This feat of science in action is a fantastic visual demonstration of Charles’ Law, which states that gases expand when heated! Also known as the vapour-liquid equilibrium, this hand boiler is a fun, easy way of demonstrating this scientific principle to the kiddies.
Made of hand crafted glass, you simply hold the base in your hand, and watch as the heat from you hand causes the coloured liquid to move up the narrow tube, bubbling at the top!
- A great way to get kids curious about the science behind common phenomena
- Looks striking on a windowsill or bookshelf
- Assorted colours - comes in green, blue, red & purple. A randomly picked colour will be shipped
