"Please don't try anything that you're about to see us do at home." "Ever!" "NARRATOR:" "On this "Way too drunk to drive" episode," "Adam and Jamie get sloshed for science." "Whoo!" "I usually don't let people do that." "NARRATOR:" "What is the best way to get sober in a hurry?" "Oh!" "NARRATOR:" "And is the myth of beer goggles fact or fantasy?" "She's pretty darn cute." "NARRATOR:" "Then, Kari, Grant, and Tory rebuild an ancient weapon of mass destruction." "Hwacha!" "NARRATOR:" "They start with one fire arrow, then try launching 200 to see if the hwacha lives up to its legend." "Who are the Mythbusters?" "ADAM:" "[ Laughs ]" "NARRATOR:" "Adam Savage..." "[ Laughing maniacally ]" "NARRATOR:" "...and Jamie Hyneman." "Feel like I'm ready to go out clubbing." "NARRATOR:" "Between them, more than 30 years of special-effects experience." "Freedom!" "NARRATOR:" "Joining them -- Grant Imahara..." "[ Laughs ] You suck." "NARRATOR:" "...Tory Belleci..." "Put your back into it." "NARRATOR:" "...And Kari Byron." "High explosives and electricity." "Whoo!" "NARRATOR:" "They don't just tell the myths... they put them to the test." "Let's wet our whistles with the myth of beer goggles." "I'm feeling a little left out here." "And I'm glad." "What's going on?" "Beer goggles." "Beer goggles?" "Beer goggles!" "It's been out there waiting for us the whole time, and for some reason, we haven't tested it -- the idea that alcohol has this magical property that will make people around you more attractive the more you drink." "Actually, I feel like I've been testing this for over a decade." "Yes!" "But that's anecdotally." "We are going to test it scientifically." "Great." "More drinking on the job." "NARRATOR:" "Jamie knows that eventually this will turn ugly." "They'll have to lose their inhibitions, and maybe their lunch, to test the truth of beer goggles." "This seems to be a really subjective thing." "We need to be objective if we're gonna be scientific." "How are we gonna do that?" "Large sample size?" "That's exactly what I'm thinking." "And I'm thinking that we rate photos." "Specifically, we get a bunch of photos -- us of women, you of men." "We review a whole bunch and rate them when we're sober." "And then we get drunk and re-rate those photos." "And see if there's a difference." "Exactly." "NARRATOR:" "But before we raise our glasses, let's meet the newest member of the team, with a vital role to play." "This is our new SMART Board." "Not only is it a really big, beautiful interface, but it's also interactive." "Let me show you a couple tricks." "Watch this." "[ Laughs ]" "How about that, huh?" "Huh?" "You like that?" "It gets better." "Check it out." "Not only can I even do that," "I can also diagram what's gonna happen in real time." "I'm not gonna go too much farther showing the tricks this thing can do, 'cause we're about to use it a whole bunch in this very episode." "NARRATOR:" "The board's first job is to help Adam, still sober, rate the looks of 30 women from 1 to 10." "Here we go." "NARRATOR:" "He's got just five seconds to score each photo." "He can see the time tick down on the left of the screen." "ADAM:" "I got to say, the exercise of giving a quick rating, it doesn't feel great." "It's kind of an awful thing to have to do." "[ Chuckles ]" "Aah!" "Like, I found myself resisting giving a 1 or a 2, but..." "NARRATOR:" "Yeah?" "But?" "I got a 96!" "[ Laughs ]" "So the total possible score is potentially 300." "Out of that, I gave a 96." "The question from here on in will be, as I drink, will my overall score go up?" "NARRATOR:" "Now it's Kari's turn to rate the chaps." "KARI:" "Quite honestly, there are no supermodels on here." "Oh, God." "Do I rate you on your hair?" "Mm!" "NARRATOR:" "Kari's either much more generous or less discriminating than Adam." "[ Ding!" "]" "Okay." "Total score -- 154." "NARRATOR:" "But she does know what pushes her buttons." "I noticed I was rating higher on men that looked confident." "If they looked sort of squirrelly and really apprehensive about the whole thing," "I definitely gave them a lower score." "NARRATOR:" "Now for a man who's anything but squirrelly." "Your turn." "Okay." "JAMIE:" "I'm about to look at a bunch of pictures of women, apparently, and try to objectify them." "[ Laughs ]" "NARRATOR:" "Jamie's