Well, there is gravity up at the Space Station. It's only down a few 
percent from surface gravity. But the station is in free-fall. So 
gravity becomes non-apparent, just like if you were in a freely falling 
elevator on the surface of the earth, or an airplane in free fall.

In no gravity, no, a top never falls over because there's no "down". 
More importantly, it never PRECESSES. Because there is no external 
gravity to provide the torque.
