eli5 Can someone tell me what makes water wet?


Eli5 I’ve always wondered what makes water wet when it’s made up of h2o molecules.

Water isn’t really “wet” in and of itself. Rather, water can *make other things wet*, which in turn means that its surface tension breaks easily and it will coat other materials, sticking to them.

Some liquids don’t wet materials when placed on them- mercury, for example. Or oils on a waxy surface, etc.

The term “wet” basically just means that liquid can break its surface tension and coat a material, and it applies more to the material than the liquid.

But since the most common liquid we deal with as humans in our day-to-day lives by far is water and water-based liquids, the term has become very closely associated with the liquid itself instead of its action.
