ELI5: How do liquids stay homogeneous and not have settling issues, such as Coke or milk?
gpt
It's the difference between dissolving and making a suspension, when something dissolves into a liquid it becomes part of the liquid, think sugar in water, no matter how long you leave it that sugar stays evenly divided over the liquid. A suspension is tiny particles hovering in a liquid. If you give it enough time it will settle.  Like the kind of apple juice that still has apple in it.
