Hand Boilers are glass sculptures containing a liquid that will ‘boil’ as heat is transferred from your bare hands. Boil the liquid at your body temperature! 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 comprises a volatile liquid mixture (Methylene Chloride) with a boiling point just above room temperature. The body heat from your hand causes the fluid to boil, which makes the liquid evaporate, turning it into gas. The expanding gas pushes the liquid upwards, and equilibrium is re-established when you release your hand. The gas condenses into a liquid and flows back into the lower bulb.
The Hand Boiler is a fascinating STEM toy demonstrating several scientific properties that trigger children’s curiosity and interest in Science. It allows students to learn about physics in a fun and unique way. For students, teachers, and parents, the Hand Boiler is the perfect choice for a simple but educational toy.
