"Behind me, the Hyneman watches hundreds of feeds from "MythBusters" of years past but not out of narcissism." "No, this has a purpose." "The powers that be have allowed the Hyneman to sift through all the constructions that he's done over the past 10 years to find one that he found unsatisfying and wants to revisit, one that will bring a smile, an invisible smile" "underneath his prodigious moustache." "Would you shut up?" "Narrator:" "Yeah, can it, Adam, because this episode is all about second chances." "With over a decade of episodes and 850 myths to choose from..." "Two... one." "...they've scanned the archives for their greatest, unsolved myth-teries." "Adam and Jamie have a blast from the past..." "Adam:" "Whoa!" "...As they mix dynamite and DIY once again."

"MythBusters 12x09 - Painting with Explosives / Bifurcated Boat" " Original air date June 26, 2013" "First, Adam and Jamie are brushing up on their arts and blasts." "For those of you playing at home," ""painting with explosives" is a show we did years ago based on an episode of the British comedy "Mr. Bean"..." "[ Film reel clicks, whirs ]" "In which a stick of dynamite is placed in a bucket of paint." "[ Explosion ] And when it blows up, it perfectly paints the room it's in without destroying the room." "Yeah, but our explosives didn't do a very good job of it, did they?" "No." "I think we ended up more, like, staining the walls than actually painting them." "Yeah, it was a Jackson Pollack sort of a moment." "Yeah." "Barely." "Yep." "The last time we tested this weapon of mass decoration one." "...our painters and detonators..." "Coverage... total crap." "...got paint on the walls..." "That's horrible." "...but you wouldn't call it home improvement." "So, you think you can actually do it this time?" "You have a new design in mind?" "Well, I'd like to try." "And as you know, I have a thing about actually harnessing the power of explosives to do work instead of just blowing crap up." "I have some ideas of my own." "Let's say, for this episode, we go off to our separate corners and each try a solution and see if we can't finally achieve painting with explosives." "Sounds like fun." "All right." "Boom." "[ Bird cries ]" "So, the guys will split up and each craft their own room boom." "But that's going to take some bomb-range R and D." "What a lovely day." "Let's blow something up." "Narrator:" "And first to take up the brush is Adam." "I'm going all the way back to basics." "I'm gonna take a little chunk of C-4 and a bag of paint and a surface, and I'm gonna blow up the C-4 and watch what it does to the paint on the surface." "Narrator:" "So, Adam's plan is to start small..." "C-4 goes here." "Paint hangs here." "My test canvas goes here." "Narrator: ..." "Under the watchful eye of J.D. Nelson to explore what happens when paint meets explosive meets canvas." "[ Siren blaring ] Painting with explosives." "First experiment in three, two, one, go." "Fascinating." "Fascinating." "It just, like, goes, "pbht."" ""Pbht."" "That's not at all what I expected to happen." "That's information." "That was the whole point of this test." "That fraction of coverage is a long way from what Adam needs..." "Boom." "Pbht." "...and the action replay reveals why." "Adam:" "Whoa." "The paint's still there." "Wow." "It's totally not vaporizing." "Its' too far away." "That is radical." "Awesome." "Okay." "I know what to do next." "[ Grunts ] Narrator:" "Yep." "For test two, Adam's got something different on his plate." "So, the difference between this blast and the last one is that I am going to move the paint much closer... in fact, right on top of the C-4... and second, as you probably already surmised by this," "I'm going to give the C-4 a reflecting backing plate, this big, heavy piece of steel." "Oh, cool." "There it is." "There you go." "I'm not actually sure if this is gonna work, but it's gonna be really different than the last one, and that's gonna tell me something." "[ Siren blares ]" "In three, two, one, go." "Whoa!" "[ Laughs ]" "That was far more effective." "Narrator:" "The backing plate certainly reflected the paint onto the board and everywhere else." "[ Lens squeaks ]" "Adam:" "There we go." "Hi, there." "How you doing?" "Hi." "The high-speed shot of my blue-paint explosion is absolutely gorgeous." "I got exactly the vaporized fog of paint that I was looking for, and most of it ended up on the four-by-eight of wood that I had placed there to receive the paint." "It's about as far as you'd get if you wanted to roll that much paint onto that board." "Narrator:" "And that's exactly the kind of