The device in this chapter shows how a thermostat works by turning a lightbulb on and off as the thermostat responds to the heat of the bulb. It can use a gum wrapper or a strip made from paper and aluminum foil to act as a thermostat mechanism. It behaves and demonstrates the same principles as a commercially made device, but is much safer because it does not require high temperatures that are unsafe for young hands.
