All right, welcome to Channel Super Fun, where today we're going to be making a wicked vacuum cannon.
0:09
So, we originally 3D printed these special ends for this PVC pipe that
0:13
we're going to be shooting the stuff out of.
0:16
Dennis, we need things to shoot and we also need things to shoot at. We have
0:20
wood. What's ud? Piece of wood. Okay.
0:24
What a joke. You're a joke. All right. Well, the way that this thing
0:28
works here, for those of you that don't know, is there's a tube here, right? So,
0:34
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
0:38
both ends. We're going to put something in beforehand. Then, we're going to suck
0:42
all the air out of this darn thing through this tube and this vacuum pump
0:45
through this hole right here. It's going to have a lot of negative pressure in
0:49
there. And then when we pop the end with the tape on the other side, it's going
0:53
to let all that atmospheric asm atmospheric pressure run into this and
0:59
shoot that thing out the other side real fast. Supersonic speed. That's what I
1:03
mean. So, we're going to first try and shoot something at that styrofoam. See
1:06
if we can mess it up. Dude, this thing looks pretty good. This is just like paper tape or
1:11
whatever. I'm just going to put it on here so the edges are smoother so this thing rips through there harder.
1:20
Why is there an egg frying on your hand? I'm on fire.
1:24
This is the best tape to use cuz it's pretty strong. So, you just put it on
1:27
there. You make sure it's got a nice seal. Not like the Singer seal. Not like
1:32
the animal seal, but just like a nice It's touching all the edges. And then
1:36
you want to come over here and do the same thing to this one. Woo. Looks like
1:42
it's lined up pretty good. So, we're going to use that as our thing to pop
1:45
the other side. Okay. Okay. So, this part is kind of dangerous. So, make sure
1:49
nobody's standing in the trajectory zone. Don't stand in front of there.
1:52
Stand to the side. Keep it alive. Ride
1:55
or die. Dennis, do you want to do the honors?
2:00
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
2:04
whole thing? I I know. I don't believe you, dude. Trust me, Dennis, I give you the honors
2:08
of turning the pump on. How about that? Where's this week? Let's do it. So, we got the pump
2:12
tension.
2:17
What else should we shoot? We should shoot something else. Dennis, I'd like you to stand in the front there.
2:21
Lower your face. No, it's just for testing. It's just for testing. Do you need anger management, Dennis?
2:26
Go.
2:30
Wa. Okay, turn off. You need to go through here. We need a ping pong ball.
2:34
What is it? A metal slug.
2:38
Maybe. Let's try it. Wa.
2:43
You shoot it. It It skipped it. It did a high jump over
2:46
it. Dennis, what can we shoot out of it? Dennis, I need your help for once in my
2:51
life. You need to help me look for things like this.
2:58
Wo, that's really dirty. I've never hit anyone with this.
3:02
Answer it. Just showering. You know what hurts? Ow.
3:06
That's That hurt. Yeah, it's metal.
3:10
You can't whip me with some metal. Okay, Dennis, can you collect a lot of little
3:13
rocks? I hate nature. So much dust and leaf
3:18
dros. Are this good? Not enough. We need more.
3:23
Collect more. There's a hole.
3:28
You can't see neighbor.
3:31
You can kind of just check them out. Why are you checking out your neighbors?
3:35
Okay, we need to break something. Wa! We can't get anything to really
3:40
work. That one was heavy, but it still just bounced off there. I think what I'm
3:44
going to do is put I'm going to try and shoot this now.
3:48
This will be our shotgun casing. These will be our little fragments.
3:56
Except we don't have Dennis anymore. Dennis had to be uh deported. Sorry
4:00
guys. The government came today, picked him up, scooped him away, and said,
4:04
"You're never coming back here." So, we said, "Can we at least keep his car and
4:08
all that sort of thing?" And they said, "Yes, you can." And uh so that was that.
4:11
That was the end of Dennis. So RIP Dennis. He's going back to Mongolia. And
4:16
uh we'll see him in another life. So I hope you guys don't miss him cuz we
4:20
certainly don't.
4:23
Oh no. It sucks. Didn't even break the
4:27
pop can. How did it come out so much harder last time?
4:31
Okay, so I think I'm going to try and screw this in. So now this is going to
4:35
be our bullet.
4:39
I think it was too big and heavy. This might work better. It's just a piece of
4:43
tube with some metal at the back.
4:46
We're doomed. It's never going to work. I actually don't know what to do
4:49
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
4:55
fire out of the vacuum cannon properly. It hardly even shoots anything. So,
4:59
let's go find some more to shoot. Okay,
5:02
so we got these like Easter I don't know what the hell these are,
5:07
but they like just fit in here. Oh, would you look who back?
5:13
The Eastern Devil. Stand in there. I'm going to shoot you with an egg. It's
5:16
very soft. Don't worry. Seriously, this is what most people have to do for
5:21
their citizenship. I'm not joking.
5:25
Read the handbook. Yeah. Oh,
5:30
okay. Hey, I'm actually glad that you're back, Dennis, cuz I didn't have a little
5:33
to help me for a while.
5:40
Okay, let's see how far this thing can go. Fire.
5:45
Did you? I think you're too too up.
5:48
Yeah, I had to suck it up.
5:53
I never thought I would be sucking a Easter egg at work. Yeah, I got paid to
6:00
suck it. So, I'm a
6:04
Okay, Dennis, don't let it hit you in the face.
6:08
Oh, no. Dennis, did we actually hit you?
6:13
Dennis.
6:18
Dennis. Just kidding.
6:24
Dude, do you see how fast that came out? Hello. The pingpong ball is the thing to
6:30
shoot. That thing went the ping pong
6:33
ball is the answer. Oh,
6:38
the the pinhole here. How did I get the ping pong to shoot out? So, where is the
6:41
ping pong now? Here.
6:46
What? Should I blow it back? Yeah.
6:51
That noise was awful.
7:06
Wowing.
7:09
Okay. Did it not shoot out that one time? Yeah.
7:14
It didn't even break it, did it? That gets serious sucking pressure.
7:19
Oh, wa. It broke.
7:27
Okay, let's shoot the tomato.
7:35
Did it work? Just eat it.
7:46
Wa. It didn't blow it up, but it did
7:50
shoot the out of it. I'd say that was a
7:53
win. So, Dennis, here you can have your you can have your pop, your celebratory
7:58
pop. Oh,
