Features:
1.The Office Thinking Hand Pot is suitable as a tool for learning energy transfer and is widely used in student classrooms. It can also be placed anywhere in the living room as an ornament to decorate your home.
2.Hand boilers demonstrate Charles's Law and vapor-liquid equilibrium. The colored 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.
3.Hand Boilers are looped in the glass sculptures containing a liquid that will ""boil"" as heat is transferred from your bare hand. Simply hold the large bulb end on the bottom in the palm of your hand and within minutes, your body heat from your hand will cause the liquid to rise. Once out of your hands, it takes a few minutes for the liquid to cool down. It is a pretty fascinating science toy and an excellent demonstration of energy transfer.
