In 2009 we had Nano-teddy, this year it's Nano Snowman!
David Cox from the National Physical Laboratory in the UK has built the world's smallest snowman - perhaps because he was trapped inside by the winter blizzards with nothing much else to do...
The snowman is 10 µm across, which is roughly 1/5th the width of a human hair. Its head and body are made from two tin beads. The eyes and smile were carved from the tin with a focused ion beam, and the nose, which is less than 1 µm across, is a deposited blob of platinum.
Hope all our UK and European readers are enjoying the snow!