got a point." "Snap decisions based on looks alone are shallow and shameful." "But hey, it's all in the name of social science." "JAMIE:" "It's set up so that it's sort of a gut reaction." "I don't know how consistent it's gonna be, but that's where the averaging becomes important." "'Cause you've got some kind of a number that should show a trend." "NARRATOR:" "And Jamie's trendy number?" "Higher than Adam's, but lower than Kari's." "JAMIE:" "So I got a 116." "Whatever that means." "NARRATOR:" "Well, it means nothing till they've done this twice more -- first slightly inebriated and then stumbling, dribbling drunk." "Hello, Ginger." "Hi, Adam." "How you doing?" "Good." "How about three beers?" "NARRATOR:" "The aim here is to get buzzed." "For the boys, that means two or three quick brewskies." "For Kari, maybe one less." "What's red and smells like blue -- blue paint?" "What?" "Red paint." "[ Both laughing ]" "She got Jamie giggling." "NARRATOR:" "Ginger keeps the suds coming." "[ Burps ]" "NARRATOR:" "And they're ready to test if they're officially buzzed." "ADAM:" "Let's do a Breathalyzer." "Let's get some science going." "[ Laughs ] It sounds like fun." "[ Exhales deeply ]" ".06." "NARRATOR:" "Over to Kari, who proves she's too drunk to drive." "ADAM: .08." "She's at the legal limit." "[ Exhales deeply ]" "NARRATOR:" "Then Jamie blows the same number as Adam." "ADAM: .06." "NARRATOR:" "But will their slightly pickled perceptions affect the way they judge the opposite sex?" "How am I gonna do when I'm buzzed?" "I don't think it will be a whole lot different than sober." "NARRATOR:" "Adam's not so sure, and he's the first to try it." "I'm at a .06." "You guys, don't cheat." "Don't look over here." "You got it?" "KARI:" "No problem." "Okay. "Adam Buzzed."" "Here we... go." "NARRATOR:" "This time around, they've got 30 new faces, judged by others to be exactly as attractive as the first batch." "ADAM:" "I can already feel my ratings being higher." "[ Laughs ]" "I found it much easier to rate them buzzed than sober." "I started to feel bad for the 1 s and 2s while sober." "Buzzed, didn't care at all." "1!" "1!" "2!" "You're out!" "NARRATOR:" "Harsh words." "But his tally supports the myth." "He is finding these faces more attractive." "My buzzed score overall was 121." "NARRATOR:" "That's 25 more than his sober test." "So, on average, each girl rates almost a full point extra." "Now for Kari, who was far kinder than the boys first time 'round." "KARI:" "I think I get a little giddy after a few drinks, so I think I might be pretty generous after I've had a beer or two." "NARRATOR:" "Or three." "Kari also has 30 new faces to rate." "Again, all average Joes." "That is some fabulous hair." "NARRATOR:" "But the beer-goggle effect seems to be working in reverse." "KARI:" "Is this an uglier group of people?" "I wouldn't give most of those guys change if I passed them on the street." "NARRATOR:" "Just two hours ago, sober," "Kari rated a similar group at 154." "Now that she's loosened up..." "KARI:" "My buzzed score was 89." "I might be a mean drunk." "I'm not sure if I was charity rating before, 'cause I felt kind of bad for some of the uglier people." "But there was absolutely no talent in this group." "None." "NARRATOR:" "So Jamie steps up to rate the new babes." "And remember, he predicted no change whatsoever." "JAMIE:" "Here we go. "Jamie Buzzed."" "My perceptions of what made them attractive or not attractive were pretty much the same as they were the last time, as far as I know." "I mean, nice complexion, regular features, signs of health -- things like that." "NARRATOR:" "But after three beers," "Jamie's brain is lightly sautÃ©ed." "It all comes down to one number." "Okay." "I'm done." "My buzzed score was 105." "NARRATOR:" "His sober score was 116." "But we're yet to test anyone cross-eyed drunk." "And when we do, the figures, I promise, will surprise you." "I feel like I've met her." "All right, you guys." "This next myth is gonna be insane." "What is it?" "That's it -- the hwacha." "lt's an ancient Korean weapon." "Oh." "If there's a picture of it, that means it's not a myth." "lt exists." "GRANT:" "Well, we know it exists." "What we're gonna test is the legend of the hwacha, whether or not it could do what they said it could