A researcher at Western University's Nanofabrication Facility in Ontario, Canada, has built the world's smallest snowman, measuring an extremely petite 3 microns tall. To put this in perspective, a human hair will typically be 50-75 microns (or micrometers) thick.
The tiny snowman was made using a stack of silica spheres -- water crystals would be far too large for a sculpture of this stature. Each of the three globes is a mere 0.9 microns (0.0009 millimeters) in diameter. The arms and carrot-like nose are made from platinum, and the facial features were carved using the lab's new focused ion beam.
