Benjamin Franklin: Prolific writer. Founding Father. Inventor. Creator of a killer instrument? The Glass Armonica, more or less a series of singing water bowls with haunting melody, became a popular instrument for a very short amount of time. But by 1830,  it ceased being played entirely. Was it because its strange harmonics were making people ill? Or maybe it was just very fragile and hard to carry around? Music: "Medicines" by The Taxpayers https://taxpayers.bandcamp.com/
