1 00:00:00,000 --> 00:00:04,080 Remember do not try anything you are about to see at home 2 00:00:09,120 --> 00:00:11,280 On this episode of mythbusters 3 00:00:12,200 --> 00:00:15,800 Adam and Jamie get feisty with a bar fight fable 4 00:00:19,840 --> 00:00:24,360 Want to know if an empty beer bottle really does more damage than a full one 5 00:00:25,120 --> 00:00:27,120 God 6 00:00:28,720 --> 00:00:35,760 Meanwhile you have to massage the leather makes a better cannon in a ballistic material mystery from history 7 00:00:36,720 --> 00:00:43,600 These are the legs were Carrie Grant and Tori take on the tall tail of the Swedish and Irish cannons 8 00:00:46,600 --> 00:00:48,600 Made from leather 9 00:00:49,160 --> 00:00:55,520 Are the mythbusters Adam Savage comes chaos 10 00:00:56,200 --> 00:01:03,520 And Jamie Hyneman, I call him my little pop gun between them more than 30 years of special effects experience 11 00:01:04,280 --> 00:01:05,760 joining them 12 00:01:05,760 --> 00:01:07,760 Carrie Byron explosives in electricity 13 00:01:09,600 --> 00:01:16,880 Tori Bellachy is your bitch it's at Grant imahara now for something completely gratuitous. They don't just tell the kids 14 00:01:17,480 --> 00:01:19,480 They put them to the test 15 00:01:31,800 --> 00:01:37,040 We're not gonna have to start drinking in the middle of the day again, are we luckily no this is not a myth about 16 00:01:37,280 --> 00:01:42,560 Getting drunk it's a myth about what happens after you've already gotten drunk and gotten yourself into a bar fight 17 00:01:42,560 --> 00:01:48,800 And the myth is that getting hit with an empty bottle is worse for you than getting hit with a bottle 18 00:01:48,800 --> 00:01:50,800 That's full allow me to demonstrate 19 00:01:56,840 --> 00:02:01,040 No silver screen bar fight scene is complete without one 20 00:02:02,120 --> 00:02:08,200 However unlike the movies in real life a bottle bash is extremely dangerous 21 00:02:08,520 --> 00:02:16,040 How dangerous well award-winning forensic scientists list skull fractures 22 00:02:17,360 --> 00:02:19,600 Concussions and scalp lacerations 23 00:02:21,440 --> 00:02:23,440 Among the possible injuries 24 00:02:24,160 --> 00:02:28,560 They also conclude that an empty bottle smash will do more damage 25 00:02:28,680 --> 00:02:35,600 But is this really possible could a lighter empty bottle really harm you more than a heavier full one 26 00:02:36,480 --> 00:02:39,000 So how do you want to test this one? 27 00:02:41,600 --> 00:02:47,480 Fake bottle don't do this at home. No seriously. How are you thinking we should test this exactly like that? 28 00:02:47,480 --> 00:02:54,680 But with real bottles except with head protection. We'll have a closer look at what kind of forces are involved, okay? 29 00:02:58,160 --> 00:03:00,280 So let the bar fight come ends 30 00:03:01,280 --> 00:03:06,600 Even though after a few beers it might seem like a good idea to hit somebody over the head with a beer bottle 31 00:03:06,640 --> 00:03:08,560 It's probably not 32 00:03:08,560 --> 00:03:14,680 Nevertheless, we feel inclined to get up close and personal on our testing and that's where this comes in 33 00:03:14,680 --> 00:03:20,760 This is a football helmet outfitted with a specially designed array of accelerometers that will register 34 00:03:20,840 --> 00:03:26,840 Any movement of our skull and help us determine whether a full versus an empty beer bottle is more harmful 35 00:03:27,520 --> 00:03:33,040 Plus it's a nice excuse for me to hit at him over the head with a bottle which I regularly want to do 36 00:03:33,680 --> 00:03:35,080 You ready? 37 00:03:35,080 --> 00:03:37,840 You know before I put this on and take some hits to the head 38 00:03:37,840 --> 00:03:43,840 Let's put this on a non-human analog just to make sure it's safe see what kind of forces are involved, okay? 39 00:03:47,640 --> 00:03:54,040 It's ready. I'm ready. We're ready. Okay safety systems check 40 00:03:57,080 --> 00:03:59,080 Wow 41 00:03:59,720 --> 00:04:01,720 That's not what happens in the movies 42 00:04:03,040 --> 00:04:05,440 Now it seems like these are a lot harder to break than we thought 43 00:04:07,120 --> 00:04:09,240 And I think that's because of a couple of vain reasons 44 00:04:09,240 --> 00:04:13,080 What's the matter old man been too long since your last bar fight one is in the movies 45 00:04:13,080 --> 00:04:17,280 You're always seeing people smack each other over the head with bottles and the bottles break really easily 46 00:04:17,280 --> 00:04:23,520 Well, those are fake bottles. It's the movies and number two who among us hasn't dropped in broken bottles 47 00:04:23,520 --> 00:04:27,800 They seem quite fragile. The fact is they're not they're actually built to ship 48 00:04:27,840 --> 00:04:30,640 They're built to last and when you look at shots like this 49 00:04:31,360 --> 00:04:33,360 this and this 50 00:04:34,440 --> 00:04:37,460 It's pretty clear these things are tougher than they look 51 00:04:38,040 --> 00:04:44,920 Adam however is as tough as he looks out. Not very so when our expert crunches the numbers 52 00:04:44,920 --> 00:04:46,920 I was about a hundred and seven G's 53 00:04:47,760 --> 00:04:50,640 the experiment takes a safer turn and 54 00:04:51,080 --> 00:04:54,980 About a hundred G's is the average concussion that we see in the field. I 55 00:04:55,800 --> 00:04:59,040 Don't think I'm gonna be wearing that helmet today. I don't blame you 56 00:05:00,760 --> 00:05:05,160 The helmet doing what it was designed to do was flexing on impact 57 00:05:05,680 --> 00:05:09,240 absorbing energy and making it difficult to break the bottle 58 00:05:09,880 --> 00:05:14,880 Q our hard-headed head stuntman with his crown of data collecting 59 00:05:15,680 --> 00:05:17,680 accelerometers 60 00:05:18,600 --> 00:05:19,960 Oh 61 00:05:19,960 --> 00:05:28,520 There you go. Did you get a reading? Yeah, it's about 54 G's awesome awesome, but one data point does not a sample make 62 00:05:30,480 --> 00:05:33,360 So in a frenzy of beer and broken glass 63 00:05:34,280 --> 00:05:36,080 33 hard man 64 00:05:36,080 --> 00:05:36,880 Heinemann's 65 00:05:36,880 --> 00:05:42,480 Smashes away 11 G's until he satisfied with a sample set of seven 66 00:05:43,880 --> 00:05:47,640 34 