Der kleinste Schneemann der Welt…

The snowman is 10 µm across, 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.
