1 00:00:00,000 --> 00:00:02,000 I 2 00:00:30,000 --> 00:00:32,000 I 3 00:01:00,000 --> 00:01:07,400 What's everybody freaking out about that is some bad hat Jamie 4 00:01:30,160 --> 00:01:39,040 So Jamie 2015 marks the 40th anniversary of one of the all-time great horror movies, and it is of course 5 00:01:42,400 --> 00:01:47,960 Jaws and we are going to celebrate by jumping back into the water with an entire episode devoted to sharks 6 00:01:49,240 --> 00:01:50,840 Cool, what's on the docket? 7 00:01:50,840 --> 00:01:57,400 Well later we're gonna be testing not one but two shark repellent miss one involves the sound of orcas repelling sharks 8 00:02:00,880 --> 00:02:03,440 And the other involves the essence of 9 00:02:04,600 --> 00:02:06,860 Well dead shark weird 10 00:02:08,160 --> 00:02:13,880 But first we are going to be retesting a myth that fans say we got wrong ten years ago 11 00:02:13,960 --> 00:02:16,960 That would be scuba tank explosion. Yes, okay 12 00:02:16,960 --> 00:02:23,360 So to recap it's the end of the movie and for chief Brody. It is killer be killed the sharks is racing towards him to eat him 13 00:02:23,360 --> 00:02:29,440 He's got a scuba tank sticking out of the corner of his mouth Brody lifts his 30-odd sex takes his shot 14 00:02:30,400 --> 00:02:36,160 And kills the shark but for us didn't work. No, it didn't but fans say our methodology was flawed 15 00:02:36,160 --> 00:02:41,600 And I think we should retest it. So what are we gonna need a bigger boat? I think that's accurate 16 00:02:43,200 --> 00:02:46,640 When the mythbusters first took aim at the jaws finale 17 00:02:52,280 --> 00:02:58,200 Their conclusion was controversial the final sequence of jaws, I'm sorry to say is totally busted 18 00:02:59,160 --> 00:03:03,160 So now ten years down the line, it's time for a do-over 19 00:03:03,800 --> 00:03:08,480 So fans had three specific questions the first time we tackled this myth number one 20 00:03:08,480 --> 00:03:15,320 What if Brody didn't shoot the tank directly but grazed it with this bullet causing a weakness that ruptured making the tank explode 21 00:03:20,040 --> 00:03:27,280 To what if Brody had a different gun is there a caliber of bullet that could cause a scuba tank to explode and 22 00:03:27,400 --> 00:03:31,800 Three and this is where we're actually starting this story. What happened to the tank when we shot it? 23 00:03:35,080 --> 00:03:38,720 The tank did not actually split all the way open it didn't explode 24 00:03:40,800 --> 00:03:46,660 It rocketed away. Yes fans wanted to know if a rocketing tank could actually harm a shark 25 00:03:49,440 --> 00:03:54,360 And to find out if a rocketing tank could kill the guys must build a life-size 26 00:03:55,240 --> 00:04:01,000 Super realistic shark stand-in and Adam starting that by getting anatomical 27 00:04:01,600 --> 00:04:04,460 John can you give me a little bit of shark anatomy? 28 00:04:05,240 --> 00:04:11,080 101 here sure this is a salmon shark. It's very similar to a white shark in fact 29 00:04:11,080 --> 00:04:19,040 It's in the same family only they don't get us large, but the inside is functionally identical very much the same Adam needs hands-on 30 00:04:19,200 --> 00:04:21,200 Experience for two reasons 31 00:04:21,200 --> 00:04:24,940 What is that? What is this giant thing? That's the liver first 32 00:04:24,940 --> 00:04:29,720 He must figure out the journey that a rocketing tank would take food will enter the esophagus 33 00:04:30,080 --> 00:04:35,920 He moved into the stomach. That's the stomach right here that I'm touching which turns out to be simple 34 00:04:36,280 --> 00:04:39,280 The tank would first shoot through a muscular sphincter 35 00:04:39,760 --> 00:04:46,440 Before entering the esophagus which goes right past the heart before opening into a thick walled stomach 36 00:04:47,440 --> 00:04:48,640 reason to 37 00:04:48,640 --> 00:04:49,680 Wow 38 00:04:49,680 --> 00:04:55,700 Which requires a bigger shark is about material research skin is so rough 39 00:04:56,680 --> 00:05:02,180 Adam must feel the insides to work out what to build his realistic replica