The World’s Smallest Snowman

Scientists at the National Physical Laboratory in West London have built the world’s smallest snowman which measures just 0.01 mm across (1/5th the width of a human hair.) but it is not made of snow. It is made up of two tiny tin beads used to calibrate electron microscope lenses which were welded together with platinum.

A sharp and focused ion beam was used to cut and shape the snowman’s eyes and smile and used a tiny blob of platinum for the nose.

Dr.David Cox, a member of the Quantum Detection group at the laboratory and he is accustomed to working with such astonishingly small objects by using his nano-particle manipulation tools. He created the snowman “by hand” using a system for manipulating nanoparticles
