The balls float are coated with a chemical that blocks ultraviolet light and helps the spheres last as long as 25 years. Overall, the balls are expected to keep around 300 million gallons of water from evaporating in the reservoir each year. The plastic shade balls also form a protective barrier across the surface that helps keep birds, animals and other contaminants out. Watch the video below.
