Description
 

Are you hot enough to boil liquid with your bare hand? Yes, you are! Glass Hand Boilers are looped and twisted hand-blown glass sculptures containing liquid that will boil as heat is transferred from your bare hand. Fascinating and pretty! This quality Glass Hand Boiler is a fun and exciting way to demonstrate Charlie's Law (when temperature goes up, so does pressure) and energy transfer.

Hold the Glass Hand Bubbler in your hand, and within moments, the liquid will shoot up the tube from the bottom bulb to the top, and begin to bubble and boil! It looks like magic, but it's simply science! When the gas in the bottom bulb is heated by your hand, the increased temperature creates increased air pressure. This increased pressure pushes the liquid up the tube to the top bulb. When all of the liquid transfers from the bottom bulb, air bubbles are forced up the tube, causing the liquid in the top bulb to "boil."
