Gyroscopic Forces: Designing a Spinning-Top Object

[gibxam]

Gyroscopic Forces??

Is it possible to create an object that is basically a spinning top but because of the way it is made will spin forever? If not what would be the best design for a 'spinning-top like' object? I think I need to do some research on Gyroscopic Forces but I'd like to be pointed in the right direction. Thank you.

A normal spinning top will spin forever, at least in theory. However in reality there is friction, which will slow down the top over time. This will be the case with any contraption that you can come up with.