do." "Apparently, they could fire 200 arrows all at once going 500 yards and all of the arrows explode on impact." "Okay, well, to begin with, any weapon in that era wouldn't have had the benefit of modern explosives or propellants." "It was likely based entirely on black powder." "So first, we need to find out if black powder can actually propel one of those arrows 500 yards." "Right, and then we need to see if we can get these rockets to explode on impact." "And finally, we need to see if we can launch 200 arrows simultaneously without them all crashing into each other or exploding on the stand." "NARRATOR:" "It's a massive myth to unravel, with three key parts." "One, can a fire arrow actually travel 500 yards?" "Two, can it be rigged to explode on impact?" "[ Gasps ]" "NARRATOR:" "And three, can you really set off 200 at once?" "So let's start up at the pointy end." "What I'm gonna do now is I'm gonna build one of these arrows from the materials that the ancient Koreans would have used." "I have some bamboo," "I have some feathers for my fletching and, finally, a piece of steel to make my arrowheads out of." "NARRATOR:" "Tory proves himself a first-class fletcher and a pretty fair blacksmith." "All right." "So my arrow's done." "Now it's time to see how it flies." "Hwacha!" "Pretty dang good." "NARRATOR:" "That's one down, 199 to go." "Tory leaves the hard work to Kari, as he and Grant skip town to visit Zambelli Fireworks in Pennsylvania." "TORY:" "We're lost, aren't we?" "NARRATOR:" "The rationale behind the road trip is that the fire arrows work just like skyrockets." "TORY:" "Now, if we happen to have some fun while we're here, that's purely coincidental." "NARRATOR:" "Just like fireworks, the hwacha rockets were charged with black powder." "Ours have to travel 500 yards strapped to a 4 1/2-foot arrow." "Grant and Tory are determined to roll their own, and Bill is here to help them." "Well, let's see." "What's one of these weigh?" "Well, about 4 ounces." "Every 12 ounces the shell weighs, we add one ounce of lift to lift it up in the air." "If you guys want to go 500 yards, that's a long way." "So we'll see how a 2-ounce rocket works." "NARRATOR:" "Using six-inch cardboard tubes," "Bill shows how to pack a charge without blowing up the bunker." "GRANT:" "And so you do a little bit at a time," "and you compress that." "BILL:" "You put the rod down in, and you just give it a couple hits." "Feels wrong." "Go ahead." "Don't hit it too hard, man." "I'd hate to see you blow your hand off." "Good?" "GRANT:" "Nice." "NARRATOR:" "Grant and Tory make several versions, some with more black powder and some with less." "All right." "We need to see if these arrows can fly 500 yards." "So we should walk it out." "NARRATOR:" "They're here to test part 1 of the myth -- that a rocket arrow really could make the distance." "But 500 yards is a long, long way." "TORY:" "Isn't this how all horror movies start?" "[ Laughs ]" ""Didn't that guy say stick to the path?"" "This is gonna be perfect." "We're right at the tree line." "NARRATOR:" "The crop ends smack-bang on the 500-yard mark." "They tape the target halfway up a tree so they can see it from the launch site." "GRANT:" "At this point," "I think we're just going for distance rather than aim." "But if I were to take a guess to see whether the arrow would hit him," "I'd have to say we probably wouldn't." "Then again, the hwacha had 200 arrows." "NARRATOR:" "Back at the business end, they set the mortar to 45 degrees..." "GRANT:" "Back up." "NARRATOR:... and start with the smallest rocket." "If this baby-bear rocket reaches the trees, they can pack up and go home." "GRANT:" "Yeah!" "TORY:" "Nice!" "It didn't really work!" "I'm gonna have to say it went about zero yards." "GRANT:" "Not enough thrust." "TORY:" "Yes." "It does look a little embarrassing that this is our first rocket that we built and it doesn't even fly." "But that just means this rocket's too small and the arrow's too heavy." "NARRATOR:" "So they try the mama-bear charge." "GRANT:" "Back up." "NARRATOR:" "But it still more blows than goes." "GRANT:" "Cool!" "There's a lot of reasons why these might not be working." "Maybe we didn't pack the black powder tight enough." "The nozzle might be the wrong size or the arrows are just too heavy, and this