Description
- Body Heat Utilization- Experience the unbelievable process where our hand boiler boils liquid using nothing but your body heat. Observe as the heated liquid rises up through the tubes and into the upper container.
- Unique Heat- More than just a toy, it's a fascinating science revelation. Our science toys contains a specially designed twisted glass with a unique liquid that boils upon with heat transferred from your bare hand.
- Energy Transfer Demonstration - Science has never been more interesting. Once you remove your hand, it takes a few minutes for office toys liquid to cool down and return to the bulb, a compelling display of energy transfer.
- Vapour-Liquid Equilibrium Proof - Watch scientific theories practically demonstrated with our hand boiler science toy. The colorful liquid inside illustrates vapour-liquid equilibrium as it has a boiling point just room temperature.
- Hand Heat Energy Mechanism- Experience the of science with your very own hands. The heat from your hands causes the hand boilers liquid to boil, turn into gas and push the liquid upwards. Once equilibrium is re-established, the gas condenses back into liquid and flows back to the lower bulb.
