 There's no way this can of shaving cream is going to fill the entire car. 423 00:25:33,780 --> 00:25:37,780 Obviously, Tori thinks this fansite toiletry tale stinks. 424 00:25:38,780 --> 00:25:40,780 But five hours later... 425 00:25:40,780 --> 00:25:43,780 Oh my god! Grant! Grant! Get over here! Look at this! 426 00:25:43,780 --> 00:25:45,780 What? What? What? 427 00:25:47,780 --> 00:25:48,780 Nothing. 428 00:25:48,780 --> 00:25:50,780 That is so un-amazing. 429 00:25:51,780 --> 00:25:54,780 Clearly they're unimpressed with the foam's lack of inflation. 430 00:25:55,780 --> 00:25:58,780 But these merry pranksters aren't done yet. 431 00:25:58,780 --> 00:26:00,780 I'm a lame prank. 432 00:26:00,780 --> 00:26:03,780 You know, we did buy 50 cans. 433 00:26:03,780 --> 00:26:05,780 Yeah! 434 00:26:06,780 --> 00:26:10,780 So it's take two. At this time, it's 50 cans into the freezer. 435 00:26:11,780 --> 00:26:13,780 And quick as a flash. 436 00:26:15,780 --> 00:26:17,780 Alright, we gotta move fast. 437 00:26:17,780 --> 00:26:19,780 These things are gonna start to frost it. 438 00:26:20,780 --> 00:26:26,780 It's a race against time as Grant and Tori grind open all 50 frozen cans. 439 00:26:27,780 --> 00:26:28,780 Okay. 440 00:26:29,780 --> 00:26:35,780 But once the car's loaded up, the hours pass in the blink of an eye. 441 00:26:35,780 --> 00:26:37,780 Oh! 442 00:26:37,780 --> 00:26:39,780 You know what? Nothing. 443 00:26:39,780 --> 00:26:43,780 Well, but you know what? That's expanded a lot more than I thought it would. 444 00:26:44,780 --> 00:26:47,780 This isn't a prank. It's a minor inconvenience. 445 00:26:48,780 --> 00:26:51,780 Fans suggested shaving foam. And it's a flop. 446 00:26:52,780 --> 00:26:56,780 But rest assured, the mythbusters have a last plan up their sleeve. 447 00:26:56,780 --> 00:26:59,780 The next step is we're gonna ramp it up. 448 00:26:59,780 --> 00:27:05,780 We are going to create a situation where foam is going to come out of the windows. 449 00:27:06,780 --> 00:27:08,780 Possibly explode the car. 450 00:27:26,780 --> 00:27:31,780 And in 2008, millions are clashing over the myth of plane on a conveyor belt. 451 00:27:33,780 --> 00:27:34,780 Excellent! 452 00:27:36,780 --> 00:27:39,780 That little airplane took off just like I thought it would. 453 00:27:39,780 --> 00:27:41,780 So myth buster, right? 454 00:27:41,780 --> 00:27:44,780 Not so fast, man. You know we can't leave it there. 455 00:27:44,780 --> 00:27:49,780 You know this debate would never be quelled until you and I did it full scale. 456 00:27:49,780 --> 00:27:51,780 And that's just what we have to do. 457 00:27:51,780 --> 00:27:52,780 Well, you know what that means. 458 00:27:52,780 --> 00:27:57,780 Yes, I do. It means a real plane and it means a really big conveyor belt. 459 00:27:59,780 --> 00:28:01,780 And hey presto, this should do it. 460 00:28:01,780 --> 00:28:08,780 A 2,000 foot length of tarpaulin, which they can drag behind a truck to create the biggest conveyor belt in history. 461 00:28:09,780 --> 00:28:13,780 And with that sorted, they cruise down to Castle Airport. 462 00:28:14,780 --> 00:28:16,780 I love it. That thing's great. 463 00:28:17,780 --> 00:28:23,780 Where they meet the other ingredient for this myth, kamikaze ultralight pilot, Mark Johnson. 464 00:28:23,780 --> 00:28:25,780 It's the Cadillac of ultralights. 465 00:28:25,780 --> 00:28:29,780 It's 400 pounds, the engine's 100, so the plane itself's only 300. 