Product Description

  • Boils the liquid with your own body temperature. Hold the lower chamber in your palm and watch how the liquid boils and rises through the tubes in to the top chamber
  • Hand boilers are looped and twisted glass sculptures containing a liquid that will boil as heat is transferred from your bare hand
  • Once out of your hands, it takes a few minutes for the liquid to cool down and return to the large bulb. It is pretty fascinating science toy and an excellent demonstration of the energy transfer

    • blue
    • green
    • purple 
    • red
  • Hand boilers demonstrate Charles's Law and vapor-liquid equilibrium. The colored liquid in the boiler is comprise of the volatile mixture of liquids than 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 in to gas. The expanding gas pushes the liquid upwards and when you release your hand, equilibrium is re-established. The gas condenses in to a liquid again and flows back in to the lower bulb

Package include

  • 1x Hand boiler
