When we put an empty capillary tube in a water container, the water goes up a little bit by itself until the surface tension (ST) force is equal to its weight .This shows that unlike friction, this ST force acts individually .
So if we take out the tube out of the container, and drain a little water (in which case there's less water in it), the ST force would be more than the weight of water. So why doesn't it go up continuously in the tube?
