　　Named "A Boy and His Atom," the movie used thousands of precisely¹ placed atoms to create nearly 250 frames of stop-motion action. It depicts² a character named Atom who befriends a single atom and goes on a playful journey that includes dancing, playing catch and bouncing on a trampoline.

　　"Capturing, positioning and shaping atoms to create an original motion picture on the atomic-level is a precise science and entirely³ novel," said Andreas Heinrich, principle investigator⁴ for the research in a statement.

　　"This movie is a fun way to share the atomic-scale world while opening up a dialogue with students and others on the new frontiers of math and science," Heinrich said.

　　IBM used a remotely operated scanning tunneling microscope to make the movie earlier this year. The microscope operates at a temperature of negative 268 degrees Celsius⁵ and magnifies the atomic surface over 100 million times.

　　Researchers used the microscope to control a super-sharp needle along a copper⁶ surface to "feel" atoms. Only 1 nanometer away from the surface, which is a billionth of a meter in distance, the needle can physically⁷ attract atoms and molecules⁸ on the surface and thus pull them to a precisely specified⁹ location on the surface.

　　In the end, the scientists rendered still images of the individually arranged atoms, resulting in 242 single frames.
