I think we're good to go. 385 00:20:24,240 --> 00:20:28,240 Then Jamie starts the nasal drip and leaves Adam to some modeling. 386 00:20:28,240 --> 00:20:32,240 I'm ready to start constructing. I'll start the timer now. 387 00:20:32,240 --> 00:20:33,240 Good luck. 388 00:20:33,240 --> 00:20:35,240 Thanks. 389 00:20:35,240 --> 00:20:41,240 Remember, they're testing to see if Adam's pseudo snot will spread far and wide. 390 00:20:41,240 --> 00:20:49,240 And after an hour of building, gluing and wiping, 60 milliliters of fluid has dripped through the nose rig. 391 00:20:49,240 --> 00:20:54,240 Okay, so time's up. We get to see how far your nasal secretions went. 392 00:20:54,240 --> 00:20:57,240 Excellent. All right, let's do it. 393 00:20:57,240 --> 00:20:59,240 Da-da-da! 394 00:21:00,240 --> 00:21:07,240 Oh my gosh, look at that. That is...wait, look at my face. 395 00:21:07,240 --> 00:21:13,240 That's disgusting! Am I like, just covered with it? 396 00:21:13,240 --> 00:21:14,240 You are. 397 00:21:14,240 --> 00:21:23,240 The table, the plane and Adam are lit up like a dance party with a trail of snot or neon dye on everything Adam has touched. 398 00:21:23,240 --> 00:21:28,240 Well, we set out to construct an experiment whereby we can track my nasal secretions and I have to say, 399 00:21:28,240 --> 00:21:33,240 I think we've done stunningly. They seem to have gotten absolutely everywhere. 400 00:21:33,240 --> 00:21:36,240 Everything on this table has a little touch of orange on it. 401 00:21:36,240 --> 00:21:41,240 That's the name of my cover band. Touch of Orange. 402 00:21:41,240 --> 00:21:48,240 Obviously, Adam's pseudo snot got everywhere, which is amazing given that it was coming out a tiny droplet at a time. 403 00:21:48,240 --> 00:21:53,240 But what does this mean as far as transmitting a cold virus or a flu? 404 00:21:53,240 --> 00:21:58,240 Well, to find that out, we've got to introduce people and so that's what we're going to do next. 405 00:21:58,240 --> 00:22:05,240 Yep, next, the Mythbusters will track the spread of snot by partying in the name of science. 406 00:22:09,240 --> 00:22:11,240 Don't try anything you see on the show at home. 407 00:22:11,240 --> 00:22:14,240 Wear what you call experts. 408 00:22:15,240 --> 00:22:22,240 In a perfect storm of circumstance, could a tornado turn glass into a guillotine? 409 00:22:22,240 --> 00:22:25,240 Well, not so far. 410 00:22:25,240 --> 00:22:28,240 Okay, so we're struggling with decapitation big time. 411 00:22:28,240 --> 00:22:35,240 Yeah, I mean, throwing a piece of glass accurately even at low speeds is very difficult and the pieces of glass keep shattering. 412 00:22:35,240 --> 00:22:41,240 And it's only going to get harder as we ramp up the speed, something we actually have to do. 413 00:22:41,240 --> 00:22:52,240 Alright, well what if we try this? What if we take our head and neck, put it on the runway, and then we attach a sheet of glass to a vehicle horizontally, drive it the neck, and then release the glass before it hits the neck? 414 00:22:52,240 --> 00:23:03,240 Yes, and if we drive as fast as we can, like 80 miles per hour, and get a bigger sheet of glass, that extra mass plus that speed should equal an impact at over 300 miles an hour. 415 00:23:03,240 --> 00:23:05,240 I love it, let's do it! 416 00:23:06,240 --> 00:23:12,240 So at the Alameda runway, the teams foregoing the throwing to tackle this myth head on. 417 00:23:12,240 --> 00:23:17,240 You guys ready to see if we can make a tornado? Let's do it! 418 00:23:18,240 --> 00:23:24,240 But how will a car going at 80 miles per hour represent a 300 mile an hour tornado? 