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.

A repeatable use valve in a tennis ball that uses a common sports ball inflation needle inserted into and through the valve to increase or decrease the pressure inside the ball. The increase or decrease in pressure will cause the ball to have respectively higher or lower bounce. The valve can be installed in new tennis balls at the time of manufacture. The valve can also be installed in used tennis balls, including used tennis balls that have lost some or all of their original factory pressure.

A balloon valve and pouch assembly 1 is mounted in a neck portion of a balloon and comprises a balloon valve 2 and a pouch 3. The pouch 3 is adapted to receive and retain an illumination device 100 in a predetermined position. The valve 2 has a valve inlet 2A and a valve outlet 2B provided at an opposite end of the valve 2. The valve 2 is delimited by sealing path 4 and layers 2C, 2D. The pouch 3 comprises an opening 3A through which an illumination device 100 can be inserted and a closed opposite end of the pouch 3B. The pouch 3 is delimited by the first sealing path 5 and layers 3C, 3D. The layers 3C, 3D are heat-sealed together along a first sealing path 5, which is substantially V-shaped, with the open end of the V-shape defining the pouch opening 3A and the closed end of the V-shape defining the closed end of the pouch 3B.

A chair facilitates both rocking and bouncing. The chair includes a base adapted to support a seating portion, the seating portion having a surface adapted to be sat on by a user. The seating portion has a bouncing mechanism, such as an exercise ball. A rocking mechanism is provided to cause the base to rock. The rocking mechanism facilitates the rocking back and forth of the user when the user is seated on the seating portion, and the bouncing mechanism facilitates the bouncing of the user when the user is seated on the seating portion. The bouncing is in a bouncing direction that is different than the direction of rocking. The chair is particularly useful for calming a baby and/or for facilitating stimming.

Systems, apparatus, and methods related to recreational balls with illuminated surfaces are described herein. In some embodiments, an apparatus includes an air-tight object having an outer layer and an inner layer. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines an aperture. Additionally, a light module is configured to send light from an interior of the air-tight object through the aperture of the outer layer.
