Scientists Create World's Smallest Snowman—He's Just 0.00012 Inches Tall
Created by the Western University Nanofabrication Facility in London, Ontario, this tiny snowman stands just under 3 microns tall. One micron is one millionth of a meter, or approximately 0.00004 inches, so yeah, it's super duper small: 0.00012 inches tall to be exact.
He may be small but he's also super duper adorable.
Sadly, he's not actually made of snow. According to the original Tumblr post:
The World's Smallest Snowman stands less than 3 microns tall. The snowman was fabricated from three 0.9 micron silica spheres stacked with the use of electron beam lithography. The eyes and mouth were cut with a focused ion beam while the arms and nose were sculpted with platinum.
For reference, the average human red blood cell (the smallest human cell) is approximately 5 microns in diameter, so the snowman is even smaller than a single human blood cell. On top of that, the naked human eye can only see objects as small as 0.1 mm (100x larger than a micron), so you need a pretty strong microscope to even be able to peep our little snowman friend. These images were taken with an scanning electron microscope:
Western University's small snowman took the world record from the National Physical Laboratory in London, the previous record holder for their snowman who came in at about 0.01 millimeters, or 10 micrometers. The new record is less than half the size, which is pretty remarkable given the scale on which these labs are working.
You all know how I feel about projects conducted on a miniature level, and this is no exception. Visions of microscopic men of snow will be dancing in my head this holiday weekend and I don't hate it. Happy holidays, everyone!