466 00:28:29,780 --> 00:28:34,780 And it'll take off straight up, 1200 feet a minute. It's quite amazing. 467 00:28:34,780 --> 00:28:38,780 It's amazing, but will it take off on the conveyor belt? 468 00:28:39,780 --> 00:28:44,780 It's bigger scale and a bigger challenge with Mark's life on the line. 469 00:28:44,780 --> 00:28:51,780 Just like in small scale, the mythbusters need distance and speed measurements to get this myth off the ground. 470 00:28:51,780 --> 00:28:54,780 All right, distance to take off. Good to go. 471 00:28:54,780 --> 00:29:00,780 Jamie gives clearance. Mark floors it. And in no time at all. 472 00:29:01,780 --> 00:29:05,780 Take off distance, 85 feet. That's fantastic for us. 473 00:29:07,780 --> 00:29:08,780 Fantastic. 474 00:29:08,780 --> 00:29:11,780 Next, the guys need the take off speed. 475 00:29:12,780 --> 00:29:16,780 We've got the cockpit camera that we put on the airspeed indicator in miles per hour. 476 00:29:16,780 --> 00:29:19,780 Let's see what its take off speed was. 477 00:29:19,780 --> 00:29:20,780 That was... 478 00:29:20,780 --> 00:29:22,780 Yeah, about 25 miles an hour. 479 00:29:22,780 --> 00:29:27,780 And with speed and distance covered, it's time to launch full scale. 480 00:29:27,780 --> 00:29:32,780 First up, Mark's ultralight will be moved onto the tarpaulin treadmill. 481 00:29:32,780 --> 00:29:35,780 Then Jamie will attach his pickup to the end of the tarp. 482 00:29:35,780 --> 00:29:42,780 He'll pull it at 25 miles per hour in the opposite direction to the ultralight, just as Mark tries to take off. 483 00:29:43,780 --> 00:29:46,780 That's the plan. So where's the tarp? 484 00:29:46,780 --> 00:29:56,780 We've got 2,000 feet of 12 foot wide tarp, which we're going to drag behind Jamie's pickup truck, effectively making the world's biggest conveyor belt. 485 00:29:57,780 --> 00:30:02,780 It's a simple plan, which Adam, playing the role of the airplane, demonstrates. 486 00:30:03,780 --> 00:30:06,780 But there's trouble when he rips holes in the tarp. 487 00:30:06,780 --> 00:30:07,780 Sorry. 488 00:30:07,780 --> 00:30:09,780 And that's not the only problem. 489 00:30:10,780 --> 00:30:13,780 So it's not as simple as we thought. The wind's shifting down the runway. 490 00:30:13,780 --> 00:30:18,780 It's only about 10 or 15 degrees, but each time it shifts, it's throwing this whole thing in a tizzy. 491 00:30:19,780 --> 00:30:23,780 It seems traditional myth buster patients has gone with the wind. 492 00:30:24,780 --> 00:30:27,780 You're going to stop. I don't know where the f*** you're going. 493 00:30:28,780 --> 00:30:32,780 If this wind is heading up the runway, we can't do anything. It's f***ing... 494 00:30:33,780 --> 00:30:36,780 Well, as you can see, the wind has picked up. It's causing us a big problem. 495 00:30:36,780 --> 00:30:39,780 So we're out of here. We're going to be back early in the morning. 496 00:30:40,780 --> 00:30:47,780 It's the most requested fan myth ever, so failure to launch is not an option for the myth busters. 497 00:30:47,780 --> 00:30:51,780 Tomorrow is their last chance to blow away this myth. 498 00:30:58,780 --> 00:31:02,780 To answer the question, will cockroaches inherit the earth after a nuclear blast? 499 00:31:03,780 --> 00:31:11,780 Cary, Tori and Grant have exposed cockroaches, fruit flies and flower beetles to terrifyingly high levels of radiation. 500 00:31:12,780 --> 00:31:13,780 Tricky little b***. 