If the nossle is wide and there is exact flow of air there is a posibility for it to turn in to a jet engine... :roll: It happend to my first gun(for a few seconds), but notting spacial, if the chamber is from glass and type.My edvise is to use a glass chamber and something around it so if it crack there won't be any shrapnels.

Doesn't alcohol exhibit some polarity on the molecular level, but evaporate at room temperature? And it would be impossible for it to all light at once, the chamber would have to be overpressurized.

all it is is a bottle, a straw, one way flow valve with air hooked up for airing out the chamber, and something to load ammo. you pour alcohol in, the fumes are there, you click the sparker boom, air comes in, airs it out, more fumes, and boom, etc.
at least I think thats how it works
