Fluorescence Experiment Kit
Learn about the amazing phenomenon of fluorescence.  Certain unique and scarce minerals have the ability to absorb ultraviolet light.  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.  Kit includes: ultraviolet illuminator (requires 4 AA batteries, not included), 4 fluorescent minerals and study guide.
