A Kuel Bomb Ingredients: 1. Glass or plastic coke bottle. 2. 1 can of CRYSTAL draino, NOT LIQUID Draino! 3. Some aluminum foil. 4. A cup of water. Preparation: (Make sure the bottle has a cap!). Fill the bottle 1 fourth to 1 thirds of the way with CRYSTAL draino. Get the aluminum foil and make about 7-10 balls of it that will fit into the bottle, then put them into the bottle... Now, get the cup of water and pour it into the bottle. After this is done, quickly screw the cap on as tight as possible. Now shake the bottle, throw it, or whatever, just so the contents get mixed together. What will happen is it will get so hot in the bottle that it will have to blow up... With a plastic bottle you have about 15 seconds before detonation, with a glass bottle you have anywhere from 30 seconds to a minute... Have Phun...
