What Makes Water Wet? The Science Behind It

Mon Aug 25 2025
Water is pretty cool. It does things that other liquids don't. But what makes it wet? It's all about how water molecules behave. They stick to each other and to other things. This is what scientists call cohesion and adhesion. Cohesion is when water molecules stick together. They form something called hydrogen bonds. These bonds make water act like it has a skin. That's why water forms droplets. It's also why some bugs can walk on water. The surface tension holds them up. Adhesion is when water sticks to other things. Some things are easy to wet. Glass is one example. Water spreads out on glass. But other things, like Teflon, are hard to wet. Water just sits on top in droplets. It's like the water doesn't want to stick to it. So, is water wet? It depends on what you mean by wet. If wet means making something damp, then yes, water can do that. But if wet means something else, it's not so clear. Scientists still argue about it. Water's behavior is important. It affects how things work in nature and in our daily lives. From how plants drink water to how we clean our dishes, water's stickiness matters.
