“A Boy and His Atom” holds the distinction of being the world’s smallest stop-motion film according to the Guinness Book of World Records. Created by IBM, the film showcases individual atoms moving to create a simple and whimsical narrative. IBM researchers used a scanning tunneling microscope to move thousands of carbon monoxide molecules (two atoms stacked on top of each other), all in pursuit of making a movie so small it can be seen only when you magnify it 100 million times. Below, you can see the behind-the-scenes process how “A Boy and His Atom” was made.
