A presentation on COLOR & ENERGY… Learn the scientific concepts behind why rocks glow in the dark.

This video provides an in-depth look into the science behind fluorescent minerals, presented by Bob Oblack. It covers the science of color and energy, luminescence and fluorescence.
The presentation also describes why only some minerals fluoresce, the role of activators, and how different UV wavelengths can alter color. Other types of luminescence are also discussed, with historical and modern applications of UV light.
