A steel pipe is embedded in the concrete floor of a bare room, as shown below. The inside diameter is 0.06" larger than the diameter of the ping-pong ball (1.50") that is resting at the bottom of the pipe. You are one of a group of six people in the room, along with the following objects:
100 feet of clothesline A light bulbA carpenter`s hammer A chiselA box of Muesli A fileA wire coat hanger A monkey wrench
List as many ways as you can think of (in five minutes!) to get the ball out of the pipe without damaging the ball, the tube, or the floor.
