Nitinol Wire will amazingly shorten in length (with significant force) when electrically powered (or heated by other means). It is easy to use, and the thin strands of wire can lift thousands of times their own weight.Nitinol wire returns to its original length when it cools.The direct linear motion of Muscle Wires offers experimenters a source of motion that is very similar to that of a human muscle, providing possibilities not available with motors or solenoids. (via Nitinol ‘Muscle’ Wire - $3.00 : United Nuclear , Scientific Equipment & Supplies)
this could be pretty useful for something or other.
