yup? we make them at work all the time. since i am a plumber its easy acess to material. only difference is we use acetalyne gas....... it sounds like a missel. puts a potato through a house in no time. just please be careful. we had an accident with it one day. my helper was holding the barrel away from him, and another kid was filling the chamber with gas. he lit it and BOOOOM it exploded into millions of pieces. and i saw it in slow mo. it was awsome. luckily nobody was hurt.