501 00:31:14,780 --> 00:31:16,780 And at the halfway mark of the experiment... 502 00:31:17,780 --> 00:31:18,780 Oh, stinks! 503 00:31:20,780 --> 00:31:22,780 The death toll is mounting. 504 00:31:22,780 --> 00:31:29,780 But with two weeks to go, it's still too early to call which bug will be the ultimate survivor. 505 00:31:30,780 --> 00:31:31,780 What is he doing? 506 00:31:31,780 --> 00:31:34,780 Tori's trying to see if he can hold his breath longer than a cockroach. 507 00:31:34,780 --> 00:31:36,780 Why, do cockroaches hold their breath for a long time? 508 00:31:36,780 --> 00:31:37,780 Yeah, supposedly. 509 00:31:39,780 --> 00:31:40,780 Where's my gun? 510 00:31:40,780 --> 00:31:41,780 Eight seconds. 511 00:31:41,780 --> 00:31:47,780 Well, if you want to see how long cockroaches can hold their breath, log on to discovery.com slash mythbusters and check it out. 512 00:31:53,780 --> 00:31:59,780 I have the only remaining life form to have survived a hundred thousand rad dose of radiation. 513 00:32:09,780 --> 00:32:11,780 Practical jokes are great fun. 514 00:32:12,780 --> 00:32:13,780 As long as they work. 515 00:32:15,780 --> 00:32:21,780 But as we've seen, the foam fizzer from the fan site barely registered on the prankometer. 516 00:32:21,780 --> 00:32:24,780 This is probably the lamest prank I've ever seen. 517 00:32:24,780 --> 00:32:26,780 It's of microscopic proportions. 518 00:32:26,780 --> 00:32:34,780 So now the team is taking it to absolute max with 25 gallons of something called AB foam. 519 00:32:34,780 --> 00:32:36,780 AB foam comes as a liquid. 520 00:32:36,780 --> 00:32:37,780 It's two parts. 521 00:32:37,780 --> 00:32:42,780 You mix equal parts together and then you have about 30 seconds of mixing time before it starts expanding and foaming up. 522 00:32:42,780 --> 00:32:48,780 But once it sets, after about 20 minutes, it's a hard, rigid, dense foam. 523 00:32:49,780 --> 00:32:58,780 In fact, it's so quick to expand and so cohesive that when Adam and Jamie blew up a plane, they used AB foam to seal the deal. 524 00:32:59,780 --> 00:33:01,780 Attention, the plane is alive. 525 00:33:04,780 --> 00:33:09,780 But when AB foam is mixed, it gives off heat in an exothermic reaction. 526 00:33:09,780 --> 00:33:14,780 And with 25 gallons of the stuff, that's even got Tori worried. 527 00:33:14,780 --> 00:33:16,780 We're going to take some safety precautions. 528 00:33:16,780 --> 00:33:17,780 We're going to empty out the gas. 529 00:33:17,780 --> 00:33:18,780 We're going to empty out the oil. 530 00:33:18,780 --> 00:33:21,780 We have some fire extinguishers standing by. 531 00:33:21,780 --> 00:33:27,780 If it does catch on fire, it can burn itself out and no structures will be in danger. 532 00:33:31,780 --> 00:33:37,780 25 gallons of liquid is equivalent to around 3.5 cubic feet. 533 00:33:38,780 --> 00:33:46,780 But once mixed, will the chemical foam swell up enough to fill the 90 cubic feet of space inside the car? 534 00:33:46,780 --> 00:33:50,780 One thing's for sure, there's no time to consider details. 535 00:33:51,780 --> 00:33:55,780 Once you start mixing, there's no like waiting and oops I did it wrong. 536 00:33:55,780 --> 00:33:57,780 No, you have to go and you have to go immediately. 537 00:33:57,780 --> 00:34:02,780 Once this thing starts to go, you've got to get as many kits in there as possible. 