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.Product FAQ

Flourescent Rocks
Brian Packham Anderson, CA USA - January 25, 2010
I received the box of rocks and a very tiny black light. The rock samples were very small and did not show the glow very well with the tiny black light. Overall I was dissapointed with this product. Brian we are sorry you were not happy with the product. Someone from our customer service team will be calling you to discuss your concerns in the near future. -- Steve Spangler Science Web Team |
