This video demonstrates the easiest and fastest smoke bomb that a person can make. Supplies include aluminum foil, standard ping pong ball, a pen or pencil, and a flame lighter. Wrap the ping pong ball with foil, being extra careful not to tear the aluminum foil. Use the pen to create a funnel shape with the foil. Remove the pen. Now, light the bottom while holding the top. The smoke is toxic, so don't inhale. Make sure the smoke bomb is on a non-flammable surface as it gets very hot. Also, when the smoke is done wait until the bomb has cooled before picking it up and throwing it away.
