The Master of the Cube

In 1981, the top selling book in America was a book that was called the simple solution to Rubik's cube. It sold 6 million copies and it was the number one book of the year. A speed demon has gone from 10 minutes to 40 seconds. An expert has gone from five minutes to 15 to 25 seconds. And the master of the cube, which is now called world champion from three minutes to three to five seconds. I can't even pick it up within three seconds. My old arthritic fingers.
