Glow in the Dark & Chemiluminescence

Explore the science of chemiluminescence, light without heat! We have 6 inch and 4 inch light sticks, and mini light sticks. Phosphorescent Vinyl Sheets absorb light and slowly emit it over a few minutes. Glow-in-the-Dark Pigment is used to make paint and other products glow in the dark. The Spy Pen writes with invisible ink. Use the special, attached ultraviolet light at the other end to read the message.
