Why Do Things Fade in the Sun?

The video discusses how sunlight, particularly UV light, causes colors to fade and plastics to degrade through a process called photodegradation. This process affects pigments and dyes by breaking chemical bonds, leading to color loss. While this is a minor issue for window displays, it poses significant risks to artworks and certain plastics. The video also covers methods to mitigate UV damage, such as using UV-resistant chemicals.
