Comes with a black (UV) light that enables you to see the fluorescent quality in the six rocks included in the kit. Also includes a booklet for other experiments to try with the black light.  We recommend then taking your kids outside to see what kind of rocks they can find and then start a journal.  School-aged kids love collecting and it's a great way to encourage your kids to do a little reading and research. This is one of those kits that can inspire a long term hobby.  There are also quarries in parts of the country where you can go "dig" for your own fluorescent rocks!
