I like to mess around with potato guns occasionally. I made one out of steel that runs on air, its very clean and a bit more powerful than regular hairspray powered potato guns (also more reliable.).

Anyone wanna know how to build a hairspray one? I could help.

The only potato cannons i've seen run on huge co2 canisters.

how would a hairspray one work?

Load potato... spray a shitload of hair spray... cover the lid, flick the ignitor... WOOSH

Yeah, what Ergot said. You use a BBQ ignitor (causes a spark) that ignites the hairspray, causing explosing (and expansion) that pushes the potato out.

Crazed, mine runs on an air compressor.

Why not just use propane?......

me too, sometimes?
I guess if I were in a duel I'd rather have a bullet shooting gun than a potator shooting gun.

You're trying to launch a potato... not a bowling ball.

mmm, is propane cheaper or more expensive?

couldnt you just have a smaller chamber & then put a small amount of propane in that to launch?

Propane burns too hot, and might create too violent of an explosion, not sure.

Personally, I tend to stay away from shrapnel, or the possibility thereof. =)

Will this potato gun be mounted on your car?

but if its made outta steel pipe

If it's made out of steel, you'd really have to worry about shrapnel, wouldn't you?

not if its thick enough.
Also, if you put the combustion chamber inside of another containment thing then the shrapnel will hit that & not your eye

Good ideas, all. Most hairspray cannons are made of PVC or ABS plastic. Steel would be much less likely to fragmentate, but if it did... Ouch. I usually dont take risks like that. When I was testing my air powered steel one, I hooked it up to the compressore (at 0 psi) and put it outside on the left side of my garage. I then turned the breaker to the garage off, turned the compressor on, went to the right side of my garage and flipped the breaker back on. You can call it overcautious, but Im still alive. =)

When I lost the power cable for a pair of speakers that were pieces of junk anyhow, I used my universal power cable thing, set it to 30volts, and hooked it to a power strip. Flipped the power strip on, BOOM. I'm also alive.

I guess I could see how that could possibly be related.. in that you are still alive. And so am I. Anything other than that I might be missing?

Obviously you're not retarded like Joe. Joe's incident fried half his brain cells. Now he only has 1.
