World's smallest snowman

This adorable snowman is only a wee 10 µm across or for comparison only 1/5th the width of a human hair and was created by brainiacs at National Physical Laboratory. For more background information watch this behind-the-scenes YouTube video that explains that “a nanomanipulation system was used to assemble the parts ‘by hand’ and platinum deposition was used to weld all elements together. The snowman is mounted on a silicon cantilever from an atomic force microscope whose sharp tip ‘feels’ surfaces creating topographic surveys at almost atomic scales.” Got that? These scientists stole my thunder because I was totally going to make one this weekend.
