#9 Glass Armonica
The story goes that a love of water indirectly inspired Benjamin Franklin to create this weird musical instrument. Inspiration came from watching a magician playing music with wine glasses in 1757, while he was living in England. While the magician had stroked the top of the glasses, Franklin adapted the idea and arranged 37 glass bowls on a spindle. He found that the larger the bowl, the deeper the sound it produced. All the player does is touch the glass with wet fingertips as the bowls spin around the spindle. It created a sensation in Europe at the time and Mozart wrote two pieces for the glass armonica. Beethoven and Haydn also composed for the instrument.
