Recommended for ages 8 to 16 years

Hand Boilers are looped and twisted glass sculptures containing a liquid that will "boil" as heat is transferred from your bare hand—demonstrating energy transfer in a cool, fun way! Hold the bottom chamber in your hand and watch as your body heat warms the liquid. As it starts to vaporize, it expands moving through the tubes to the upper chamber. When all the liquid has reached the top, a bubbling effect is created! Let go and the liquid cools, moving back down to the lower chamber. Great for science class!

Please select your color choice above: red, blue, purple or green.

  • Hand Boiler demonstrates Charles’s Law of vapor-liquid equilibrium. The heat from your hand quickly warms the volatile solution of liquid and gases, the liquid rises through the cool tube, and bubbles at the top. 
  • Made from sculpted glass, the Hand Boiler measures approx. 2 x 2 x 7 inches (LxWxH).
  • Available in four color choices: Red, blue, purple or green.
  • Cool thermodynamics lesson for kids; art in motion for adults
