A toy wall ball includes a pair of petals and a connecting portion connecting the petals. Each petal includes a body, a frame extending inward from the body and a magnetic attraction assembly embedded between the body and the frame. Each magnetic attraction assembly includes magnetic members and a fixing member including fixing cases and connecting strips. Each fixing case encloses a corresponding magnetic member and is connected to a connecting strip. When the petals are in a closed state, the petals jointly enclose and define a water-carrying cavity, and the magnetic members of the petals attract each other to have the frames of the petals tightly contact each other to form a water retaining layer that seals the water-carrying cavity. The connection area between the magnetic members and the frame and body is increased, thereby greatly reducing the risk of the magnetic members falling off the petals and improving safety.

A toy water ball includes a plurality of petals each having a first edge portion and a second edge portion. Each first edge portion is provided with first magnetic members, and each second edge portion is provided with second magnetic members. When all petals are closed to form a spherical shape, an attraction force is generated between the first magnetic members of each petal and the second magnetic members of the adjacent petal so that the first edge portion of the petal tightly fit the second edge portion of the adjacent petal and a water-carrying cavity is formed. The toy water ball can be closed or opened repeatedly and can be reused. Thus, it is environmentally friendly and clean. Furthermore, the toy water ball can be filled with water in a common water source without a specific pressure, so it can be used in many occasions, and has strong applicability.

A pickleball training paddle and method may include a paddle having a playing surface with a reduced area and a training ball made from a rubber-like material.

Synergistic pairing of golf clubs with golf balls both with improved aerodynamic properties to help improve the performance of both. In an example, a golf club has a golf club head; a grip; and a shaft having a tip end and a butt end. The golf club head is coupled to the shaft at the tip end, and the grip is coupled to the shaft at the butt end. The golf ball has at least a core and a cover having a plurality of dimples arranged in a dimple pattern.

The present application relates to a toy comprising an internal ball structure comprising a highly resilient material capable of significant bouncing off a hard surface, a plush fabric skin configured to cover the internal ball structure such that the plush fabric exterior does not significantly impact or dampen the ability of the internal bouncing ball structure to bounce when impacting a surface.

Various aspects of a dimple pattern methodology, and dimple pattern configurations are disclosed herein. A spherical triangle segment division can be used to maintain a high level of symmetry in the dimple pattern while also maintaining a specific dimple layout in polar regions of the golf ball. In one aspect, the specific configurations disclosed herein can provide geometric symmetry while being adaptable to relatively complex processes for forming golf ball covers. Furthermore, the configurations disclosed herein provide a dimple pattern with a high level of symmetry having a particular subset of preferred polar dimples.

A ball is configured for use in racket and paddle sport games. These configurations include a material composition that is sensitive to mechanical force. This composition may change colors in response to a crack or other defect in the surface of the ball. In one implementation, the ball may have a thin, peripheral wall that encloses a hollow interior. This ball may find use in pickleball and, thus, meets the requirements and parameters for use in the sport.