538 00:34:02,780 --> 00:34:11,780 There are absolutely no second chances in this test because in a matter of seconds, this luxury sedan is stuffed full of foam. 539 00:34:11,780 --> 00:34:17,780 This is more than a prank. This is evil. This is a car that will never ever drive again. 540 00:34:17,780 --> 00:34:20,780 Just to show you how rigid this foam is. 541 00:34:26,780 --> 00:34:27,780 Look at that. 542 00:34:28,780 --> 00:34:30,780 Solid. Solid. 543 00:34:30,780 --> 00:34:32,780 That is a mean, mean thing to do. 544 00:34:33,780 --> 00:34:37,780 Yeah, we did it. We filled the car up with AB foam. 545 00:34:37,780 --> 00:34:41,780 The dreams come true. I've always wanted to see this and now I have. 546 00:34:41,780 --> 00:34:45,780 You know, the shaving cream wasn't that great of a joke. 547 00:34:45,780 --> 00:34:49,780 So we ramped it up and this is what we came up with. 548 00:34:49,780 --> 00:34:55,780 I'm totally satisfied. I know if I walked up to my car and it looked like that, I'd be pretty upset. 549 00:34:55,780 --> 00:34:58,780 It would ruin my day, not to mention my car. 550 00:34:58,780 --> 00:35:03,780 Oh, and anybody thinking of pranking the team, here's some tough talk for you. 551 00:35:05,780 --> 00:35:07,780 Don't mess with us. That's what you get. 552 00:35:18,780 --> 00:35:22,780 Carrie, Tori and Grant have been playing with deadly radiation. 553 00:35:22,780 --> 00:35:26,780 Captain, I recommend we set all phasers to stud. 554 00:35:28,780 --> 00:35:35,780 They've exposed cockroaches, fruit flies and flower beetles to three levels of this invisible killer. 555 00:35:35,780 --> 00:35:40,780 But which one will be crowned the ultimate survivor? 556 00:35:41,780 --> 00:35:45,780 That was a month ago and ever since they've been counting the dead. 557 00:35:45,780 --> 00:35:46,780 Ten. 558 00:35:46,780 --> 00:35:48,780 Oh, no hit on that one. 559 00:35:49,780 --> 00:35:51,780 It's been a morbid 30 days. 560 00:35:51,780 --> 00:35:56,780 But remember, these insects were always bred for death by science. 561 00:35:58,780 --> 00:36:03,780 Just like Tori, the insects have been hit hard, but there are survivors. 562 00:36:04,780 --> 00:36:07,780 You know, this is crazy. This is the 10,000 rad. 563 00:36:07,780 --> 00:36:13,780 This is 10 times the lethal dose for humans and look how many cockroaches are still kicking. 564 00:36:13,780 --> 00:36:16,780 And the flower beetles have gone one better. 565 00:36:16,780 --> 00:36:23,780 I have here in my hand the only remaining life form to have survived a hundred thousand rad dose of radiation. 566 00:36:23,780 --> 00:36:25,780 The flower beetle. 567 00:36:25,780 --> 00:36:29,780 So is this myth busted or confirmed? 568 00:36:29,780 --> 00:36:31,780 And done. 569 00:36:31,780 --> 00:36:37,780 Okay, so the idea was that cockroaches would be the only thing to survive a nuclear blast. What do we get? 570 00:36:37,780 --> 00:36:40,780 Well, remarkably, cockroaches are really good survivors. 571 00:36:40,780 --> 00:36:44,780 After 30 days, the ones exposed to 10,000 rad still had 30% still alive. 572 00:36:44,780 --> 00:36:49,780 And the ones exposed to a thousand rad had 50% still alive. It's pretty amazing. 573 00:36:49,780 --> 00:36:53,780 That's incredible. Considering if we were exposed to a thousand rad, we'd be dead. 574 00:36:53,780 --> 00:36:57,780 So it's confirmed. Cockroaches out-survived humans after a nuclear blast. 575 00:36:57,780 --> 00:37:01,780 True, but we tested three types of insects and the other two did much better than cockroaches. 