 * HOW DOES GLOW IN THE DARK PAINT WORK? **

Glow in the dark paint is used in many ways. Some are used for street signs and road markings, so they can be seen day or night. Some are used for just painting projects. There are a couple of different ways to make paint that glows in the dark. I will explain those here.

Put info here… Luminous paint: One type of glow in the dark paint glows in the dark after absorbing and releasing light sources such as UV rays. Phosphor, which is a chemical substance, is added to the paint. When the paint is exposed to light, the phosphors absorb the light and are energized. The phosphors begin to lose this energy and release it as light of their own. This causes the paint to glow which you can only see in the dark. The glow will fade over time, but when exposed to light again, the process starts over again. Light is absorbed again by the phosphors and released again to make the paint glow.
