ok people im not the smartest person in the world, but i just found out from my chem teacher that pure patassium is highly explosive from water contact, so explosive that you can only touch it with tongs and you cant touch the tongs end with ur hand or else the moisture will explode it, he said in college chem they did a demenstration with it, they used a chunk as big as a paintball and it blew every bit of water out of a 6 gallon tub, also if u do get some of it somehow you have to keep it in an airtight sealed container cause the moisture in the air can explode it.

also he says that a chunk of it 3ft, 3ft, 3ft could level a 3 story building

if someone does get their hands on some patassium and you use it please film it for me, i want to see if it is as explosive if he says it is

oh it's every bit as bad as he says it is.....there's a google video on it, im sure.....just find the video...i dont remember what it was called...