rocket can't give it lift." "But we're not gonna give up." "NARRATOR:" "So Grant tries a rocket with more powder and a smaller nozzle." "TORY:" "Quick!" "They're charging!" "Whoa-ho-ho!" "[ Both laugh ]" "Nice!" "That was nuts!" "[ Laughs ] Did you see it go, spiral around?" "TORY:" "All right." "I'm gonna see if I can go find that." "GRANT:" "Good luck." "TORY:" "Wow!" "Grant!" "Whoo!" "That went more than halfway." "GRANT:" "Yeah -- 290 yards." "TORY:" "As beautiful as that was, it's still not good enough for this myth." "I mean, the arrow only made it to 290 yards." "We're not stopping until we reach 500." "NARRATOR:" "For that, they'll need to double the charge by strapping on two black-powder engines." "But will the arrow bear the weight?" "Grant adjusts the angle to 50 degrees." "That is right on the money." "NARRATOR:" "This field test is all about going the distance." "Landing short would make this myth a misfire." "GRANT:" "Come on, baby." "Come on, hwacha." "Come on!" "Come on!" "Whoa!" "[ Laughs ]" "Keep going!" "Keep going!" "Yeah!" "GRANT:" "Oh!" "That looked like it exploded above the trees." "Yes!" "I think it exploded over the trees, man." "That's 500 yards, buddy." "That went the distance!" "Yeah!" "NARRATOR:" "The target's untouched, but they've got what they came for." "They reached it." "This part of the myth is confirmed." "God, this is gonna be a nightmare trying to get all 200 arrows to fire off at the same time." "And we've still got to make the cart and find out if that explosive charge is mortally wounding." "We got a lot of work." "We'd better get back to the shop." "All right." "NARRATOR:" "Adam, Jamie, and Kari are risking their lives -- uh, that should read "livers" -- to test the myth of beer goggles." "This is the best day at work ever." "[ Laughs ]" "NARRATOR:" "They've all done the test sober and then buzzed with varied results." "Time to raise the stakes..." "I think it's time for a Scotch." "NARRATOR:... and maybe lower their standards." "What are you gonna have?" "Whatever's in that brown bottle." "NARRATOR:" "Hard to beat a drink of something... brown." "Kari still has a lot to learn, like, "Don't tease the wildlife."" "Can I style you?" "Hold on." "You know, I usually don't let people do that." "ADAM:" "I don't know about you, Jamie, but I'm ready to take this test, and I know that Kari is." "NARRATOR:" "Adam blows. 11..." "ADAM:" "That's good enough." "[ Exhales deeply ]" "NARRATOR:... and Jamie,. 10." "That works." "NARRATOR:" "So technically, they're both a bit wobbly." "[ Exhales deeply ]" "NARRATOR:" "As for Kari... . 13." "[ Laughs ]" "Dude, you are so ready for this test." "NARRATOR:" "In fact, they're all well primed for part three of the beer-goggles challenge." "These last 30 faces are a random mix of those they've seen sober and buzzed." "She's pretty darn cute." "8." "She's very cute." "I've met her." "It seems like in each group, there's a lot more cute chicks." "NARRATOR:" "When he's done, Adam's score reflects his growing enthusiasm." "134?" "!" "Wow." "NARRATOR:" "But the wild card here is Kari." "She was far harsher buzzed, so this could be anything." ""Kari Drunk."" "NARRATOR:" "Kari correct." "Her 30 guys look set for another beating, assuming she can still see straight." "You look homeless but kind of cute." "He's all right." "NARRATOR:" "Even Kari's surprised that the tide might be turning." "KARI:" "When I was sober, I was definitely thinking that confident-looking people looked sort of attractive." "And then as I was buzzed, they looked cocky." "And then as I got drunker, I was sort of thinking that the people that were attractive were sort of the more vulnerable-looking people, sort of like the more sadder characters." "They just " " They looked cuter." "NARRATOR:" "And that's why men will never, ever guess what a woman is thinking." "Kari's score is 153." "I can't remember if that's higher or lower than either of my scores." "NARRATOR:" "That's a 64-point jump from last time." "As for the man bent on putting reason back into romance..." ""Jamie Drunk." Start." "Drunk, buzzed, sober " "An apple is an apple, and an orange is an orange." "There we go." "[ Ding!" "]" "Drunk score, 111." "NARRATOR:" "From stone-cold sober to stinking drunk," "Jamie's judgment varied by just 11 