but since we're talking about homemade explosives....there was an upperclassman druggie in my alg. 2 class, my sophomore year, that told me about some lava kinda shit...you mix some crap together, and then you have to light it with a big flame..like a jet lighter....i think that's what he called it.... and this thing would heat up to really high temperatures and just burn through things like hot magma...i dunno if it was the crack talking, but i've heard from several people ater that, that there is such a thing...and its all made out of homemade appliances...
