Product InformationHand Boilers are looped and twisted glass sculptures containing a liquid that will "boil" with the heat from your bare hand. Simply hold the large bulb end in the palm of your hand. In a few minutes your body heat will cause the liquid to start to rise. Once out of your hands, it takes a few minutes for the liquid to cool down and return to the large bulb.Pretty fascinating science toy. Excellent demonstration of energy transfer. Comes in three different colors: blue, green and red - let us pick one for you. Tell a Friend about this item