coverage Adam was looking for." "But he still thinks he can improve on it." "In this test, I'll be using this." "It's actually a thin sheet of plasticized, sheet explosive, sort of a C-4 jerky, if you will." "But don't eat it!" "[ Laughs ]" "No." "I'm gonna paint with it." "[ Teeth clacking ]" "Narrator:" "But will spreading the explosive under the paint also spread the coverage?" "[ Siren blares ] All right, here we go." "Final explosion in three, two, one, go." "[ Laughs ]" "That was more powerful than I expected it to be." "That was a little too much oomph." "[ Chuckling ] Well, let's go see how it did with the painting anyway." "[ Laughs ]" "Narrator:" "It was less a lick of paint and more a riot of color." "That goes there." "But piecing back together his canvas has inspired Adam." "Well, for me, that was a very successful and excellent day and not just because I spent the day blowing stuff up." "Because in blowing stuff up, I actually learned..." "I believe I learned everything I need to know to paint with explosives, including how much explosives is too much." "Time to get to work." "Narrator:" "So, Adam heads back to the shop, where another mythbuster has been playing with his nozzles." "Jamie:" "The way I see it, if I can get a single blast of paint going through a nozzle to cover an entire wall perfectly evenly, then if I have multiple nozzles painting multiple walls," "I can get a single blast of paint to paint a whole room." "I'm thinking that this sort of flattened orifice here is restricting the paint to where it doesn't come out in a cone, but rather, it comes out in a rectangle." "And that's exactly what I need." "Narrator:" "It's exactly what he needs." "But a hose is a long way from an explosion." "Jamie:" "With that in mind," "I've broken out this rig that I built some time ago because it'll allow me to test with up to about 700 P.S.I., and we'll see if that fans it out more." "Narrator:" "Jamie's aiming for a rectangular spread onto the wall." "Too far open." "But it's a delicate business of tweaking his nozzle just so..." "I liked the first one better." "...until eventually, he finds his goldilocks ratio." "Three, two, one." "[ Laughs ]" "It's looking pretty good." "Narrator:" "Yep, and with his nozzle in hand," "Jamie heads to the bomb range..." "[ Tires screech ] ...to put part two of this theory to the test." "Solid as a rock." "My theory is that this time around, we need to contain the paint and the explosives in something like this high-pressure, scuba tank, and when the explosives go off, the paint will be propelled out the nozzle of the tank" "kind of like a spray nozzle." "And we'll end up with our nicely painted wall, hopefully not a pipe bomb." "Narrator:" "Yep." "Jamie's method all comes down to pressure." "But first, what happens when you put explosives inside a tank of paint?" "[ Siren blares ] All right." "This is test one, C-4, no nozzle, in 3, 2, 1, go." "Ah." "That... that actually is quite nice." "It looked like it sent most of the paint out." "No rupture." "Narrator:" "It didn't blow, so tank two is filled with paint and then fitted with the patented, Hyneman nozzle." "But will the combo of rectangular nozzle and pressurized paint cover the wall?" "[ Siren blares ]" "In three, two, one." "[ Laughs ]" "Uh, well." "Narrator:" "Once again, the tank survived, but the nozzle doesn't seem to have made any difference to the coverage." "Jamie:" "We're pushing the limits with what we can get with these tanks, and the fact is that I'm not creating the kind of spread that I need." "I need more pressure to get that spread." "So, I think it's back to the drawing board." "Narrator:" "Later, can the MythBusters make high art with high explosives?" "Jamie:" "Go." "Oh, my gosh." "And Kari, Tory, and Grant weigh anchor on water." "Mythity split it." "But will the curse of the bifurcated boat return?" "Narrator:" "The MythBusters have been testing, confirming, and busting for over 10 years." "And now they're closing the case on some unsolved myth-teries." "Now, if you guys don't remember the story, it goes like this." "A man is driving his speedboat out of control and crashes into a channel marker, almost splitting the boat in half." "Now, he tells the insurance company that he was only traveling at 25 miles an hour." "Kari:" "When we tried it, we couldn't split the boat." "We couldn't even get a tear." "Yeah, our results were less than spectacular." "But according to you fans, that's because our methodology was totally wrong." "Because we didn't do it on water." "Exactly." "So, right here, right now, we are gonna retest it." "We're gonna kill two birds with one stone." "Narrator:" "It was the myth they said was cursed." "But despite the rain..." "I'm pretty much over this one." "...the problems..." "Did we lose the cable?" "[Bleep] [Bleep] ...the arguments..." "Dude, we never use the blue rope." " We always use the blue rope!" " No, we haven't." "...and the accidents..." "Yeah!" "Whoo!" "Ohh!" "Narrator: ..." "The guys could never split the boat." "Oh, the story's busted at 25." "However, the fans say this land-loving test..." "[ Laughter ] ...was a flub." "All right. 