WEBVTT 00:00:00.000 --> 00:00:06.439 All right, welcome to Channel Super Fun, where today we're going to be making a wicked vacuum cannon. 00:00:09.519 --> 00:00:14.080 So, we originally 3D printed these special ends for this PVC pipe that 00:00:13.040 --> 00:00:18.320 we're going to be shooting the stuff out of. 00:00:16.160 --> 00:00:24.480 Dennis, we need things to shoot and we also need things to shoot at. We have 00:00:20.480 --> 00:00:25.680 wood. What's ud? Piece of wood. Okay. 00:00:24.480 --> 00:00:30.800 What a joke. You're a joke. All right. Well, the way that this thing 00:00:28.640 --> 00:00:35.360 works here, for those of you that don't know, is there's a tube here, right? So, 00:00:34.000 --> 00:00:39.760 what we want to do is shoot something out of this tube. But how are we going to do it? Well, we're going to tape off 00:00:38.480 --> 00:00:43.840 both ends. We're going to put something in beforehand. Then, we're going to suck 00:00:42.160 --> 00:00:48.160 all the air out of this darn thing through this tube and this vacuum pump 00:00:45.760 --> 00:00:51.760 through this hole right here. It's going to have a lot of negative pressure in 00:00:49.920 --> 00:00:56.719 there. And then when we pop the end with the tape on the other side, it's going 00:00:53.760 --> 00:01:01.199 to let all that atmospheric asm atmospheric pressure run into this and 00:00:59.600 --> 00:01:04.879 shoot that thing out the other side real fast. Supersonic speed. That's what I 00:01:03.039 --> 00:01:08.000 mean. So, we're going to first try and shoot something at that styrofoam. See 00:01:06.880 --> 00:01:12.240 if we can mess it up. Dude, this thing looks pretty good. This is just like paper tape or 00:01:11.040 --> 00:01:19.469 whatever. I'm just going to put it on here so the edges are smoother so this thing rips through there harder. 00:01:20.960 --> 00:01:26.159 Why is there an egg frying on your hand? I'm on fire. 00:01:24.640 --> 00:01:29.759 This is the best tape to use cuz it's pretty strong. So, you just put it on 00:01:27.920 --> 00:01:34.640 there. You make sure it's got a nice seal. Not like the Singer seal. Not like 00:01:32.479 --> 00:01:38.880 the animal seal, but just like a nice It's touching all the edges. And then 00:01:36.560 --> 00:01:44.240 you want to come over here and do the same thing to this one. Woo. Looks like 00:01:42.400 --> 00:01:47.119 it's lined up pretty good. So, we're going to use that as our thing to pop 00:01:45.680 --> 00:01:51.040 the other side. Okay. Okay. So, this part is kind of dangerous. So, make sure 00:01:49.520 --> 00:01:55.920 nobody's standing in the trajectory zone. Don't stand in front of there. 00:01:52.720 --> 00:01:58.799 Stand to the side. Keep it alive. Ride 00:01:55.920 --> 00:02:01.280 or die. Dennis, do you want to do the honors? 00:02:00.320 --> 00:02:04.719 What are you going to do? Pop it. Yeah. How are you going to do it? Are you going to hit it hard and up the 00:02:04.159 --> 00:02:09.759 whole thing? I I know. I don't believe you, dude. Trust me, Dennis, I give you the honors 00:02:08.000 --> 00:02:15.560 of turning the pump on. How about that? Where's this week? Let's do it. So, we got the pump 00:02:12.560 --> 00:02:15.560 tension. 00:02:17.520 --> 00:02:23.200 What else should we shoot? We should shoot something else. Dennis, I'd like you to stand in the front there. 00:02:21.760 --> 00:02:29.720 Lower your face. No, it's just for testing. It's just for testing. Do you need anger management, Dennis? 00:02:26.720 --> 00:02:29.720 Go. 00:02:30.000 --> 00:02:37.120 Wa. Okay, turn off. You need to go through here. We need a ping pong ball. 00:02:34.800 --> 00:02:40.800 What is it? A metal slug. 00:02:38.800 --> 00:02:44.480 Maybe. Let's try it. Wa. 00:02:43.519 --> 00:02:47.360 You shoot it. It It skipped it. It did a high jump over 00:02:46.879 --> 00:02:53.120 it. Dennis, what can we shoot out of it? Dennis, I need your help for once in my 00:02:51.280 --> 00:02:56.519 life. You need to help me look for things like this. 00:02:58.959 --> 00:03:03.120 Wo, that's really dirty. I've never hit anyone with this. 00:03:02.560 --> 00:03:08.000 Answer it. Just showering. You know what hurts? Ow. 00:03:06.480 --> 00:03:12.319 That's That hurt. Yeah, it's metal. 00:03:10.000 --> 00:03:14.800 You can't whip me with some metal. Okay, Dennis, can you collect a lot of little 00:03:13.920 --> 00:03:20.560 rocks? I hate nature. So much dust and leaf 00:03:18.000 --> 00:03:26.000 dros. Are this good? Not enough. We need more. 00:03:23.680 --> 00:03:31.200 Collect more. There's a hole. 00:03:28.080 --> 00:03:33.200 You can't see neighbor. 