o if you guys want a deadly mix. acetylene is deadly if put in pvc and safer in metal but i still go to the underground method.

i have a :idea: for a gun that will have a perfect mix and can control the amount of mix. this is by taking a T connector for water and the chamber then goes to the barrel. in the water will be two electrodes called an anode and cathode. just so u don't have to wait so long use a car battery or two....
