World's Smallest, Nano Scale Snowman
The snowman measures 10 m across and is 1/5th the width of a human hair.
The National Physical Laboratory (NPL) is one of the UK's leading science and research facilities. This Christmas, they used an atomic force microscope to craft the World's smallest snowman. The snowman measures 10 µm across and is 1/5th the width of a human hair.
