A Berry So Shiny, It's Irresistible (And Inedible)
This berry is the shiniest known thing in the world! It's skin has no pigment — no colored cells. Rather, all the cells are coiled in a peculiar twist. The cells form sheets, like the skin of an onion. Light filters down through those layers in a way that creates something called "structural color." "So what they do, basically, is they bounce back the blue light, and they let the rest of the light through," Steiner explains.
