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

i recently installed a fan into my gun but i was wondering approximatley how long to run it for when im mixing the fuel before the launch. also how well anchored in the chamber does it need to be cause mines in there pretty good but i feel like the combustion will blow it out, thanks

As long as the fan is near the back of the chamber (furthest away from barrel opening) you shouldn't need a super secure fastening of the fan. The air will not suck it out or break it. I secured mine with rubber cement (glue) and my cannon is a 2-3x hybrid. No issues with the fan after well over 1000 shots.
