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!

Height : 16.5 cm

Different versions available: red, purple, blue or green
