In pod 5 we counted down the Top 5 objects shrunk down to nano-scales and here is our winner: the nanoguitar. It was made back in 1997 by a team at Cornell who sculpted it out of a single crystal of silicon on an oxide substrate. At 10 micrometers long it truly is the world’s smallest guitar and has six strings about 100 atoms wide, which when plucked using a laser beam produce a note 40 octaves above human hearing.

Hear about the nanoguitar and the rest of our nano-object in Pod 5.
