Object #1 - Best Guess ANSWER

CORRECT!

The glass harmonica is a type of musical instrument that uses a series of glass bowls or goblets graduated in size to produce musical tones by means of friction (instruments of this type are known as friction idiophones). It was invented in 1761 by Benjamin Franklin and produces sound similar to the glockenspiel.
