The rotation resulting from this torque is not downward, as might be intuitively expected, causing the device to fall, but perpendicular to both the gravitational torque ( horizontal and perpendicular to the axis of rotation ) and the axis of rotation ( horizontal and outwards from the point of support ), i. e., about a vertical axis, causing the device to rotate slowly about the supporting point.

rotation and torque
An alternative explanation is that the moving arms have precession torque on them which set the body into twisting rotation.
Moving the arms back produces opposite torque which stops the twisting rotation.

The gravitational torque between the Moon and the tidal bulge of the Earth causes the Moon to be promoted in its orbit, and the Earth to be decelerated in its rotation.
It follows from this that a torque τ applied perpendicular to the axis of rotation, and therefore perpendicular to L, results in a rotation about an axis perpendicular to both τ and L. This motion is called precession.