points." "Basically, what I'm saying is that I don't see that I'm subject to beer goggles." "NARRATOR:" "With three very different results, they'll make or break this myth by checking the numbers." "I don't know about you two reprobates, but I don't feel in any condition to crunch any numbers." "I think we ought to go home, drink a lot of water, sober up, and come back tomorrow." "Did you say you were calling a taxi?" "Taxi." "Absolutely." "Looks to me like we all had very different reactions to the alcohol." "What do you two make out of it?" "I'll tell you what I see." "If this myth were totally confirmed, all three of our graph lines would look like mine -- a steady improvement in our assessment of the attractiveness of the opposite sex, directly in proportion to the amount of alcohol we consumed." "It definitely looks like I was way harsher when I was buzzed than when I was sober." "And I look pretty consistent, all in all." "However, I'd like to point out that both of you showed improvement from being buzzed to being drunk." "That result, combined with my steady improvement all along the line, tells me this one is easily plausible." "Definitely plausible." "Okay." "Plausible." "NARRATOR:" "Adam and Jamie have already drunk themselves sideways for science, but there's no time to sleep it off." "In fact, that's exactly the point of our next myth." "Well, I've been thinking, along the lines of drinking myths," "I have always wanted to do sobering-up techniques, specifically 'cause I've always wanted to see a high-speed shot of somebody getting smacked in the face." "Well, as long as that somebody is you, I'm okay with it." "ADAM:" "Almost since the invention of alcohol, people have been drinking too much and then finding, for one reason or another, that they needed to get sober quickly." "And they have tried a myriad of techniques -- techniques like drinking a big cup of black coffee." "Vigorous exercise is also supposed to work." "Dunking your face in some ice water." "That's also supposed to work!" "Also, your friends might be inclined to smack you in the face to sober you up." "Of course, it all begins at the bar." "And although we're gonna test every one of these, we've got to get drunk first." "Buster, set me up." "NARRATOR:" "So the boys fall back off the wagon." "So, you in town for a long time, or you here for the convention?" "Shut up." "Leave me alone." "There's those people skills hard at work." "NARRATOR:" "And that's just the first shot of five." "Realizing that things might turn ugly, the producers got Adam to prerecord the plan." "[ Coughing ]" "Because this whole story hinges on whether or not we are more or less sober, the researchers have found us the perfect test to determine that." "This is a hand-eye coordination test that's very similar to one developed for astronauts." "It simply involves staying at arm's length from the screen with weights on your arm and tracing this gray line." "We are scored on both accuracy -- how many times our line leaves the gray line and for how long and speed -- how long it takes to make the whole journey." "We've got a number of these." "They're all different, but they're all the same length and involve the same number of turns." "Jamie and I will each take one of these tests before trying a sobering-up technique and take another one after trying the sobering-up technique." "And we will each act as each other's controls, swapping out between techniques." "Na zdorov'e." "Na zdorov'e." "[ Groans, growls ]" "NARRATOR:" "They'll need to stay consistently drunk to validate the cures." "JAMIE:" "This is like taking medicine or something." "It takes all the fun out of it." "ADAM:" "I know what you mean, brother." "[ Glass shatters ]" "NARRATOR:" "Tory and Grant have checked off the first part of the hwacha myth." "A bamboo arrow with a gunpowder engine can fly 500 yards." "Part 2 of the test is to see if the arrows were double-deadly " "A warhead filled with more gunpowder was meant to explode on impact." "But will it do more than just singe the skin?" "Only one way to find out." "Tory prepares a leg of pork..." "Ah, you filthy little pig." "NARRATOR:" "...Grant inserts the fuse, and hopefully we're makin' bacon." "This is tissue-damage test on pork." "In 3, 2, 1..." "TORY: [ Laughs ]" "Wow!" "Wow!" "That's