Experience science in the palm of your hand!
Hold the bulb in your palm and watch as the liquid moves up the tube and boils.
You might think it's some sort of crazy chemical with a low boiling point, but really, it's just the air!
When you hold it, the air inside heats up, expands, and forces the liquid up the tube. It then continues to expand and makes it look like it's boiling at the top.
See with your own eyes the gravity-defying act of science with the Hand Boiler.
Note: The ethanol liquid inside does not actually boil. The warmth of your hand creates liquid movement in the tube due to vapor pressure rising.
