The Rubik's cube

Here comes the Rubik's cube fanaticism again. I can see many of my juniors holding or playing with the cube in my previous school ( although toys are inhibited in school ) . Well I had almost stopped playing it since last year because it would be boring once you had understood the way to solve it and couldn't beat your fastest record after solving it repeatedly for about hundreds time in using the same method. However learning it is fun and challenging as it is not as hard as what people expect.

The video above is my fastest record after addicted to it for three months :)
