Ben Franklin's Amazing Musical Instrument

Now considered one of the first musical instruments invented in Colonial America, the Armonica is a little known invention of Benjamin Franklin.  It is based on the principle of creating a musical note by running a dampened finger around the rim of a crystal glass or bowl.  Franklin often brought the armonica on his travels and noted that: "Of all my inventions, the glass armonica has given me the greatest personal satisfaction."
