This micro-instrument was made from silicon. Each of its strings measures about 50 nanometres, while the thickness is 100 atoms. Despite its tiny size, it was manufactured using the top-down technique. Physicists at Cornell University (New York) have used a laser beam to pluck the strings of the smallest guitar in the world and managed to produce a particularly high-pitched sound of 40 million Hertz.