good." "[ Laughs ]" "Wow." "Look at that." "More burning of flesh." "GRANT:" "All right." "But as far as making it a mortal wound that explodes inside you..." "Yeah, the arrow itself is probably gonna do more damage than the explosion." "NARRATOR:" "But we're testing for deadly injury, so it's worth rewrapping the warhead to push all that explosive energy forwards." "That's a larger exploding arrow." "I think the boys really were hoping for some sort of -- blah!" " gore and mess." "But what really happened is, the energy took the path of least resistance." "In 3, 2, 1." "[ Laughter ]" "Whoa!" "Wow!" "Look at how much damage that did." "That's a little more what you were looking for." "NARRATOR:" "And exactly what they were hoping for." "This is the same amount of black powder as the test before." "The only difference is how we contained it." "Now, before, we had a thin paper tube." "The tube blew out, and all the energy was being released." "In this test, we sealed both ends of the container and had a small fuse going in." "So all that energy that was being lost built up, built up, built up, and ba-boom!" "Big wound." "NARRATOR:" "That's two-thirds of the legend confirmed." "The arrows can fly 500 yards, and they can cause serious additional damage when they explode on impact." "To test part 3, whether 200 arrows really could fire together, they need to build their own replica hwacha." "Tory gets stuck into the carpentry... while Grant carves a life-sized army of Styrofoam soldiers all fated to end their days as Korean cannon fodder." "Since Tory told us about the hwacha," "I've been doing a little bit of research about it." "It turns out that the first one was made in 1409 during the Choson Dynasty by Korean scientists." "But they say that one wasn't used in combat." "Yeah, and by 1503, it had become such an effective weapon that in the Battle of Haengju," "3,000 Korean soldiers and 40 hwachas repelled over 30,000 Japanese troops." "So they were outnumbered 10 to 1." "Yeah." "In fact, at that time, the hwacha had become a primary defensive strategy." "They just lined the borders with them." "That's cool." "I hope ours can live up to that legacy." "NARRATOR:" "Tory has exceeded all expectations, building a near-perfect hwacha based on nothing more than photos." "He adds a splash of timber stain and some old-timey wheels." "TORY:" "And the wheels also act as an angle finder, so you can find the best angle for your trajectory." "This is going to be awesome." "Grant's army does not stand a chance." "NARRATOR:" "Adam and Jamie are all set to test four mythical ways to sober up fast." "[ Glass shatters ]" "Uh-oh." "NARRATOR:" "So far, all they've done is drink themselves stupid." "Well, stupider." "While Adam stays pleasantly pickled," "Jamie tries the first detoxifier." "The idea is black coffee!" "What are you doing?" "I'm the control." "See..." "I don't think you're very much under control." "I'm not under control." "I am the control." "You drink that whole cup of coffee, we wait five minutes, and then we test you cognitively and Breathalyzer-ly again" "to see if there's any stark improvement." "And then I do the same two tests to see if there's a difference in the improvement." "Whenever you're ready." "You're rapidly improving." "I don't know what to make of that, but..." "I don't feel like crunching any data while I'm drunk." "Okay." "And it's all about the data." "ADAM:" "Oh!" "NARRATOR:" "Adam, who also blew .07, completes his non-coffee control test." "32!" "[ Laughs ]" "NARRATOR:" "So it's back to the bar." "Adam treats himself to a few cups of joe so he and Jamie are back on a kind of even keel." "[ Chuckles ] Here's mud in your eye." "Oh, this is vile." "NARRATOR:" "Now for a much-needed spurt of spirits." "ADAM:" "On the assumption that the average adult male of our size processes -- metabolizes, as you might say -- one drink per hour, we are having a maintenance drink right now." "NARRATOR:" "It's about now we'd normally warn you about excessive drinking." "But those two miserable mugs tell the story." "This blows." "NARRATOR:" "Technique number two for sobering up is vigorous exercise, and Adam's the guinea pig." "It's all a numbers game, and here's a few more to consider." "Adam has to run this treadmill for five minutes at 6 1/2 miles per hour." "This is scary." "NARRATOR:" "His blood alcohol is .09." "[ Laughs ] Wow." "I'm gonna have to concentrate on this."

