(PhysOrg.com) -- David Cox, a scientist in the Quantum Detection group at the National Physical Laboratory in the UK, is an expert in nanofabrication techniques. Recently, using the tools of his trade and a bit of humor, he has created his latest masterpiece: the world's smallest snowman, which measures just 0.01 mm across (about one-fifth the width of a human hair).

Cox created the snowman "by hand" using a system for manipulating nanoparticles. Rather than being made out of snow, the figure's head and body consist of two tiny beads that are normally used to calibrate lenses. Cox welded the beads together with a tiny bit of platinum, and then used a focused ion beam to carve the eyes and smile. Lastly, he used an ion beam to deposit a tiny blob of for the nose, which is less than one wide.

As shown in the video, the snowman is mounted on a silicon cantilever from an atomic force microscope, whose sharp tip is used to feel surfaces in order to create topographic surveys at very small scales.

While Cox's snowman holds the record for the smallest, MyFox News notes that the tallest snowman record is still held by the town of Bethel, Maine. Residents of the town built a snowman with a towering height of 113 feet, 7 inches, on February 17, 1999.

Wouldn't you rather have one made out of platinum though? :)

most of the snowmen in the world at any one time including winter are made from other materials,lol,true snowmen are a minority.

I"m with danman5000 make mine a very overweight one say 1000 lbs of pure platinum.

Red "Ring 0.01 mm diameter" which means the obviously wider head behind the ring must be about 0.0115 mm diameter. And the head is the least wide part! I estimate body width at approx. 0.0175 mm which, using less rough approximation than the author, is pushing 0.02 mm.

Also, I support fossilator's suspicion that a snowman should be made of snow. This is a beadman. No tiny snowman record here ... only more poor science reporting.

Imagine the poor dust mite that comes face to face with this snowman.
