"You're not to try any experiment you're about to at home." "You heard it, don't do it on this...." "Aha choo.... ...Adam and Jamie take on two common cold conundrums..." "Go get cleaned up." "First, they test their limits, finding out if you sneeze at 100 miles per hour..." "Whoa!" "That is nasty." "...And over 30 feet." "Oh, it's happening." "Then they investigate if someone else's runny nose..." "That's funny." "...Will eventually catch up to you." "Aah." "Meanwhile, Kari, Grant, and Tory..." "It put a big gash, but it didn't cut his head off." "...Put their necks on the line..." "Holy mackerel!" "Look at that tornado!" "...To find out if a tornado can turn glass into a guillotine." "All right, here we go in 3, 2, 1." "Tornado!" "Tornado!" "Who are the Mythbusters?" "Adam savage..." "Explosives are funny creatures." "...And Jamie Hyneman." "Well, there's your problem." "Between them, more than 30 years of special-effects experience." "Joining them... whoa!" "Whoo!" "...Kari Byron..." "Right tool for the job." "...Tory Belleci..." "We only have one shot at this." "...Grant Imahara." "That was a great result!" "They don't just tell the myths." "They put them to the test." "***" "so, what do you think?" "Are we ever gonna run out of myths?" "No way, dude." "We are still finding great material from the most common sources imaginable." "Like what?" "The common cold... specifically, the sneeze, which supposedly leaves your mouth at 100 miles an hour and can travel up to 30 feet, spreading your germs." "I think both of those are claims we could put to the test." "And sneezing's not the only thing you have to worry about." "I mean, if you've got a cold, you touch your face and you touch something else, and before you know it, you got nasal secretions all over the place." "Meaning you could supposedly catch a cold from someone without having any physical contact with them whatsoever." "Common-cold myths..." "let's do it." "Okay." "Ah-choo!" "That's two feverish fables to tackle." "First up, the physics of a sneeze." "Does snot really rocket at speeds of 100 miles per hour and spread disease over 30 feet?" "Let's start with the sneeze." "How do you want to tackle it?" "That one's pretty straightforward to me." "I mean, a sneeze is supposed to travel at 100 miles an hour." "Let's test it by firing up the high-speed camera and using a little math." "What about distance?" "Distance is a little tougher." "I mean, we're gonna have to be tracking what have to be freaking tiny droplets of liquid up to 30 feet away?" "I've got some ideas about that." "You worry about inducing a sneeze, and I'll worry about measuring it." "Fair enough." "All right." "According to public-safety announcements through the ages, the power of the sneeze is potent." "Remember, sneezes can travel at over 100 miles per hour and spread contagion over 30 feet." "But are those formidable figures really true?" "To find out, first, they'll clock the speed of a sneeze on a high-speed camera and then track its distance." "So, for that, Adam creates a sneeze shooting range." "Oh, hey." "Check it out." "Wow." "I think that's the biggest and fanciest gauge we've made." "Yep." "Well, 30 feet... supposed distance that a sneeze can travel." "Looks like it ought to be up to snuff." "Ha ha ha!" "And speaking of snuff, Adam's got just the stuff." "How are we gonna sneeze?" "Well, if you remember the "sneezing with your eyes open" episode, it's actually caused us some real difficulty." "However, we have found a foolproof method for this episode, and that is tobacco snuff." "The snuff will work to irritate the mucosa at the back of Adam's nose, which will bring on a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth..." "Ah-choo!" "...Or, a sneeze." "Ah." "Little snuff for science." "There we go." "And another one...... for good measure." "Whoo!" "Whoa, that is nasty!" "Nasty and captured by the high-speed camera at a stomach-churning 3,000 frames per second." "And that stuff's made to snort, huh?" " It is." "I have no idea why anyone would do it recreationally." "Well, let's see how fast it went." "Okay." "By counting the number of frames it takes a snot droplet to travel 1 foot, they work out the speed of Adam's sneeze." "Oh, wow." "You know what?" "Watching it go backwards is really pretty sickening." "Okay." "51 feet per second times .68 equals... 