10-year take 2." "What's the plan?" "Well, it's obvious." "We have to test this on water just like the fans asked." "Well, we need a boat and a channel marker, but how do we get the two to crash?" "Why don't we do it the same way?" "This time, we just use powerboats." "You make it sound so easy." "Now we're older and wiser." "We are older." "Narrator:" "Yep." "Although the myth is the same..." "crash a speedboat at 25 miles an hour into a channel marker... instead of testing on the runway, they'll float their boat on a lake." "And rather than using a tow truck, they'll use a pair of towboats." "So, to weigh anchor on water..." "It's off to Big Break Marina in Oakley." "Kari:" "So, that's the boat." "Oh, that is awesome." "There she is." "That brings back memories..." "and not all of them good." "Tory:" "Now, remember, we have to crash our boat into a channel marker." "Now, as you can see, this marina is filled with them." "But for some reason, they don't want us to crash our boat into theirs." "So, we need to plant our own." "Now, this is no easy job." "I mean, we're talking about a 40-foot pole being sunk 12 feet into the ground while on top of the water." "And luckily for us, Rob, our friend here, has a floating pile driver." "Narrator:" "Indeed." "And with Rob driving our pole into the delta..." "[ Pile clangs ] ...it's time to shape up and ship out." "Kari:" "We've removed the engine just like last time, so we're going to replace the equivalent weight of the engine with barrels full of water." "Narrator:" "And with the barrels aboard, it's time to hit the waves." "Check for holes." "Step one, it floats." "It floats." "And now to give it the equivalent ballast of an engine." "[ Pump whirs, hums ]" "But to get it moving on water, it's gonna need help." "These are our towboats." "That's right." "You heard me." "Two boats." "Because there's too much water resistance for just one." "Each of these boats has a 175-horsepower engine." "That should be plenty of power to get our speedboat up to 25 miles an hour." "Narrator:" "Up to 25 miles per hour..." "Aaaagh!" "...and into the newly installed, picture-perfect channel marker." "Before we rig all the important components to this experiment," "I thought we needed a little authenticity and make this look just like the viral photo." "Narrator:" "And with the tow system working, they're ready to test." "But while the cameras reset..." "[ Horn blows ]" "Tory:" " What the [Bleep] Kari:" " Oh, no!" "Oh [Bleep]." "...tragedy strikes." "Tory:" "You're probably wondering why there's a giant barge in the middle of our channel, and we were wondering the same thing." "And then, that barge got closer and closer to our channel marker, and it actually knocked it over into the water." "In fact, our crew, right now, is looking for it, trying to fish it out." "Did you guys find it yet?" "Not yet." "This is so "MythBusters."" "I mean, everything was going so smoothly." "Something had to go wrong." "Narrator:" "But unlike the marker, this myth ain't sunk yet." "[ Film reel clicking ]" "Could painting be as easy as "three, two, one, boom"?" "[ Laughter ]" "Well, when the MythBusters tried this, their TNT DIY was D.O.A." "I thought it would be a little better than that." "Now, armed with seven years' more explosives experience, their first stop was painting and detonation 101." "Adam:" "That's information." "That was the whole point of this test." "Narrator:" "And back at the shop," "Jamie's "tankful" for all that research." "Having seen this tank darn near rupture from an explosion points out the fact that when an explosive goes off, the energy from it wants to travel outward evenly in all directions." "It's almost a spherical swelling." "So, you know, maybe a cylindrical tank isn't the way to go." "Maybe we need a spherical tank." "But the problem is that you can't just go to the store and buy one like you can a scuba tank." "You got to make your own, and that's not a simple task." "Narrator:" "Not a simple task, but the Hyneman mind will find a way." "In fact, it looks like