Electrolycra Strip 100Mmx1450Mm Age 4-5 Mounted on a sturdy standThis material looks and feels like ordinary Lycra but is highly conductive. It can be cut into narrow strips to form conducting wires or can be used as a soft compliant substitute for metal and foil in switches and sensors. Amazingly, its conductivity depends how tightly it is stretched so if you pull it, the resistance increases (and drops again when stretched very tightly). In a thin strip, the material also warms up when current is passed thus
