NPL Snowman by NPL
Scientists also know how to have fun and no less than the others are waiting for the onset of Christmas and New Year holidays. Only now, as it turned out, they even “mold” a snowman completely =)
It's simple - using their own scientific tools, scientists at the British National Physical Laboratory (National Physics Laboratory, NPL) - created the world's smallest snowman.
Of course, the name is somewhat conditional, since no snow is suitable for such creativity. The diameter of a microscopic object is just over 10 microns (0.01 mm), or one fifth of the thickness of a human hair. According to the NPL explanation, the "snowman" was made from two microscopic beads, commonly used to calibrate the astigmatism of an electron microscope. The eyes and smile came out through the use of a focused ion beam, and the nose with a diameter of 0.001 mm is platinum deposited by a beam.

All elements were formed by hand through a nanomanipulation system, and scientists connected them together using platinum deposition techniques. The figure is located on a silicon cantilever of an atomic force microscope. The cantilever is a construction from a miniature platform and a tip, with the help of which a microscope “scans” the surface of the sample under study. Unfortunately, the NPL technology does not allow making a carrot.
