Glass Harmonica

Written by Xavier Gouchet - 20 march 2015 - no comments

I already knew about musical glasses, and how one could play music on crystal glasses filled with water. It's one of Christmas tradition at my wife's grand parents to play with the glasses during dinner.

Anyway, I just discovered that Benjamin Franklin invented a Glass Harmonica in 1791, using a turning axle on which he put severall bowls of varying size.
