Hands Down, an Edmund Classic! — Hand Boilers are looped and twisted glasssculptures containing a liquid that will “boil” as heat is transferred fromyour bare hand. Simply hold the large bulb end in the palm of your hand andwithin minutes, your body heat will cause the liquid to rise. – Once out ofyour hands, it takes a few minutes for the liquid to cool down and return tothe large bulb. Pretty fascinating science toy and an excellent demonstrationof energy transfer. Comes in three different colors: blue, green and red – letus pick one for you.
