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