in this case, were the 99% and youre the 1%. ever wonder about that? I know a guy who had a fan going and there was a random spark or something in the fan half way through cooking the butane off that caused it to blow up. his pants melted to his legs and it lifted the fucking ceiling off the house, cracked all along the top of the walls.
ive blown it up before making it outside, with the door open a crack and about 15 feet away from the door.
learn from others mistakes, not your own. it happens faster than you can think "oh fuck he was right, I should have done this outside, now I got an explosion and a dish of butane with a flame 8 feet high in my kitchen and my skin burns so fucking bad I want to die"
some people dont know butane sinks. put a fan at head, or waist level and its very ineffective.
some people dont understand how to exhaust a room properly, and have adequate intake air coming into the room to help move air.
some people dont know the current wind direction and make it near an open door with a fan. thinking that the air is going out, but really its all just coming right back into the house.
its because of fucking idiots that make it indoors and blow themselves up, that making BHO is classified in the same categories for some people as making meth. can get 15+ years for making BHO in some places. wouldnt be like that if we all made it properly outside and werent blowing apartments up and burning houses down because were lazy or too pussy to go out in the cold.
