The World’s Smallest Snowman

The National Physical Laboratory has been around since the early 1900s and is famous for a number of its creations, such as the first working atomic clock. But never let it be said that it's all work and no play in the lab. Just in time for Christmas, the NPL, located in Middlesex, England, has created the world's smallest snowman. The snowman is not visible to the naked eye, being only one-fifth the width of a human hair. It was created with two tin beads used to calibrate electron microscope astigmatism. The nose is ion beam deposited platinum and the rest of the face was milled using a focused ion beam. All that scientific mumbo-jumbo aside, this tiny snowman is adorable!
