Why do these Celestial Shapes glow in the dark?
The glow-in-the-dark shapes are made with a special formula of phosphorescent pigment called Glominite, which is mixed into the products during manufacturing. Glominite stores light, then gradually releases it. It is safety-tested & never wears out, so the glowing effect is always rechargeable by light. Expose the stars to light for one minute. Then, turn off the lights & watch them glow!
All “glow-in-the-dark” products contain phosphors and have to be “charged” in order to attain a good glow. A phosphor is a substance that radiates visible light after being energized. After being exposed to light, most items will glow for at least 10 minutes. You may need to be in nearly complete darkness to notice it. The brighter the light and the longer the exposure, the better and longer the item will glow.
