A noise-dampening ball for use in the game of pickleball is disclosed. The ball includes a novel layering arrangement which reduces noise generated during play without the need for a player to utilize an alternative paddle while falling within the size and weight standards established by the official body which oversees the sport. The ball demonstrates standard bounce characteristics while allowing the play to be undertaken without the level of noise currently experienced by pickleball players utilizing a conventional ball.

Disclosed are an exercise ball as well as a system, method and computer program product for monitoring the use of the exercise ball by a user. An exemplary system comprises: a first data processing unit; an exercise ball comprising a shell and a monitoring unit operatively associated with the shell, said monitoring unit comprising at least one sensor for detecting a parameter representative of the movement of the exercise ball by the user, the first data processing unit being configured to determine and provide the user with data representative of the use of the exercise ball by the user based on parameters representative of the movement of the exercise ball by the user detected by said at least one sensor.

The present disclosure relates to the technical field of water playing toys, particularly to a toy water balloon, which comprises a flexible shell, a flexible cover and an elastic arm. The flexible shell limits a water storage cavity and an opening connects the water storage cavity and the external space of the flexible shell. The outer contour of the flexible cover is larger than that of the opening to seal the water storage cavity. It is only needed to make the toy water balloon deformation by using the opening to expose the water storage cavity. Which results in higher safety and lower production cost. Compared with the non-magnetic toy water balloon, the flexible cover will stick closely to the inner wall of the water storage cavity so that the toy water balloon disclosed in the present application has good sealing properties.

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.
