An inflatable or inflated ball comprising an outer chamber formed of an airtight flexible outer skin which, when properly inflated and fully expanded, defines an interior volume. A sealed inner chamber filled or fillable with a substance substantially heavier than air is positioned within and occupies a relatively small amount of the interior volume. A plurality of elongated radially extending and three-dimensionally spaced elastic members are each connected and radially extend between, the inner chamber and the inner surface of the outer chamber. The elastic members are cooperatively sized in length and suitably tensioned to support and hold the inner chamber centrally in an at-rest position within the interior volume. Each of the elastic members will cooperatively stretch and contact in response to ball movement, such as rolling or being thrown and impact of the ball against a surface, causing the inner chamber to be unpredictably displaced from the at-rest position by gravity and inertia resulting in erratic movement of the ball. A hand grip molded with and radially extending from the outer skin is also provided for enhanced sitting and bouncing play action.