576 00:37:01,780 --> 00:37:04,780 Yeah, the fruit flies did really well until they died of natural causes. 577 00:37:04,780 --> 00:37:06,780 And then the flower beetles, well, they were the strongest. 578 00:37:06,780 --> 00:37:11,780 After being exposed to a hundred thousand rad, which is a hundred times the amount that would kill us, 579 00:37:11,780 --> 00:37:13,780 they were still 10% alive. 580 00:37:13,780 --> 00:37:17,780 The cockroaches, there was none that survived after that kind of exposure. 581 00:37:17,780 --> 00:37:21,780 So the final result is that all the insects out-survived humans, 582 00:37:21,780 --> 00:37:26,780 but as far as inheriting the Earth, there are much better candidates than the cockroach. 583 00:37:26,780 --> 00:37:28,780 Which means it's busted. 584 00:37:28,780 --> 00:37:31,780 Busted, just like our chances of reproducing. 585 00:37:35,780 --> 00:37:41,780 Up next, they're cleared for takeoff, but will they settle the squabble surrounding the myth? 586 00:37:41,780 --> 00:37:46,780 All right, this is full-size airplane on a conveyor belt, for real this time! 587 00:37:52,780 --> 00:37:58,780 In 100 years of flight, man has tried to get off the ground in some inventive ways. 588 00:38:01,780 --> 00:38:06,780 But none have caused such heated public debate as this flight of fancy. 589 00:38:07,780 --> 00:38:13,780 If a manned airplane is on a conveyor belt and both are going at the airplane's takeoff speed, 590 00:38:13,780 --> 00:38:17,780 but in opposite directions, will the plane be held where it is? 591 00:38:17,780 --> 00:38:19,780 Or will it take off? 592 00:38:21,780 --> 00:38:24,780 Yesterday, big scale hit big problems. 593 00:38:24,780 --> 00:38:28,780 The crosswind blew away any chance of a test. 594 00:38:28,780 --> 00:38:32,780 If this wind is heading up the runway, we can't do anything. 595 00:38:35,780 --> 00:38:39,780 It's dawn on the tarmac, and that's why we're here, because there's no wind. 596 00:38:39,780 --> 00:38:42,780 We're told the first couple of hours of the morning. 597 00:38:42,780 --> 00:38:45,780 We are not going to be able to fly. 598 00:38:45,780 --> 00:38:48,780 We're going to be the first couple of hours of the morning. 599 00:38:48,780 --> 00:38:51,780 We are hauling ass because the tarp is perfect right now. 600 00:38:51,780 --> 00:38:54,780 It's like making a very big bed. 601 00:38:54,780 --> 00:39:00,780 With less than a guff of air movement, you could say the mythbusters have broken wind. 602 00:39:00,780 --> 00:39:02,780 This is looking great. 603 00:39:02,780 --> 00:39:05,780 But another discovery could seriously jeopardize this test. 604 00:39:05,780 --> 00:39:08,780 Yesterday, while Jamie was driving, just a little slow speed, 605 00:39:08,780 --> 00:39:11,780 I decided to run on the tarp because it thought it would be funny. 606 00:39:11,780 --> 00:39:15,780 But every time I foot hit the tarp, it tore a huge hole in it. 607 00:39:15,780 --> 00:39:18,780 That's what I'm picturing as the worst case scenario. 608 00:39:18,780 --> 00:39:22,780 But the moment that plane starts to roll and Jamie starts to drive in the opposite direction, 609 00:39:22,780 --> 00:39:25,780 the tarp just, whoosh, just rips all the hell. 610 00:39:25,780 --> 00:39:30,780 Even though he's facing a bizarre conveyor belt death, Mark seems unflappable. 611 00:39:30,780 --> 00:39:35,780 But with ten years of flying experience, what does he think of the myth?
