The Rainball is a children’s pool where coloured balls rain down under water curtains. The circular design of the aquatic space allows for a central overflow ring that drains the cascading water. The circulation current drags the balls through a safety barrier, towards the multicolour centre. The underground plantroom houses a device that separates the balls from the water.

A conventional hydraulic installation supplies the structure’s water curtains. The balls are propelled with compressed air through transparent tubes under the decking to produce the rain of balls over the pool. The entire structure, which can be produced in different colours, is surrounded by extensive nets that prevent the balls from leaving the attraction.
