I've got just what you need.
First you should get a three liter bottle.
Second you'll need some fine grain aluminum powder.
next you'll need some muriatic acid.
next take the muriatic
acid and boil it to concentrate it.
make sure the area you are boiling it in is well ventilated.
next poor the concentrated muriatic
acid into the bottle.
next take the aluminum powder and rap it up in a couple of napkins.
don't make the ball of napkins with the aluminum powder in it to big to fit in the bottle.
next put the ball in the bottle and place it where you want to cause some damage and run like hell.
in a few seconds you will hear an ear shattering boom and whatever you put the bottle in will probably be gone or greatly damaged.
the stuff in the bottle will also leave a fine vapor that will eat the paint off of cars.
