Abstract
Abstract A game footbag designed to be kicked repeatedly into the air discloses a durable, flexible cover having a generally spherical shape when fully expanded and partially filled with material having substantially fluid characteristics. The cover consists of two dogbone-shaped pieces of flexible material attached together at their peripheries so as to form a collapsible ball. The fluid material includes a large plurality of small polythylene particles having low resilience. The interaction of the cover with the fluid-like material results in a footbag having a slow-action and uniform response to kicking.
