Douchenator Commercial

This is a commercial we made for our TV class. We had to call it APOL cause I don't think we could get away with "Douchenator".

The ending of the comercial was for some reason funny to me. While it said at the end "performed by trained professional", it somewhat looked like a random dude who got blasted in the back of the neck while he took a pee.

I like that design. The pressure chamber is very small (providing a quick fill with a pump), and the ball valve is very simple, cheap, and opens fully (unlike a sprinkler valve, which opens quickly but has a lot of restriction)

What pressure were you using when you launched that stuff?

I have a very large 10 foot, 4" PVC laucher right now, but I want to build another one small enough to carry with me and that doesn't take a half an hour to pump up with a 12v car air compressor.

My favorite part was the timing in the video splicing of all the different stuff launched. It was cool watching so many lauches in such a short period of time.

We had it on 50-70 PSI, not too high because we wanted the camera to be able to see the objects clearly as they left the barrel.

I REALLY like that thing. With a small pressure chamber, it seems like it wouldn't take very long at all to fill, and it seems that the slow timing of a ball valve is outweighed by the lack of restriction. This is going on my list of projects. (It'll be my third launcher / potato gun. The first was combustion-powered, but I could never get the mixture right. The second was pneumatic, but it's too damn big.)

Our original one was actually about half the length of the current ones. It broke a whole ago, and we wouldn't have used it anymore anyway due to the barrel being too short. What I like most about the current design is that you can easily adjust the ratio of the barrel and pressure chamber to your liking, without causing too much difference in power and range.

It takes roughly 10 seconds to pump to 50 PSI, and about 20-25 to get to 80. We also prefer the in-line design vs an over-under because the straight line from the pc to the barrel allows the air to blast out directly.

Question...What are you using as padding for the object you're launching? Does it affect the speed dramatically?

DX · Post by DX » Fri Apr 21, 2006 1:05 am

We use an upside down Pringles can as the wadding, and it forms a near perfect seal. We used to use tennis ball cans, but we found out that the Pringles cans work even better. Since the seal is better, the objects launch farther. Without the wadding, the object won't go very far, and often doesn't even shoot. So yeah, it affects the speed quite a bit.

Is there a method that allows for padding integrated into a WBL, i.e. a piston inside the barrel? By the way, one of the numerous reasons why I detest WBLs is that you have to deal with padding all the time

.

The problem with a piston is that, unless lubricated (if possible), it will probably absorb some of the force.

Tell me if there's a better thread to post this in, as I support the grouping of posts and the merging of threads, and because there are so many WBL threads floating around. In my mind, there only needs to be one thread.

This is, however, the Douchenator Commercial thread, which is different from a general water balloon launcher thread. Even in a regular one, stuff goes off topic, but that happens regardless of the precautions against it.

I did once consolidate threads to make one giant one two years ago, which is the K-mod topic, but I've found that people prefer multiple topics if their subjects at least start out with different ideas. [Such as here, with different launchers]

I use motor oil in my pneumatic launcher.

What size PVC are you using for the douche?

Motor oil...wouldn't that leave some residue within the barrel? It's not too big a problem, but the balloon will be touching that stuff.

I've been thinking much more about the use of a piston in a WBL, and I think it would be quite practical. In addition, the piston can have a hollow cylinder-type cup to hold the balloon, preventing contact with the motor oil/other lubricant (minor point) and slowing/harmful friction with the barrel (major point, I think). I haven't looked too carefully at too many WBLs, so maybe the water balloon doesn't touch the barrel anyway...I don't know

I don't launch water balloons. I find that a standard can (from soup or vegetables or whatnot) fits 3" PVC well, and it's very good with a single layer of paper towel wrapped around it soaked in oil.

I watched this a while ago but forgot to reply - very funny, and interesting to watch.

I'd like to do something like that for Cerberus when I've built it, but I have no editing software to do it with.
