0:00:10.600,0:00:14.256 -Well, there is a myth that says that[br]if you're on a ship when it's sinking, 0:00:14.281,0:00:16.081 it will suck you down with it 0:00:16.127,0:00:18.821 -You're telling me that this thing, [br]when it goes down, 0:00:18.835,0:00:21.812 I'm going to go down with it[br]because it's going to suck me down 0:00:21.881,0:00:22.638 -Yeah 0:00:22.638,0:00:26.011 -So, what are the prevealing theories[br]behind the boat sucking me down? 0:00:26.011,0:00:29.785 -Well, apparently there are three[br]and the first one is that air 0:00:29.795,0:00:33.213 that mixes in with the water as[br]it rushes up from the boat 0:00:33.527,0:00:36.621 makes the water less dense [br]so it's like you're going to fall 0:00:36.637,0:00:38.757 through the water quicker that way 0:00:38.907,0:00:43.921 Uh, the second theory is that the cavities[br]in the ship will create an area for 0:00:43.921,0:00:47.686 the water ​to rush in and that'll [br]pull you into the ship and then 0:00:47.686,0:00:52.053 the third one is that the ship moving[br]through the water rapidly towards 0:00:52.053,0:00:56.548 the bottom will create a vortex above it[br]kind of like drafting behind a truck when 0:00:56.548,0:00:58.248 it's on a highway 0:00:58.330,0:01:01.710 -You know, all these theories seem to me[br]simple enough to actually test 0:01:01.710,0:01:05.678 on the shop. I think I could build a small[br]water rig with a bubbler and some weights 0:01:05.678,0:01:10.048 some small boats and we could see all[br]three these theories right by the shop 0:01:10.545,0:01:14.207 -Yeah, but, you know, I still think that[br]we need a real boat. 0:01:14.207,0:01:17.087 People ain't going to get it[br]unless we do it with a real boat 0:01:17.087,0:01:18.217 (music) 0:01:18.402,0:01:23.312 -Until they find a suitable boat,[br]Adam sets out to test the vortex 0:01:23.312,0:01:26.483 and bubble density theories on[br]a small scale 0:01:26.483,0:01:30.263 -Well, what I made is a miniature bubbling[br]rig and we are trying to show whether 0:01:30.263,0:01:34.213 or not the ship produces a lot of bubbles[br]and the bubbles lower the density of water 0:01:34.213,0:01:38.642 people sink whereas normally they'd float[br]or whether it creates a vortex that 0:01:38.642,0:01:40.383 pulls things in after it. 0:01:40.426,0:01:44.856 This would be the Titanic, this is[br]a lead weight, it's pretty darn heavy 0:01:44.955,0:01:48.195 and let's say that is our person[br]right there 0:01:48.195,0:01:50.185 We are ready 0:01:55.275,0:01:57.693 Squat, nothing 0:01:57.825,0:02:04.135 -To make this work, Adam has to rethink[br]his ratios of weight, density and buoyancy 0:02:04.485,0:02:06.215 (music) 0:02:06.435,0:02:10.435 -Adam is building a rig four feet square[br]by ten feet high. 0:02:11.025,0:02:15.975 They'll then attach an electric winch and[br]guided wires to hold a special box 0:02:15.975,0:02:19.315 that will simulate the action of[br]a sinking boat 0:02:22.265,0:02:26.607 -So right now I'm actually just[br]finishing up the PVC matrix that will be 0:02:26.607,0:02:34.238 our bubbler and hopefully it'll provide us[br]with a really attractive stream of bubbles 0:02:34.861,0:02:39.241 Then I'm going to make a panel for the top[br]of this box which has a hole on it 0:02:39.241,0:02:42.912 so that not only can we test what happens[br]when you drop a weight in water but 0:02:42.912,0:02:46.602 when you drop a weight with an air gap[br]in it we can see what happens 0:02:46.641,0:02:49.340 We are going to fill this[br]with 25 pound barbell