Potato Cannon

Lord_Piot and another friend of mine came over to my place after school today, and they convinced be to dig my potato cannon out of the garage. For those who don't know what a potato cannon is, it's assembled using PVC piping and ignited using hair spray or something close to that. Anyways, i fixed it up a bit and took a test fire...and broke a fence board in half! It's the shit!

Anyways, any one else ever play with these things?

OHHHHHH man potato guns are sooooooooo cool. IF you use enough hairspray they can go sooooooo far. The best is to shot them at cows from like 200 meters away.

I've been planning to make one for a while. gonna make one with 2, 4inch wide pipes for the spray and then make it go down into a a 1.5 inch wide barrel. it's gonna be so wicked.

and yeti I hear that they're amazing at night.... it'll shoot a flame out.

i did it the most dangerous but effective way. I drilled a hole through the chamber (keep in my mind that my chamber is a 'Y' tube, which keeps the majority of the flame away from the igniter) and stuck a barbecue lighter though it, used duct tape and silicon to secure it well. The problem with this is that there is a breach in the chamber now so it may be prone to failing, but so far it's been okay.

yea we used ether in mine and it didn't work as well as hair spray.... the hair spray fucks up the threads though.... meh. ummm We shot a kid with ours once..... he was like a couple hundred feet away.... and he tried to catch the potatoe.... and yea... he had a very big welt on his stomach. He wasn't the smartest kid.... it was hularious though.

i'v built tons of them, they rule. try putting dryer lint in the chamber and sparking it without a potato, it shoots out 10 foot blue flames lol. you can also shoot out other things than potatos if you put stuff in a dixie cup and put the cup in the chamber

yeah my friend had a sick one last year, but then on 4th of july we were sorta shooting it at boats and running around with fireworks and the cops showed up, and they took it away because they said it is classified as a bomb or some bullshit like that

I used to have a little potato gun that I bought in canada and me and my cousins used it to shoot a bat up a drain pipe. That was a fun toy till it broke!

last year my project for chemistry was to build one. it wasnt that big, 6 feet long or so... but i think we shot around 200 yards. we had blue flames come out of it a few time also.

i once had two of my guns down at the waterfront and the cops came and said they were gonna take our cannon cuz it was classified as a firearm...but i owned them when i started talking about muzzle velocities and the such, so they just left :-)

I have tried to make one, but abondoned the idea. I wouldnt feel safe making a gun out of PVC pipe though. It would have to be metal.
