Glass harmonica

A glass harmonica is a special musical instrument that is made of glass. It looks like a bunch of glass bowls stacked on top of each other. The bowls have different sizes and they are all put on a rod that spins around.

To make music with a glass harmonica, you have to wet your fingers and touch them to the glass bowls as they spin around. This makes a beautiful sound that can be very calming and relaxing.

The glass harmonica was invented a long time ago by a man named Benjamin Franklin. He was a really smart guy who did lots of other cool things too. He loved music and came up with an idea to create this amazing instrument.

Glass harmonicas are not very common these days because they can be expensive and fragile. But some people still enjoy playing them and listening to the peaceful and soothing sounds they make.