from 40 00:05:02,440 --> 00:05:06,300 Wow, there's nothing soft about this thing at all. It is like shoe leather 41 00:05:06,720 --> 00:05:12,160 John McCosker's lesson for me in shark anatomy and provided me the opportunity to stick my entire arm 42 00:05:12,640 --> 00:05:16,460 Down the gullet of a seven-foot lemon shark 43 00:05:16,940 --> 00:05:21,300 Texturally it's an amazing experience because what's surrounding it is so 44 00:05:21,740 --> 00:05:28,620 Needy and tough and if we're going to anatomically match that we're going to need to add something that really comes akin to 45 00:05:29,900 --> 00:05:35,740 Significant musculature that surrounds that in a shark with the research phase now complete. Thank you, sir 46 00:05:35,860 --> 00:05:37,860 My pleasure 47 00:05:41,900 --> 00:05:46,080 The build can begin where Jamie's starting with a skeleton 48 00:05:47,460 --> 00:05:54,300 This stuff right here, which is expanded polypropylene and it's basically the same plastic that's in a portable gas can 49 00:05:54,300 --> 00:05:59,140 Is what we're going to be making our framework and our jaws out of because it's flexible 50 00:05:59,780 --> 00:06:05,260 Kind of like stiff cartilage. It's perfect and we can screw right through it. It's easily cut and drilled 51 00:06:05,940 --> 00:06:13,020 Having similar specs to a shark's cartilage and a skeleton is crucial for realistic structural integrity 52 00:06:13,620 --> 00:06:17,380 That actually doesn't look half bad, but for the rocketing tank test 53 00:06:17,940 --> 00:06:19,940 It's the gullet that's key 54 00:06:21,180 --> 00:06:26,820 And to replicate that we've decided to use cow hide this leather here because it's 55 00:06:26,980 --> 00:06:34,740 Tough like the inside of a shark based on what Adam saw with Dr. McCosker stitched together. It should be just what the doctor ordered 56 00:06:36,700 --> 00:06:39,100 The leather's tough texture is perfect 57 00:06:39,460 --> 00:06:42,820 But finding the right tool to tailor it 58 00:06:44,740 --> 00:06:46,740 Is a much tougher task 59 00:06:49,260 --> 00:06:52,460 Maybe not but once Jamie goes old-school 60 00:06:54,540 --> 00:06:59,260 Sometimes simpler is better. He's able to go hell for leather on both the esophagus 61 00:07:00,500 --> 00:07:02,980 There's my gullet and the stomach 62 00:07:03,540 --> 00:07:08,700 Both of which are not only to scale for a jaw-sized great white. Well, there we go 63 00:07:09,380 --> 00:07:10,420 gullet 64 00:07:10,420 --> 00:07:11,380 stomach 65 00:07:11,380 --> 00:07:13,780 But also have just the right feel 66 00:07:14,540 --> 00:07:19,580 This feels very similar to what it felt like sticking my hand in that shark's mouth at the Academy 67 00:07:20,820 --> 00:07:22,820 It's coming together 68 00:07:24,860 --> 00:07:31,180 Next Jamie moves on to muscle mass not how to do it to again give the shark that authentic anatomy 69 00:07:31,820 --> 00:07:35,300 These bits right here are going to be my shark muscle 70 00:07:35,500 --> 00:07:38,980 So I'm going to saturate them with a urethane rubber 71 00:07:39,220 --> 00:07:43,260 So the thing here is to get this carpet to soak up this resin 72 00:07:43,900 --> 00:07:52,340 We'll kind of apply them like bandages and create bands of muscles that'll be nice and meaty looking and also provide 73 00:07:52,460 --> 00:07:56,820 The kind of fibrous tensile support that holds everything together 74 00:07:58,980 --> 00:08:01,180 That was the last screw it's all yours 75 00:08:01,940 --> 00:08:07,020 With the internal structure now locked and loaded it's time to slip the shark some skin a 76 00:08:08,060 --> 00:08:11,020 Layer of two inch thick upholstery foam. Oh 77 00:08:13,500 --> 00:08:21,900 He looks right in proper which once treated with a neoprene primer and paint will have a somewhat similar strength to real shark skin 78 00:08:23,100 --> 00:08:25,700 Like black eyes like a doll's eyes 79 00:08:26,660 --> 00:08:28,660 I 80 00:08:30,620 --> 00:08:36,660 Kind of want to name him right now. There's Bruce and then there's Buster. I dub him 81 00:08:37,500 --> 00:08:39,500 Brewster 82 00:08:39,540 --> 