Physicists use their nano-skills for the greater good, by creating a tiny bit of holiday cheer
Tiniest Snowman: Hey guys, I'm ... OH MY GOD WHAT AM I MADE OF?? National Physics Laboratory
What do tiny smiling snowmen mean for science? Not much; these physicists just decided to show off their ability to make really small things.
This little guy measures just 10 micrometers across, or just 1/5th the width of a human hair. Scientists at the National Physics Laboratory in the UK built the snowman body from two tin beads, and milled the eyes and smile in the top bead using a focused ion beam. The snowman also has a platinum nose deposited by said ion beam, which probably beats a silly carrot any day.
