ABSTRACT:
The invention provides a unique interactive waterfall-climbing structure. The invention provides a tower, based on the use of polystyrene foam, cut into various shapes to create a series of descending depressions and ledges to simulate a waterfall. The foam mold is covered with fiberglass to form a rigid, solid single panel. A steel frame is then attached to the one-piece fiberglass shell, allowing the structure to stand self-supported. The invention also provides a waterfall system including a dispensing tank at the top to allow water to overflow outward and cascade down the climbing surface and a reservoir tank to collect the water. The invention further provides a pump for re-circulating the water and a conduit to direct water from the reservoir upwardly to the dispensing tank.
