droplets

A droplet is a small drop of liquid that has separated from a larger amount. It's like a tiny bead of water or oil.

When we talk about droplets, we usually think about them as tiny amounts of something like rain or dew on a leaf. We might see droplets forming on the surface of a cup when it's been left outside in the cold. But droplets can also be used to describe small amounts of medicine that you need to take with a spoon. For example, if your doctor says to take two droplets of cough syrup three times a day, you'll know exactly how much to measure out. In science and chemistry, droplets are important because they're tiny units of measurement for liquids.
