ELI5: What is emulsification and how does it work?
gpt
An emulsion is when two liquids that don’t mix or dissolve in each other (immiscible) are put together and then mechanically mixed so that even though they remain separate at a small level, they’re still pretty well mixed.

The most familiar example is probably oil and water. Oil will float on top, and stirring a little doesn’t change it. If you stir and shake a lot, the two liquids form droplets that can be all randomly jumbled together.
