Ok guys im planning to get me a stash of some substance that will explode decently that is somwhat safe to keep in large amounts...Im planning to make firecrackers, pipe bombs and anything in between with it... I was leaning toward Black Powder, but flash powder would be more bang for my buck but i hear its tricky to make and DANGEROUS..... Any other recomendations???
Oh and if there is a place to buy black powder at for cheap please tell me cause i looked and i did not find much..

no explosive substance is safe to store in large amounts. for ideal safety avoid storing pre made explosives if possible. try to make substances as they will be used. this should prevent your garden shed mysteriously dissapearing one night only to replaced by a smouldering crater.

wal-mart sells black powder pretty cheap

why are making these things
