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.