which yields an average of 28 G's 67 00:05:48,440 --> 00:05:56,400 Awesome, let's continue with an empty bottle remember the myth is that an empty bottle when smashed is more damaging than the full 68 00:05:56,400 --> 00:05:58,600 Are you peeing? No, okay? 69 00:05:59,720 --> 00:06:01,800 It's the comparison that's the key 70 00:06:04,000 --> 00:06:06,480 Okay, here we go empty beer bottle 71 00:06:07,600 --> 00:06:12,880 And as the numbers come in it's clear that comparison does not favor the myth 72 00:06:13,880 --> 00:06:15,880 13 G's 73 00:06:16,880 --> 00:06:24,920 So it's about 11 G's less G force to the head from the empties appears to indicate they do less damage than the full ones 74 00:06:25,840 --> 00:06:29,240 But Adams got an issue with the experimental design 75 00:06:29,880 --> 00:06:35,080 In general the data seems to support the idea that it's not looking very good for the myth 76 00:06:35,080 --> 00:06:40,280 But we're seeing huge variances in the G load on this guy depending on how hard Jamie swings 77 00:06:40,280 --> 00:06:43,160 Which is very hard to control clearly moving forward 78 00:06:43,160 --> 00:06:49,680 We're going to need to remove the variance of the human arm and go with a mechanical solution to solving this problem 79 00:06:57,320 --> 00:07:01,760 All right, Carrie what do these things have in common? 80 00:07:02,040 --> 00:07:09,480 Okay, creamer cheese leather chicken duct tape and a steel pipe Saturday night at Adams avidges house very close 81 00:07:09,480 --> 00:07:11,080 No 82 00:07:11,080 --> 00:07:16,520 Saturday night at Jamie Heinemann's house. No cannon. Okay, get everything but the leather. Well, that's the next myth 83 00:07:16,520 --> 00:07:19,160 We are gonna try to build a cannon out of nothing but leather 84 00:07:19,880 --> 00:07:21,560 Okay, really? 85 00:07:21,560 --> 00:07:26,520 Absolutely in the 17th century King Gustavus Adolphus of Sweden came up with the idea 86 00:07:26,520 --> 00:07:29,600 It was a copper core with iron bands reinforcing it 87 00:07:29,880 --> 00:07:34,880 Massive soap fabric and finally the entire thing was wrapped in leather. That's not a leather cannon 88 00:07:34,880 --> 00:07:39,840 That's a cannon covered in leather. But wait, there's more later that century at the siege of Balli Nali castle 89 00:07:40,080 --> 00:07:46,960 Irish troops actually built a cannon using nothing but leather. It was about five feet long and about five inches thick leather cannon 90 00:07:46,960 --> 00:07:48,960 I like it 91 00:07:49,120 --> 00:07:53,800 The mythbusters and cannons have a long and explosive history 92 00:07:54,680 --> 00:07:59,320 I think we killed captain Kirk. There was a cheese firing cannon a 93 00:07:59,960 --> 00:08:06,200 Cannon made from duct tape and not to mention the famous cannon that fired chicken 94 00:08:08,120 --> 00:08:13,960 So who better to get to the bottom of this mystery of history did the Swedes and Irish 95 00:08:14,200 --> 00:08:18,320 Really make a viable and effective cannon from cow skin 96 00:08:20,560 --> 00:08:22,720 So my leather man, what's the plan? 97 00:08:22,840 --> 00:08:27,520 Well, we definitely need to build both versions Swedish and Irish but before we do that 98 00:08:27,520 --> 00:08:32,600 I think we need a benchmark. What do you mean? Well, we've built proof of concept cannons before like the duct tape cannon 99 00:08:32,600 --> 00:08:36,600 But those weren't weapons of war. I mean we need something that can compete on the battlefield 100 00:08:36,600 --> 00:08:39,840 So we need to compare it to a cast iron period cannon 101 00:08:40,040 --> 00:08:44,120 Exactly, we'll find out how much black powder they use and how fast the projectiles come out 102 00:08:44,120 --> 00:08:47,760 Yeah, and on those specs we'll be able to judge how well our two cannons are doing 103 00:08:47,760 --> 00:08:48,920 I like it 104 00:08:48,920 --> 00:08:57,240 So first up it's down to the bomb range to get the lowdown on period accurate hardware from period accurate experts 105 00:08:57,900 --> 00:09:04,320 Haha, this is Bonnie blue the Confederates tended to name their cannon. Yeah, we have a tendency to do that too 106 00:09:04,320 --> 00:09:06,320 Let's get her off the truck and fire it up 107 00:09:07,240 --> 00:09:09,480 We're at the Alameda County bomb range 108 00:09:09,480 --> 00:09:13,520 We're about to fire off a civil war period cannon known as the parrot gun 109 00:09:14,960 --> 00:09:22,640 Now the myth that we're working on says that the Irish and the Swedish created a leather cannon now this cannon's approximately the same size and 110 00:09:22,760 --> 00:09:26,480 Fires approximately the same size ammunition as the leather cannon 111 00:09:26,680 --> 00:09:29,080 You know it's go time with grants got his game face on 112 00:09:30,080 --> 00:09:32,080 It's go time 113 00:09:32,280 --> 00:09:38,920 So we're going to fire this off check the muzzle velocity and use that as a yardstick against the ones that we want to build 114 00:09:38,920 --> 00:09:45,000 We have perfect if this doesn't stop cannonball. I don't know what will have a stack of Union soldiers 115 00:09:45,920 --> 00:09:51,760 Meanwhile Grant is getting set up to measure what old Bonnie blue can do as you know on our show 116 00:09:51,760 --> 00:09:57,840 We'd love to use the high-speed camera because it gives us all these juicy gorgeous shots things that happen in a blink of an eye 117 00:10:03,160 --> 00:10:05,320 But today it's going to be a scientific tool 118 00:10:08,600 --> 00:10:12,520 So we've aimed the high-speed camera at this scale which is set up next to the cannon 119 00:10:12,520 --> 00:10:15,720 It has one foot increments given a known frame rate 120 00:10:15,720 --> 00:10:20,120 We can count how many frames it takes for a cannonball to cross one of the increments 121 00:10:20,120 --> 00:10:26,240 That would give us a cannonball speed which will form the benchmark for how well our Swedish and Irish cannons perform 122 00:10:27,520 --> 00:10:32,320 Okay, let's talk black powder firing off the cheese cannon, maybe this much black powder 123 00:10:35,160 --> 00:10:37,160 Duck tape cannon maybe this much 124 00:10:39,120 --> 00:10:41,800 And when we blew off Buster's leg maybe that much 125 00:10:42,440 --> 00:10:52,760 This is six ounces of black powder that is what we'll be firing in our paired gun gun is loaded 126 00:10:53,360 --> 00:10:55,820 Alright muzzle velocity test on your go 127 00:11:12,320 --> 00:11:14,320 Nice shot 128 00:11:14,680 --> 00:11:18,960 So the whole point of today's experiment is not to find out whether that cannon fire we know it does 129 00:11:20,320 --> 00:11:28,800 Point find out how fast a real cannon could fire a cannonball the same size that the Swedish and Irish leather cannons were supposed to have fired 130 00:11:29,000 --> 00:11:31,000 Okay, I believe we have 131 00:11:31,720 --> 00:11:34,360 389 miles per hour and we have that answer 132 00:11:35,520 --> 00:11:37,520 389 miles per hour 133 00:11:37,520 --> 00:11:45,740 So that's the benchmark if the team can get their mythical leather cannon to fire that fast there could be some fact to this 134 00:11:46,320 --> 00:11:48,320 historical fable 135 00:11:48,680 --> 00:11:50,680 Next on myth Buster's 136 00:11:51,560 --> 00:11:53,560 Adam packs up porky punch 137 00:11:59,120 --> 00:12:05,080 So where do we stand with the bottle bash well sadly we weren't able to bash each other over the heads with bottles 138 00:12:05,480 --> 00:12:08,520 We had to settle for this guy and what did he have to tell us? 139 00:12:09,800 --> 00:12:13,840 Yes, that the full bottle somehow imparted more force than the empty bottle 140 00:12:15,160 --> 00:12:21,440 Which contradicts the myth right which is that somehow the empty bottle is worse for you and given that I can't precisely 141 00:12:21,680 --> 00:12:28,040 Control exactly how hard I hit it's impossible to know whether it's the bottle or my hit that is causing a result 142 00:12:28,120 --> 00:12:34,760 So what we need then is some kind of mechanical bottle bashing rig and a setup that helps us compare the injuries 143 00:12:34,760 --> 00:12:40,960 It's like a bar fight robot. Okay. Well you get started on that and I'll go talk to the neuro guy and see what kind of 144 00:12:41,280 --> 00:12:43,680 Injuries we're looking for on heads. Okay 145 00:12:45,560 --> 00:12:50,260 So while Adam builds a rig to bash brains with rigorous regularity 146 00:12:52,680 --> 00:13:00,760 Jamie talks to a bashed brain expert. So what exactly happens in a concussion a concussion is when you transfer a force 147 00:13:01,600 --> 00:13:08,520 External through the skull to the brain think of the skull is a box and you've got the brain inside that has the consistency of Jello 148 00:13:08,720 --> 00:13:14,080 This is your brain. I'm about to turn it into a Jello mold. Here we go 149 00:13:16,040 --> 00:13:18,040 There we go one 150 00:13:18,280 --> 00:13:25,080 gelatin brain mold when a concussion occurs and forces delivered to the skull itself the skull moves relative to the brain 151 00:13:25,080 --> 00:13:29,280 Brain stays in one place the skull moves against it that can bruise the brain 152 00:13:29,280 --> 00:13:33,440 It's hitting the skull and it can actually damage the brain opposite that oh 153 00:13:35,240 --> 00:13:40,560 What am I doing? I'm making gelatin brains. What are you doing? 154 00:13:41,160 --> 00:13:43,160 It's all a function of force Jamie 155 00:13:43,160 --> 00:13:49,760 It's how much energy is transmitted to the skull and to the brain that determines how severe the concussion is or how much 156 00:13:49,760 --> 00:13:51,760 Injury there is to the brain 157 00:13:51,760 --> 00:13:53,040 Go 158 00:13:53,040 --> 00:13:55,040 That's what I'm thinking 159 00:13:55,480 --> 00:14:01,680 It sounds like the bottom line is that whatever kind of blow moves the head more violently is what's gonna cause more of a concussion, right? 160 00:14:02,480 --> 00:14:03,560 Absolutely 161 00:14:03,560 --> 00:14:04,120 All right 162 00:14:04,120 --> 00:14:11,160 The whole purpose of this rig is to precisely and at the same speed every time swing a beer bottle into our model head to see if 163 00:14:11,160 --> 00:14:16,680 We get a concussion or how bad a concussion we get so first the arm is held in tension by this spring 164 00:14:16,680 --> 00:14:21,000 The vice grip here holds on to the beer until it swings into the head 165 00:14:21,000 --> 00:14:24,920 So we release the pin the arm swings around all the way to the head 166 00:14:24,920 --> 00:14:32,080 Here's the head on the neck weighing roughly about the same as a human head hold on. Let me add the piece through his stones a 167 00:14:33,440 --> 00:14:36,920 Nice gelatin brain now we'll watch this on high speed 168 00:14:36,920 --> 00:14:42,720 We'll see the brain bounce around and if we can see a difference in how much the head moves and the brain bounces around 169 00:14:42,720 --> 00:14:47,200 We might be able to tell something about the kind of concussion you'll get when someone breaks a bottle over your head 170 00:14:47,800 --> 00:14:56,120 But before the brain bashing begins Adam needs to know exactly how fast he needs to swing his bottles to ensure they break 171 00:14:56,400 --> 00:15:00,000 for that he's got a smaller version of the rig and a 172 00:15:00,640 --> 00:15:02,480 pig 173 00:15:02,480 --> 00:15:03,840 Here's the experimental setup 174 00:15:03,840 --> 00:15:07,920 I'm gonna take these bottles and thwack this pig right in the brain until they shatter 175 00:15:08,200 --> 00:15:15,120 This arrow right here and the high-speed camera above it will tell me the exact speed at which these bottles shatter both full and empty 176 00:15:15,280 --> 00:15:20,640 This is gross science in action in three two one 177 00:15:27,000 --> 00:15:28,760 Awesome 178 00:15:28,760 --> 00:15:34,960 Gross but awesome. It's a horror movie. All right, but throughout the violence of the hams 179 00:15:36,160 --> 00:15:38,040 This is for the money right here. All right 180 00:15:41,040 --> 00:15:43,040 Adam gets enough hits 181 00:15:44,040 --> 00:15:47,520 That has to hurt with full and empty bottles 182 00:15:48,240 --> 00:15:49,520 success 183 00:15:49,520 --> 00:15:54,240 To get a good idea of the speed they need for a guaranteed smash 184 00:15:55,840 --> 00:16:00,520 And that speed turns out to be about 50 feet per second or 34 miles per hour 185 00:16:01,240 --> 00:16:07,640 So now that they can calibrate the big rig swing speed