Description

• Boiling Principle: The measurement of this toy is based on the speed at which the liquid boils to the topJust hold the larger bulb in the palm of your hand, and then gently clasp it with your handThen wait a few minutes for the heat of the body to transfer to the glass, which can cause the liquid to riseBe careful, it is made of glass and very fragile.
• Fun and Educational: Hold the lower container with your hand and observe how the liquid boils and rises to the upper container through the tube – a great way to learn about energy transfer!
• RING SHAPE: It is a ring shaped and twisted glass toy with a liquid in it that boils when heat is transferred from your bare hands.
• Easy to Use: Once leave your hand, it takes a few minutes for the liquid to cool and return to the container below, which is a very interesting science toy and a great demonstration of energy transfer.
• Fascinating Scientific Toy: The heat on your hand causes the liquid to boil, causing the liquid to evaporate into a gas. The expanding gas pushes the liquid upward, and when you release your hand, the equilibrium is re-established. The gas condenses again into a liquid and flows back to the container below.

Feature:
1. It’s a ring-shaped and twisted glass toy with a liquid in it that boils when heat is transferred from your bare hands.
2. It proves the vapour-liquid equilibrium, the colored liquid in the container is a volatile mixture with a boiling point just above room temperature.
3. Boil this liquid at your body temperature, hold the lower container with your hand, and observe how the liquid boils and rises through the tube to the upper container.
4. Once leave your hand, it takes a few minutes for the liquid to cool and return to the container below, which is a very interesting science toy and a great demonstration of energy transfer.
5. The heat on your hand causes the liquid to boil, causing the liquid to evaporate into a gas. The expanding gas pushes the liquid upward, and when you release your hand, the equilibrium is re-established. The gas condenses again into a liquid and flows back to the container below.
