You can freely build on How the First Modern Water Slide Was Designed

What this patent covers

This patent describes a structure designed for aquatic recreation, specifically a slide that uses a continuous flow of water to reduce friction for a person sliding down. The design includes a ramp or chute surface with a water distribution system at the top that ensures the entire sliding path remains lubricated. By maintaining a thin film of water, the device allows a user to glide from an elevated position into a pool or landing area at the bottom.