Jell-O head is ready to take one for the team 186 00:16:13,680 --> 00:16:23,040 Carrie Grant and Tory are delving deep into ballistics history to uncover the mystery of two cannons made in a tannery 187 00:16:25,000 --> 00:16:31,800 We're trying to replicate two historical cannons both referred to as leather cannons the first one is the Swedish cannon 188 00:16:31,800 --> 00:16:37,440 It's got a copper core tube that's wrapped in some iron bands and some other stuff and basically has a leather veneer 189 00:16:37,440 --> 00:16:41,900 The second cannon is the Irish cannon this is from the early 1700s now 190 00:16:41,900 --> 00:16:47,520 This one is a more authentic leather cannon if you ask me this one's entirely made out of leather 191 00:16:47,960 --> 00:16:54,860 With the hide soak to make it more malleable. It's time to focus on the first of the builds guess which one it is 192 00:16:55,360 --> 00:16:58,480 The new dance is called directing traffic 193 00:17:00,600 --> 00:17:07,360 So here's how you build an authentic 17th century all-leather Irish cannon paint on the glue 194 00:17:07,960 --> 00:17:10,480 Insert a one-inch thick plug at the back end 195 00:17:11,720 --> 00:17:14,000 Roll the hide around a steel fork 196 00:17:14,960 --> 00:17:18,800 Hopefully this is gonna be strong enough to withstand 197 00:17:19,920 --> 00:17:21,480 Exploding black powder 198 00:17:21,480 --> 00:17:26,720 Laminate enough layers to ensure a one-inch thick barrel with a five-inch diameter 199 00:17:26,880 --> 00:17:31,080 Is it just me or does our bad-ass cannon look more like a hot dog? 200 00:17:31,200 --> 00:17:36,120 Tie it off and wait for it to dry. It's not the prettiest thing, but I think it'll work 201 00:17:36,880 --> 00:17:38,880 That's what they said when they hired me 202 00:17:40,840 --> 00:17:43,760 With the Irish cannon wrapped up and ready to blow 203 00:17:45,000 --> 00:17:51,360 Grant in a more culturally sensitive fashion than Tori is going to give us the background on the Swedish cannon 204 00:17:51,360 --> 00:17:55,280 Now in the 1600s in Europe everybody had pretty much the same design for cannon 205 00:17:56,120 --> 00:17:58,120 giant cast iron 206 00:17:58,320 --> 00:18:05,720 Unfortunately, these cannons work incredibly heavy and cumbersome and it took several men and several horses just to move them into position 207 00:18:06,640 --> 00:18:08,520 Long came the king of Sweden 208 00:18:08,520 --> 00:18:15,920 King Gustavus Adolphus II who had a brand new idea for an army an army that was incredibly mobile that could deploy quickly 209 00:18:16,240 --> 00:18:22,360 He threw out this idea of a cannon and came up with something that was lighter and more portable 210 00:18:24,000 --> 00:18:27,360 Now in truth there wasn't much leather in a Swedish leather cannon 211 00:18:27,360 --> 00:18:30,640 In fact, it had a thin wall copper tube for its barrel 212 00:18:31,080 --> 00:18:35,120 It's basic sawed-off leather cannon with a brass plug on the end 213 00:18:37,080 --> 00:18:42,600 That was covered with several layers of canvas soaked in mastic. What the heck is mastic? 214 00:18:42,600 --> 00:18:45,520 Well, it's a type of resin now we don't have mastic 215 00:18:45,520 --> 00:18:49,400 But what we do have is a two-part epoxy resin on top of that 216 00:18:49,800 --> 00:18:56,520 We're for iron bands to reinforce it then more canvas and mastic then paint another layer that way it gets embedded 217 00:18:56,560 --> 00:19:01,920 When it hardens it's gonna be very strong and finally on the top was leather 218 00:19:01,920 --> 00:19:06,840 That was called a leather cannon, but in fact it was a hybrid it had a metal barrel 219 00:19:06,960 --> 00:19:10,160 The important thing is that was lightweight and mobile 220 00:19:11,040 --> 00:19:15,440 Mobile you say well with these wheels they can roll on down to the bomb range 221 00:19:16,760 --> 00:19:21,960 Where we'll find out whether these mythical cannons built to spec could have really worked 222 00:19:22,920 --> 00:19:25,560 After the break Jello head is left dazed 223 00:19:27,080 --> 00:19:29,880 And lobotomized it's a delicious memory 224 00:19:32,520 --> 00:19:34,520 It's a 225 00:19:35,520 --> 00:19:42,240 Counter-intuitive conundrum forensic scientists tell us an empty beer bottle broken on your brain box 226 00:19:42,280 --> 00:19:45,720 Will cause more damage than a heavier full one 227 00:19:48,960 --> 00:19:54,880 Looking for answers Jamie and Adam are lining up Jello head for a comparative concussion test 228 00:19:55,600 --> 00:20:00,720 Okay, here we go one full beer bottle concussion test in three 229 00:20:01,160 --> 00:20:03,160 two one 230 00:20:08,120 --> 00:20:10,120 It looks great 231 00:20:10,320 --> 00:20:12,080 Seems to work 232 00:20:12,080 --> 00:20:14,580 Except it doesn't I look at the high speed 233 00:20:17,160 --> 00:20:25,000 Confirms the beer isn't clear problem is the beer is obstructing our ability to see the brain. Yeah, isn't that always the way? 234 00:20:25,240 --> 00:20:30,920 So the way to go is carbonated H2O 235 00:20:31,840 --> 00:20:37,680 We're ready. Let's do it full beer bottle cousin test three two one 236 00:20:42,400 --> 00:20:44,940 Didn't break high speed high speed 237 00:20:49,280 --> 00:20:52,400 Wow, that's a lot of force 238 00:20:53,400 --> 00:20:57,000 You see how the skull moves and then the brains in one place 239 00:20:57,080 --> 00:21:04,160 Yeah, it's the side of the skull on the front side and then look at that the brains going completely to the opposite 240 00:21:04,160 --> 00:21:09,240 Oh, wow, maybe the waves inside the Jello. That's what happens in real life 241 00:21:10,480 --> 00:21:18,560 The full bottle hit clearly falls into the not good category another wasted beer cue the empty bottle comparison 242 00:21:18,640 --> 00:21:20,640 Somewhere kittens are crying 243 00:21:22,400 --> 00:21:24,400 What do you think's gonna happen buddy? 