The Cool Blue Light Experiment Kit uses copper sulfate, perborate and luminol to produce light from the energy released in a chemical reaction. The instructions recommend this kit for experimenters nine years old and up, with adult supervision. Some experiments call for the addition of household chemicals like chlorine bleach, hydrogen peroxide or sugar.

Give posters, glasses, maybe sweatshirts (we didn't test it on fabric) a warm GLOW. The goo in the 1/3-oz tube is the consistency of white glue and works just like it, but comes in pastel pink, peach, green and yellow, all of which glow in the dark. It has a narrow writing tip under a screw cap. We'll pick at least (2) different colors for you.
