Have you ever wanted to play an instrument, that didn't require you to touch it at all? Well then check out the Theremin! Invented in 1919 by Leon Theremin
How about an instrument invented by Benjamin Franklin (Yes, THE Benjamin Franklin) in 1761?
The Glass Armonica!
New instruments are being invented all the time. The newest is a "Marble Machine" built by Martin Molin, who also composed the music you hear.
How did he build this? How long did it take? Well, let's find out!
Where did he get his idea? Well, marble machines have been around for a long time. But a group called Animusic made a computer animated music video that looks very similar. It could have inspired the marble machine.
The video that Animusic made, inspired Intel to create the same machine as in the video. It only took them 3 months to build and write the programming!
What instrument do you think could be invented next? Maybe the next one will be your idea!
