Product Description

Hand Boilers are looped and twisted glass sculptures containing a liquid that will "boil" as heat is transferred from your bare hand. Simply hold the large bulb end in the of your hand and within minutes, your body heat will cause the liquid to rise. Once out of your hands, it takes a few minutes for the liquid to cool down and return to the large bulb. It is a pretty fascinating science toy and an excellent demonstration of energy transfer. Hand Boilers come in several different colours including: blue, green, yellow, purple and red and several different loop shapes - yours will be randomly picked and shipped. Hand boilers demonstrate Charles's Law and vapour-liquid equilibrium. The coloured liquid in the boiler is comprised of a volatile mixture of liquids 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 to 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.
