Liquid rises in and out of cappilarry to compansate pressure difference.
Rise of a liquid in capillary is indirectly proportional to radius of tube so liquid goes higher in a narrow tube.
The 'capillary effect'. See the link.

When water rises from the soil by the roots of the plant. The capillary effect is done in a lot of things. Example: When water is obsorbed by the paper up the toilet paper tube.
That effect is called adhesive or capillary action. It occurs when the liquid molecules are attracted to the surface of the container, causing them to be pulled up and stick to the side of the container as they flow.
One effect that adhesion produces is the ability of water to be transported through plants against gravity. This is due to the cohesive and adhesive properties of water molecules, allowing them to stick together and to the walls of plant vessels, helping to pull water up from the roots to the leaves.
Little air pockets or air cavities in the towel hold the water until squeezed out. All the little microfibers in them make them super strong and absorbent also the sponge pockets make them absorbent.
Due to combination of polarization and capillary effect
Adhesion causes the liquid to rise slightly in the straw, creating a meniscus. This phenomenon occurs due to the attractive forces between the liquid molecules and the straw surface, which causes the liquid to climb up the straw slightly before reaching equilibrium.
A combination of adhesive and cohesive forces accounts for capillary action, which is the tendency of water to move through narrow tube's, and even against gravity.
Due to surface tension of water the component T cos @ acting all along the circumference of the capillary tube 2 pi r would get added as 2 pi r T cos@. Here @ is the angle of contact of water with the material of the tube ie glass. Hence this uplifts the water to a height till its weight gets balanced by 2 pi r T cos@.
The Donnan effect refers to the uneven distribution of ions across a semipermeable membrane, affecting osmotic pressure by causing water to move across the membrane. In capillaries, this can impact fluid balance between blood and tissues. The Donnan effect can also influence pH by affecting the distribution of charged molecules, such as ions or proteins, leading to changes in the local pH levels.
