Did you know that the world's smallest guitar was created right here in Upstate New York? It was designed in Ithaca at Cornell University. According to Cornell, the guitar was carved out of crystalline silicon. It's no larger than a single cell. Now this guitar was The "nanoguitar" was made for fun and science. The guitar has six strings, each string about 50 nanometers wide, the width of about 100 atoms. Does it actually play music? If plucked — by an atomic force microscope, for example — the strings would resonate, but at inaudible frequencies. The entire structure is about 10 micrometers long, about the size of a single cell."
