A launching and/or catching toy kit has a football and at least one associated slingshot. The football includes a generally elongated spheroidal body, a support non-movably attached to the body, a tail, a first and a second elastic band hook oppositely disposed, and a lift-generating wing. The slingshot is configured to launch the football from a first user to a second user. The slingshot includes a handle and a pair of prongs connected and/or extending from the handle top. At least one elastic band is connected to each prong. Each of the at least one elastic bands are releasably captured by their respective first or second elastic band hook on the football during launching by the first user. When two slingshots are available, the users can shoot and catch the football between each other allowing for a game of catch.

A sports ball includes sensing electronics embedded therein. The electronics are supported on an inner surface of the wall of the ball within an elastomeric boot that extends inwardly toward the center of the ball. The elastomeric boot is configured to protect the electronics from damage due to shock as the ball is used, and to have little if any effect on the performance characteristics of the ball.

A method and a bowling ball enclosure are provided for encasing and reducing temperature fluctuations of and within a bowling ball. The bowling ball enclosure includes a flexible inner vapor barrier layer and a flexible outer layer that are made of a polymer material, the inner layer forming an interior region that receives the bowling ball. The bowling ball enclosure also includes a bottom portion and a top portion, wherein the top portion is positionable from a first position to a second position to encapsulate the bowling ball. In the first position, the top portion being in an open position to receive the bowling ball into the interior region. In the second position, the top portion being in a closed position to encapsulate the bowling bowl. A thermal resistor can be located between the bowling ball enclosure and a support surface.

A mouthguard carry case (10) comprising: an outer shell (12) having a hollow interior defined by an open top, an open bottom and a plurality of side walls (14). The mouthguard carry case (10) also comprises an inner shell (18) having a hollow interior defined by a top wall (20), a bottom wall (22) and plurality of side walls (24). The inner shell (18) is slidably received within the hollow interior of the outer shell (12) and is movable between an open position, and a closed position. Advantageously the mouthguard carry case (10) can be opened and closed in one hand, and is fully ventilated to promote drying and inhibit the growth of oral bacteria.

An aerodynamic golf club head having body attributes that impart beneficial aerodynamic properties.

A method of controlling a gyroscopically-stabilized projectile, comprising a control system producing a control signal, a rotating aerodynamic shell, and a reaction mass system responsive to the control signal, the method comprising: imparting rotational and translational kinetic energy to induce gyroscopic stabilization of the projectile about a gyroscopic axis and a movement of the projectile along a flight path; interacting the shell with surrounding air while moving, to induce aerodynamic forces; generating the control signal from the control system; and altering a state of the reaction wheel system selectively in dependence on the control signal, to alter the flight path.

Disclosed herein are various embodiments of a golf club head having improved mass distribution characteristics. The golf club head includes a body and a face positioned at a forward portion of the body. The golf club head also includes one or more mass elements positioned at predetermined locations about the head. The mass elements assist in achieving a desired relationship between the moment of inertia about a center of gravity x-axis and the moment of inertia about a center of gravity z-axis.

An aerodynamic golf club head producing reduced aerodynamic drag forces via unique club head relationships.
