Abstract
A wobbling toy is configured to spontaneously re-orient itself in an upright position solely under the force of gravity. The self-righting toy includes a weight that is confined to and movable along a pathway such that the weight defines a dynamic mass that is sufficient to cause the housing to spontaneously pivot along a convex outer surface profile in coordination with a position of the weight in the pathway. The self-righting toy is configured to maintain a positional relationship of the weight so that the housing is spontaneously pivotable along the convex surface without external force supplied by a user.
