Boom! The classic potato gun harnesses the combustion of flammable vapor.

<div align="center">POCKET ROCKET

I finished my new combustion launcher, all out of black iron piping, its called the pocket rocket, and measures only 13 1/2" long. a spritz of cologne sends wire nuts flying. the parts from cap to barrel are 3/4" endcap, 3/4" 6" nipple, 3/4" coupling, 3/4"-1/2" reducing bushing, and a 1/2" 6" nipple.

it took me about 5 minutes to put it together, but about 45 minutes to cut out the letters from tape.

EDIT: also how much fuel should i use? i get it right every 4 tries but i want it perfect. i use butane.

try some wire nuts or AA batteries, i use a small spritz bottle of cologne to power it, try putting a ligher in the open end and press the button but dont spin the flint, so just the butane comes out

How did you get it to arc in the chamber? A wire inside the pipe or something?
