FORT WAYNE, Ind. (21Alive) -- In this week's episode of Cool Science Monday, Martin Fisher from Science Central will talk about "cool" light called phosphorescence.

Martin used our updated exhibit, a wall painted with phosphorescent paint, and small light wands/flashlights. By shining the light onto the wall, a pattern of light would appear on the wall, and then slowly fade away.

Phosphorescence is when a material absorbs light, and slowly releases the light over the time. Because only light is emitted, not heat like with an incandescent light bulb, it’s sometimes called cool light.
