My chemistry teacher from last semester showed me and a couple of other kids from our class this today. I found it really cool and HAD to share it here lol.

World's Tiniest Movie Uses Atoms As Actors

Scientists at IBM Research have just earned a Guinness world record for the smallest movie ever: They created a stop-motion film by moving atoms, one at a time, across a copper surface. The result is the sweet story of a boy named Atom, who befriends a single atom and then goes dancing, plays catch and jumps on a trampoline.

To make the 242-frame film, principle investigator Andreas Heinrich and his team used a two-ton scanning tunneling microscope, cooled to -450 degrees Fahreinheit, to magnify the atoms more than 100 million times.
The scanning tunneling microscope isn't an optical microscope. A robot arm moves a tiny needle (its tip is a single atom) across the copper surface in a scanning pattern, "like an old-fashioned TV tube," Heinrich explains. The needle is programmed to stay a certain distance away from the surface, so when it encounters an atom, it pulls up and creates a bump in the image. To move an atom, the researchers lower the needle to push or pull it to a new position on the copper surface.

Each of the ball-bearing-like dots in the movie is actually made of two atoms, which form single carbon monoxide molecules. The ripples that appear around them are a result of free-floating electrons trapped in the ultra-smooth copper surface. "If you disturb the 2-D electron gas surface by moving atoms on it, you see ripples," Heinrich says. "These electrons are free, like atoms in a gas, except they are stuck on the surface."
It took four scientists working in shifts over 10 18-hour days to create "A Boy and His Atom." In the end, they moved about 10,000 atoms with the scanning tunneling microscope. The character Atom is made of about 120-130 atoms.

Last year, the same group of IBM researchers used the scanning tunneling microscope to create the world's smallest memory bit, which stores data using only 12 atoms.
