Grow your own crystal geode that fluoresces under UV light with this brilliant project kit! A geode is a rock that forms with a crystal filled cavity inside, and so this kit allows you to cast a plaster geode shell filled with crystal growing alum salt solution. The solution has an ultra violet pigment mixed into it so that when the crystals grow, they glow! Shine the UV torch included onto the crystals inside the geode, and they will fluoresce brightly glowing in an enchanting display! The brilliant project kit contains everything you need to make your own crystal geode learning all about crystals and their structure as well as the ins and outs of fluorescence.
