i have found alot of ways of making them what is the best way

------------------
you should learn to listen to the rantings of the crazy

take a 20 oz bottle. fill it about 1/5 of the way up with water. put about 5 or so table spoons of sredded aluminum foil in there. then add in about 2 tablespoons of crystal drano in the bottle, cap, shake a little, and throw it. hydrogen will form inside the bottle, eventually bursting it.

if using liquid drano, just fill up the bottle 1/5 of the way with the liquid drano (dont use liquid plumr, it wont work). then add like 4 of so tablespoons of shredded aluminum foil inside, cap, shake, and throw.

the amounts dont matter that much, keep the liquid amount the same, but you can play around with the foil amounts.

oh and dont ever touch the drano. itll burn your skin pretty bad.
