Hand Boiler - Randomly Selected

This Hand Boiler magically demonstrates energy transfer in a cool, fun way! Hold the bottom chamber in your hand and watch as your body heat warms the liquid. As it starts to vaporize, it expands moving through the tubes to the upper chamber. When all the liquid has reached the top, a bubbling effect is created! Let go and the liquid cools moving back down to the lower chamber.
