Tennis Ball Bomb Ingredients: * Tennis (or racquet) ball * Strike Anywhere match heads * Gunpowder (if you're really adventurous) * Duct tape Instructions: * Cut a SMALL hole in the tennis ball. * Cut off a bunch of match heads and fill the tennis ball with them * Duct tape the tennis ball so that the match heads won't fall out, and so the ball is secure. * Throw it at something. When it hits, the match heads will ignite and all burn. Modifications: * If you fill it 1/2 with gunpowder first, then add the match heads, it will cause a massive explosion when it ignites! Be warned, if it is shaken suddenly, the matches can ignite in your hand, thus exploding the gunpowder early. I once dropped a box of strike anywhere matches on a table and the all ignited within seconds. If gunpowder had been in the box, it would not have been a pretty sight.
