Westminster Hand Boilers (Colors May Vary)
Description
Hands Down, an Edmund Classic! — Hand Boilers are looped and twisted glass
sculptures containing a liquid that will “boil” as heat is transferred from
your bare hand. Simply hold the large bulb end in the palm of your hand and
within minutes, your body heat will cause the liquid 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 and an excellent demonstration
of energy transfer. Comes in three different colors: blue, green and red – let
us pick one for you.
