Abstract: The present invention provides a water slide which includes a device for reducing the impact felt by riders or users when they contact the slower-moving water at the bottom of an incline. Such slower moving water can be particularly injurious to a user who is traveling at relatively high speed (e.g., down a particularly long or steep slope). The device for reducing impact is a section of slide of predetermined length which includes air injection nozzles for reducing the apparent density and viscosity and increasing compressibility of the water to enable the user to slow down more gradually by transitioning from reduced density water to normal density water.

First Claim:
Show all 25 claims
What is claimed is:     1. A water slide comprising:
  • an entry zone elevated more than about 80 feet above ground level;
  • an inclined, substantially continuous sliding surface having an uphill end connected to the elevated entry zone and a downhill end extending away from said entry zone, said inclined sliding surface having a slope forming an acute angle with horizontal of at least about 60 degrees;
  • a relatively level sliding surface having an uphill end continuous with the downhill end of the inclined sliding surface and a downhill end extending away from said inclined sliding surface, said level sliding surface having sufficient length decelerate a user; and,
  • a means for creating a flow of water over the inclined sliding surface and the level sliding surface;
  • said level sliding surface including a means for injecting air into the flow of water passing over it, whereby a reduction of apparent density of said water will occur.