419 00:23:24,240 --> 00:23:36,240 Now the name of this game is Kinetic Energy. We can't possibly drive at extreme tornado speed, but what we can do is simulate the kinetic energy of a smaller piece of glass flying at those speeds. 420 00:23:36,240 --> 00:23:49,240 Using this giant piece of glass, this has a lot more mass. Now this piece, traveling at only 80 miles per hour, has the same kinetic energy as our smaller piece, traveling at over 300 miles per hour. 421 00:23:49,240 --> 00:23:51,240 I call that extreme tornado speed. 422 00:23:52,240 --> 00:23:56,240 Grant's right, and it's over to Carrie to explain why. 423 00:23:56,240 --> 00:24:03,240 Tori's 450 gram pane of glass, flying at 70 miles an hour, had a kinetic energy of around 220 joules. 424 00:24:03,240 --> 00:24:12,240 If that glass had been traveling at an F5 tornado speed of 300 miles an hour, it would have had the energy of over 4000 joules. 425 00:24:12,240 --> 00:24:18,240 Now because the truck can only drive 80 miles an hour, to get a 4000 joule hit, you need a heavier piece of glass. 426 00:24:18,240 --> 00:24:23,240 So how heavy? 6.5 kilograms. But will that cause a decapitation? 427 00:24:23,240 --> 00:24:33,240 That's one big piece of tornado alley code glass, and to put it to work, Tori's built a rig that looks just as lethal as it is. 428 00:24:33,240 --> 00:24:41,240 So this is the super tornado decapitation rig. So I built this steel structure that we've attached to the truck. 429 00:24:42,240 --> 00:24:47,240 On the end of it is a piece of glass being held oh so gently by these foam blocks. 430 00:24:47,240 --> 00:24:52,240 When we hit the neck, the styrofoam will break and the glass will act as if it's flying through the air. 431 00:24:54,240 --> 00:25:05,240 Now what I need to do is drive towards our neckman as fast as I can and hit that neck, so that when we hit that neck, this piece of glass will break away from the truck, hopefully decapitating our man in confirming this myth. 432 00:25:05,240 --> 00:25:08,240 With neckman's neck on the line. 433 00:25:08,240 --> 00:25:11,240 Holy mackerel, look at that tornado! 434 00:25:13,240 --> 00:25:15,240 It's all systems go. 435 00:25:15,240 --> 00:25:18,240 Okay Tori, belated. Are you ready? 436 00:25:18,240 --> 00:25:22,240 I am in position and ready to go. 437 00:25:22,240 --> 00:25:24,240 You ready? Ready. 438 00:25:24,240 --> 00:25:32,240 Okay, this is neckman versus the large piece of glass in 3, 2, 1. 439 00:25:32,240 --> 00:25:38,240 Not wanting the glass to slip loose, Tori gently accelerates up to 80 miles an hour. 440 00:25:39,240 --> 00:25:41,240 Okay. 441 00:25:41,240 --> 00:25:44,240 That's what I was going to say. 442 00:25:44,240 --> 00:25:48,240 Now is the time I feel compelled to yell duck. 443 00:25:50,240 --> 00:25:55,240 Whoa, that was almost no hesitation whatsoever. 444 00:25:55,240 --> 00:26:00,240 That was gruesome. I mean there was no resistance. The hedge came off. 445 00:26:00,240 --> 00:26:02,240 Alright, let's check it out. 446 00:26:04,240 --> 00:26:10,240 That was incredible. All I heard was a foot and I looked back and I saw his head on the ground. 447 00:26:10,240 --> 00:26:12,240 But he the rig worked. 448 00:26:12,240 --> 00:26:13,240 Yeah. 449 00:26:13,240 --> 00:26:19,240 It's mission accomplished. A nasty decapitation on the very first run as the glass cuts clean through. 450 00:26:19,240 --> 00:26:24,240 But in a mythbusters first, the next step is to ramp the results down. 451 00:26:25,240 --> 00:26:31,240 Now I can't say that I'm surprised by this because that amount of energy contained in that glass troweling that fast 452 00:26:33,240 --> 00:26:36,240 would be like a super tornado. An incredible tornado. 453 00:26:36,240 --> 00:26:41,240 A 300 mile per hour plus wind speed tornado. 