"I'm gonna die." "JAMIE:" "Look, we picked a treadmill because it's compact." "It makes it easy for us to film this thing." "But now that I'm looking at it," "I remember that it takes a fair amount of coordination just to stay on the damn thing, and Adam's drunk." "NARRATOR:" "What can I say?" "Even soused, the man's a prophet." "Whoa!" "Aah!" "Oh!" "[ Clang ]" "Okay." "I'm totally cool." "NARRATOR:" "Now, here's two advantages to being drunk as a skunk."

"And now they're down to two mythical cures that should at least be mercifully brief." "The first is a face-freezing dunk in ice water." "Adam's the control, so Jamie gets his eyebrows iced." "I think within the pantheon of sobering-up techniques, cold water is in the shock-to-the-system category." "I guess just in the same way it can -- oh!"

"NARRATOR:" "Adam's feeling no pain." "But that's about to change." "Oh!" "[ Laughs ]" "Holy crap." "[ Laughs ]" "Holy bleeping bleepity bleep!" "[ Laughs ]" "Can I do that again?" "That was kind of fun." "No." "That made my head ring." "ADAM:" "It definitely took my mind off feeling crappy and drunk." "But I think that's the same effect " "It's like if you feel hurt, you drink a little alcohol, and you wouldn't care so much about being hurt." "It's like the opposite effect." "JAMIE:" "Here it comes." "ADAM:" "Oh, crap." "[ Both laugh ]" "Oh, my God!" "My whole " " Oh, my God." "[ Laughs ]" "JAMIE:" "It's like your whole head is rubber." "ADAM:" "That's the funniest thing I've ever seen." "NARRATOR:" "For the last time, the boys blow the bag and trace the graph." "[ Beep ] 21 seconds." "[ Marker clangs ]" "NARRATOR:" "They're far too drunk to know what worked and what didn't." "But the stats they've gathered will tell the story." "[ Both mumbling ]" "Sobering-up techniques." "This looks pretty slick." "Is it gonna help us wrap it up?" "In fact, it will." "Let me walk you through it." "This is you pre-coffee." "Then you drank three cups of coffee, and your score improved." "However, I was the control, and my score improved pretty much at the exact same rate." "So I'd say coffee is busted." "Now, here is me pre-exercise." "Here is me post-exercise." "That's a pretty radical improvement." "But I stayed about the same, so that means it's plausible, right?" "I totally agree." "Plausible it is." "Now, you were the one that dunked your head in a bucket of ice water." "Here is you before." "Here is you after." "Little lack of improvement." "Mine was about the same." "I say ice water is totally busted." "What about the slap?" "My favorite." "ADAM:" "Okay. [ Laughs ]" "Here is me pre-slap." "Here is me post-slap." "I think that's a pretty undeniable radical improvement." "You helped me out a lot." "I'd say this one's plausible." "I'll have to remember that." "ADAM:" "[ Laughs ]" "The best part is, all of these results are totally backed up by the Breathalyzer data we got as well." "I guess that does wrap it up." "Totally." "No more drinking for us." "NARRATOR:" "All famous conflicts have an equally famous battlefield " "Gettysburg, Guadalcanal, and in this case, the Teichert Quarry." "GRANT:" "This is it." "KARI:" "Teichert Aggregates." "TORY:" "Do they have any idea what we're gonna do today?" "GRANT:" "No." "KARI: [ Laughs ]" "NARRATOR:" "No one doubts the existence of this medieval Korean arrow launcher." "But many doubt its capabilities." "We've surprised ourselves by proving these rocket arrows could fly 500 yards..." "Grant!" "Whoo!" "NARRATOR:" "...then explode on impact." "Whoa!" "Wow!" "NARRATOR:" "Now to see if they can all launch together to devastate Grant's grunts." "Drafted, drafted." "It's a good thing you got a light infantry." "GRANT:" "Oh, how long you been saving that one?" "NARRATOR:" "Not long enough." "Now all 200 arrows need to be charged, and it's safety first." "TORY:" "We're starting to build our rockets and attaching our explosive heads." "But just like Zambelli's, we're separating our stations." "So if one of us goes up, we don't take all the rest out with them." "GRANT:" "Tory and I will be adding the black powder and sealing up the warheads." "And we'll pass these off to Kari, who will be putting the