1World’s Smallest Guitar: the size of a human blood cell
The Nano-Guitar is 10 micrometers long, about the size of a single human blood cell.
Made by Dustin Carr and Harold Craighead of Cornell University’s Nanofabrication Facility, each of the six strings are 50 nanometers wide, about the width of 10 atoms.
2World’s Smallest Grand Piano: equipped with a 4-milimeter keyboard
Created by Sega Toys Co. on 2006, the world’s smallest grand piano is equipped with a keyboard with mere 4-milimeter (0.16-inch) wide 88 keys and with an auto-playing function weighs only 2.5-kilogram (5.5 lb).
3World’s Smallest Violin: just 1.6 inches (4.1 cm) long
The world’s smallest violin is not playing the world’s saddest song, but it could as it’s fully functional.In 1973, Eric Meissner succeeded in building the world’s smallest violin, which measured just 1.6 inches (4.1 cm) long
4World’s Smallest Harmonica: 1.9 inches (5 cm) long
With a dimension of 5 centimeters long by 1.5 centimeters wide, this harmonica is the smallest in the world. It is named “Little Lady” and is made in Germany in the late 1890s.
5World’s Smallest Harp: each string is only 150 atoms wide
The NanoHarp is a true stringed instrument that plays real music, if only we could hear it. It plays a tune too high for even a dog to hear.Its strings vibrate at frequencies as high as 380 MHz and are probably the fastest human-made moving object. The new device is carved out of a single crystal of silicon. The strings are actually silicon rods 50 nanometres (nm) in diameter, ranging from about 1,000 to 8,000nm long. A nanometre is one billionth of a meter, making each string about 150 atoms thick.The entire device is about the size of a red blood cell.
