Get ready to hear expressions of ooohs & ahhhs when these amazing rocks change color. 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 scientific term for this phenomenon is 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 and more. Recommended for children ages 8 and up.

What's included?

• Ultraviolet illuminator (requires 4 AA batteries, not included)
• 4 fluorescent minerals
• Study guide

How does it work?

Scientifically speaking, the electrons in the rocks absorb this energy. This causes the electrons within the mineral to 'jump shells' and release energy. The human eye can see this released energy in brilliant colors of visible light.
