Glowing Tonic WaterGlowing Tonic Water
Make a Glowing Geyser

Tonic water might not be your first choice for a beverage, but you might learn to like it more when you discover its glowing blue color under black light. The secret is a chemical in the tonic water called quinine, a substance that naturally fluorescences an eerie bluish color under black light. Make a tray of ice cubes using tonic water and add them to a colorless beverage like Sprite or 7-Up. The glowing cubes look great under black light. But the best is maybe a glowing tonic geyser... check out Steve Spangler’s video to see how he turned the Mentos Geyser into a glowing liquid light.
