- ✔Boil the liquid with your body temperature and observe how the liquid boils and rises through the tubes into the upper container
- ✔It is a looped and twisted glass containing a liquid that will ”boil” as heat is transferred from your bare hand, very interesting
- ✔Once leave your hand, it takes a few minutes for the liquid to cool down and return to the large bulb. This is a very interesting science toy and a great demonstration of energy transfer
- ✔ This toy proves the vapour-liquid equilibrium, the colored liquid in the toy is a volatile mixture with a boiling point just above room temperature
- ✔The heat on your hands causes the liquid to boil, and the boiling evaporates the liquid into a gas. The expanding gas pushes the liquid upward, and when you release your hand, the equilibrium is re-established
