This fascinating display of art and science contains active micro-organisms, bright red shrimp, and algae existing in a clear "soup" of filtered sea water. Only light is needed to keep their world in a perfect plant-and-animal balance: algae and bacteria are eaten by the shrimp whose waste supports their regeneration. Created with technology developed by scientists at NASA. No maintenance required.
