Become a UV detective with our photochromic powder, which detects ultraviolet rays from the sun!  Instead of using your delicate skin as an ultra-violet light (UV) detector, use this special photon detecting powder that changes colour when exposed to UV light!

What does photochromic mean? Well, "photo" comes from the greek word light, and "chromo" comes from the greek word for colour... meaning that it is colour changing when exposed to different light wavelengths!

This little photochromic powder kit is sure to provide hours of fun with photons and making paint. Paint different objects and see how they change colour in different light and dark environments, all while learning about photochemical reactions!