he already has." "Jamie's thought up an ingenious, flat-pack design for his spherical tank." "Jamie:" "There we go." "24 one-inch-thick washers and 26 assorted other parts to bolt it all together." "Looks like it ought to weigh around 3,500 pounds." "[ Laughs ] That's a big, heavy sphere." "Narrator:" "Yep." "That's no moon." "[ Respirator hissing ]" "So, it's off to get those washers plasma cut and then put it all together." "So, when this is all assembled, it should hold upwards of 50,000 P.S.I. from the blast." "At least, that's the plan." "Narrator:" "That's the plan, but with over 50 parts all cut from one-inch, heavy-duty plate..." "[ Grunts ] This thing's a beast." "...that's one giant, 3-D puzzle." "But as it's a brainteaser of his own design," "Jamie has this riddle wrapped in an enigma all figured out." "Jamie:" "The sphere's being made in two halves, and each half is basically a stack of different-sized washers that get put on top of each other and welded together." "Now, the holes leave a 10-inch-diameter cavity in the middle of this sphere, and that's where the paint and the dynamite goes." "There we go." "Now, when the explosive goes off, all of that paint has got to go somewhere, and so, I'm hoping that it'll go right into these sort of funnel shapes in these nozzles and straight out and paint our walls." "What it actually will do as far as painting a house," "I'm not really sure, but I'm having a ball." "Narrator:" "Get it?" "He's having a ball." "And as he works long into the night, it's clear Jamie's sphere has turned to the dark side." "[ Ominous music plays ]" "[ Respirator hissing ]" "Jamie:" "You know, if you want to contain a high explosive, that's what you got to do." "[ Laughs ] That's pretty." "Well, while Jamie's working on whatever flower of death he's building back there behind the forklift," "I have been thinking seriously about the explosions that I got out on the bomb range." "[ Harp plays ]" "[ Bloop!" "]" "Oh." "Right." "So, they have given me the ideas that I need." "I've got all the steel cut." "I'm about to start constructing my painting device here in the shop." "Narrator:" "Yep." "And just like the Hyneman, Adam's device ain't simple." "There's a lot of moving parts to this painting rig, but it's gonna be cool." "Narrator:" "Adam welds some frames, and then... well, we're not quite sure what he's doing." "[ Grunts ]" "Whew!" "Coming along." "Narrator:" "And that's exactly how he wants it to stay." "All right." "At this point, I'd like you to take a moment and speculate on how you think my painting machine works." "'Cause you know what's cool?" "You're totally wrong." "I'm going way off the reservation on this one." "Oh, what modern inventions will we come up with next?" "Narrator:" "So, with Adam's secret device apparently complete and Jamie's giant death sphere on the back of the truck, the war on walls can begin." "Jamie:" "Three, two, one, go." "Narrator:" "At the Big Break Marina..." "[ Horn blows ] Tory:" "What the [Bleep]" "Kari:" "Oh, no!" "...there's been a big barge break." "And it seems as though the bifurcated-boat curse is back." "Ah, good, old, bifurcated boat." "In the great tradition of the mythity split, this is a completely cursed experiment." "We lost our channel marker to that barge." "But luckily, we've procured another." "The bad news is we do lose a little authenticity as our seagull and our sign are at the bottom of the lake." "[ Bell tolls ]" "Go ahead, Tory." "Back it in." "Narrator:" "Yep, with 10 years of experience, our crew certainly knows how to salvage a myth." "And thanks to their quick thinking and resourcefulness..." "I feel like we've done this before." "'Cause you have." "...pole two is good to go." "And now that the fans are getting their watery way, just how much difference will testing in the drink make?" "Grant:" "So, what's the big deal with water?" "Well, here's why it might make a difference doing it on water this time." "The boat is sitting on the water." "Water is incompressible." "That means that there's pressure on the hull." "That extra pressure might translate into more impact force on the bow, potentially allowing it to split." "Second reason is that the keel is now in water, helping to keep the boat straight, so you avoid possibly getting a glancing blow." "Now, why might it not make a difference?" "Well, think about it." "The weight of the boat is the same." "The speed is gonna be the same." "Therefore, we're gonna have the same amount of kinetic energy hitting that pole." "What do I think is gonna happen?" "I don't think we're gonna get a split, at least