So my friend and I finished our potato gun today... Not sure how fast it shoots, but it could definitely kill...

THESE ARE THE TWO BEST SHOTS WE MADE! COMING ON SEVERAL HUNDRED MILES PER HOUR!

thats cool...how long did that take to make?

Psh, nitrogen powered is the way to go. We had one that shot golfballs 4 miles (theoretical distance, 2 miles actual). I'll get a video up later. Still, yours is cool.

Dude, do you have plans for that?!? My compressed airgun has sorta reached it's limits(pumping a 5 gallon 135psi tank with a bikepump is tiring)

The potato cannon is also most awesome!

Well, between cutting the pieces and putting it together, it took about 2 hours TOPS. Plus paint. Including going to the store, maybe 3 hrs. We did it over 2 days spaced months apart, today we finished it (2nd day). We've been using 2-5 quick sprays of axe deodorant spray (some of the later ones were louder than gunshots - videos do no service!). We fired one straight up, and it ended up 500ft or so down the road at a bible college... I figure it's pretty well made and works great for a simple combustion potato gun.

how does one of these guns work?

i have some low ID steel tubes in my office. old samples never send to the customer. about an inch in inner diameter. a battery might fit in there ....an evil plan starts to rise in my mind

how does one of these guns work?

There is the larger tube, 4" or 5", on the bottom of the barrel. At the very bottom is a screw cap where hairspray, or any other flamable gas can be sprayed in, then the cap is quickly put back on. Use a barbaque sparker such as he did for the spark to ignite the gas. before you ignite it though, you shove a potato down the barrel. juicy ones work the best. i like to bevel the edge at the top of my barrel so its sharp enough to cut the potato as you shove it into the barrel...cutting it to size.

they're lots of fun, i take mine out on my boat to the river in the summer. shoot at skiers or idiot boat drivers that piss me off cuz they cant drive or dont pay attention

When I was a teen we used to make them out of tin cans. 3 or 4 tin cans with both ends cut out to form the barrel, then 2 tin cans with bottoms intact but about 6 nail holes punched in one bottom to form the ignition chamber. We used lighter fluid as the fuel and a small hole in the side of the ignition chamber can to light it with a match. The whole thing was held together with DUCT TAPE!

Sometimes the duct tape blew apart and you got a little flash burn on your hands! [fake]

At Halloween we used it as a rotten tomatoes and dried corn motar

I'm not that old, (or maybe I am) beer used to come in steel cans, not aluminum. We'd use an electric can opener to take the top and bottom off of 4 empty cans, then we'd take the fifth can and use a can opener to cut a bunch of triangles around the top and put a small hole in the bottom. Once everything was ready, we'd solder them together. A couple of squirts of lighter fluid... shake it to disperse the fluid... toss a tennis ball in... and touch it off with a match. The cannon would get warm with use, so each time you squirted fluid in, it would vaporize much better. The more you used it the more effective it became. Ahhh the good old days!

i built a couple. Mine was smaller and shaped to be easier held, still powerfull enough to desintigrate a potato. used to shave golf balls down, wrap in tissue and see how much i could dent a mailbox.... paid for it though by wrecking my mercedes sliding off a muddy road one night.

hmm, brings me back to the days i did this type stuff: crazy
