Rubik

Cube of Rubik
Lately, I play with this thing. Rubik's 3x3.
It's interesting like a mysterious cube.
Until now. The fastest I can get was 1 minute and 30 seconds with open eyes.
And The fastest in the world that I knew was 4 seconds with eyes closed.
I was wondering, how can he be that fast.?
And he was doing it with eyes closed.
What a shocking rubik's person we got here?
How can he do that?
It's still a mystery for me.
