Rest your wrist to give it time to heal. You may find that, depending on the severity of the sprain, immobilization through a soft cast is necessary. If your sprain is the result of a sports injury, you should stop playing the sport immediately, at least for a few weeks while your wrist heals.
Water also has a high level of surface tension. This means that the molecules on the surface of the water are not surrounded by similar molecules on all sides, so they're being pulled only by cohesion from other molecules deep inside. These molecules cohere to each other strongly but adhere to the other medium weakly.
This is called adhesion because the attraction is to a different substance. In all systems within which water interacts with another surface, both adhesion and cohesion are factors. When cohesion is more of a factor, the water forms spherical droplets; when adhesion is more of a factor, we get sheets of water. water drop on oiled plastic wrap (cohesion of water and only a little adhesion of water to plastic)
