There is an unseen world, filled with tiny things which resides in our own. It just got a little more festive. Scientists at the National Physical Laboratory have built the world’s smallest snowman. And they didn’t create it using balls of snow.
Instead they used two tiny beads. Beads typically used by physicists to calibrate electron microscope lenses. The pieces were welded together with platinum. It measures just 0.01mm (1/5 the width of human hair). It’s the result of manipulation of nanotech particles.