00:08:41,540 Time to smile for the camera Brewster 83 00:08:46,540 --> 00:08:48,540 Suddenly I don't want to go swimming 84 00:08:48,700 --> 00:08:54,020 In terms of anatomical accuracy their shark is second to none. Let's get shooting 85 00:08:54,140 --> 00:08:56,740 But before turning a tank torpedo 86 00:08:57,740 --> 00:08:59,740 There's a second story to start 87 00:09:03,180 --> 00:09:08,140 Pop quiz what is the name of quince boat in jaws? No idea 88 00:09:08,820 --> 00:09:15,580 Okay, hey, so what was called the orca which is good because our next myth involves orcas or killer whales go on 89 00:09:15,580 --> 00:09:21,140 Well, as you know orcas are natural predators of sharks even the big ones like great whites or tiger sharks 90 00:09:21,140 --> 00:09:25,660 So it stands to reason that sharks might be afraid of orcas, right? Right? 91 00:09:25,660 --> 00:09:33,140 So it also stands to reason that some people say you can effectively get sharks to leave an area by playing the sounds of orcas under water 92 00:09:33,140 --> 00:09:35,820 And the sharks will head for the hills apparently 93 00:09:36,420 --> 00:09:40,460 How to separate sharks and swimmers has been a dilemma for decades 94 00:09:40,940 --> 00:09:46,340 But can playing orca noises in shark infested waters really be the solution 95 00:09:47,340 --> 00:09:53,220 To find out Adam and Jamie have hit the deep blue sea 96 00:09:56,780 --> 00:09:58,780 They're coming up on the boat 97 00:10:00,500 --> 00:10:05,140 Maybe stating the obvious bit. I think we've come to the right place 98 00:10:05,540 --> 00:10:09,060 They've come to the right place in more ways than one 99 00:10:09,260 --> 00:10:12,740 There's another reason this location is perfect for our test today 100 00:10:12,740 --> 00:10:19,060 And that is because orcas are not unknown to these waters. It's not incredibly frequent, but it's not infrequent either 101 00:10:19,300 --> 00:10:27,300 So it's pretty likely that the sharks we're dealing with would have heard at some point the sound of orcas swimming orcas on the hunt 102 00:10:27,300 --> 00:10:29,380 All the sounds we're going to be playing for them 103 00:10:30,460 --> 00:10:38,900 Having experience with killer whales is not essential because the myth is supposedly an instinctive behavior shown by all sharks 104 00:10:39,140 --> 00:10:41,140 So what's the plan? 105 00:10:42,140 --> 00:10:44,780 So down below there's an old shipwreck pretty soon 106 00:10:44,780 --> 00:10:51,860 There's going to be this bait box full of fish bits this omnidirectional speaker and by the way lots of sharks 107 00:10:52,660 --> 00:10:53,540 Up here 108 00:10:53,540 --> 00:10:56,500 I'll be meaning a comm system that I can use to both talk to Jamie and 109 00:10:56,700 --> 00:11:01,580 Play sounds through that omnidirectional speaker sounds of our control and sounds of killer whales 110 00:11:01,580 --> 00:11:03,980 Oh, by the way monitoring all this from underwater 111 00:11:04,380 --> 00:11:11,820 None other than James Franklin D. Heinemann the D stands for danger. He's right. The D does stand for danger 112 00:11:12,900 --> 00:11:17,500 Once the danger man is suited and booted it's go time 113 00:11:28,300 --> 00:11:33,780 From the moment he hits the water Jamie's surrounded by sharks, you know what they say 114 00:11:33,980 --> 00:11:36,780 You're gonna swim in sharks. You're gonna get fit 115 00:11:38,580 --> 00:11:45,180 Hopefully not today and by the time he reaches the wreck where visibility is eerily limited 116 00:11:47,300 --> 00:11:49,900 The sharks aggression appears to increase 117 00:11:50,900 --> 00:11:52,900 They're coming in fairly close 118 00:11:53,660 --> 00:11:57,780 So much so that even the danger man is beginning to freak out 119 00:11:58,660 --> 00:12:03,140 Okay, we're seeing a lot of activity in tight close right now 120 00:12:04,980 --> 00:12:09,460 I must say the sharks behavior are being really aggressive 121 00:12:20,300 --> 00:12:26,020 It's shark week I love saying that we are in the Bahamas the waters full of sharks and a Heinemann 122 00:12:26,620 --> 00:12:31,580 And we're trying to determine if the sound an orca makes underwater is a reasonable shark repellent 123 00:12:32,540 --> 00:12:38,860 As this incredible footage shows even large tiger sharks are no match for killer whales 124 00:12:39,180 --> 00:12:45,780 But does that mean that on hearing their calls sharks will instinctively high tail it out of there terrified? 