1. Get a coke bottle & fill it with gasoline about half full.
2. Cram a piece of cloth into the neck of it nice and tight.
3. Get a chlorine tablet and stuff it in there. You are going to have to force it because the tablets are bigger than the opening of the bottle.
4. When it hits the pavement or any surface hard enough to break it, and the chlorine and gasoline mix..... BOOM!!!!!!
