I made this gun a couple years ago when I was in high school to be able to shoot teachers at the front of the bus with paper balls, but I have since grown up :wink: .
I started off taking apart one of those big air powered streamer things that you get at firework stands around the 4th. This would be my combustion tank. I then took apart a grill lighter and saved the piezo electric igniter, and the nipple that connected the lighter in the handle, to the tip of the lighter. I also needed a 3/4" pvc end cap and threads, and finally a Bic pen for the barrel and ramrod.
I took my Dremel tool and cut a hole in the end for me to epoxy my cap and threads. I also used it to drill into the side for the ignition points, and butane nipple.
I then epoxied the igniter and wires for the ignition point onto the side of the tank, along with the nipple.
As for the barrel I took and cut off the narrow end and filed the edges to a point, and put electrical tape on the end to wedge it in the tank.
After that was completed I had my gun to shoot paper and potatoes.
I later made a dart out of sharpening a nail to a point and wrapping tape around the end to make a seal. Works great!

Here is the inside of the tank, you can see the ignition points on the left and the butane nipple on the right

wow, your teacher must be retarted, my various little pill bottle minis sound like a party popper going off, especially if the ammo is a tight fit. i did bring my pneumatic to school in 7th grade to shoot soda cans across the practice fields during our shop/physcics class.

Thats because you were talking about shooting spuds at someone with a bigger gun, which could cause serious injury

I sometime take my miniature catapult to school and shoot peanuts around :D

Nice cannon btw :wink:

My mini just blew up in my hand. :cry: .Anyway, thats a nice mini i like it. It has style and it looks awesome. BTW, have you ever been zapped by the wires on the outside? (i have. :oops: ).

I like your ammo its devilishly evil.how far can you get the dart? and how much power?
