Abstract: A multi-ported axle hub and wheel assembly for directing and channeling liquids or dry chemicals under pressure from a single source to a plurality of outlet ports or spray nozzles rotating about the axis of the invention is disclosed. The apparatus can be used to direct and channel liquid or dry chemicals under pressure to, and to provide a source of rotation for, recreational devices such as water toys and for other non-recreational devices where liquid propulsion, liquid mixing or rotational spraying is desired.

Abstract: A water play version of the game of hopscotch is disclosed. A grid of multiple game blocks is provided with each block having one or more small showerhead-type spray nozzles connected by conduit to a water supply. Each spray nozzle is controlled by a pressure-sensitive valve by which water sprays through the nozzle whenever a participant steps or hops onto that particular block. The blocks may be arranged in different patterns to play other games and the spray nozzles may be controlled remotely to allow for surprise or random spraying during gameplay.
