Thread: What's the name of this unusual Gizmo?

In February I saw a Scientifically designed object on TV. The object was round in shape and I think it was made of glass. The interesting thing about this object was that it's designed so that it's impossible to stop it from moving. If you put it on a flat table the object rolled away. You can't get it to stay still on any smooth surface.......

Sorry, but it's been bugging me for ages to find out what this thing was actually called and where you get one.

Anyone know what the hell I'm talking about?

the term "Scientifically designed object" makes one work pop into my mind: hoax.

sounds like the sphere has a weight buried inside so it's center of gravity is not where you think it is. You have to set it down with that heavy part down.
