About This Product
The hand boiler is a classic demonstration of how heat from the hand makes a liquid and its vapour expand. When a student holds the bulb, the warmth makes the liquid inside boil and rise through the glass loop. Teachers use it with Charles' Law, which links the volume of a gas to its temperature at constant pressure. Because it contains a flammable liquid, an adult must supervise.
