Hand Boiler - Petrosains

Hand Boiler


Boil the liquid with your body temperature! Hand Boilers are glass sculptures containing a liquid that will ‘boil’ as heat is transferred from your bare hands. Simply cup the lower chamber of the Hand Boiler within the palm of your hand and watch how your body heat will cause the liquid inside to boil and rise through the tube into the upper chamber.

Hand Boilers perfectly demonstrates the concept of energy transfer, Charles’s Law, and vapour-liquid equilibrium. The coloured liquid in the boiler is comprised of a volatile mixture of liquid (Methylene Chloride) that have a boiling point just above room temperature. The body heat from your hand causes the liquid to boil, which in turn makes the liquid evaporate, turning it into gas. The expanding gas pushes the liquid upwards and when you release your hand, equilibrium is re-established. The gas condenses into a liquid again and flows back into the lower bulb.
