Inside every raindrop, hidden laws of light paint the sky.
Discover how rainbows form, why every observer sees a different one, and how scientists captured elusive higher-order arcs once thought impossible to photograph. From fire hose experiments to precision instruments scanning distant worlds for polarized light, this film turns a familiar sight into a gateway to optics, discovery, and the search for habitable planets.