35 miles per hour." "That's not 100 miles an hour." "That's nowhere close to 100 miles an hour." "I should have a go." "All right." "Watch for the 'stache." "35 miles per hour is certainly not the mythical 100, so Jamie steps up." "Once again, the snuff squeezes a sneeze, but will it be faster?" "Oh, look at that 'stache!" "Like Indiana farmland in the breeze, isn't it?" "Getting quite poetic here, aren't we?" "The subject matter." "57 feet per second..." "Times .68 equals... 39 miles per hour." "Still nowhere near 100, huh?" "Nope." "You busted out." "You beat me in the speed department, but it's nowhere close to the myth." "Well, apparently, I sneeze at 35 miles per hour, and the Hyneman sneezes at 39 miles per hour." "Neither of those is remotely close to 100 miles an hour, so that myth, I think, is pretty busted." "Now we're on to distance." "Does a sneeze really travel 30 feet?" "And I think Mr. Hyneman already has some ideas about how to track that." "When Adam sneezes, we need to see how far the stuff that comes out of his nose travels, and so, to do that, I'm gonna add this cherry-flavored red kids drink mix to the snuff that he inhales," "and when he sneezes, hopefully, we'll see little red dots on this lovely strip of white paper." "This time, Adam's sneeze should leave a telltale trail of cherry-colored tracks." "Oh!" "Ugh!" "Oh, it's irritating and sweet and fruity!" "Oh, it's happening." "Gesundheit." "And now to check the distance." "I don't see any red flecks." "Unfortunately," "Adam's fruity sneeze hasn't left a mark." "But, as always, there's a solution." "We have a new plan." "The new plan is, rather than snort any more colored things," "I'm going to go back to the snuff, but just before I sneeze," "I'm gonna spray some uncut food dye into my mouth." "Yeah." "That ought to show up." "Adam takes a snort of snuff and a swig of food coloring." "God, it looks like a murder scene here." "Ah." "Ugh!" "That time around, the sneeze went, quite literally, with flying colors." "Ah." "We got one out here at 17 feet." "That's not bad." "No." "You're halfway there - over halfway." "But I think that's about it." "Think that's about it?" "Yeah." "I think I need to then try again." "We're making modern art, as well as some science." "Adam can't leave it at 17 feet." "He's going for a second distance attempt, but this time in a less-gory blue." "Nice!" "You're getting a good spread But you need to work on your distance." "Okay, coach." "Well, I'm clearly hitting a hard line at 17 feet." "You want to see if you can do better?" "With Adam not even reaching 60% of the mythical distance," "Jamie's next up for the sneeze gallery, and he'll be sneezing in green." "I think that's all I got." "All right." "Why don't you go get cleaned up?" "Unfortunately, Captain Greenbeard's sneeze also didn't go the distance, and you can't help thinking it has something to do with his mustache." "Nope." "Looks like Jamie maxed out right here at 13 feet." "I got 13 feet of travel out of my sneeze, and Adam got 17 feet." "It's not 30, but it's an awful long ways." "So where does that leave the mythical sneeze?" "The myth says that a sneeze can travel up to 30 feet, and our sneezes didn't get anywhere close to that." "They got to 17 feet and stopped." "It's still pretty far, but I guess that means..." "It's busted." "Yeah." "Next up..." "I guess you can have a worse shot." "...Kari, Grant, and Tory get a head start on their decapitation myth." "Next up, a myth that could be a storm in a teacup." "Our next myth is about tornadoes, and it comes directly from the fan site." " What do we got?" " All right." "So, the myth is that, during a tornado, glass can get sucked out of a window and travel so fast that, if you're in the wrong place at the wrong time... fching!" "... you get your head cut clean off." "Like a flying guillotine?" "Exactly." "This is perfect." "Fast-flying glass?" "Decapitation?" "This sounds right up our alley." "Tornado alley, that is." "Where are these frickin' crickets?" "When the tornado alert goes out, the safest place to take shelter is inside a storm cellar." "With winds over 200 miles an hour, everyday items can be quickly transformed into lethal projectiles." "But could glass whipped up by these winds really turn into a guillotine?" "Okay." "So, what's the plan?" "Well, I think, first, we have to create a human-analog neck." "All right." "Well, why don't we get a pig spine, we'll keep the