weights 0:02:49.340,0:02:55.288 -Encinal High School in Alameda agrees to[br]host a Mythbusters midsize experiment 0:02:56.290,0:03:01.223 The school's diving pool at 12 feet deep [br]is ideal for the new rig 0:03:01.223,0:03:03.009 -Oh, it's a beautiful story 0:03:03.009,0:03:08.093 -The plan is to see what specific forces[br]are in play when a ship sinks 0:03:09.613,0:03:12.714 -At this point I really don't know what [br]is gonna happen with this 0:03:12.714,0:03:18.557 You know, my impression is that if you're[br]floating above a boat as it's going down, 0:03:18.557,0:03:20.402 it's not really going to pull you down 0:03:20.402,0:03:24.972 -Jamie's pessimistic about the vortex[br]theory but he's open to the bubbles 0:03:24.972,0:03:28.472 creating lower density.[br]-I don't know if it's going to blow you up 0:03:28.472,0:03:32.472 because of all the bubbles going up or[br]whether the bubbles will make the water 0:03:32.472,0:03:37.362 in that area less dense will make you[br]go down. It'll be interesting to see 0:03:39.058,0:03:40.838 This is lead shot 0:03:40.838,0:03:45.498 -Water densitity is the key so[br]they've made a hydrometer, a simple 0:03:45.498,0:03:50.501 flotation device that measures the[br]specific gravity or density of a liquid 0:03:50.651,0:03:55.588 -We'll see how much the density of[br]the water changes by how far this goes up 0:03:55.588,0:04:00.158 and down when the water's aerated.[br]That's perfect 0:04:00.978,0:04:06.208 -Experiment one: the bubble test[br]-A compressor will supply air 0:04:06.208,0:04:10.788 to Adam's PVC bubble matrix.[br]- Okay, I'm going. 0:04:10.788,0:04:14.988 -Alright, I'm going to watch it[br]Oh, that looks cool from here 0:04:15.914,0:04:18.744 (laughter) 0:04:20.559,0:04:24.559 -It looks like it's going down, yes[br]-Oh, way down 0:04:24.923,0:04:30.443 -Okay, is out of the... looks like someone[br]is gonna have to get their swim trunks on 0:04:30.684,0:04:35.784 -And that's all the encouragement[br]Adam needed on a warm California day 0:04:35.784,0:04:37.980 -Can we blur out the love handles?[br]-No! 0:04:37.980,0:04:41.784 -Be nice to me alright[br]-Happy with the bubble effect, 0:04:41.784,0:04:46.510 their first weight test should determine[br]if volume makes it easier to be dragged 0:04:46.510,0:04:48.191 down 0:04:48.206,0:04:53.014 So to get a closer simulation of[br]a sinking boat the box is positioned on 0:04:53.014,0:04:58.324 the surface and loaded with 200 pounds.[br]They hope the inrush of water 0:04:58.324,0:05:02.044 to the empty box will drive[br]the vortex effect 0:05:04.164,0:05:06.584 -Good, go! 0:05:13.333,0:05:14.913 -Wow 0:05:14.913,0:05:17.894 -I pulled it down[br]-That was intense 0:05:18.223,0:05:21.575 I didn't realize the result[br]would be so marked 0:05:21.575,0:05:25.235 When I'm in the water as the weight[br]releases I can definitely feel it pushing 0:05:25.235,0:05:29.265 this cushion of water out around it as[br]it's plummeting and I'll tell you 0:05:29.265,0:05:32.845 straight up based in what I see here[br]you'll definitely get sucked down 0:05:32.845,0:05:37.105 and I think the bigger the object,[br]the bigger the suck 0:05:37.430,0:05:40.354 -They increased the box weight[br]to 300 pounds. 0:05:40.354,0:05:43.970 -Alright, hydrometer is ready[br]-Okay, going 0:05:43.970,0:05:44.870 -Go 0:05:51.461,0:05:54.301 -Nice sound[br]-Yeah! 0:05:54.910,0:05:57.350 -Where's the hydrometer?[br](laughter) 0:05:57.350,0:05:59.707 -There it is![br](laughter) 0:06:01.679,0:06:05.049 -That pretty much says it[br]-Wow!
