Water is a polar molecule and thus when a glass tube or any other tube with polar molecules is placed in water, the water molecules will attract the sides of the tube and overcome gravity. The property of water to attract the sides of the tube is called adhesion and the reason water isn't only on the sides but in the middle too is because of cohesion. Cohesion is water's ability to attract and hydrogen bond with itself so the water molecules on the sides of the tube attract other water molecules creating a network that reaches all the way across the tube.
Capillary action is also essential for the drainage of constantly produced tear fluid from the eye. Paper towels absorb liquid through capillary action. Chemists utilize capillary action in thin layer chromatography, in which a solvent moves vertically up a plate via capillary action. Dissolved solutes travel with the solvent at various speeds depending on their polarity. With some pairs of materials, such as mercury and glass, the interatomic forces within the liquid exceed those between the solid and the liquid, so a convex meniscus forms and capillary action works in reverse.
A fountain pen works on the principle of capillary action, where ink is drawn out through a feed and into the nib by the combination of gravity and the surface tension of the liquid. This allows for a controlled flow of ink onto the paper when the pen is in use.
Capillary action will pull water up the stem to the flower and into the petals.
The adhesive intermolecular forces between the substance rising (the one experiencing capillary action) and the container (typically a capillary).
A paper towel absorbing liquid is an example of capillary action.
Water has the greatest capillary action due to its strong hydrogen bonding and cohesive properties, allowing it to easily move through narrow spaces and against gravity. Other liquids with high capillary action include mercury and ethanol.

Capillary action and the nature of nutrients and water underground are reasons why 100 meter trees can uptake water. Capillary action is the reverse of gravity, which keeps things earth born and grounded. Gravity works downward whereas capillary action works upward.Additionally, nutrients and water underground aren't comfortable with their minimal or no presence elsewhere. So nutrients and water cooperate in moving out of the soil where they're present, and into tree roots and up tree trunks where they're not.
Water uses capillary action to "climb" up plant vessels through cohesion and adhesion, which allows the water to be transported throughout the plant.
Water is transferred from the roots to the leaves through the stem by capillary action.
