Glow-in-the-dark paint is a special type of paint that absorbs light and then emits it in the dark. It contains phosphorescent materials, which store energy from light sources like sunlight or artificial lights. When the lights go out, the paint glows for a period of time, creating a luminous effect. This paint is commonly used for various applications, including art projects, safety signs, and decorative items. It comes in different colors and can be applied to various surfaces, such as walls, wood, and fabric. The glow can last from a few minutes to several hours, depending on the paint's quality and the amount of light it absorbed.
