The Fortune Teller Miracle Fish is a novelty item or kid's toy. It is a  small red plastic fish that will move when you place it on your hand.  Can you use the movements of the toy to predict your future? Well... you  can, but expect about the same level of success as you would get from a  fortune cookie. It doesn't matter, though, because the toy is great fun!
The Fortune Teller Fish is made of the same chemical used in <a href="http://chemistry.about.com/od/howthingsworkfaqs/f/diapers.htm">disposable diapers</a>, <a href="http://chemistry.about.com/od/factsstructures/ig/Chemical-Structures---S/Sodium-Polyacrylate.htm">sodium polyacrylate</a>.  Sodium polyacrylate will grab onto water molecules that it touches,  changing the shape of the molecule. As the molecules change shape, so  does the shape of the fish. If you submerge the fish in water, it won't  be able to bend when you place it on your hand. If you let the fortune  teller fish dry out, it will be good as new.</p>
Science teachers  commonly hand out these fish to students and ask them to explain how  they work. Students propose a hypothesis to describe how the fortune  teller fish works and then can design an experiment to test the  hypothesis. Usually students think the fish may move in response to body  heat or electricity or by absorbing chemicals from the skin (salt, oil,  water).