muscle on it, and then we'll wrap it with its own skin?" "It'll be just like a human neck." "And then we can just take pieces of glass and start throwing them at it." " I guess we got to start somewhere." " Cool." "Now, when you think of tornadoes, you probably think of houses flying through the air," "Kansas farm girls and their dogs blowing away." "Now, that would be like a force-4 tornado... up to 200-mile-an-hour winds." "But I think you'd be surprised to know how slow tornado winds can actually be." "A force-zero tornado has winds at like 40 miles an hour." "Now, that could be comparable to what we could fling our glass at." "Now, in order to test this myth accurately, we need a very human-like neck, because we're not gonna be able to use a real human." "What I have here is an mri of a human neck." "As you can see, there's skin, trachea, vertebrae, muscles surrounding all of it, and more skin." "Now, normally, if we were gonna make a human neck, we would just take a pig spine and cover it in ballistics gel." "This time, we're gonna make it way more human-like." "She's gonna love this." "Vimwers, and, eh, pigs of a nervous disposition may want to look away now." "Oh, seriously?" "This is perfect." "Look at this." "It's an entire pig's vertebrae, with the skin and muscles still intact." "I mean, its practically a neck already." "True enough, but it does need a little surgery." "Tory first removes the ribs..." "You're gonna clean the saw when you're done, right?" "...Then the lumbar vertebrae." "Yeah, that's better." "He next trims away the fat." "That's the juice." " Here, Kari." " Aah!" "Saved that piece for you." "But he does keep the length." "After all, a longer neck makes for a bigger target." "Once Kari's all sown up and an 8-pound human-like head is crowned," "Neckman is good to go." "So, what's the plan?" "So, our plan is pretty simple." "We're gonna take turns flinging panes of glass at Neckman." "And this is the glass." "It measures 12 inches by 12 inches by 1/8-inch thick." "But most importantly, it conforms to the residential building code of houses that are actually in tornado alley." "Given how sharp this edge is," "I think there's a very real possibility that we could sever a neck at throwing speed." "Aah!" "Provided, of course, that they hit it..." "Starting with Kari." "Here we go." " That was not anywhere close to the neck!" " Ho!" "Holy crap!" "With Kari's backhand misfiring, she switches stance But gets the same result." "How much glass do we have?" "Are we gonna need to order some more glass?" "The problem here is not just accuracy." "It's also speed." "Maxing out at a disappointing 30 miles an hour means Kari's not even reaching a force-zero tornado." "Next to step up to the plate glass, it's Grant." "All right, everybody... take cover!" "Grant's throwing!" "Aah!" "I guess you can have a worse shot." "Ooh-hoo!" "You guys okay?" "Everybody okay?" "Although the accuracy was abysmal, the speed, at 50 miles an hour, was solid." "Now if he can just get focused." "Whoa!" "Nice shot." "Yeah, nice shot." "Still, not enough to cut the head off." "It may indeed have been a giant pain in the neck, but a decapitation at 50 miles an hour it wasn't." "So last up to put his neck on the line is Tory." "Now, I like Kari and Grant's technique." "However, my approach - I'm gonna throw out accuracy..." "Pbht!" "Pssh!" "...And I'm gonna focus on speed." "I'm gonna throw this piece of glass as fast as I can throw it." "And if it hits the neck, it hits the neck." "Hopefully, if I get it going fast enough and I do hit that neck, we'll see a decapitation." "Foregoing accuracy for speed may seem foolhardy, but on take one..." "Here we go." " Ohh!" " Beautiful shot." " Nice!" " Good shot." " That was a direct shot." " That was great." "Tory nails the perfect shot, but the high-speed reveals a very imperfect result." "Look at that." "You got 68 miles an hour." "And it hit right on the neck." "But look at it... the glass just completely shatters." "I mean, it was going fast, and we hit it, but it didn't cut the head off." "The force-1 tornado pane hits dead center, but it's the glass that gives way and not the neck, meaning, with this glass, decapitation is impossible." "As you can see from all the carnage around me, we threw a lot of glass at this creepy dude here, but we did not achieve a decapitation." "Now, I think this is for a few reasons." "First