Frasier: Oh, now, Carla, don't prey on their gullibility. There's nothing magical about it. It's just a simple chemical reaction. When you crunch down on a Lifesaver, electrons strike nitrogen molecules, which causes the latter to emit an invisible ultraviolet radiation which, when absorbed by the methyl salicilate in the Wintergreen flavoring, produces a flash of blue light.
