The 'capillary effect'. See the link.

Hydrogen Bonding
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.
You should always open the window when you are soldering because you can breath in toxic fumes which could effect you health!
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.
Juice travels up a paper towel through a process called capillary action. This occurs when the cohesion between water molecules in the juice is stronger than the adhesion between the water molecules and the paper towel fibers, causing the juice to move against gravity and spread across the towel.
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.