125 00:12:46,460 --> 00:12:50,420 Well having realized that the sharks aren't hungering for a Heinemann 126 00:12:52,420 --> 00:13:00,540 A more relaxed Jamie positions the underwater speaker. Hello guy, which will first play not orca sounds but a control 127 00:13:00,660 --> 00:13:06,260 What is our control noise? It is specifically recordings of the sounds that humpback whales make underwater 128 00:13:11,100 --> 00:13:17,300 This is an ideal control a number one they make very loud sounds that can be heard for many miles underwater to their 129 00:13:17,500 --> 00:13:20,460 Ubiquitous to all the oceans of the world three 130 00:13:20,460 --> 00:13:22,260 They are not predators of sharks 131 00:13:22,260 --> 00:13:28,980 So there's no reason the shark would look for any danger from the whale sound it makes an ideal control to the orcas sound 132 00:13:30,660 --> 00:13:32,660 It 133 00:13:33,300 --> 00:13:35,300 Looks like we've got around 134 00:13:35,300 --> 00:13:42,100 16 sharks very interested in what we're doing here on this wreck. I think we're good to go 135 00:13:42,660 --> 00:13:48,740 Copy that sir. I am about to press play on our control sound the humpback whale in three two 136 00:13:49,740 --> 00:14:03,460 That's definitely calling the home planet and again just for clarity 137 00:14:05,100 --> 00:14:07,780 At this point you might be wondering to yourself self 138 00:14:07,940 --> 00:14:14,920 How do sharks actually hear it's a good question and the answer is cool because they have two distinct organs for detecting sound 139 00:14:15,360 --> 00:14:18,000 First is their ears on each side of their head 140 00:14:18,000 --> 00:14:23,400 They have a hole that leads to an ear canal and inside of that are sensory macula which detect sound 141 00:14:23,720 --> 00:14:28,920 But in addition running down the length of their entire bodies is an organ called the lateral line 142 00:14:28,920 --> 00:14:34,800 Which can detect vibration and what can cause vibration underwater? Yes sound waves 143 00:14:37,120 --> 00:14:41,360 What that means is that the sharks are definitely hearing the whale song 144 00:14:42,040 --> 00:14:45,300 But reacting to it they ain't 145 00:14:55,600 --> 00:15:01,600 So will the sharks behavior change when they're hearing not whales, but their killer cousins 146 00:15:02,160 --> 00:15:07,760 Jamie we are commencing to play the orcas sounds in three two one and go 147 00:15:11,360 --> 00:15:13,360 You 148 00:15:20,120 --> 00:15:25,760 Can run but you cannot hide that's what they're saying first impressions are not good as the sharks neither run 149 00:15:33,480 --> 00:15:35,480 But all is not 150 00:15:35,760 --> 00:15:41,080 Just to be clear orcas apparently have a very sophisticated language lots of different sounds that they make 151 00:15:41,360 --> 00:15:43,560 Some are communicating with each other others are hunting 152 00:15:43,560 --> 00:15:49,960 We are playing a greatest hits medley of orcas sounds in case one of them trips up or triggers the sharks 153 00:15:49,960 --> 00:15:56,800 That's what we're looking for by playing a mix of sounds including what scientists think are hunting noises 154 00:15:57,480 --> 00:16:01,080 The guys are increasing the chances of the sharks getting spooked 155 00:16:05,680 --> 00:16:08,400 But after ten minutes of manic medley 156 00:16:09,120 --> 00:16:12,480 This so sounds like a later miles Davis album 157 00:16:14,120 --> 00:16:16,120 There's no change at all 158 00:16:27,120 --> 00:16:31,760 Copy that that's pretty definitive you want to come to the surface okay? I'm coming up 159 00:16:31,960 --> 00:16:36,360 Nice quick change I was chilly 160 00:16:36,920 --> 00:16:40,160 Okay, look I like the theory that this story 161 00:16:40,560 --> 00:16:47,480 Proposes that killer