Smart Wires and Muscle Kit
The smart wire demo kit provides a clear and simple way of introducing the principles of the shape memory effect. The kit uses two pieces of thin smart wire connected to a lever on either side of a pivot. When a battery is connected to one of the smart wires, the wire contracts (by about 5%) and the lever moves. If the battery is disconnected, and current is now passed through the other wire, the lever moves back in the opposite direction. Stackable plug leads and cell holder not included. Kit includes 10 meters of wire plus a booklet.
