About This Product
A compound bar, also called a bimetallic strip, is made of two metals bonded together. The two metals expand by different amounts when heated, so the strip bends. In school physics it is held over a flame or hot water to show unequal expansion, and the idea is then linked to uses such as thermostats and fire alarms. A thin strip responds quickly, which suits a classroom demonstration.
