Riddle: You are in a room that is an 8x8x8 perfect cube. There are no windows or doors. (Don't ask me how you got in there). In the center of the floor there is a 12 inch pipe that is sticking 6 inches out of the floor. In the bottom of the pipe is a ping pong ball with the diameter that is one millemeter smaller than the inner diameter of the pipe. You have a 12 inch piece of string, a match, a magnifying glass, a 6" ruler and a paperclip. How do you get the ping pong ball out of the hole?