not at 25." "[ Engine turns over ]" "Narrator:" "Grant's skeptical, but after their cursed morning," "Tory is hoping they can actually push the boat out." "[ Ducks quacking ]" "Tory:" "All right, there should be one word going through your guys' heads right now, and that's "bifurcation."" "But will testing this myth afloat split the boat?" "All right." "The boat's in place." "Channel marker's up." "Tory:" "This is bifurcated boat, take two." "Mythity split it." "In three, two, one, hit it." "Narrator:" "The towboats accelerate..." "And the mythity split takes off..." "[ Ducks quacking ] There's the boat." "Oh, the rope's tensioning!" "Grant:" "Boat's away." "Oh, here it comes!" "Wow." "Okay." "Narrator: ..." "Slowly speeding up to the mythical 25 miles per hour." "Tory:" "Here comes the boater!" "That looks so crazy." "Ghost boat!" "Oh, it's beautiful." "Narrator:" "But will the channel marker finally make its mark?" "Tory:" "Come on, come on, come on, come on!" "Kari:" "Come on!" "[ Laughs ]" "Here it comes!" "Headed straight for the pier." "[ Laughter ]" "What the heck?" "!" "We just took the pillar down!" "That was the wrong thing to split." "[ Laughing ] The marker just got split." "[ Laughter ]" "I didn't see that one coming." "I didn't, either." "I didn't see that coming, either." "That's not how it happened in the myth." "[ Laughs ]" "That's a good shot, though." "It hit it right on the bow." "[ Normal voice ] It did not split the boat in half." "That is the most important thing." "That's the important thing." "Narrator:" "Important because in that shocking, split-second impact, the tables on this myth turned." "The marker bifurcated, and the mythity split refused to live up to its name once again." "Grant:" "So, the whole reason for this revisit is that fans said that without water, our original tests were invalid." "You know what?" "They were right." "See, the resistance of the water kept the boat going straight on impact without glancing off." "However, the energy of the impact caused the pole to break and not the boat." "So ultimately, it's the same result... a busted myth." "Just a slightly different way of getting there." "Tory:" "Now, they say that two of the happiest days of a boat owner's life is the day he buys the boat and the day he sells it." "But I won't be happy until we cut that boat in half." "Narrator:" "Yep." "It ain't over until the mythity split splits." "...one." "Can you paint a room with a boom?" "Well, after a little trial and error..." "Looks like I need a little bit more work on my nozzle." "...each of the MythBusters have come up with a plan to find out." "Down at the range, it's time to test the state of their art." "I don't know what Adam's been up to, but I've had my hands full building my paint bomb, and I didn't have time to build a room to paint." "So, we brought in a team of carpenters, and they put this" "8-foot-high-by-12-foot-square room together as our blank canvas." "Narrator:" "The canvas is primed." "Here we go." "But strangely," "Adam's not unloading his device anywhere near it." "Allow me to introduce the snowflake, my painting machine." "It is named after both its hexagonal design and its uniqueness." "And its design is informed by exactly what I learned out here on the bomb range earlier this week." "And this is the result." "Some might feel like" "I have broken the rules with this design." "Narrator:" "Clearly, Adam's up to something." "All right." "Good." "And as he welds the final touches to the snowflake," "Jamie's confused." "I'm guessing the paint goes in the middle." "Yep, right along with the explosives." "So these things are in the way." "What?" "Are they supposed to disperse the paint or something?" "Nope." "These panels are exactly where I want them to be." "Well, how are you gonna paint the house?" "I'm not gonna paint the house." "I'm going to paint art that goes in the house." "Oh." ""Paintings" with explosives." "Yeah." "I thought I'm the one that's supposed to cheat." "Yeah, I thought I'd steal your thunder this time." "Usually, it's the underhanded Hyneman who decides to bend the rules..." "Hey, hey!" "[ Laughs ] ...and stack the odds in his favor." " But after 10 years..." " And that's for you." "...clearly, all that devious designing has rubbed off on Adam." "[ Adam laughs ]" "Well, this all started when I was out here at the bomb range doing my preliminary tests with painting and explosives." "I really, really liked the patterns that I was getting on my target board." "And I thought, "what if we made art?"" "I'm still technically "painting" with explosives." "I just figured