I never understood why they gave ten year olds a Rubik's Cube. It's probably the best selling toy in the world but it always made me feel stupid, let alone angry, cause I couldn't get it right. Ever. I learned that it has 43,252,003,274,489,856,000 possible configurations. That's 43 quintillion. Right! There are people who speedcube. They try to solve the puzzle really, really FAST! Mats Valk from the Netherlands holds the speedcubing record for a 3x3x3 Rubik's cube. He needed 5,55 seconds to solve it. Watch this!
