Halloween Science: Spooky Glow in the Dark Jars

We really hope this activity will excite all of you but it is important to know how glow in the dark material works:

Glow paints do not contain light in them. But they do have a pigment known as phosphor that makes them glow in the dark. Phosphor can accumulate light energy like  from the sun and when it's dark, it glows. When phosphor comes in contact with sun or any other form of light it absorbs the photons and later in the dark, the paint emits these photons. The photons thus released emit a phosphorescent glow. This process is known as photoluminescence.

One more day till Halloween and one more exciting activity! Happy Haunting!
