User:LukeSurl/Fortune Teller Miracle Fish
The Fortune Teller Fish is a small toy. It is a thin red sheet of plastic in the shape of a fish. When placed in the palm of the hand, the fish will distort in one of many possible ways, ostensibly revealing a characteristic of the holder. A slip of paper is used to determine a meaning to the motion of the fish, for instance movement of both the head and tail means "in love".
The fish is made from sodium polyacrylate which is hygroscopic and adsorbs water. Adsorption of water from the hand causes the molecules to distort, different parts of the fish undergo different amounts of adsorption, resulting in the bending and twisting of the fish.[1]