244 00:21:29,680 --> 00:21:31,680 Really 245 00:21:32,880 --> 00:21:34,880 No, I never saw it that way before 246 00:21:37,080 --> 00:21:44,100 Okay, you ready for the empty bottle ready. All right empty bottle concussion test three two one 247 00:21:44,700 --> 00:21:46,700 I 248 00:21:48,340 --> 00:21:50,180 Don't even need to see the high speed 249 00:21:50,180 --> 00:21:52,860 I can tell by looking at the guy's face that he's messed up 250 00:21:53,260 --> 00:21:55,140 Sure, he's not a pretty sight 251 00:21:55,140 --> 00:22:01,580 But he's actually a lot better off than he was after the last test the lateral movement of the skull is 252 00:22:01,940 --> 00:22:08,000 Significantly reduced with the empty bottle was nowhere near the amount of head movement relative to brain 253 00:22:08,300 --> 00:22:12,980 So it is moving around but not near as much as it was with full bottle. Yeah 254 00:22:13,260 --> 00:22:16,720 Yeah, we're delivering less force with the empty bottle no question 255 00:22:17,740 --> 00:22:24,420 Awesome, that's like a result. Let's put the two up next to each other on the screen just like that. Okay now play 256 00:22:25,620 --> 00:22:29,780 Look at that. It couldn't be clearer. The full bottle is far worse 257 00:22:30,180 --> 00:22:37,940 That's another headache for this forensic science inspired myth so far Adam and Jamie have yet to see a sign 258 00:22:38,060 --> 00:22:42,140 That an empty bottle when smashed can cause more damage 259 00:22:42,340 --> 00:22:44,340 But they're not done yet 260 00:22:44,460 --> 00:22:50,180 The additional mass in a full bottle does seem to impart more energy to a target skull when it's broken over it 261 00:22:50,180 --> 00:22:52,180 And that could lead to a concussion 262 00:22:52,500 --> 00:22:59,260 But we're talking about head injury here and so that could also be skull fractures. It could be skin lacerations 263 00:22:59,700 --> 00:23:01,780 So we're gonna have a close look at those two 264 00:23:02,340 --> 00:23:06,700 But remember that time I built the machine to swing bottles of beer at your head 265 00:23:07,940 --> 00:23:11,060 No, you don't 266 00:23:12,340 --> 00:23:14,340 It's a delicious memory 267 00:23:14,540 --> 00:23:18,900 Coming up on myth busters. Can you really build a leather cannon that works? 268 00:23:21,380 --> 00:23:25,900 Don't try anything you see on the show at home. We're what you call experts 269 00:23:29,300 --> 00:23:33,040 All right, so here's where we're at so far we've tested out the parrot rifle 270 00:23:35,420 --> 00:23:37,700 Which is an all metal barrel cannon 271 00:23:37,940 --> 00:23:43,900 We found out how fast that can fire a cannonball 272 00:23:45,260 --> 00:23:52,780 389 miles per hour well now we're gonna do is test out the Swedish leather cannon in which most of the metal of the barrel has been 273 00:23:52,940 --> 00:23:55,420 Replaced by other materials to make it lighter 274 00:23:57,620 --> 00:24:02,220 Then we'll move on to the Irish leather cannon in which it's all leather 275 00:24:02,260 --> 00:24:06,260 All right, folks what I have here is six ounces of black powder 276 00:24:06,260 --> 00:24:11,300 This is what we're gonna be using to propel our cannonball now when we fired the paragon it was traveling at 277 00:24:11,900 --> 00:24:15,540 389 miles per hour that is fast the same amount of energy 278 00:24:15,540 --> 00:24:19,620 It would be like hitting a baseball going 1200 miles per hour folks 279 00:24:19,620 --> 00:24:27,540 This is something you do not want to play with so with a firm grip on the explosive potential involved and all of the technical jargon 280 00:24:27,540 --> 00:24:31,820 Okay, where's the pokey stick the team lock and load venting 281 00:24:32,820 --> 00:24:37,360 All right loaded, okay, I'm gonna go hot you ready. I'm ready 282 00:24:39,260 --> 00:24:44,300 This is Swedish cannon in three two one 283 00:24:49,500 --> 00:24:51,500 Look at that it was 284 00:24:52,100 --> 00:24:54,100 or did it 285 00:24:54,620 --> 00:24:59,660 Now we came out here some of us thought that this was going to shoot off like a cannon some of us thought it might explode 286 00:25:00,140 --> 00:25:02,140 Pretty much did both 287 00:25:05,260 --> 00:25:09,940 Look at this it just completely blew out the back 288 00:25:13,060 --> 00:25:19,740 One-shot wonder we actually had the cannonball shoot out of one end while the in bits shot out the other 289 00:25:20,460 --> 00:25:22,460 That's not looking too good 290 00:25:23,260 --> 00:25:29,260 But a quick assessment of the targets and the team are much more positive. Hey, it did the job 291 00:25:29,260 --> 00:25:35,100 Yeah, give it up for the Swedish cannon. It didn't make it through the sandbags, but it did make it through the second barrel 292 00:25:35,100 --> 00:25:39,260 And once the numbers are crunched it gets even more interesting 293 00:25:39,260 --> 00:25:45,100 So we tested our Swedish can the same size and weight cannonball the same amount of black powder and getting 294 00:25:46,100 --> 00:25:49,700 667 feet per second, which is over 450 miles an hour 295 00:25:49,820 --> 00:25:58,460 That's 50 miles an hour faster than our parrot gun what I've got to say its performance was equal to or a little bit better 296 00:25:58,740 --> 00:26:02,540 Than the all-metal cannon it had a muzzle velocity that was higher 297 00:26:03,060 --> 00:26:09,440 Maybe it was a tighter pack so that way it shot the ball faster. Who knows we only missed the x-pipe that much 298 00:26:09,820 --> 00:26:13,220 Minor problem. We blew out the breach, but bear in mind 299 00:26:13,340 --> 00:26:16,460 This was our first attempt to make this type of cannon 300 00:26:16,460 --> 00:26:22,540 I'm sure the Swedish didn't get right the first time so as far as a battlefield weapon the Swedish cannon had 301 00:26:22,860 --> 00:26:25,660 Superior maneuverability with very good accuracy 302 00:26:26,620 --> 00:26:31,620 Unfortunately longevity could be a problem and as it turns out historically it was 303 00:26:32,100 --> 00:26:38,460 So in the context of the parrot rifle performance benchmark the lightweight hybrid cannon matched up 304 00:26:38,980 --> 00:26:44,060 Which just leaves the Irish question wheels came off good sign 305 00:26:44,140 --> 00:26:47,020 So we've got six ounces of black powder right ready to load 306 00:26:47,380 --> 00:26:49,660 Black powder a three pound cannonball 307 00:26:50,420 --> 00:26:55,460 That's nice and tight and a barrel that's one inch thick of leather you got all that up 308 00:26:55,460 --> 00:27:03,060 I think you're gonna get boom. All