The Rubik's Cube is a puzzle toy invented by Erno Rubik in 1974. It consists of a cube with a turnable 3x3 grid on each side. The goal is to align every side with each color on the cube and can be achieved by using a complex algorithm pattern. There is a world record for fastest time to complete one.
The Rubik's Cube appears twice in Gravity. The first one in the Explorer cockpit. The second one at the International Space Station .
