A rough four-tiered scaffolding placed in a pool of shallow water supports four rectangular metal basins, one on each level. A system of pumps and hoses shoots jets of water upwards, from basin to basin, reversing the usual gravitational flow. The water sprays wildly, not restricting itself to the basins and pool but also dampening the immediate surroundings. The sound of splashing water is clearly audible over the murmuring of the electric pumps, and the air is filled with a subtle sensation of moisture. Reversed waterfall has been shown both indoors and out.