Jamie was gonna go whole hog on getting that room covered with paint, and I could kind of do my own thing." "And that's what I did." "Narrator:" "Now it's time for the snowflake to make its kinetic art debut with six marbles of C-4 and some paint." "[ Chuckles ]" "I call this my psychedelic spring." "I'm ready to go." "Let's get to safety." "All right." "[ Siren blares ] You ready, sir?" " I'm ready." " All right." "Here we go." "[ British accent ] Painting with explosives to make some art in three, two, one." "[ Normal voice ] Wow, that was quick." "[ Laughs ]" "Narrator:" "It was quick." "But when you slow the explosion to 1,000 frames per second..." "Adam:" "Wow." "That is insane." "...It's also beautiful." "That's a piece of art in and of itself." "Look!" "It's like a clown's head exploded." "[ Chuckling ] That is the loveliest thing" "I have ever seen." "Narrator:" "But did that explosive pop of color create pop art?" "[ Laughs ]" "That's beautiful!" "All right." "There's one." "Oh." "Oh, it's gorgeous!" "That's beautiful." "The tale of destruction wreaked on the canvas." "Narrator:" "As Adam canvasses his canvases..." "Oh, yeah." "That's really nice." "...It's clear that all six were mostly covered with paint." "Well, I don't know much about art, but I know I like making it with explosives." "Hey, well, two of them have some nice colors going." "They show some promise." "Maybe... maybe you could take an art class or something." "[ Laughs ] What do you think?" "I'm very pleased." "I'm very pleased." "But while the results of Adam's art deco are a little muddy, it's the process that was beautiful." "Nice." "Can't wait to see what Jamie comes up with." "Top that, Hyneman." "Next, will a rocket sled close the case on this unsolved myth-tery?" "Tory:" "This is it, man." "Hopefully, we can cut this boat in half." "And can Jamie's paint ball deck the wall?" "[ Laughs ] I'd like to watch this one from the bunker." "Do not try what you are about to see at home." "We're what you call experts." "Tory:" "Rocket-sled track." "[ Sighs ]" "You guys ready for this?" "If there's one thing I like, it's fast." "Let's do it." "Grant:" "When we want to fly a wall down a track and pulverize a car, when we want to cause a rear-end collision at nearly 400 miles an hour..." "[ Laughing ] That was one of the coolest things I've ever seen!" "...we come here because, "A," there's no one around to get in harm's way, and, "B," nobody does extreme like our friends at new Mexico Tech." "And today is gonna be no exception." "So, why are we taking it to these extremes and using a rocket-powered sled?" "Well, we tested the myth just like it stated, crashing a boat at 25 miles an hour into a channel marker, but we couldn't get it to split in half." "So, the myth is busted." "But now it's my favorite part of the show, where we replicate the results." "Now, if it's worth doing, it's worth overdoing, and I would have to say this is overdoing." "Kari:" "Now, this is the boat that we're going to use." "It's not the exact same boat as the one in the myth, but it's gonna do just fine." "It will be weighted the same." "It's made of the same materials." "And the center of the bow is still hitting the center of the pole." "There's only one difference." "Narrator:" "Yep, and the reason for that difference is very familiar to the MythBusters." "Grant:" "Cable broke." "[Bleep]" "And inside NMT's high-tech classroom..." "Hey, Van." "Welcome back." "...Van Romero has the solution." "Flying the boat down a track is a little tricky." "Getting a boat to go 100, 150 miles an hour... what's gonna happen with a fast acceleration is it's probably gonna fly apart." "But we do have another option." "Instead of moving the boat down the track, let's look at moving the piling down the track." "Awesome." "If we do that, we can accelerate this pipe as fast as we want." "We won't have any problems." "The physics is identical as long as we get the closing speed to match the closing speed that we want." "Narrator:" "The roles will be reversed, and the pylon will hit the boat traveling at the top speed of a speedboat." "So, it's time to trek back to the track and prepare the sled." "Grant:" "The first thing you'll probably notice about the pole is unlike our previous experiment, it's metal instead of wood." "The reason for this is that at the speeds we're talking about, wood would simply shatter, where we know the metal's not gonna shatter." "The more important thing is the sheer amount of kinetic energy it's gonna generate." "The pole plus the sled weighs almost 600 pounds." "It's gonna be traveling at