Marcell Endrey set a world record recently by solving a Rubik’s Cube blindfolded in 28.80 seconds. Marcell starts by looking at the cube for 10 seconds and solves it in the remaining 18 seconds blindfolded. There is no way we could complete a Rubik’s cube in 28 seconds let alone know where to begin. Check out David Calvo’s attempt at solving and juggling Rubik’s Cubes.
