This glass hand boiler is such fun to experiment with! 

Hold the bottom bulb to heat the liquid. This will cause an increase in air pressure, sending the liquid up and into the top bulb. Once all the liquid reaches the top, air bubbles follow, which cause the liquid to bubble! 

If you'd prefer a specific colour, please specify in the order notes.
