Different sizes of clay flowerpots make amazing bells. Tie a knot in one end of a rope and slip the other end through the hole in the bottom of a flowerpot. Tie the rope to a rolling coat rack, broomstick, or bar. Use a cork glued to the end of a chopstick as a mallet and play "Where Have All the Flowers Gone." Try holding on to the pot when you strike it and see what happens when there is less vibration.
