Found an interesting article describing how to solve the Rubik’s cube blindfolded. Yes, you read it right. The prerequisite for solving the puzzle is determination. People have reported to have learned and mastered the method having never solved a cube with his eyes open.
It’s cool!! check it out for yourself.