right, everybody clear muzzle from now on this whole idea of building a cannon out of leather 309 00:27:03,060 --> 00:27:05,060 It's absurd run away 310 00:27:05,300 --> 00:27:09,100 Loaded but I mean if you're desperate and that's the only material you have available to you 311 00:27:09,100 --> 00:27:15,340 I guess sure why not try it, but I mean we know how powerful exploding black powder is what Irish leather cannon 312 00:27:15,340 --> 00:27:18,940 All right, this is Irish leather cannon ready the force is involved 313 00:27:18,940 --> 00:27:24,940 I mean is a one inch wall of leather gonna be enough to contain it in order to launch this cannonball 314 00:27:26,140 --> 00:27:31,980 I'm very curious to find out in three my feeling is it's probably not gonna work two 315 00:27:32,660 --> 00:27:34,660 one 316 00:27:39,420 --> 00:27:41,420 Nice 317 00:27:45,340 --> 00:27:47,340 Like 318 00:27:48,260 --> 00:27:51,960 It was more dangerous to be behind this cannon than in front of the camera 319 00:27:53,860 --> 00:27:58,020 Yep, it's pretty clear the Irish cannon failed on all counts 320 00:27:58,460 --> 00:28:05,300 The back end blew out and even with modern glue the barrel unraveled so the guys can't even try again 321 00:28:06,060 --> 00:28:12,300 And what we were looking for for this myth to be confirmed is very simple lethality say the Irish were fighting leprechauns 322 00:28:12,500 --> 00:28:14,500 It might be 323 00:28:16,060 --> 00:28:21,860 We tested the parrot rifle and the Swedish leather cannon and with the same size cannonball and same amount of gunpowder 324 00:28:21,900 --> 00:28:26,180 They were able to launch the ball at 350 to 450 miles per hour 325 00:28:26,700 --> 00:28:33,180 Now as far as the Irish leather cannon goes I can't call that lethal no with the best available information built to those 326 00:28:33,540 --> 00:28:38,260 Specifications this one is busted, but that does not mean we're gonna end here 327 00:28:38,260 --> 00:28:44,700 We are gonna see what it would take to build a working cannon out of nothing, but leather might not be possible 328 00:28:45,020 --> 00:28:49,260 But we're gonna try coming up Jamie brings meat head to life 329 00:28:49,820 --> 00:28:52,340 Before bashing his brain box with a beer bottle 330 00:28:57,220 --> 00:29:01,360 What Adam and Jamie have already seen that as far as concussions go 331 00:29:01,740 --> 00:29:06,740 Contrary to the myth a full bottle smash is worse for you than an empty 332 00:29:08,260 --> 00:29:12,580 But what about other types of head trauma? What about a skull fracture? 333 00:29:13,100 --> 00:29:18,820 To find out Jamie. That's what I'm talking about is taking a piece of pig skull 334 00:29:19,940 --> 00:29:25,220 7 millimeters same thickness as a human skull to calibrate and manufacture a 335 00:29:25,980 --> 00:29:31,140 polyurethane plastic that fractures in exactly the same way as a human skull 336 00:29:31,780 --> 00:29:36,500 Pulled from the pan while pliable. He forms it into shape before it hardens 337 00:29:37,420 --> 00:29:41,820 We've got the base and we've got this insert that goes over this cavity 338 00:29:41,820 --> 00:29:46,060 And when we hit it with a beer bottle like so if we get a fracture 339 00:29:46,500 --> 00:29:54,160 We know that we would have fracture a real skull to get a realistic mass Jamie adds a brain's weight of ground beef 340 00:29:54,160 --> 00:29:56,160 That's it six pounds 341 00:29:56,420 --> 00:30:00,500 Meanwhile Adam has built a bar for the soon-to-breakout bar fight 342 00:30:01,100 --> 00:30:04,700 Welcome to the myth busters bar. Can I interest you in an empty beer? 343 00:30:06,940 --> 00:30:12,940 Which means meat head with his inability to duck is about to get a headache 344 00:30:13,140 --> 00:30:18,500 Mr. Heineman says it's time to bash some heads in and chew some gum and he's fresh out of gum 345 00:30:19,460 --> 00:30:21,460 Take it away. Okay 346 00:30:21,740 --> 00:30:25,420 skull fracture rig and three two one 347 00:30:28,460 --> 00:30:30,460 All hell broke loose 348 00:30:30,460 --> 00:30:38,700 We got broken bottles we got broken head meat spilling out all over the place 349 00:30:39,140 --> 00:30:45,900 Adams no doctor, but broken head and meat spilling out is a fairly accurate diagnosis 350 00:30:47,780 --> 00:30:50,280 Man that is it's clearly 351 00:30:50,980 --> 00:30:56,260 Shattered the skull totally shattered the skull the rig worked. Yep meat head did us proud, huh? 352 00:30:56,260 --> 00:30:59,340 All we need now is to try this with an empty bottle. Yep 353 00:30:59,980 --> 00:31:01,580 More data 354 00:31:01,580 --> 00:31:07,940 More data with a side of sampling at a comparative observation salad coming right up 355 00:31:09,340 --> 00:31:15,020 Empty bottle of beer coming right up buddy. We're gonna do this at least one more time and if it's any consolation 356 00:31:15,700 --> 00:31:18,260 It's gonna hurt you a lot more than it's gonna hurt me 357 00:31:19,300 --> 00:31:25,420 When you're ready empty bottle into skull fracture rig three two one 358 00:31:25,980 --> 00:31:29,160 That's what I'm talking about one 359 00:31:31,940 --> 00:31:35,020 Now you broke it that's why we can't have nice things 360 00:31:36,740 --> 00:31:38,900 No, scratcher no fracture on the skull 361 00:31:40,620 --> 00:31:46,620 The whole purpose of this experiment is to figure out if it's worse to get a full bottle broken over your head or an empty 362 00:31:46,620 --> 00:31:49,180 Bottle broken over your head personally. I want neither 363 00:31:50,020 --> 00:31:56,700 But if I had to choose especially when it comes to skull fractures like this test here the full bottle deliberate more 364 00:31:56,940 --> 00:32:01,860 damaging skull fracturing force in the empty bottle, but we're not done for a punclose examination 365 00:32:02,260 --> 00:32:08,680 Jamie and I know many lacerations in the skull of this meat head and we wonder 366 00:32:09,420 --> 00:32:14,820 Perhaps in the area of lacerations an empty bottle might be worse than a full bottle 367 00:32:14,860 --> 00:32:20,900 We don't know so we're gonna stretch some skin over one of these heads and start hitting that with broken bottles. Yeah 368 00:32:23,820 --> 00:32:28,820 Three down at the bomb range the