National Geographic - Glow-In-The-Dark Putty

Description

Hit the lights to see this incredible putty shine! Glow in the Dark Putty bends, stretches and bounces just like normal putty, but it's infused with chemistry magic that makes it glow. Use the UV Laser Light to draw cool designs and see them shine brighter than the already glowing putty. It's tons of fun to play with and never dries out. Kit includes one UV Laser Light, a handy storage tin and a fascinating, full-color Learning Guide that explores the science behind fluorescence.
