Dino Pet living night light to teach kids about bioluminescence. It may be shaped like a cartoonish Apatosaurus, but the original inspiration for the Dino Pet’s name comes from the dinoflagellates it contains. Specifically, this interactive toy gets its glow from the Pyrocystis fusiformis species of marine algae, which when shaken emit a blue light for a short time. A bottle of algae may sound like a strange pet, but the designers have noted that the dinoflagellates are especially suited to children, since they’re easy to take care of, non-toxic, and will even glow brighter to indicate when they’re being properly cared for. http://youtu.be/zowY47fAhDc
