The world’s smallest guitar is about the size of a human blood cell!

The tiny instrument was carved out of crystalline silicon by scientists at Cornell University back in 1997. This “nanoguitar” is just 10 micrometers long, with six strings that are each 50 nanometers, or 100 atoms, wide! If the guitar’s strings were plucked using an atomic force microscope they would make a sound, but at frequencies that cannot be detected by the human ear. Anyone who is sad about this will have to track down these researchers to get them to play you the world’s saddest song on the world’s smallest violin.
