well, no doubt i am impressed with what my clsmates did. majority of them can at least turn one side of the cube to the same color. everyone is learning it accept me. i know i cannot do it. really. once after 5 mins i cannot solve it, then i'll throw it away. i have no patient; u can't ask me to start and play with that small cube for a long time. some of my clsmates can turn all the six sides! so impressed that i took a picture of the cube. some even buy 6 by 6 to play! omgoodness.
