A water play structure (100) includes a frame base (102), a telescoping hollow frame column (112) supported in a vertical orientation and stabilized by the frame base, and a plurality of frame arms (110, 118). Each frame arm extends horizontally radially outward from, and mounted to, one of the frame base or the telescoping hollow frame column. An outward distal end of a first frame arm includes a first interface structure, and each water play station (108, 202), selected from a plurality of different water play stations, includes a second interface structure. The first interface structure and the second interface structure are standardized mutually compatible interface structures which allow different water play stations to be coupled to, and used with, each frame arm in a modular implementation.

A rotatable sprinkler comprises a base with a continuous curved surface and a rotation element disposed rotatably and relatively to the base. The rotation element has an outlet that connects to a water source. A decorative unit is disposed on a support, part of which is located on the rotation element and the free end of which is in contact with the continuous curved surface of the base. Therefore, the decorative unit may rotate relatively to the base, or move up and down when the free end of the support is pressed against the continuous curved surface.

A paddling method for a craft is provided, which is a method for driving a rotating ring to float and rotate by the dynamic force of water. The rotating ring comprises a rotating inner ring and a rotating outer ring, at least three connectors are connected between the rotating inner ring and the rotating outer ring, an external part of the connector is provided with a rotating blade, and the rotating blade is placed in water in a water-sealing container. The paddling method for the craft of the present invention has advantages of being novel in conception and design, good in rotating scenery effects, good in impression and the like.

A water apparatus attachable to a water source may include a nozzle and one or more light sources approximate the circumference of the nozzle, such that the one or more light sources project light into a water stream projected from the nozzle.

The system is a type of gliding device capable of gliding through different mediums, such as water. The body of the gliding device is comprised of buoyant material and is ideally chosen based on the best material to utilize the hydrographic printing process. The body encourages the system to rise in water and wings extend from the body and resist vertical motion providing little resistance to forward motion. A third wing may extend from the distal end of the body and have a rudder pivotably connected thereto, allowing a user to manipulate the flight path of the system through the water while the system slowly rises to the surface.
