Glowing Rocks

Ohio History

Glow-in-the-Dark Exhibit

This was such a neat geology exhibit, I just had to include it. This display looked like ordinary rocks, until you flipped a switch and they came alive with color! From deep blue to electric green, red, and royal purple, these rocks shimmered with light. They slowly became more intense, then faded away. Scientifically, it was a special ultraviolet light that caused certain metals in the rocks to begin emitting light. We had never seen anything like it before!
