IBM scientists used carbon atoms as stars in their film 'A Boy and his Atom' which is being called the world's smallest movie.
Researchers moved the tiny particles around on a copper plate using a special kind of microscope.
They then took photographs of them arranged in different pictures which were edited into the short film.
It would take about 1,000 of the frames of the film laid side by side to be the width of a single human hair.
