Create music on your own hand! When you pound the colored Palm Pipe into the palm of your hand, it disturbs the air molecules inside the tube. The action of these molecules creates the vibration that becomes the note you hear. Gather a group of friends and put on a concert! Set includes 8 music pipes, each with a different color and length, which create eight different notes (C, D, E, F, G, A, B and C). Also comes with instruction cards. Designed for ages 4 and up.
