Abstract: There is provided an apparatus and a method for producing a play compound and the play compound itself which, in one embodiment is a compound which sufficiently fluid to be pliable and is typically cold and slimy to the touch. The apparatus and a method provide a powder and liquid to a user, which can be a non-skilled person and thereby allow the mixing of the powder and liquid together by that person to form the play compound outside of a factory environment whilst ensuring that the play compound which is formed has the desired characteristics. Most typically the user which performs the mixing can be the end user, such as a child, who will play with the compound and so the formation of the play compound forms a new part of the play experience.

Abstract: A system for vacuuming out sediment when installed on the inside of a gravity feed, elevated potable water tank or tower holding water at a pressure head of the kind having a riser serving as a water inlet and outlet. The system having a rotating manifold driven by a rotational drive mechanism installed along the bottom wall of the tank or tower connected to a plurality of downwardly directed nozzles. The rotating manifold is connected to a drain pipe passing down through the or alongside the tank riser and is supported so that the nozzles are positioned above the bottom wall in the vicinity of the sediment. When water is allowed to flow through the drain pipe, the pressure head causes sediment which may otherwise be a health risk and promote electrolytic corrosion to be vacuumed out by the nozzles.