of all, after looking at the high-speed, doing a couple of calculations, it looks like we were throwing the glass at the bottom of the tornado scale." "Just not fast enough." "Secondly, when the glass actually was hitting the guy, it was shattering too easily." "So, we're gonna need thicker, stronger glass, and we're gonna need to throw it a lot faster, which means we got to build a machine." "Coming up next..." "That's disgusting." "...Adam and Jamie are on the nose with a snot-spreading saga." "Stand back, because it's time for some mucus mayhem." "Nasal secretions." "The myth that someone who's got a cold is spreading their secretions everywhere, far and wide, and that they're impossible to avoid." "Well, the first thing we need to do is to figure out how to make nasal secretions we can track." "And we need a situation we can track them in." "Okay." "Well, I guess I need to go talk to an expert about nasal secretions." "I guess you do." "According to the myth, just by being near someone with a runny nose, you'll end up contaminated by their snotty secretions." "But can a running nose really scatter snot on more than just its owner?" "To test that, they'll need a group of party people, a nose-running rig, and a nasal-secretion substitute." "But before they start spreading the snot," "Jamie needs to know just how much a runny nose really runs." "Come in." "Hello, doctor." "Hi." "Nice to meet you." "You too." "Luckily, Dr. Andrea Yeung is just the person to ask." "So, what would you consider a normal rate of flow when you have a cold?" "If you think about your sinuses, just in general, in terms of the amount of fluid that you could potentially hold, we would expect that that volume would be somewhere on the order of about 60cc, or 60 milliliters, to come out in about an hour." "And how exactly does that 60 mils transfer its viral payload?" "Secretions kind of get passed to the hand." "That hand then goes into your mouth, into your nose, or into your conjunctiva or sort of the lining of the eyes, and then again gets brought into your system." "It's exactly that spread that the Mythbusters will test." "And now Jamie knows how a nose runs." "Now that I have my flow rate," "I can build a nasal-drip rig to simulate a runny nose." "It has to be compact, it has to be very accurate, and I have to be able to conceal it." "And there we are." "It's doing it by itself." "Just a syringe and some tubing later, and Jamie has a dribbling drip rig." "Now all he needs is a willing volunteer to give it a dry run." "You look totally like you've got a cold just from your mannerisms." "You know, like, "uh, I don't feel good."" "It feels like I've got a cold." "It's just as annoying." "Makes me feel like I want to stand apart from you so I don't catch it." "Well, you don't want to catch the red dye." "That's what you don't want." "That's funny." "We're about to investigate how far and wide my nasal secretions may travel if I had a cold." "Now, I don't have a cold." "We're going to achieve my cold by Jamie giving me a mechanical cold, which is a drip rig that will be strapped to my face and slowly dripping a fluorescing fluid." "Jamie has carefully selected a nontoxic fluorescent dye that's invisible to the naked eye but will glow orange under a black light." "To ensure there is no cross-contamination, he first checks the table." "Okay." "The space is clean, and I don't see any marks on you." "I think we're good to go." "Then Jamie starts the nasal drip and leaves Adam to some modeling." "I'm ready to start constructing." "I'll start the timer... now." "Good luck." "Thanks." "Remember, they're testing to see if Adam's pseudo-snot will spread far and wide." "And after an hour of building, gluing, and wiping, 60 milliliters of fluid has dripped through the nose rig." "Okay, so, time's up." "We got to see how far your nasal secretions went." "Excellent!" "All right, let's do it." "Dun dun dun!" "Oh, my gosh." "Look at that." "That is... wait." "Look at my face." "That's disgusting!" "Am I, like, just covered with it?" "You are." "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." "Well, we set out to construct an experiment whereby we could track my nasal secretions, and I have to say, I think we've done stunningly." "They seem to have gotten absolutely everywhere." "Everything on this table has a little touch of orange on it." "That's the name of my cover band... touch