From NPR News: Some People Really Can Taste the Rainbow

In fact, most of us can. It’s sherbert flavored, of course. But not rainbow sherbert. It’s some kind of berry. We don’t know which one. Tasting it is easy. Finding it is tough. You find rainbows out there but can’t track them down. Some people—scientists and meteorologists mostly but plumbers and social workers too—claim that one can’t find the end of a rainbow. The point where it touches down. And they’re right. One can’t. But if you travel in pairs and threes and fours, most anything can be tracked down. I’ve been on expeditions to the dividing moment between day and night and the point at which fog ends. Finding the ends of rainbows is easy. And when we do, we eat up its berry goodness as though it will melt away. Because it does. Leaving just the hint of some berry on our tongues. We don’t know which one.