whales are a natural predator for sharks air go the sounds that killer whales make might make sharks 162 00:16:47,480 --> 00:16:50,920 I tell you that of the area that makes sense to me well 163 00:16:51,000 --> 00:16:56,760 It may make sense, but I didn't see any evidence of that at all those sharks didn't care what sounds we were playing 164 00:16:56,760 --> 00:17:01,460 So this one's busted. It's got to be all right. Let's go get some fish and chips sounds good 165 00:17:02,540 --> 00:17:04,540 I 166 00:17:09,280 --> 00:17:15,120 Max of jaws is one of the most famous finales in film history 167 00:17:21,680 --> 00:17:23,960 But when the myth busters put it to the test 168 00:17:24,480 --> 00:17:26,480 Three two 169 00:17:29,360 --> 00:17:32,900 They got not a bomb but a rocket hey 170 00:17:37,400 --> 00:17:39,400 Now ten years later 171 00:17:40,200 --> 00:17:43,560 The myth busters are re-tackling this fan favorite 172 00:17:43,840 --> 00:17:51,040 To find out once and for all if a rocketing air tank could have killed jaws our shark is of course done 173 00:17:51,040 --> 00:17:56,240 But that is only half of his raison death well it's time for you to go for a swim low buddy 174 00:17:56,360 --> 00:18:01,720 No in order to fulfill his given purpose. He needs to be shot at nice 175 00:18:02,880 --> 00:18:04,880 He's flying 176 00:18:04,960 --> 00:18:10,120 Specifically for the right ambience. He needs to be shot at in water. Oh, he looks so good 177 00:18:10,120 --> 00:18:15,800 And that is of course what's behind me pit 232 in lovely, I own California soon 178 00:18:15,800 --> 00:18:20,160 We will lower our shark into this water and we're gonna be shooting out on the movie 179 00:18:20,200 --> 00:18:22,720 Jaws has a scuba tank with its end right about here 180 00:18:23,400 --> 00:18:29,640 In our earlier tests we found that if we shoot a tank like that the air coming out of that makes the tank 181 00:18:29,880 --> 00:18:36,640 Effectively a rocket so for our first test we want to find out what happens to that rocket. Does it go through the esophagus? 182 00:18:37,320 --> 00:18:43,040 Because if it does and it makes it through the gullet and into the stomach our expert at Academy of Science 183 00:18:43,240 --> 00:18:49,440 Indicates that that's gonna mean that it's ruptured a bunch of sensitive organs along the way and that means a dead shark 184 00:18:50,600 --> 00:18:56,480 That's the theory and to put it to the test Brewster is carefully driven into the drink 185 00:19:04,160 --> 00:19:07,320 That right there my friends is a perfect freaking shark 186 00:19:09,040 --> 00:19:14,400 Adams right Brewster is the most anatomically accurate shark analog they've ever built 187 00:19:14,680 --> 00:19:19,940 But he's only complete with a standard scuba tank that's storing some serious energy 188 00:19:21,160 --> 00:19:23,760 That looks perfect Jamie excellent 189 00:19:24,800 --> 00:19:30,960 With nearly everything matching the clip including the gun and the distance to the target 190 00:19:31,200 --> 00:19:35,120 So how are you feeling? I'm feeling good. We're sighted in ready to shoot. All right 191 00:19:36,720 --> 00:19:42,240 Will they turn the tank into a shark killing torpedo the gun is hot 192 00:19:51,040 --> 00:19:53,040 I 193 00:19:53,040 --> 00:19:56,800 Can still see the tank, but it didn't make it past the gullet 194 00:19:58,120 --> 00:20:02,840 Well, we just put the tank in our shark's mouth. We fired at its bottom a perfect hit 195 00:20:03,760 --> 00:20:06,160 It behaved exactly as we expected 196 00:20:06,760 --> 00:20:12,020 The tank started releasing its pressure through the bullet hole which drove the tank into 197 00:20:12,480 --> 00:20:16,600 Brewster's gullet, but not past as esophagus at this point 198 00:20:16,600 --> 00:20:24,080 It looks like it might be survivable for our shark that the tank just got wedged in his throat and he could potentially 199 00:20:25,000 --> 00:20:30,360 Parastaltically cough it back up like 2005. They got a rocket and not a bomb 200 00:20:30,760 --> 00:20:38,560 Dude, it's not very toughly wedged in there and at a closer