sixpenceee: World’s Smallest SnowmanIn 2009, scientists created the world’s smallest “snowman,” measuring about a fifth of the width of a human hair. Experts at the National Physical Laboratory in West London made the miniature figure which is just 0.01mm across. It was assembled using tools designed for manipulating nanoparticles.The snowman is made of two tiny tin beads, normally used to calibrate electron microscope lenses, which were welded together with platinum. A focused ion beam was used to carve the snowman’s eyes and smile, and to deposit a tiny blob of platinum for the nose. It was put together by Dr David Cox, a member of the Quantum Detection group at the laboratory, who also took the picture. (Source) -- source link