rockets in their final tubes and attaching them to the arrows." "TORY:" "I've been making fireworks since I was a little kid -- 30 years." "I never had a problem." "NARRATOR:" "When the arrows are finished, the star of the show is coaxed from the trailer." "Hwacha!" "KARI:" "There you go." "It's free." "TORY:" "Let's roll it into position." "NARRATOR:" "Tory sights the machine on level ground, and he's covered all the angles." "TORY:" "All right." "And this is a 50-degree trajectory." "All right." "Well, army's gonna be right over there." "All right." "Let's measure out 500 yards and set up your army." "NARRATOR:" "Grant's army is just 50 strong, staked out in a loose skirmish formation." "GRANT:" "When it comes to recruiting foam people, they're not that bright." "So it's easy to convince them to stand out there in the field." "You ready to load the hwacha?" "KARI:" "I'm getting excited." "NARRATOR:" "I must say I'm getting a little enthused myself." "All 200 tubes are loaded." "TORY:" "Something's gonna happen." "NARRATOR:" "And they know they'll only get one shot at this." "GRANT:" "Okay, so all the individual arrows are now fused." "And the idea is that we group them together and just keep grouping them together, grouping them together, until in the end, we have one final fuse that we light and then run away." "This is actually the coolest ancient weapon we've ever made." "NARRATOR:" "But will the hwacha live up to its reputation?" "Kari's prepared to stake hers." "KARI:" "I think it's gonna take down the army." "I'm guessing at least 50 % go down." "NARRATOR:" "And that's got the infantry trembling in its boots." "Grant sallies forth to light the master fuse..." "TORY:" "Quick!" "Your army is attacking!" "Run, Grant!" "NARRATOR:" "...then toddles back to safety." "GRANT:" "It's going." "TORY:" "We got a little bit of time here." "NARRATOR:" "They know something's bound to happen." "But will these arrows all take off together?" "GRANT:" "Another 30 seconds." "You can see multiple fuses going." "NARRATOR:" "Or will the hwacha just blow itself to pieces?" "TORY:" "Look at all the smoke." "NARRATOR:" "The tension builds as the fuse burns down." "No one knows just when or even if the last part of this myth will catch fire." "TORY:" "Something's happening." "Something's happening." "KARI:" "They'll light each other." "GRANT:" "[ Laughs ]" "[ Cheering ]" "[ Arrows whistling ]" "NARRATOR:" "It's the launch of a lifetime." "A spectacle not seen by man nor beast in 500 years." "And every arrow but one took flight." "[ Cheering ]" "GRANT:" "That was fantastic." "Just seeing all the rockets come out of the hwacha at once -- beautiful thing." "Seeing that would be terrifying." "Absolutely terrifying." "Oh." "Hey, look." "That's the one that went short." "NARRATOR:" "It's an awesome enough sight side on." "Half a dozen arrows dropped short, and the army's still upright." "But this myth is far from busted." "GRANT:" "Well, the army's still standing." "TORY:" "Yeah, and you know what?" "There's not a lot of arrows in this area." "KARI:" "Where'd they go?" "TORY:" "I don't know." "They're around here somewhere." "They've all grouped right over here." "GRANT:" "Oh, wow." "That's a great grouping, actually." "TORY:" "That's incredible." "Like, they were pretty consistent." "KARI:" "Oh, there are definitely army over here." "We only had 50 soldiers." "Imagine if we had like 3,000, 30,000, 300,000." "NARRATOR:" "Kari's right." "The troops wouldn't be so few or so scattered." "So this rocket attack would be devastating." "All right." "So, hwacha -- confirmed?" "Confirmed." "They all left and they exploded." "Absolutely confirmed." "All right." "That was a good one, man." "[ Hawk screeches ]" "KARI:" "The hwacha worked on many levels." "But most of all, it was frightening." "All of those arrows flying into the air on fire and exploding would definitely make me turn around and run." "TORY:" "That was a success." "I mean, we got all the arrows to fire off except for one, and they all went the distance and they all exploded." "Okay, maybe we didn't take out the army." "That's just because our aim was off." "But if we had been aimed right, we would have killed this army!" "NARRATOR:" "We knew it existed, but no one knew for sure what the hwacha was capable of."
