Demonstrate the power of energy transfer with this beautiful glass bubbler, simply hold it at the bottom and watch the liquid rise to the top and then bubble.
Your body heat warms the liquid, causing it to expand and move through a series of tubes to the top chamber, there it starts to bubble.
And if you let go. The liquid cools and slowly moves back down to the lower chamber.
Great for science class, or just to show off to your friends. Collect all 4 colors!
Different versions available: red, purple, blue or green
If you have a preference, please tell us in the order form (‘Order preparation special requests’). Please note that we cannot guarantee your preference in the case a version is out of stock.

- Item Description
Wrap your hand around the bottom of one of these twisty glass sculpted hand bubblers and you will see the liquid “boil” and rise to the top chamber! As your hand warms the bottom, the gas pushes the liquid upwards and it continues going all the way to the top! Just remove your hand and the liquid will start to descend. This is a great demonstration of energy transfer and it’s fun watching the liquid travel up the twisty glass tube. Design and color may vary.
Hand Boilers and fragile and flammable!
What you’ll get:
- One GLASS 6 1/2 ” Inch Hand Boiler Bubbler in assorted random color and design.
Incredible Science Fun Learning Ideas:
- Learn about the relationship between temperature and pressure. As temperature increases, so does the pressure as evidenced by the rising liquid!
- Experiment with different people to see the various body temperature they have which results in different “boil” times. Chart and predict your time!
