When paper gets wet, however, those bonds are damaged and the fibers separate more easily. In turn, the paper becomes weak and tears.
How does the upside down water trick work?

Liquid water is not itself wet, but can make other solid materials wet. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material. Cohesive forces are also responsible for surface tension.
Is a fish wet or dry underwater?

Why do ducks easily swim on freshwater?
Ducks’ feathers help them float not just by repelling water, but by trapping air. Their feathers have tiny barbs, which allow them to latch together like Velcro. This creates a balloon-like effect, trapping air between the feathers and the skin, and those air bubbles add to the duck’s natural buoyancy.
How long can Ducks stay in water?
