Can be trained to remember new shapes. Twist wire into a different shape then by heating the wire red hot with a candle flame it will remember the new shape. See PDF file for more information.

Nitinol Memory Wire 3" Sections
These 3" samples of memory wire can be wound around a pencil to form a coil. When immersed in hot water, the wire returns to its original shape. The wires can be "set" into other shapes, using a candle flame. These wires have a smaller diameter than our memory wire by the foot.
Nitinol Wire Samples are priced per 3" piece
Fun and educational! You can bend it while cold, then heat it in hot water, and it will straighten quite forcefully. You can modify the remembered shape by annealing the wire. For more information Click Here.