of orange." "Obviously, Adam's pseudo-snot got everywhere, which is amazing, given that it was coming out a tiny droplet at a time." "But what does this mean as far as transmitting a cold virus or a flu?" "Well, to find that out, we've got to introduce people, and so that's what we're gonna do next." "Next, the Mythbusters will track the spread of snot by partying in the name of science." "Don't try anything you see on this show at home." "We're what you call experts." "In a perfect storm of circumstance, could a tornado turn glass into a guillotine?" "Well, not so far." "Okay." "So we're struggling with decapitation, big-time." "Yeah." "I mean, throwing a piece of glass accurately, even at low speeds, is very difficult, and the pieces of glass keep shattering." "And it's only gonna get harder as we ramp up the speed... something we actually have to do." "All right." "Well, what if try this?" "What if take our head and neck, put it on the runway, and then we attach a sheet of glass to a vehicle horizontally, drive at the neck, and then release the glass before it hits the neck." "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." "I love it!" "Let's do it!" "So, at the Alameda runway, the team's foregoing the throwing to tackle this myth head-on." "You guys ready to see if we can make a tornado?" "Let's do it." "But how will a car going at 80 miles per hour represent a 300-mile-an-hour tornado?" "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..." "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." "I call that extreme tornado speed." "Grant's right, and it's over to Kari to explain why." "Tory's 450 gram pane of glass flung at 70 miles an hour had a kinetic energy of around 220 joules." "If that glass had been traveling at an f5 tornado speed of 300 miles an hour, it would have had the energy of over 4,000 joules." "Now, because the truck can only drive 80 miles an hour, to get a 4,000-joule hit, you need a heavier piece of glass." "So, how heavy?" "6 1/2 kilograms." "But will that cause a decapitation?" "That's one big piece of tornado alley code glass, and to put it to work," "Tory's built a rig that looks just as lethal as it is." "So, this is the super tornado decapitation rig." "So I built this steel structure That we've attached to the truck." "On the end of it is a piece of glass being held oh, so gently by these foam blocks." "When we hit the neck, the styrofoam will break, and the glass will act as if it's flying through the air." "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 and confirming this myth." "With Neckman's neck on the line..." "Holy mackerel!" "Look at that tornado!" "...It's all systems go." "Okay, Tory Belleci." "Are you ready?" "I am in position and ready to go." " You ready?" " Ready." "Okay." "This is Neckman versus the large piece of glass in 3, 2, 1." "Not wanting the glass to slip loose," "Tory gently accelerates up to 80 miles an hour." "Here comes..." "Tory:" "Here comes the tornado!" "That's what I was gonna say!" "Now is the time I feel compelled to yell "duck!"" "Ohh!" "Whoa-ho-ho!" "Wow." "That was almost no hesitation whatsoever." "That was gruesome." "I mean, there was no resistance." "The head just came off." "All right." "Let's check it out." "That was incredible." "All I heard was the "thkk," and I looked back, and I saw his head on the ground." "But, hey, the rig worked!" "Yeah." "It's mission accomplished... a nasty decapitation on the very first run as the glass cuts clean through." "But in a "mythbusters" first, the next step is to ramp the results down." "Now, I can't say that I'm surprised by this because that amount of energy contained in that glass traveling that fast Would be like a super tornado... an incredible tornado, a 300-mile-per-hour-plus wind speed tornado." "And the thing is, you don't have those kinds of tornados every day." "So what we're gonna do next is actually go at a slower speed, try the same experiment, this time simulating a more average tornado and see what we get." "So they're going to re-run this test at 40 miles an hour." "And thanks to the marvel of math, we know that the heavy glass going at 40 has the same energy as its smaller counterpart traveling at 150 miles an hour... a high force-2 tornado." "But will that be high enough?" "To find out, Neckman's cousin, collar boy, gets his moment in the sun." "Okay." "This is Neckman versus the big