At just 10 µm across, this little guy is only 1/5th the width of a human hair. The snowman was made from two tin beads used to calibrate electron microscope astigmatism. The eyes and smile were milled using a focused ion beam, and the nose, which is under 1 µm wide (or 0.001 mm), is ion beam deposited platinum. Image and video via the UK’s National Physical Laboratory.
