I love fire.
Anywho, empty metal can (like one you'd put writing utensils in) + filled 1/3 with gasoline + 6in. by 6in. cube of styrofoam + fire = napalm. >:D
Instuctions:
1. Tear off chunks of styrofoam and put them in the can of gasoline. They will "dissolve." Use a stirring stick to speed up the process.
2. Once all the styrofoam has been dissolved in the gasoline, stir around for a couple minutes.
3. Pour out some onto something non-flammable (rocks, cement, metal, etc.)
4. Light and enjoy.
WARNING: Do NOT attempt to put out napalm fire with water. It doesn't work. Use dirt or flour. Also, avoid breathing the thick, black smoke that arises at all times. It is fairly toxic. It goes without saying that this is to be done outside and away from flammable material (plants, houses, people, etc.).