nearly 200 miles per hour." "See, the key to any good rocket-sled experiment... lubrication." "That's the kind of kinetic energy we need to give this boat split a fighting chance." "Narrator:" "But first, the marker needs a maritime makeover." "So, we're out here in the middle of New Mexico." "There's not a lot of ocean around, so..." "[ Seagull honking ]" "We decided to make it more marine-like." "So, we brought a seagull." "[ Seagull honking ]" "Is that the most irritating thing you've ever heard?" "Narrator:" "With the pole sitting pretty..." "[ Honking continues ] Kari:" "Aww." "...It's the boat's turn to get nautical." "Ocean spray." "We're going to add a little water to this boat just to keep the fans happy." "They really like "bifurcated boat" to be on water." "With the mythity split 3 in commission, they hoist the sails." "So, it's floating on air." "Well, there's something you don't see every day." "The boat's in place." "Now it's time to load up the sled with rockets and see if we can split this boat in half." "Three, two, one!" "Narrator:" "Devious Adam moved the goal posts..." "Adam:" "Wow, that was quick." "...and created art with explosives." "That's beautiful!" "But now it's the Hyneman's turn to paint and detonate." "[ Ominous music plays ] You need that." "I do." "It's time to load it up." "The myth requires 100% wall coverage, so Jamie's reducing his boom." "On our first test, we used C-4, which is a very fast, high explosive." "This time, we've slowed it down to about 1/4 or 1/5 of that speed with ditching dynamite." "This stuff goes off at about 5,000 feet per second, and I'm hoping that it'll have a lot more push with it." "Narrator:" "Maybe it'll push some paint." "But will it impress Adam?" "No fricking way." "What... how... this looks like it weighs 6,000 pounds." "Oh, it's only 3,500 or so." "[ Laughs ]" "Oh, my God." "How... how does this work?" "Well [Sighs] you put the top on, and you bolt it down." "You pour paint in, it fills up, the dynamite goes off, and it shoots paint out through the jets." "[ Laughs ]" "If it's okay with you," "I'd like to watch this one from the bunker." "Yeah." "This is... you know, this is a dangerous thing." "It is a beautiful thing." "[ Metal clangs ] [ Laughs ] Nice work." "And with the dynamite in position," "Jamie's planning to paint the town red." "Jamie:" "Who knows what the right paint thickness will be for this particular spray-paint job." "I mean, normally, you thin paint a little bit when you put it in a sprayer, so I figure this wouldn't be any different." "And in any case, the thinner the paint, the more it's gonna break apart when it's sprayed." "And why not hedge my bet?" "Narrator:" "Well, with the paint payload on board, the sphere is locked and loaded." "Congratulations." "After all these years, you finally made the death star." "[ Sighs ]" "Well, let's get out of here before it is actually the death star." "The circle is now complete." "So it's time to return to base and use the force." "[ Siren blares ] But can it paint an entire room?" "Okay." "Painting with explosives, the paint ball, in three, two, one, go." "Adam:" "What happened?" " Let's go check it out." " All right." "Wow." "[ Laughs ]" "That, uh, wasn't exactly what I had in mind." "But, um..." "You've made a four-wall rorschach test." "[ Laughs ]" "[ British accent ] Jamie, what do you see when you look at this blot?" "I see Valentine's day." "Valentine's day?" "Well, that's not the..." "Wow." "That's quite romantic of you." "Who knew?" "The death ball sprayed a red mist over the walls, but it looks less solid color and more Hollywood horror." "All that work, and this is what we get." "Well, it's food for thought, isn't it?" "[ Laughs ]" "And even though he didn't coat all of the walls," "Jamie's not disappointed." "Well, I'm tickled pink that my ball actually withstood the high explosive." "That was the main thing that I was worried about." "And the paint actually came out the jets quite nicely." "They did what they were supposed to." "They directed the paint at the walls, and you can even see that the jets were starting to shape the spray the way that I wanted to so that it didn't end up all right in the middle." "But as far as painting a house with explosives..." "It needs a little work." "[ Normal voice ] Final analysis, painting with explosives..." "what do you think?" "Well, we made some fine art today, but as far as painting houses, it's just not practical." "No, it's not gonna replace house painters anytime soon." "Got to be busted." "Let's go home." "[ Laughs ]" "It would actually be kind of nice to be able