How the Liquid Works
The liquid inside reusable ice cubes works by absorbing and releasing heat energy. When you place the ice cube in a drink, the liquid inside the cube absorbs heat energy from the drink, causing it to change phase from solid to liquid. As the liquid absorbs heat energy, it expands and becomes less dense than the surrounding liquid. This causes the liquid to rise to the top of the cube, where it releases its heat energy to the surrounding environment.
The Science Behind Phase Change
The phase change process that occurs in reusable ice cubes is based on the principles of thermodynamics. When a substance changes phase from solid to liquid, it absorbs heat energy from its surroundings. This heat energy is used to break the bonds between the molecules of the substance, allowing it to change phase.
In the case of reusable ice cubes, the liquid inside the cube absorbs heat energy from the drink, causing it to change phase from solid to liquid. As the liquid absorbs heat energy, it expands and becomes less dense than the surrounding liquid. This causes the liquid to rise to the top of the cube, where it releases its heat energy to the surrounding environment.

What are reusable ice cubes and how do they work?
Reusable ice cubes are innovative products designed to replace traditional ice cubes in cooling beverages. They are typically made of a flexible plastic or silicone material filled with a liquid substance that freezes at a lower temperature than water. This liquid substance is usually a mixture of water and a proprietary additive that prevents it from freezing solid, allowing the cube to remain flexible even when frozen.
The reusable ice cube works by absorbing heat from the surrounding liquid, cooling it down without diluting it. As the liquid inside the cube freezes, it expands, but the flexible material prevents it from bursting. Once the cube has thawed, it can be refrozen and reused multiple times, making it a convenient and eco-friendly alternative to traditional ice cubes.
What is the liquid inside reusable ice cubes?
The liquid inside reusable ice cubes is typically a mixture of water and a proprietary additive, such as a polymer or a glycol-based substance.
