Learn about 

Are you hot enough to boil liquid with your bare hand? Yes, you are! 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 Hand Boiler from Tedco Toys is a fun and exciting way to demonstrate Charle's Law (when temperature goes up, so does pressure) and energy transfer.

Hold the Hand Boiler 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."

Hand boiler is 6.5" tall and bulbs are approximately 1" in diameter.

NOTE: Hand Boilers are not toys, and are intended for educational demonstration.  Never heat, as this could cause the product to explode.  Recommended for ages 12+.
