A beer pong tabletop game is an apparatus that connects ping pong balls to a tabletop during a game while maintaining the freedom of movement for the ping pong balls, and consequently the players. The apparatus includes at least one anchoring disk, a first elastic string, a second elastic string, a first ping pong ball, second ping pong ball, and a pull tab. The at least one anchoring disk is secured with the tabletop. The first elastic string and the second elastic string attaches the first ping pong ball and the second ping pong ball with the at least one anchoring disk, respectively. The first ping pong ball and the second ping pong ball are shot into cups positioned across the tabletop. The pull tab facilitates an even length adjustment of the first elastic string and the second elastic string with the at least one anchoring disk.

A method can include providing an object having a size smaller than a size of a known regulation object, projecting the object, via a delivery device, toward a trainee, and training the trainee to follow the object. A method can include determining a game parameter of a game trajectory of a sports object that was projected along the game trajectory in a real-time sports event, and based on the game parameters, adapting a delivery device to deliver a training object along a training trajectory that mimics at least a portion of the game trajectory, with the training object being smaller than the sports object.

A ball includes a first housing, at least six light emitting structures, a woven structure, and a second housing. The light emitting structures are symmetrically disposed on the first housing. Each light emitting structure includes a fixing unit, a light emitting unit, and a first light permeable unit. The fixing unit is disposed on the first housing. The light emitting unit is located between the fixing unit and the first light permeable unit. The woven structure includes a plurality of woven units, which are at least partially overlapped and covering the first housing. The second housing covers the woven structure and includes a first material layer, a second material layer, and at least six second light permeable units. The first material layer covers the second material layer. The second light permeable units are disposed on the second material layer corresponding to the positions of the light emitting structures.

Golf balls having multi-layered covers, wherein at least one of the cover layers is substantially transparent, are provided. The cover includes an inner cover layer made of an ionomer composition; an intermediate cover layer made of an aromatic polyurethane composition; and outer cover layer made of an aliphatic polyurethane composition, wherein the total thickness of the multi-layered cover is no greater than 0.110 inches. In one version, the outer cover layer is substantially transparent and the underlying intermediate cover layer is colored. In another version, both the outer and intermediate cover layers are substantially transparent. Light-reflective fillers such as pearlescent pigments, glitter, and metallics may be added to the cover layers. The resulting ball has pleasing decorative effects.

An inflatable solar-powered light is provided. The solar-powered light includes a bladder and a solar-powered light assembly disposed entirely within the bladder. The solar-powered light assembly includes a solar panel, a rechargeable battery in electrical communication with the solar panel, and at least one light-emitting diode in electrical communication with the rechargeable battery. The bladder is substantially transparent, flexible, inflatable, and collapsible.
