World's smallest snowman

[VectraMan]

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.

A nanomanipulation system was used to assemble the parts 'by hand' and platinum deposition was used to weld all elements together. The snowman is mounted on a silicon cantilever from an atomic force microscope whose sharp tip 'feels' surfaces creating topographic surveys at almost atomic scales.

And they didn't even need a consensus.

I've already sent this link to the BBC to complain that a national institution are behaving in an outragously sexist manner by using the term Snowman when they should have called it a Snowperson

Stop trying to confuse the issue with science!

I've made the world's smallest icecream out of an atom of hydrogen.

Because "Worlds smallest little fat f**ker" may have offended some...
