A hand boiler or love meter is a glass sculpture used as an experimental tool to demonstrate Charles's Law and vapor-liquid equilibrium or as a collector's item to measure love. It consists of a lower bulb containing a volatile liquid and a mixture of gases that is connected usually by a twisting glass tube that connects to an upper or "receiving" glass bulb.