piece of glass at 40 miles per hour." "Take it away." "Tornado!" "Tornado!" "Yep, look out collar boy." "There's a storm a-comin'." "Whoa!" "What was that?" "Wow!" "We got a trail of destruction." "We got decapitation, and the glass broke away." "At first glance, it seems like we've reached myth confirmed as head and neck part company." "But the high-speed tells a different story." "It seems that the hair-trigger on the glass didn't work cleanly, and that means that some of the car's own momentum may have affected the outcome." "For this team of perfectionists, it's just not good enough." "We're really bothered by the fact that the glass is not totally dislodging." "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." "So the next obvious mythbustery step... well, we're gonna go build a robot in the shop." "Yep." "They're following that old "mythbusters" mantra... if in doubt, build a robot." "Tornado!" "If someone nearby has a runny nose, can they spread their snot to you just by being close?" "To find out, the Mythbusters are throwing a party." "Soon, I will have six guests, or, as I like to call them, test subjects, having a party with me under test conditions." "These conditions are three of my guests are gonna behave as germaphobes, three of my guests have no idea what's happening." "I will be spreading my nasal secretions far and wide while performing a series of normal party-like tasks... 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." "Now, if you'll excuse me, I need to get into makeup." "So as not to reveal what's being tested to our guest Guinea pigs, special-effects artist Danny gives Adam a nose job." "Oh, it's just a little bit restrictive but not bad." "Hell of a lot better than the band-aid." "With Adam in the chair," "Jamie prepares our three germaphobe guests." " Welcome to the party." " Thank you." "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." " All right." "Sounds good." " Gross." "Kari, Grant, and Tory will try their germaphobe best not to pick up Adam's nasal secretions." "However, the control group, the remaining 3 guests, will have no idea Adam is even secreting." "Hello." "Pearl." "Pearl, nice to meet you." "Adam just wiped his nose, and now he's shaking hands." "That stuff's getting everywhere." "While Jamie tracks the contamination," "Adam's rig will drip at exactly the rate a human nose runs... 60 milliliters an hour." "Oh, we're gonna have a fun little party here." " Are you guys ready?" " Oh, yeah!" "I'm sorry." "I've...... got a little... little bit of a stuffy nose." "But this should all be very cool." "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." "Thank you very much." "Thank you." "Thanks for participating in my little science experiment here." "You're a true sport." "So, we're getting some good contact here." "We've got him handling the plates, the forks." "Those are being passed over." " Here you are, sir." " Thank you." "With any luck, each one of those has been marked." "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." "Okay." "It looks like, as he's pouring, he's touching them on the shoulder, so each one of those is a mark." "There ain't no party like a "mythbusters" party." "Tory!" "That's a good roll." "And although the good times, and the dice, roll..." "Ah, I guess we lost." "...Eventually, the fun must come to an end." "Thanks again, Tory." "Good celebrating with you." "Thank you so much for coming." "Thank you." "But, of course, our test subjects are still in the dark, and the moment has come for the big snotty reveal." "What was going on was that I had a mechanical runny nose." "I had a little tube running down the side of my nose, dripping a fluorescing fluid." "The goal was to see how far my nasal secretions might travel if I had a cold and who might get those on them." "To give you an idea about how much it spread on me alone, normally, my skin would not fluoresce under black light." "Are you ready?" "Adam may look like a radioactive clown, but has he spread his radioactive red snot?" "Aah." "First off, the unknowing guest Guinea pigs." "Lea, let's see those hands." "Hold them up into the light." "Oh, yeah." "They all bear the telltale signs of contamination." "But what about our germaphobe trio?" "Despite their best efforts," "Grant and Tory couldn't escape the neon." "Grant, let's see those hands." "I couldn't avoid shaking your hand." "Tory?" "Oh, Tory." "You