Abstract: Non-standard sport projectiles, in accordance with this invention, include at least one linear through hole. As this non-standard sport projectile passes through the air, after being hit by, for example, a golf club, the non-standard sport projectile spins. When the above-mentioned through hole is generally aligned with the projectile's direction of flight, air passes through the through hole, and the aerodynamic characteristics of the non-standard sport projectile are enhanced. When the through hole is not aligned with the projectiles direction of flight the aerodynamic characteristics are reduced. As a result, the non-standard sport projectile experiences rapidly repeating intervals of relatively high aerodynamic flight and relatively low aerodynamic flight as the non-standard sport projectile spins around the center cross section of the through hole.

Abstract: A ball toy 10 intended for use by pets that is molded of a flexible, resilient material, containing a hollow cavity inside 22. Attached to the hollow cavity is a squeaker 20. The squeaker 20 is activated by air rushing through it, into and out of the hollow cavity within the ball, as the ball 10 is squeezed and released. The ball. 10 is essentially round, allowing it to roll freely and easily in any direction. The ball 10 has features molded in relief on its outer surface 12 which resemble the face 14, legs 16, and tail 18 of an animal. The protruding features 14, 16, 18 cause the ball 10 to roll in a slightly erratic manner and may cause a light pitter-patter sound when the ball 10 rolled on a smooth surface, thus creating a resemblance to a small scurrying animal.

Abstract: The invention pertains to a sports training ball designed to develop reaction and reflex skills, while keeping interest and enthusiasm high among the participants due to the unpredictable bounces the seven-knob rubber ball creates. It is well suited for training in many sports including baseball and is effective to help young athletes develop their visual tracking skills, reaction skills, and catching skills. Its unique seven-knob design ensures a different bounce every time it bounces against a flat surface. The seven-knob design includes two identical knobs of a larger size and five identical knobs of a smaller size and the ball is approximately the same mass as a tennis ball and a baseball. In short, it is challenging, but allows children of varying ages and skill levels to achieve success while building their skills.

Abstract: The invention is of a ball game device and method of using the same comprising a octahedron body made of a resilient material preferably durable rubber foam like material, plastic, or rubber and dimensioned to be kicked, rolled, or thrown on a 360 degree, flat, playing surface either indoors or outdoors.
