Ingredients:
Strike anywhere matches
A tennis ball
A nice sharp knife
Duct tape
Break a ton of matchheads off. Then cut a SMALL hole in the tennis ball. Stuff all of the matchheads into the ball, until you can't fit any more in. Then tape over it with duct tape. Make sure it is real nice and tight! Then, when you see a geek walking down the street, give it a good throw. He will have a blast!!