got... you got it on your face here." "Did we sneak off somewhere?" "Tory has even ended up with snot on his face." "Kari, however, is a different story." "I have to confess, I'm actually a germaphobe, so this was not too hard for me." "And I am not surprised I did this well." "Nice!" "Wow." "Incredible." "So, how many of us got colds?" "I'd say five out of the six of you have been legitimately exposed with only a 30-minute dinner party." "And one typhoid Mary." "So, even though I knew Adam had a fake cold," "I was still kind of grossed out by the idea, so I kind of employed all of my usual techniques not to get sick." "I didn't touch anything or anywhere that he touched." "When he handed me something, I wiped it off with my napkin." "Right at the very end of dinner, as we were saying our goodbyes," "Adam stuck out his hand, and I had to shake it." "And you know what?" "If someone sticks out their hand, you can't avoid shaking it." "That is where he got me." "With five out of six guests infected and a dinner table that's more neon than not, where does this leave the myth?" "Look around me." "Look at how far and wide my secretions have spread to everywhere on this table." "Next time you think you've got an innocuous runny nose, think again." "Think again, indeed." "But that isn't the end of this snot-spreading saga." "If you want to see more, log on to discovery." "Com/mythbusters." "Check it out." "When a tornado hits, chances are it's gonna do a lot more than ruffle your nerves." "Now, to simulate a tornado, we first started by throwing panes of glass by hand with little success of decapitation." "Then we moved on to a giant piece of glass strapped to the side of a car and drove at high speeds into a neck, and we got a decapitation, but we think the momentum of the car added too much to the kinetic energy," "really loading the deck on this myth." "So now we want some realistic circumstances." "We want a small piece of glass flying at moderate tornado speeds to see if even that will get us a decapitation." "So, how exactly are we going to accelerate a piece of glass very quickly?" "Well, the first step is to take a bunch of these caster wheels and flip them upside down like this..." "So that we have a low-friction surface to slide our glass on." "It's like a little conveyor belt of potentially deadly glass." "At the end of this line, these two tires go on an axle, which is connected to an electric motor." "Yeah, that ought to do it." "That's gonna spin at a really high speed." "Now, a second set of wheels is going to go on top, and that's gonna form a sandwich." "You're gonna love this." "So that, when the sheet of glass comes in, the wheels are gonna catch it, and... shwo!" " Send it out at tornado speed." "Now, we're hoping that this machine is going to actually help us with our speed and accuracy, but like most of Grant's truly intimidating-looking rigs, we don't know what it's gonna do until we do a few tests." "So we're gonna throw some glass in, see exactly how fast it's going, and make sure it's all going in the right place." "And that glass is going to be twice as thick and twice as heavy as the glass the guys first threw." "Go, go, go!" "Yeah!" "Ha ha!" "Hoo." "All right, let's see how fast that one went." "It was scary!" "I know a test goes well when I'm terrified." "The machine worked like a charm, flinging the window wannabe at 70 miles per hour." "And that means it's Neckman's curtain call." "Chin up, buddy." "It's very important that you keep your chin up for this one." "After several tests with our "pane in the neck" rig, we think we have it dialed in." "We have 70 miles an hour and a perfectly flat flight pattern, so now we're gonna bring in the neck and see if we have a decapitation." "All right, this is tornado decapitation, 1/4-inch sheet of glass." "Neckman is in position." "Motor is full power." "We are going for tornado speed." "I'm ready for the "necks" test." "Okay." "Tornado speed in 3, 2, 1!" "Go, go, go!" "Wait, wait, wait, wait, wait." "A direct hit, and Neckman's head's gone awol." "But it's not all good news." "I know what you're thinking..." ""it worked!" "You decapitated him with a piece of glass!"" "Actually we looked at the high-speed and what really happened was the glass hit him right here in the mouth, and it just ripped his head off the neck." "There was no cutting through skin, no cutting through