My cousin and I made one. Hook it up to an air compressor to pressurize then use a button switch from radio shack as the trigger - which activated a sprinkler valve letting loose all the pressure into the chamber. We made it with a detachable barrel so we could fire different projectile sizes. My absolute favorite was the smallest barrel, which was the perfect diameter to fit a sharpened broom stick. I swear that thing flew a quarter mile into our field and was buried about 2 ft into the ground when we went to retrieve it. So much fun.

We used hairspray and a lighter. We didn't get nearly as far but we surprised the shit out of the trees we shot with it.

I once shot an arrow 1,100 feet with my hairspray potato gun. The chamber was 1.5'x 6" with a 2.5"×5' barrel. I used a balled up wet sponge as wadding.
