I was in second grade when Rubik's cube became a craze. I never mastered it but it became one of the most unforgettable toys that ever came out. It was simple yet complex. Rubik's cube is certainly one of the most clever inventions of the 20th century. Now, in the 21st century, a new Rubik's Cube was launched, this is dubbed as the "first completely electronic, solvable Rubik's Cube." Intrigued? Watch the video to see what I am talking about. Well, it's not yet in stores but soon it will be available.
