A water slide is made from a plurality of plastic sheets welded together to form intercommunicating tubes which may be filled with water. Some of the tubes form the side walls of a pool. Other of the tubes form bumps of graduated height to provide a ramp at the end of a slide. A child runs toward the slide, bellyflops on it, slides over the ramp and splashes down in the pool. The water filled tubes additionally provide a shock absorbing effect.
