DESCRIPTION
This gyroscope is supported at its center of mass, so it experiences no gravitational torque and can spin stably in any orientation.

If you bring the extended shaft of the gyroscope in contact with the wire spiral, or a pencil or whatever, the torque due to the frictional force increases the normal force between the shaft and the wire, and the gyroscope rolls along the contours of the wire.
