cool but i dont know i think just pure potassium nitrate and some black powder to set it off

Well It all depends on what kind of explosion you want, personaly PBC can be ALOT better if your trying 2 kill a mother fucker (dont try this) all you do is use some cheep tape and tape nails, skrews, marbals, glass, ext.... light the bitch, it does more of a poping noise like some1 els said but it will blow the pipe away much faster and easier so that the skrews and nails adn w/e will go and impail someone... DONT DO THAT THOUGH THAT WOULD LEGALY MAKE YOU FUCKTARDED!!!

OK new rule:

YOU ARE REQUIRED TO BE WITHING A WEEK (OR THE SAME F'IN PAGE) AS THE PREVIOUS POST!!!

I like that rule

omg even IM not this stupid (post points ^^)

bbs, broken glass, gravel, marbles, etc
