Teen solves Cube in under 5 seconds NOV 25 2015
Fourteen-year-old Lucas Etter solved a randomly scrambled Rubik's Cube in just 4.9 seconds the other day, the first time anyone has ever solved one under five seconds. As Oliver Roeder writes over at 538, Cube solve times have fallen quickly in the past decade.
In these competitions, the colorful cubes are randomly scrambled according to a computer program, and a solver has 15 seconds to inspect a cube before racing to spin it back to its organized state. The first official record - 22.95 seconds - was set at the first world championship, held in 1982 in Hungary, home country of the cube's inventor, Erno Rubik. But speed cubing went into hibernation for two decades, until the next world championship was held in 2003. From there, the record has fallen precipitously, thanks to innovations like the Fridrich method, the Petrus system and even "cube lube."
