Demonstrate the power of energy transfer with this visually intriguing liquid motion toy. Show your friends just how hot you are by holding this bubbler in your hand and making the liquid rise to the top and then boil.

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. Colors vary.
