Plankton Makes This Dinosaur Toy Glow, Batteries Not Required

As the story goes, the folks at BioPop were trying to make a sustainable light that relied on something other than man-made batteries. They tried using a bioluminescent plankton called dinoflagellates, but the tiny creatures required too much intervention to be a practical light source. They would, however, make for a really neat desk toy, and so the aptly-named Dino Pet was born.
