  6. i made one from an empty 2 liter and a steel fence pole ductaped toghether. id just fill the empty bottle with propane from my stove for few seconds (i figured out how long u have to hold it over the stove to get the right mixture) then id attach it to pole barrel, then i stuck a like lighter igniter (u kno the gun type ones), extended the wires and just stuck the end in the bottle throo a hole i made.its really cool but really simple i just tilt it up agains something. its liek 2 feet long but shoots like 70 yards. and also, pack the projectile in there tightly, the tighter it is the more powerful cuz theres more pressure and itr combust faster. and also- no more mentioning skool.. ugh