myth of the Irish all-leather cannon 369 00:32:29,340 --> 00:32:33,860 Took a hiding. I just can't call that lethal. No, I mean that's pathetic 370 00:32:35,060 --> 00:32:37,740 But our team of tanners aren't done yet 371 00:32:38,180 --> 00:32:45,140 They've set themselves the challenge of building an effective viable cannon from nothing but cowhide 372 00:32:45,140 --> 00:32:47,900 I have to massage the leather makes a better cannon 373 00:32:48,300 --> 00:32:55,900 Actually what makes a better leather cannon is a tension to detail and this time around the team is going all out to iron out 374 00:32:55,900 --> 00:32:58,460 The issues from its last outing. All right 375 00:32:58,460 --> 00:33:03,860 So one thing we figured out the other day when we fired off our pure leather cannon when the ball came out it actually 376 00:33:04,380 --> 00:33:10,480 Delaminated the inside of the cannon so what I'm doing right now is scraping up this leather enough so that the glue will 377 00:33:10,480 --> 00:33:14,080 Bite down on this leather and it'll stay together when we fire off the next cannon 378 00:33:14,500 --> 00:33:20,640 So just like everything else on this cannon. We're beefing it up so to speak this is our super breach plug 379 00:33:21,260 --> 00:33:25,540 Made out of 42 layers of leather. This is gonna get rolled into the cannon 380 00:33:25,860 --> 00:33:32,020 Charge goes here cannonball goes here when we set it off. Hopefully it goes like baboom and not like 381 00:33:34,860 --> 00:33:40,820 Now I'm working on the breach section what I've done is take the same cowhide cut it down to two inch wide strips 382 00:33:40,820 --> 00:33:47,620 I'm putting on the contact cement on both sides and then I'm laying those strips lengthwise around the back end of the cannon 383 00:33:47,620 --> 00:33:49,820 This is gonna strengthen up our breach area 384 00:33:49,820 --> 00:33:57,540 So that way it is strong enough to withstand the explosion of black powder in order to get our cannonball to launch with the back end 385 00:33:57,820 --> 00:33:59,820 sufficiently built up glued and 386 00:34:00,060 --> 00:34:04,460 Beaten into submission the team is optimistic about their chances of success 387 00:34:04,860 --> 00:34:08,660 This is the glass chamber. We're talking about a 12 inch diameter 388 00:34:08,660 --> 00:34:15,060 Not only that but the breach has been reinforced with so many straps that we have about that much holding up the back end 389 00:34:15,060 --> 00:34:20,620 I think there might be a possibility that we've made ourselves a working leather cannon 390 00:34:21,260 --> 00:34:23,720 Now I have a few finishing touches 391 00:34:24,260 --> 00:34:26,300 Just you know give it a little bit of beauty 392 00:34:26,900 --> 00:34:33,340 So under a veil of secrecy our material girl applies her fashionable finishing touches 393 00:34:34,780 --> 00:34:38,420 Then it's back down to the bomb range drum roll, please 394 00:34:40,140 --> 00:34:46,620 The big reveal I was getting bored with the plain old leather cannons since we did so many I thought why not 395 00:34:49,420 --> 00:34:51,420 It's a designer 396 00:34:51,580 --> 00:34:54,100 That's crazy that is funny 397 00:34:54,100 --> 00:35:01,500 You just pimp this cannon out it looks the business but can it pack the punch a six ounce black powder punch 398 00:35:01,500 --> 00:35:05,940 When we ignite this it's gonna expand to three 55 gallon drums of gas 399 00:35:06,180 --> 00:35:11,500 That is a lot of energy and that is what's gonna fire our ball out of our cannon or blow our cannon up 400 00:35:12,180 --> 00:35:13,780 Either way, it's gonna be cool 401 00:35:13,780 --> 00:35:19,660 Next violence of the hams may be over but Jamie puts the lotion on the skin 402 00:35:19,700 --> 00:35:26,740 And finally carries disguised our cannon as a purse will the luggage leather be lethal 403 00:35:32,020 --> 00:35:36,140 As far as having a bottle smashed over your head at this point we've looked at concussions 404 00:35:38,060 --> 00:35:44,280 So it is moving around but not near as much as it was with full bottle. Yeah, we've looked at skull fractures 405 00:35:44,640 --> 00:35:46,640 No 406 00:35:47,280 --> 00:35:51,960 Skull fracture no skull fracture, but check out how nasty the lacerations are 407 00:35:52,120 --> 00:35:57,360 But we also need to look at lacerations because after all it's broken glass skin 408 00:35:57,560 --> 00:36:03,600 We're gonna get cut if I'm gonna be testing what happens to someone's scalp when they're hit over the head with a bottle 409 00:36:03,600 --> 00:36:07,960 I need a suitable scalp analog and to find it. Dr. 410 00:36:08,000 --> 00:36:16,600 Frankenheim nummon figures out some scalp attributes he wants to emulate that's moving about the same as the skin over my skull 411 00:36:18,760 --> 00:36:21,480 Poke through it 2.43 pounds 412 00:36:21,880 --> 00:36:31,160 This is very sort of fibrous next he finds the artificial materials with those physical attributes a vinyl epidermis 413 00:36:31,560 --> 00:36:36,400 absorbent subcutaneous layer and of course blood lots of blood 414 00:36:36,760 --> 00:36:43,000 What everywhere it all comes together in a disturbingly accurate avalogue of human skin 415 00:36:43,000 --> 00:36:49,000 Yep, the dermis goes on it like so and when I cut it with any luck, it's gonna bleed 416 00:36:51,560 --> 00:36:58,600 And with that there you go our fake skinned meathead is ready to take one for the team 417 00:36:59,480 --> 00:37:04,980 Let the lacerations begin laceration test with a full beer bottle three two 418 00:37:06,400 --> 00:37:08,400 Oh 419 00:37:19,640 --> 00:37:25,560 There's definitely some cuts there. Yep. Oh, it bleeds nasty nasty 420 00:37:25,560 --> 00:37:32,880 And if it was needed a further graphic illustration of how dangerous it is to use a bottle as a weapon 421 00:37:32,880 --> 00:37:38,800 Put that there and we'll put the other one there and we know that that's our full bottle 422 00:37:39,440 --> 00:37:41,440 compare to the empty one, okay 423 00:37:45,080 --> 00:37:50,920 Okay, here we go laceration test empty beer bottle into our meat buster 424 00:37:52,640 --> 00:37:54,640 Three two one 425 00:37:54,800 --> 00:37:56,800 A 426 00:37:58,360 --> 00:38:05,680 Successful smash