Product Description
Novelty Science Toy -- Hand Boiler, Glass Love Meter (colors and shapes vary)
- bubbles and boils when held in your hand
- novelty glass toy
- physics / chemistry demostration
- colorful and unique decoration on a shelf
It is a pretty fascinating science toy and an excellent demonstration of energy transfer.
Hand Boilers come in several different colors including: blue, green, yellow, purple and red and several different loop shapes.
Hand boilers demonstrate Charles's Law and vapor-liquid equilibrium.
The colored liquid in the boiler is comprised of a volatile mixture of liquids that have a boiling point just above room temperature. The body heat from your hand causes the liquid to boil, which in turn makes the liquid evaporate, turning it to gas. The expanding gas pushes the liquid upwards and when you release your hand, equilibrium is re-established. The gas condenses into a liquid again and flows back into the lower bulb.
