Well, to begin, let's actually define what surface tension is. So surface tension basically means that the molecules found on the surface of the liquid remain on the surface and they're able to bond very well with adjacent liquid molecules. In the case of water, it's adjacent water molecules. And so when we try to apply a force onto the surface of that liquid, because of these relatively strong intermolecular bonds, and because the molecules on the surface don't actually move too much, those molecules are able to actually stand their ground when a force is applied onto that surface. So surface tension means that it is relatively difficult to break the bonds that exist on the surface of that liquid. And this implies that the bonds on the surface of our water are strong and the water molecules on the surface don't actually move too much and so they can stand their ground when a force is applied on them.