inspection shows that the rocket didn't have the power to sink their shark 201 00:20:38,960 --> 00:20:42,680 There's your problem. It's pretty good deal. You call the shark doctor 202 00:20:42,680 --> 00:20:48,560 So the bullet hole did in fact turn this tank into a bit of a rocket 203 00:20:49,480 --> 00:20:54,040 But it wasn't aggressive enough to actually do any damage to Brewster 204 00:20:54,040 --> 00:21:00,440 We didn't see any indication of ripping or tearing in the mouth or the esophagus and the tank went into the shark 205 00:21:00,440 --> 00:21:06,440 But it didn't go past the gullet. So as far as we can tell it's Brewster one Brody Nell 206 00:21:07,280 --> 00:21:12,120 Still to come Brody does get his fire in the hole three two 207 00:21:12,800 --> 00:21:13,800 one 208 00:21:16,800 --> 00:21:20,200 But next it's Adam's turn to put his life on the line 209 00:21:26,280 --> 00:21:32,120 The mythbusters have just confirmed that a tank that becomes a rocket courtesy of a bullet from Brody 210 00:21:35,520 --> 00:21:37,520 It's a fire-breathing dragon of a shark 211 00:21:38,120 --> 00:21:43,040 Would not have killed Jaws so it's time to go for a broke on the boom 212 00:21:44,960 --> 00:21:51,120 Now with the second test we are now going to try and implement the fan suggestion of not just shooting the tank with a bullet 213 00:21:51,120 --> 00:21:57,480 But shooting it on the angle creating potentially a wider bullet hole and a fatal breach that could potentially 214 00:21:58,000 --> 00:22:00,000 Cause the tank to explode. Let me explain 215 00:22:01,280 --> 00:22:04,360 Now in the previous test I shot the tank here now 216 00:22:04,360 --> 00:22:08,400 I'm going to be attempting to shoot about here that is on a much more 217 00:22:08,600 --> 00:22:14,280 Glancing angle to the surface of that tank and it could potentially cause either a wider bullet hole or 218 00:22:14,640 --> 00:22:21,160 The bullet could dig in and climb back out creating a breach that causes the tank to blow up completely 219 00:22:22,280 --> 00:22:29,400 That's the fan theory, but with a new tank for Adam to take down will they get the explosion this myth needs? 220 00:22:35,320 --> 00:22:41,880 I heard it go tank. I see a ricochet point dead center for the tank 221 00:22:44,840 --> 00:22:47,400 With no boom the guys go again 222 00:22:50,680 --> 00:22:55,560 I feel like I moved the tank and again how much abuse can this tank take 223 00:22:57,960 --> 00:23:03,000 It's just glancing off the side of that tank and a couple more times for good measure 224 00:23:03,800 --> 00:23:08,040 Now we fired six glancing shots to the side of the tank to get it to split open 225 00:23:08,680 --> 00:23:14,680 But they're all just a ricocheting off. So instead of these standard 30 odd six rounds 226 00:23:15,440 --> 00:23:20,400 We're going to use these which are 30 odd six armor piercing rounds 227 00:23:20,400 --> 00:23:25,400 If these can't cause a fatal breach while hitting the side of the tank well, then nothing will 228 00:23:26,360 --> 00:23:33,640 Fire from the same gun as the film will this armor piercing projectile finally deliver a detonation 229 00:23:44,760 --> 00:23:48,200 Now we had feedback or criticism rather from viewers that 230 00:23:48,520 --> 00:23:53,400 Said that Brody could have possibly hit a glancing blow along the side of the tank 231 00:23:53,400 --> 00:23:56,760 Which would open it up like a zipper and cause an explosion 232 00:23:57,320 --> 00:24:01,320 At this point we fired six bullets in that orientation of the tank 233 00:24:01,720 --> 00:24:07,080 And then a seventh one which was armor piercing and not one of them actually did that so at this point 234 00:24:07,240 --> 00:24:09,720 It's brooster two brody nil 235 00:24:10,600 --> 00:24:12,600 While brody works on a plan c 236 00:24:14,360 --> 00:24:16,360 What else is on the dark? 237 00:24:17,240 --> 00:24:21,640 Next up dead shark repellent. Why would you want to repel a dead shark? 