Abstract: A waterslide play apparatus includes a stairway having a landing every two feet of vertical elevation. The stairway includes a 90 degree turn about half-way between the top and the bottom thereof. A waterslide has an upper end connected to an upper landing at the top of the stairway. The waterslide has a 180 degree bend so that the waterslide is adjacent the stairway for most of its length. Various water forming devices are positioned over the slide for expelling water onto people sliding down the slide. The devices are actuated by valves located on the stairway to permit people ascending the stairs to ride the slide to expel water onto those sliding down the slide.

Abstract: An endoskeletal or exoskeletal participatory water play structure comprised of play elements, water carrying conduits with attached water forming devices, associated valves, and issuing water effects, all of which define a three dimensional structure whereupon participants can manipulate valves to cause controllable changes in water effects that issue from the various water forming devices, and thus, alter the embodiment's overall appearance, sound and feel resulting in participant and observer recreational enjoyment.
