NOT BEEN TESTED DO NOT BE A DUMB FUCK EXPECT IT TO FAIL AND BE HAPPY IF IT DOSNT. TAKE PRECAUTIONS AGAINST SHRAPNEL AND NOISE. also, know your local laws about shit like this and please don't aim at pets, wildlife or people. not expecting anyone to want this its just the easiest way of saving the file but in case you do 1 drill a small hole in a standard bottle cap 2 load something which fits snugly in the barrel (standard nerf dart should fit) 3 fill the space in the back with gas from a blowtorch(the blowtorch should ensure a good ratio of gas to air) 4 screw on the modified bottle cap onto the rear of the launcher 5 light the chamber through the hole in the cap a better way to light it would be to model in a hole for a bbq lighter and seal around it with silicone, but I don't have a bbq lighter at the moment to measure so if you want a hole then just drill one yourself or ask me for the file
