How Colloids Actually Works

Think of it like a milkshake – blending together two liquids to create a smooth, consistent result. Colloids can be solid, liquid, or gas-like, making them a versatile tool for scientists and innovators. When oil droplets mix with water, for instance, they form a colloid that can be used in everything from sunscreen to cleaning products.
