Man tries to make world's largest Rubik's Cube
British puzzle designer Tony Fisher has attempted to make the world's largest fully functional 3x3x3 Rubik's Cube, hoping to make it to the Guinness Book of World Records. The 1.56 metre-high cube weighs around 100 kg and its volume is around 20,000 times a normal Rubik's Cube. A person needs to walk around the cube to move its coloured squares.
