Abstract
A sealed container with a movable weight therein is eccentrically mounted within a light rollable object on a guideway. Liquid mercury, powered metal, or metal pellets or spheres would move within the container to shift the center of gravity. Maintaining the center of gravity of the weight to the uphill side of a vertical extension of the tangent between the rolling object and the guideway will enable the rolling object to return uphill after rolling down within a limit, thereby seeming to defy the law of gravity.
