Certain unique and scarce minerals have the ability to absorb ultraviolet light and literally change color. Some might call it "glow-in-the-dark" but the true scientists refers to this phenomenon as fluorescence. The kit includes a long UV light and four ordinary-looking rocks that reveal cool fluorescent colors under the black light. The kit comes with instructions that explain ultraviolet and visible light, some everyday uses of fluorescence
