Westminster Hand Boilers (Green)
Hand Boilers are looped in the twisted 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. Pretty fascinating science toy and an excellent demonstration of energy transfer.
