Black lights: Seeing minerals in a whole 'new light' and on a budget, Falls of the Ohio State Park

Black lights used to be expensive for collectors of fluorescent minerals and roller rinks. Today, the cost has come way down. This program by Jim Lobb, a local collector, will introduce you to the colorful world revealed by the ultraviolet lamp. Why are some minerals so vibrant colored and others don't show any change? Where can I buy a cheap and safe black light? Can I find fluorescent minerals, or should I buy them? They make a great holiday gift for budding scientists. Free program, though pay-to-park applies.
