If I practice with Rubik's Cube for many many hours ?

Question

and ultimately learn how to solve the cube in less than twenty seconds, will women be impressed and want to date me?

Answer 1

you dont have to get to sub-20 to impress people. i can do it in 14 and blind them with the quickly switching colours, but people are more impressed if you do it slower.

doing it fast makes them think "wow this guy must practice for hours"

doing it slower, no finger tricks, just average human speed turning, will make them think "holy %^$#, that guy is smart!!!!!!!"  

Answer 2

If that is all it takes to impress a lady, would you really want to date her?  Oh, well, maybe so.  Good luck.  :=)

Answer 3

I would be impressed but most of the time I've seen guys do that but still not be looked at as good and cute enough to date. so i'd say try something else unless you already know how to and wish togive a demonstation of even more skills than just a rubik's cube
