Character based games and methods of play are provided. In preferred embodiments, the character based games include hydrophobic game boards that use characters formed from water or other liquids with surrounded or suspended character features. In a preferred embodiment, a method of play is provided. The method of play comprises: adding a character feature to water; placing the water including the character feature on a hydrophobic play surface such that the water forms a bead surrounding the character feature; and manipulating the hydrophobic play surface to cause the bead of water including the character feature to move to different locations on the play surface.

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.

An apparatus or educational toy comprising a main body (120, 220, 320, 520) and a drive mechanism (140, 240, 340, 540), wherein the drive mechanism (140, 240, 340, 540) comprises a reservoir (142, 242, 342) for storing a driving liquid, a discharge outlet (144, 244a, 244b, 344, 544a, 544b) through which the driving liquid is discharged from the main body (120, 220, 320, 520) to generate a driving thrust, a liquid delivery path (146, 246a, 246b, 346) for delivering the driving liquid for a reservoir outlet (148, 348, 448) to the discharge outlet (144, 244a, 244b, 344, 544a, 544b), and a threshold setting device (147, 347); and wherein the threshold setting device (147, 347) sets a threshold thrust level so that the driving liquid is to pass from the reservoir (142, 242, 342) and discharged from the discharge outlet (144, 244a, 244b, 344, 544a, 544b) upon reaching the threshold thrust level during operation.

A rotary displacement structure of a fun device includes a container body. The container body has a space therein. A fluid is provided in the space. A rotary displacement unit is disposed in the space. The rotary displacement unit has buoyancy or gravity. The rotary displacement unit includes at least one blade assembly. When the container body is overturned, the rotary displacement unit will rise or descend through buoyancy or gravity. At the same time, the blade assembly enables the rotary displacement unit to rotate when ascending or descending, so as to obtain a different visual effect from the prior art.

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.
