You are in a concrete room. There is a steel pipe 25 cm in length cemented into the concrete floor. The pipe protrudes about 15 cm. A ping pong ball is dropped down the pipe. There is a fraction of a centimeter clearance around the ping pong ball and the pipe. Your task is to get the ping pong ball out ofthe steel pipe undamaged. The only items that are available are a wooden ruler, a ball of string, a pocket mirror, a paper clip and a small magnet. Since nothing else is allowed into the room, how could you get the plastic ping pong ball out of the steel pipe?