to paint your house in a millisecond, wouldn't it?" "Narrator:" "After the break..." "After seven years of waiting to find out if we could actually bifurcate a boat, we're ready to go." "Narrator:" "Meanwhile, at a gallery somewhere in San Francisco..." "[ British accent ] What are my bomb paintings about?" "Well, I mean, they're really about the universal themes of art, the explosive moment of inspiration, the randomness of our creation, the marks of detritus we leave on others' lives." "But mostly it's just 'cause I like to blow [Bleep] up." "Yeah." "Narrator:" "Deep in New Mexico, things are about to get fast." "So, I heard you got some rockets for us." "[ Deep voice ] This is the most dangerous part of our day... loading the rockets onto the sled." "[ Laughs maniacally ]" "Narrator:" "It's dangerous all right." "In fact, it's so dangerous, it requires a costume change." "This is an incredibly tense moment, and the reason is that the rockets have their igniters pre-installed." "So, just by handling them, they could ignite, and that would be a very, very bad thing." "And the other thing that makes it difficult is that the ignition level is not very high, one volt at one amp." "When you just walk around in wool clothing, you could generate a static charge of upwards of 40,000 volts." "So, that's why we have to remove anything that's not cotton and ground ourselves because we don't want these things going off." "Narrator:" "Yep, they're staying grounded 'cause the power of these rockets could knock more than their socks off." "To send this pylon down the track at 200 miles an hour, we are using vintage, Korean-war, high-velocity aircraft motors." "That's gonna give us the 200 miles an hour we need, 375 G's, and 12,000 pounds of thrust." "It's gonna annihilate the mythity split 3." "Narrator:" "Indeed." "That pylon will be traveling at the maximum speed a super-fast speedboat can go, which means there's no margin for error." "To the bunker." "[ Grant laughs ]" "Okay." "So, our high-speed cameras are in place." "We are ready to go." "This is the moment of truth." "What do I think is gonna happen?" "Look, that's a fiberglass boat." "It's a steel pole coming at it." "That thing is gonna shatter into a million pieces." "Mark my words." "Narrator:" "Well, where the curse of the bifurcated boat is involved, nothing is certain." "But they've cleared the decks." "All right, the pylon is loaded and hot." "We've got our boat in place." "Batten down the hatches." "Tory: [ Normal voice ] This is it, man." "Finally, hopefully, we can cut this boat in half." "[ Siren blares ] And now it's full steam ahead." "All right." "Rocket-sled pylon versus boat." "Three, two, one." "Yeah!" "[ Laughs ]" "Wow!" "We got bifurcation!" "It cut right down the middle!" "We did it finally!" "Ha-ha!" "Awesome!" "That was awesome." "Narrator:" "Yep, it seems the curse has lifted, and they finally split the boat." "Finally!" "After all this time, we bifurcated a boat." "But you know what that shows me?" "That dude had to be going fast." " Real fast." " Yep." "Let's go check out the carnage." "All right." "Narrator:" "Outside, it's clear that this ship is wrecked." "[ Laughs ]" "I cannot tell you how happy I am that this boat is finally split." "It split in two." "I mean, it's annihilated, but there is a clear division." "[ Imitates explosion ]" "The rocket sled does not disappoint." "Narrator:" "It does not." "Reaching 200 miles per hour in only 200 feet, the rocket-powered pylon plowed into the prow, tossing the boat into the air and leaving two halves in its wake." "Grant:" "All right, so, my prediction was that when the channel marker hit the boat, it would shatter into a million pieces." "But as you can see here, it actually tore a hole almost all the way down the hull, leaving this in two pretty-much-intact halves." "I've never been happier to say that I was wrong." "And it just goes to show that even a blunt object like our channel marker could turn into a knife when you add enough speed." "Kari:" "There's no way that guy was going 25 miles an hour." "We tried it over and over at 25." "We tried it off water, on water." "It took 200 before it started to split it." "We didn't even get a dent at 25." "I think he might have been lying." "Tory: [ Deep voice ] Seven years in the making, four channel markers, three boats, a barge, and a crane, but nothing could bifurcate the boat until now..." "With a rocket-powered sled." "But it looks like this one's still busted." "That was fun." "What do you think we could put on the rocket sled next?" " I don't know." " Maybe a bus." "Uhhh."
