Hand Boiler: heat in action
A scientific experiment in your hand
Franklin’s Boiling Pot is a fun way to introduce children to energy transfer. Grab hold of the bottom container and your heat will cause a chemical reaction, causing the colored liquid in the tube to rise impressively. The bottom container empties and the top one fills up. When the liquid has finished rising, it starts to boil! All in a matter of seconds.

Frequently Asked Questions
How does the Hand Boiler work?
When you hold the bottom bulb, the warmth of your hand heats the liquid inside. This raises the vapour pressure, which pushes the coloured liquid up the tube into the top bulb, where it bubbles as if boiling.
Is there a chemical reaction inside?
No. It is a physical change, not a chemical one. The liquid evaporates and moves because of heat from your hand, and it can be repeated as the liquid flows back.
How big is it and what is it made of?
It is made of glass and stands 16.5 cm tall. As with any glass object, handle it carefully and keep it away from hard surfaces.
What is the Benjamin Franklin connection?
The product text says Franklin came across this device in Germany and made an improved version, rather than inventing it himself. It is sometimes called Franklin’s boiling pot.

Bought it as a desk toy, and it works a treat. The colours are vibrant, though a tiny bit of paint chipped off on the base after some use. Still quite happy with it.