238 00:24:22,200 --> 00:24:26,360 No, no the use of a dead shark as a repellent that supposedly 239 00:24:26,440 --> 00:24:29,160 The myth is sharks don't like the smell of other dead sharks 240 00:24:29,320 --> 00:24:33,400 Thus if you have the essence of dead shark on you, you will be protected from sharks 241 00:24:33,720 --> 00:24:38,680 Well, there's a certain morbid logic to that. I totally agree and I think we should test it 242 00:24:40,680 --> 00:24:42,440 Had to do just that 243 00:24:42,440 --> 00:24:47,080 It's back to the bahamas. What is the origin of this story? Well, it comes from fishermen 244 00:24:47,080 --> 00:24:52,280 They learned that if they dragged the dead shark behind their boat it kept sharks from eating their catch 245 00:24:52,840 --> 00:24:55,640 We are not going to test this by strapping a dead shark to jayme 246 00:24:55,880 --> 00:24:59,400 I'm getting in the water with those guys to be a little more scientific 247 00:24:59,400 --> 00:25:03,960 We're going to use this this little bottle is full of distilled essence of dead sharks 248 00:25:08,120 --> 00:25:11,480 That's bad to me, but apparently it's kryptonite to a shark 249 00:25:11,960 --> 00:25:14,280 Although it started as a fisherman's fable 250 00:25:14,920 --> 00:25:16,920 There is science to this story 251 00:25:18,200 --> 00:25:22,040 So i've done some research into this stench of death thing and it's pretty interesting 252 00:25:22,680 --> 00:25:27,080 It was first observed by the ecologist eo wilson and social ants 253 00:25:27,560 --> 00:25:32,920 He noticed that when an ant died its buddies picked it up and carried it off to some sort of ant cemetery 254 00:25:33,400 --> 00:25:37,800 And so he found that what was happening was that the ant was releasing something called 255 00:25:38,360 --> 00:25:43,080 Oleic acid when it died and the other ants were picking up on it and that's why they did that 256 00:25:43,480 --> 00:25:49,480 Since then other scientists have noticed the same phenomenon and things like cockroaches and wood lice 257 00:25:49,720 --> 00:25:53,640 And it kind of makes sense if you think about it. I mean if something killed your buddy 258 00:25:54,360 --> 00:25:56,360 It might want to kill you too 259 00:25:56,600 --> 00:26:03,880 That's the theory for insects, but sharks will supposedly head for the hills when they encounter the stench of death 260 00:26:04,760 --> 00:26:06,760 Time to put that to the test 261 00:26:06,760 --> 00:26:12,280 Here's our plan first up, of course, we need sharks to that end 262 00:26:12,360 --> 00:26:16,200 We buried a bait box full of fish guts in a fake rock down at the bottom 263 00:26:16,360 --> 00:26:21,000 And it is slowly doing our work for us of gathering together a large swarm of sharks 264 00:26:21,560 --> 00:26:25,800 When the swarm's big enough i'm gonna go down there and release essence of dead shark 265 00:26:26,440 --> 00:26:28,440 Right into the middle of it 266 00:26:28,680 --> 00:26:31,160 I will also be underwater, but a few dozen feet away 267 00:26:31,240 --> 00:26:37,400 So I can watch carefully for any behavioral difference in the sharks once jayme releases the essence 268 00:26:37,560 --> 00:26:41,080 Whether they get skittish whether they flee or whether they don't seem to notice at all 269 00:26:44,280 --> 00:26:48,440 For jayme the preparation's easy for adam not so much 270 00:26:48,840 --> 00:26:55,000 I got this thing with my ears there. It's a long story, but they're broken effectively and so I need to go down in a special helmet 271 00:26:55,400 --> 00:26:58,440 It'll give me full calm. I'll be able to talk to jayme best of all 272 00:26:58,840 --> 00:27:02,120 I'll be able to wear my glasses underwater. That's never happened before 273 00:27:03,160 --> 00:27:05,160 Slowly but surely 274 00:27:08,280 --> 00:27:15,080 Adam sinks to the seabed before he then takes up his position and starts crunching the numbers 275 00:27:16,760 --> 00:27:20,760 All right, I counted least uh one two three four five six seven 276 00:27:21,880 --> 00:27:25,000 At least a dozen sharks if not maybe close to 20 277 00:27:25,320 --> 00:27:31,800 That's jayme's cue to get in and swim to their bait filled fake rock 278 00:27:33,880 --> 00:27:35,880 How you doing over there adam?
