A swimming training aid is provided and comprises an elongate buoyant body. The body has a generally circular section along substantially the entirety of its length, and the diameter of the body is non-constant along at least the majority of its length.

A toy water ball includes at least two shells that are enclosable to form a water storage cavity, each of the shells including: a mounting frame, a magnetic member and a water pocket mounted on the mounting frame. The mounting frame includes a first surface and a second surface oppositely arranged in a thickness direction thereof. When the shells are enclosed to form the water storage cavity, magnetic members of adjacent shells attract each other, and second surfaces of adjacent shells abut each other. The mounting frame is provided with an accommodation groove, a notch of the accommodation groove is located on the first surface, the magnetic member is installed in the accommodation groove, and the water pocket is connected to the first surface, and covers the notch of the accommodation groove on the first surface to seal the magnetic member in the mounting frame.

An underwater retrieval game system employs a submersible target having a combination of features that make it difficult to locate underwater. The body portion of the submersible target is translucent and has a density greater than water. The target may be tossed in a swimming pool and sink to the bottom. A game player may jump into the water and try to locate the target. A combination of additional features such as size, shape, and surface texture may make it more difficult to spot the target underwater. A submersible target may comprise a detection device, such as a small light, that is activated after a certain period of time or is activated remotely by a wireless signal. A game player may be challenged to find the targets before the detection device is activated, for example.

Embodiments of the present disclosure relate to water effect play structures for use in playgrounds, splash pads, and water parks. The play structures comprise a plurality of water tanks maintained at an elevation above a play surface. Each of the plurality of water tanks fills with water and then releases the water contained therein, splashing children in the vicinity. Each of the plurality of water tanks may be configured to release the water contained therein at different times. Further, in some embodiments, the water tanks may be enclosed, such as by being connected to a water transport system that fills the tanks internally and by having a movable cover over the opening(s) through which the water is released.

The present disclosure discloses a squeeze type stress relieving toy with a water storage function, including an outer bottle body; a bottle cover which is detachably connected to the outer bottle body; a fixed cover which is fixedly arranged on the outer bottle body and is wrapped by the bottle cover; an isolation structure which is arranged in the outer bottle body and disposed below the fixed cover; a paste discharge simulation structure which movably penetrates through the fixed cover and is arranged above the isolation structure; the squeeze rod is movably arranged in the fixed cover through a reset device; the simulation part is sleeved on the squeeze rod; the reset device, two ends of which are respectively connected to the paste discharge simulation structure and the fixed cover; and a liquid injection structure which penetrates through the fixed cover and is communicated to the outer bottle body.

A miniature wave pool system includes a basin for holding water and surrounded and defined by one or more sidewalls. The basin includes a bottom surface that is contoured with at least one upward slope relative to a source of a water flow, to generate at least an appearance of a wave on which a miniature board or skis can be floated against and controlled by a user's fingers. The pool system further includes one or more pumps positioned under the upward slope that defines a compartment for the one or more pumps, the one or more pumps providing the water flow to generate the at least appearance of the wave. The pool system further includes a modular reef that is insertable into and removable from the basin to alter, configure, or arrange a desired bathymetry of the bottom surface of the basin.
