In 1974 Hungarian architect and professor Erno Rubik wanted to create a tangible object to teach his students about spacial relationships. This resulted in a model made using chunks of wood and rubber bands to form a structure that allowed individual blocks to move independently of one another without the entire structure falling apart. He called it the Magic Cube (buvös kockain Hungarian). Rubik said, “It was a piece of art but at the same time it was an intellectual task as well.” It took Rubik over a month to solve the puzzle himself. “It was code I myself invented! Yet I could not read it.” At the time Hungary was behind the Iron Curtain, so it took a bit longer to market Rubik’s puzzle to the rest of the world. It was shown in a new plastic form at the Nuremberg Toy Fair in 1979, where famous toys such as the Playmobil line launched in 1974. BY 1980 the Rubik’s cube (its name now officially changed from the Magic Cube) was licensed by the ideal Toy Company. This cube is made up of 27 plastic pieces (cutlets, as they are often called)., but only 26 are visible to the eye (there is one in the very center of the cube). Each side of the overall cube measures 2.25 inches; each cube let has a concealed inward extension that interlocks with other while permitting them to move to different locations.