muscle, no cutting through bone." "This was not a decapitation." "So we need to get a new head, reset, and try it again." "A new head?" "How about this one?" "Aah." "Aah." "Aah." "Neckman in position." "You guys ready?" " Ready." " All right, fire it up." "Go, go, go!" "This time, Neckman's painfully down for the count." "But a decapitation this ain't." "So far, the robot is 0 for 2... a record that then takes a turn for the worse with near misses..." "That was so fast, I have no idea what just happened." "...And not so near misses." "Man." "I wonder if it's possible to decapitate a guy with glass." "I don't know." "With the final Neckman in the firing line, it really is now or never." "You ready to get your head cut off?" " You ready?" " Ready." "All right, fire it up." "Okay." "Here we go. 3, 2, 1." "Go, go, go!" "I think we've got decapitation!" "That is unquestionable." "We have a piece of glass flying at a low tornado speed in the air, on its own merit, and decapitates our head completely off and cleanly." "That shows us right there confirmed, confirmed, confirmed." "Yep." "This all goes to show the danger of flying debris during a tornado." "For safety, taking shelter in a storm cellar really is a no-brainer." "Adam and Jamie have proved a runny nose will eventually catch up to you." "Where does that leave us?" "Well, we wondered, suppose the person who is spreading the germs is acting more responsibly?" "Suppose they're trying to keep others from being infected?" "That's what we're gonna test next." "We've set up this whole space again, totally clean." "I haven't touched anything here." "I will have the same drip rig going on, dripping at the same rate, except I'm going to be trying to keep my germs from spreading to any parts of this table and any of my guests." "Let's see how I do." "So, the Mythbusters will repeat the nasal-secretions test..." "Pow!" " Hello." " Hello." "Hello." "Good to see you." "...With two vital differences." "Adam will do everything he can not to spread his pseudo-snot, and we've got a new set of blissfully unaware test subjects." "But I've got to warn you..." "I've got a little bit of a cold, so let's do an elbow greet." "How are you?" "How are you?" "But will modifying his behavior decrease the chances of contamination?" "He's not shaking hands." "He's bumping elbows." "Despite the fact that his nose is still dripping at 60 mils per hour," "Adam is doing all he can to limit his hand-to-hand contact with his guests." "And, Tory, if you would take this and hand out a sheet to everybody..." "Dana, if you would pass these pens to your... pass these pens to your right and make sure everyone gets a pen." " We're gonna play a game called dictionary." " Oh!" "But as well as avoiding direct contact with his guests," "Adam's also avoiding indirect contact by enlisting their help." "Dana, will you hand out the glasses for me, please?" "At this point, it looks like he's doing pretty well because the only thing that's actually been passed around, person-to-person, has been the paper notes." "The glasses, the bottle, even meeting everybody in the beginning, didn't involve any kind of contact at all." "And once again, the 30 minutes seems to fly by until it's time to bring in the bouncer." "All right, then." "So, everybody's had some cake, some champagne, you've played a couple of games." "Lovely party!" "Time to call it quits." "Jamie says it's time to go, it's time to go." "Wow!" "What a buzzkill." "Right?" "And with that, the test is over." "But has Adam kept his snot to himself?" "Bye-bye." "Bye." "Okay." "Let's see your hands." "You're clean." "You're clean." "Well, the result is spelled out in no neon light." "Clean." "Clean." "Good job, Adam." "In stark contrast to the previous test, amazingly, Adam has not infected a single guest." "I got to say, that was totally amazing." "Just by a simple change of technique, you can prevent everyone at the party from getting sick." "Let's recap." "The myth that if you are sick, your nasal secretions will go everywhere." "Confirmed." "And the ability as an innocent bystander for one to avoid those secretions." "Not impossible but very difficult." "So, what have we concluded is the best way to prevent the spread?" "Well, if you're sick, you need to take some personal responsibility." "Absolutely right." "This has been a public-service announcement from Jamie and Adam at "Mythbusters.""
