About this item
- ?Boil the liquid with your body temperature and observe how the liquid boils and rises through the tubes into the upper container
- ?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 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

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
