The Piano set is a magic instrument that turns fruits into real music with the sound of piano, xylophone, violin and guitar. The magical instrument can teach children about conductive materials and not only works with fruits, but also water, the human body, or metals at the touch switch. An additional feature is that multiple players can hold hand-in-hand to create together different sounds.
