Rubik's Cube

What is it with solving Rubik's cubes and Hung kye? Anybody can solve one but students are asking him and ONLY him to solve it. His "toughest" one yet was a 3*3 cube but can solve in the blink of an eye.Even I asked him to solve mine and manged to solve it. I guess he gets the pleasure and thinks it's So easy to solve one! I think not!:)