00:03:31.200 --> 00:03:37.440 You can kind of just check them out. Why are you checking out your neighbors? 00:03:35.040 --> 00:03:42.799 Okay, we need to break something. Wa! We can't get anything to really 00:03:40.000 --> 00:03:46.480 work. That one was heavy, but it still just bounced off there. I think what I'm 00:03:44.640 --> 00:03:51.440 going to do is put I'm going to try and shoot this now. 00:03:48.560 --> 00:03:55.640 This will be our shotgun casing. These will be our little fragments. 00:03:56.959 --> 00:04:03.040 Except we don't have Dennis anymore. Dennis had to be uh deported. Sorry 00:04:00.720 --> 00:04:06.400 guys. The government came today, picked him up, scooped him away, and said, 00:04:04.400 --> 00:04:09.120 "You're never coming back here." So, we said, "Can we at least keep his car and 00:04:08.080 --> 00:04:13.760 all that sort of thing?" And they said, "Yes, you can." And uh so that was that. 00:04:11.599 --> 00:04:18.239 That was the end of Dennis. So RIP Dennis. He's going back to Mongolia. And 00:04:16.400 --> 00:04:22.220 uh we'll see him in another life. So I hope you guys don't miss him cuz we 00:04:20.720 --> 00:04:23.919 certainly don't. 00:04:23.919 --> 00:04:29.280 Oh no. It sucks. Didn't even break the 00:04:27.040 --> 00:04:33.440 pop can. How did it come out so much harder last time? 00:04:31.680 --> 00:04:38.520 Okay, so I think I'm going to try and screw this in. So now this is going to 00:04:35.199 --> 00:04:38.520 be our bullet. 00:04:39.199 --> 00:04:46.720 I think it was too big and heavy. This might work better. It's just a piece of 00:04:43.280 --> 00:04:48.400 tube with some metal at the back. 00:04:46.720 --> 00:04:51.360 We're doomed. It's never going to work. I actually don't know what to do 00:04:49.759 --> 00:04:57.440 anymore. We need a ping pong ball. That's the only thing that I think will work. Okay, so we can't get anything to 00:04:55.360 --> 00:05:02.960 fire out of the vacuum cannon properly. It hardly even shoots anything. So, 00:04:59.840 --> 00:05:05.680 let's go find some more to shoot. Okay, 00:05:02.960 --> 00:05:10.240 so we got these like Easter I don't know what the hell these are, 00:05:07.520 --> 00:05:15.520 but they like just fit in here. Oh, would you look who back? 00:05:13.120 --> 00:05:18.880 The Eastern Devil. Stand in there. I'm going to shoot you with an egg. It's 00:05:16.800 --> 00:05:25.280 very soft. Don't worry. Seriously, this is what most people have to do for 00:05:21.840 --> 00:05:26.240 their citizenship. I'm not joking. 00:05:25.280 --> 00:05:31.680 Read the handbook. Yeah. Oh, 00:05:30.320 --> 00:05:37.160 okay. Hey, I'm actually glad that you're back, Dennis, cuz I didn't have a little 00:05:33.440 --> 00:05:37.160 to help me for a while. 00:05:40.400 --> 00:05:48.720 Okay, let's see how far this thing can go. Fire. 00:05:45.360 --> 00:05:52.510 Did you? I think you're too too up. 00:05:48.720 --> 00:05:53.919 Yeah, I had to suck it up. 00:05:53.919 --> 00:06:04.160 I never thought I would be sucking a Easter egg at work. Yeah, I got paid to 00:06:00.080 --> 00:06:06.160 suck it. So, I'm a 00:06:04.160 --> 00:06:10.400 Okay, Dennis, don't let it hit you in the face. 00:06:08.960 --> 00:06:16.440 Oh, no. Dennis, did we actually hit you? 00:06:13.440 --> 00:06:16.440 Dennis. 00:06:18.880 --> 00:06:27.280 Dennis. Just kidding. 00:06:24.479 --> 00:06:33.840 Dude, do you see how fast that came out? Hello. The pingpong ball is the thing to 00:06:30.000 --> 00:06:36.080 shoot. That thing went the ping pong 00:06:33.840 --> 00:06:40.240 ball is the answer. Oh, 00:06:38.000 --> 00:06:42.160 the the pinhole here. How did I get the ping pong to shoot out? So, where is the 00:06:41.520 --> 00:06:45.160 ping pong now? Here. 00:06:46.400 --> 00:06:51.479 What? Should I blow it back? Yeah. 00:06:51.840 --> 00:06:57.059 That noise was awful. 00:07:06.479 --> 00:07:09.479 Wowing. 00:07:09.919 --> 00:07:16.479 Okay. Did it not shoot out that one time? Yeah. 00:07:14.639 --> 00:07:21.039 It didn't even break it, did it? That gets serious sucking pressure. 00:07:19.599 --> 00:07:27.139 Oh, wa. It broke. 00:07:27.360 --> 00:07:35.699 Okay, let's shoot the tomato. 00:07:35.759 --> 00:07:46.720 Did it work? Just eat it. 00:07:46.720 --> 00:07:53.599 Wa. It didn't blow it up, but it did 00:07:50.400 --> 00:07:55.759 shoot the out of it. I'd say that was a 00:07:53.599 --> 00:07:59.270 win. So, Dennis, here you can have your you can have your pop, your celebratory 00:07:58.080 --> 00:08:04.319 pop. Oh, 00:08:02.879 --> 00:08:09.039 thank you guys for watching channel. Super fun.