454 00:26:41,240 --> 00:26:45,240 And the thing is, you don't have those kinds of tornadoes every day. 455 00:26:45,240 --> 00:26:50,240 So what we're going to do next is actually go at a slower speed, try the same experiment. 456 00:26:50,240 --> 00:26:55,240 This time simulating a more average tornado and see what we get. 457 00:26:55,240 --> 00:26:59,240 So they're going to rerun this test at 40 miles an hour. 458 00:26:59,240 --> 00:27:08,240 And thanks to the marvel of math, we know that the heavy glass going at 40 has the same energy as its smaller counterpart 459 00:27:08,240 --> 00:27:13,240 traveling at 150 miles an hour. A high force to tornado. 460 00:27:14,240 --> 00:27:22,240 But will that be high enough to find out Neckman's cousin, Collar Boy, gets his moment in the sun? 461 00:27:22,240 --> 00:27:28,240 Okay, this is Neckman versus the big piece of glass at 40 miles per hour. Take it away. 462 00:27:28,240 --> 00:27:32,240 Tornado! Tornado! 463 00:27:33,240 --> 00:27:37,240 Yep, look out Collar Boy. There's a storm coming. 464 00:27:38,240 --> 00:27:42,240 Whoa, what was that? 465 00:27:42,240 --> 00:27:49,240 Wow, look at the trail of destruction. We got decapitation and the glass broke away. 466 00:27:49,240 --> 00:27:55,240 At first glance it seems like we've reached myth confirmed as head and neck part company. 467 00:27:57,240 --> 00:28:00,240 But the high speed tells a different story. 468 00:28:01,240 --> 00:28:06,240 It seems that the hair trigger on the glass didn't work cleanly. 469 00:28:06,240 --> 00:28:11,240 And that means that some of the car's own momentum may have affected the outcome. 470 00:28:11,240 --> 00:28:16,240 For this team of perfectionists, it's just not good enough. 471 00:28:16,240 --> 00:28:20,240 We're really bothered by the fact that the glass is not totally dislodging. 472 00:28:20,240 --> 00:28:28,240 And I'm thinking that maybe we're getting some extra mass, some extra force, some extra momentum from the truck being attached to that glass. 473 00:28:28,240 --> 00:28:34,240 So the next obvious myth bustery step? Well we're gonna go build a robot in the shop. 474 00:28:34,240 --> 00:28:39,240 Yep, they're following that old myth buster's mantra. If in doubt, build a robot. 475 00:28:39,240 --> 00:28:44,240 Tornado! 476 00:28:59,240 --> 00:29:02,240 I'm gonna go get you. 477 00:29:06,240 --> 00:29:13,240 Soon I will have six guests, or as I like to call them, test subjects having a party with me under test conditions. 478 00:29:13,240 --> 00:29:17,240 These conditions are, three of my guests are gonna behave as germaphobes. 479 00:29:17,240 --> 00:29:20,240 Three of my guests have no idea what's happening. 480 00:29:20,240 --> 00:29:26,240 I will be spreading my nasal secretions far and wide while performing a series of normal party-like tasks. 481 00:29:26,240 --> 00:29:36,240 Cake, toasts, games, what have you. At the end of all of this, we're gonna flick out the lights, turn on the ultraviolet lights and see how far I've been able to spread my secretions. 482 00:29:36,240 --> 00:29:39,240 Now if you'll excuse me, I need to get into makeup. 483 00:29:40,240 --> 00:29:47,240 So as not to reveal what's being tested to our guest guinea pigs, special effects artist Danny gives Adam a nose job. 484 00:29:47,240 --> 00:29:51,240 Oh, it's just a little bit restrictive but not that. Hell lot better than a band aid. 485 00:29:51,240 --> 00:29:56,240 With Adam in the chair, Jamie prepares our three germaphobes guests. 486 00:29:56,240 --> 00:29:58,240 Welcome to the party. Thank you. 487 00:29:58,240 --> 00:30:08,240 So this is how this is gonna work. Adam has a cold and your job is not to get that cold. You still have to stay here, you can't just leave, but you don't want to catch his cold. 488 00:30:08,240 --> 00:30:11,240 Alright, sounds good. Gross. 