What you're watching above isn't your ordinary film. No this film -- A Boy And His Atom -- holds the Guinness World Record for being the World's Smallest Stop-Motion Film. It's literally a movie made with atoms, created by IBM nanophysicists who have "used a scanning tunneling microscope to move thousands of carbon monoxide molecules, all in the pursuit of making a movie so small it can be seen only when you magnify it 100 million times." If you're wondering what that means exactly, then I'd encourage you to watch the behind-the-scenes documentary below. It takes you right onto the set -- or, rather into the laboratories -- where IBM scientists reveal how they move 5,000 molecules around, creating a story frame by frame. As you watch the documentary, you'll realize how far nanotechnology has come since Richard Feynman laid the conceptual foundations for the field in 1959.
