3-D Sidewalk Chalk Ultimate Activity Set from Crayola

The physics behind the method is sound (see the Chromatek dot com site) so you needn't doubt if this works. Take a few moments to learn how it works and you will have the makings of a science fair project. When you run out of chalk, keep the glasses and get fluorescent paints at the craft store, because you can do this indoors on walls, paper, etc. The results are fabulous with black light! You get different effects with white versus black backgrounds. You can even make 3-D displays on your computer...