489 00:30:12,240 --> 00:30:18,240 Carrie Grant and Tori will try their germaphobes best not to pick up Adam's nasal secretions. 490 00:30:18,240 --> 00:30:25,240 However, the control group, the remaining three guests, will have no idea Adam is even secreting. 491 00:30:25,240 --> 00:30:27,240 Hello, Pearl, nice to meet you. 492 00:30:27,240 --> 00:30:33,240 Adam just wiped his nose and now he's shaking hands. That stuff's getting everywhere. 493 00:30:33,240 --> 00:30:42,240 While Jamie tracks the contamination, Adam's rig will drip at exactly the rate a human nose runs, 60 milliliters an hour. 494 00:30:42,240 --> 00:30:44,240 Oh, we're gonna have a fun little party here. Are you guys ready? 495 00:30:44,240 --> 00:30:45,240 Yeah. 496 00:30:45,240 --> 00:30:52,240 I'm sorry. Got a little bit of a stuffy nose, but this should all be very cool. 497 00:30:54,240 --> 00:31:02,240 Remember, the goal is to find out if Adam will pass on his pseudo secretions to his guests through the normal activity of a party. 498 00:31:02,240 --> 00:31:03,240 Thank you very much. 499 00:31:03,240 --> 00:31:07,240 Thank you. Thanks for participating in my little science experiment here. 500 00:31:07,240 --> 00:31:08,240 Cheers, Fork. 501 00:31:08,240 --> 00:31:15,240 So we're getting some good contact here. We've got him handling the plates, the forks, those are being passed over. 502 00:31:15,240 --> 00:31:18,240 We're then lucky each one of those has been marked. 503 00:31:18,240 --> 00:31:30,240 Although our trio of germaphobes keep an eye on exactly what Adam's touching, the unprepared guests have no idea what's being passed around. 504 00:31:30,240 --> 00:31:36,240 Okay, it looks like as he's pouring, he's touching them on the shoulder, so each one of those is a mark. 505 00:31:36,240 --> 00:31:39,240 There ain't no party like a Mythbusters party. 506 00:31:39,240 --> 00:31:40,240 That's a good roll. 507 00:31:40,240 --> 00:31:44,240 And although the good times and the dice roll, 508 00:31:44,240 --> 00:31:45,240 I definitely lost. 509 00:31:45,240 --> 00:31:48,240 eventually the fun must come to an end. 510 00:31:48,240 --> 00:31:49,240 Thanks again. 511 00:31:49,240 --> 00:31:51,240 Ha ha ha ha. 512 00:31:51,240 --> 00:31:52,240 Tori. 513 00:31:52,240 --> 00:31:53,240 I'm celebrating you. 514 00:31:53,240 --> 00:31:56,240 Thank you so much for coming here. 515 00:31:56,240 --> 00:32:04,240 But of course our test subjects are still in the dark and the moment has come for the big snotty reveal. 516 00:32:04,240 --> 00:32:08,240 What was going on was that I had a mechanical runny nose. 517 00:32:08,240 --> 00:32:13,240 I had a little tube running down the side of my nose dripping a fluorescing fluid. 518 00:32:13,240 --> 00:32:19,240 The goal was to see how far my nasal secretions might travel if I had a cold and who might get those on them. 519 00:32:19,240 --> 00:32:23,240 To give you an idea about how much it spread on me alone, 520 00:32:23,240 --> 00:32:25,240 normally my skin would not fluoresce under black light. 521 00:32:25,240 --> 00:32:26,240 Are you ready? 522 00:32:26,240 --> 00:32:27,240 Oh. 523 00:32:27,240 --> 00:32:28,240 Oh. 524 00:32:28,240 --> 00:32:29,240 Oh. 525 00:32:29,240 --> 00:32:36,240 Adam may look like a radioactive clown, but has he spread his radioactive red snot? 526 00:32:36,240 --> 00:32:41,240 First off, the unknowing guest guinea pigs. 527 00:32:41,240 --> 00:32:44,240 Leah, let's see those hands hold them up into the light. 528 00:32:44,240 --> 00:32:45,240 Oh yeah. 529 00:32:45,240 --> 00:32:50,240 They all bear the telltale signs of contamination. 530 00:32:50,240 --> 00:32:53,240 But what about our germaphobe trio?
