@Butrflynet,
Benjamin Franklin invented the "Glass Armonica" which is based upon the wineglasses with water in em. The armonica is a wheel with a number of crystal bowls that are strung on a rod. The rod turns by a mechanism and the bowls are immersed in a shallow pan of water. The player merely allows his fingers to run along the edges of the bowls as they turn and the music happens. Its a very ethereal sound , someone who is skilled at the instrument can make beautiful music that sounds like a cross between a harp and a theramin.