and as with the full bottle it's immediately obvious damage was done. I like my fake skin 427 00:38:05,680 --> 00:38:07,680 It's a nice fake skin 428 00:38:07,840 --> 00:38:14,640 And an up close comparison sees very little difference in the damage to that skin between the two tests 429 00:38:14,640 --> 00:38:17,720 I don't know about you, but I look at these and they look pretty much equivalent to me 430 00:38:17,720 --> 00:38:21,040 Yeah, give or take a nick or two. It's the same. Yeah 431 00:38:22,040 --> 00:38:27,900 The original myth is that having an empty bottle broken over your head is worse for you than having a full bottle broken over your head 432 00:38:28,160 --> 00:38:31,080 Well from our testing from the standpoint of your brains 433 00:38:31,080 --> 00:38:32,200 It's not true 434 00:38:32,200 --> 00:38:37,880 You'll get a much worse concussion from a full bottle than an empty one and also from our testing on bones 435 00:38:37,920 --> 00:38:44,960 The full bottle is also worse. It's much more likely to cause a skull fracture than an empty bottle now with the skin laceration test 436 00:38:45,360 --> 00:38:50,920 Actually for the first time they're about even but that still doesn't make the statement that the empty bottle is worse 437 00:38:51,440 --> 00:38:56,520 Supportable so it's still not looking very good. In fact, I don't most say it's busted 438 00:38:58,000 --> 00:39:01,560 Okay, the myth that it's worse to have an empty bottle broken over your head than a full bottle 439 00:39:01,560 --> 00:39:04,560 Let's recap where we stand from the standpoint of your brains 440 00:39:04,560 --> 00:39:10,040 It's busted from the standpoint of your skull bone also busted from the standpoint of your skin 441 00:39:10,280 --> 00:39:14,120 No difference. Well, you know where that leaves us myth busted totally busted 442 00:39:22,040 --> 00:39:24,040 You 443 00:39:28,280 --> 00:39:29,080 Carrie 444 00:39:29,080 --> 00:39:33,680 Grantentory are about to find out if leather can be a lethal cannon 445 00:39:34,160 --> 00:39:38,800 This is our target. We have a barrier of milk backed by a triangulation of three water barrels 446 00:39:39,080 --> 00:39:44,280 Why milk? Well because it's gonna look really cool on high speed when our cannonball crashes into it 447 00:39:44,280 --> 00:39:47,680 And speaking of high speed with the aid of the high speed and this scale here 448 00:39:47,680 --> 00:39:53,520 We're going to be able to catch the velocity of the ball and see if it matches our parrot gun and finally here 449 00:39:53,520 --> 00:39:59,800 We have our designer inspired ultimate completely reinforced 100% genuine leather cannon 450 00:40:00,040 --> 00:40:04,280 If only the Irish had something this stylish at the siege of Balli Nally Castle 451 00:40:04,640 --> 00:40:08,720 Well, who knows if the cannon would have exploded, but at least they'd be fighting in style 452 00:40:09,040 --> 00:40:14,000 However, it's not style but performance substance that ultimately matters 453 00:40:14,600 --> 00:40:19,120 Remember the benchmark we're using is the parrot rifles muzzle velocity of 454 00:40:20,040 --> 00:40:24,460 389 miles per hour plus it has to be capable of multiple 455 00:40:25,120 --> 00:40:27,120 successful fire 456 00:40:27,120 --> 00:40:29,400 Man, this is the prettiest can I ever seen 457 00:40:29,960 --> 00:40:32,280 Carrie's disguise your cannon is a purse 458 00:40:32,840 --> 00:40:40,520 All it needs now is Jamie's favorite slippery solution. I saw this on dirty jobs once really yeah, except for it was a cow 459 00:40:40,560 --> 00:40:43,080 Isn't it yeah, whatever don't worry Betsy 460 00:40:44,840 --> 00:40:51,520 So why are we lubing up the barrel? Well the last time we tried the Irish leather cannon built to historical specifications 461 00:40:51,520 --> 00:40:56,280 The cannonball had a difficult time getting out of the barrel and it delaminated the innermost layer 462 00:40:56,320 --> 00:41:02,280 You don't want that to happen this time. So we're adding lube and hopefully it'll go shooting right out the end 463 00:41:02,920 --> 00:41:04,920 Are you in? Yep 464 00:41:05,320 --> 00:41:07,720 That's it. Okay, let's do it. I 465 00:41:08,560 --> 00:41:10,560 Think we have a very good chance 466 00:41:11,160 --> 00:41:14,240 80% at least the other 20% is it explodes 467 00:41:15,000 --> 00:41:19,360 So it's time to find out if the bling leather cannon can 468 00:41:20,080 --> 00:41:22,080 Here we go 469 00:41:22,240 --> 00:41:26,640 Inspired cannon three two one 470 00:41:38,080 --> 00:41:40,080 Oh 471 00:41:45,520 --> 00:41:47,520 The reaction says it all 472 00:41:50,800 --> 00:41:54,440 From back behind the blast shields the test looks to be a success 473 00:41:54,520 --> 00:41:59,680 But up close the evidence begins to contradict their initial reaction 474 00:42:00,760 --> 00:42:02,760 Punch through the cart no problem 475 00:42:03,040 --> 00:42:05,040 Hey 476 00:42:05,320 --> 00:42:12,840 Unlike the parrot rifle which easily punched through two water barrels the leather cannon only just pierced the milk cart 477 00:42:14,000 --> 00:42:16,640 You're definitely gonna give somebody a bruise with that 478 00:42:18,280 --> 00:42:26,360 I'll leave Thaladee assessment that's backed up by the numbers from the high speed. So I've got 52 point five miles per hour 479 00:42:26,560 --> 00:42:31,560 Wow, you could drive faster than that cannonball came out of the cannon 480 00:42:31,560 --> 00:42:35,600 Yep, but look it's entirely made out of leather. He's right. That is awesome 481 00:42:35,600 --> 00:42:42,600 The less than lethal muzzle velocity was caused by what is the final nail in the leather cannon coffin the 482 00:42:43,160 --> 00:42:45,160 delamination of the barrel and 483 00:42:45,240 --> 00:42:50,040 Deformation of the combustion chamber and that can only mean one thing 484 00:42:50,400 --> 00:42:53,120 It looked like it was gonna be plausible for a second there 485 00:42:53,120 --> 00:42:58,520 But you can only get one shot out of it. I think this one's busted busted that man 486 00:42:58,880 --> 00:43:03,120 What a way to go out this looking cool. Yes, we got one good shot out of it 487 00:43:11,520 --> 00:43:15,400 Leather it's good for fashion not good for artillery
