Capillary Action
Capillary action is when a liquid can flow into tight-spaces. It does not need the force of gravity, and many other forces. Capillary action is caused by a combination of cohesive forces of a liquid and the adhesive forces between a liquid and the slim-material. An easy example of Capillary action is leaving a paper towel on a spill, the liquid of the spill is spreading onto the paper towel. A similar reaction is when you insert food coloring in water and dip a paper towel in that water, and the colored-water will then climb the paper towel.

Adhesion is the combination of a molecule and another molecule; adhesion towards water is when water molecules are mixed with other molecules. Water loves sticking to its self but believe it or not, there are many chances that water would rather go into the state of Adhesion. Adhesion takes a huge step in Capillary Action which is the ability to flow into tight-spaces. Just like in class we dipped the paper towel in water and the water was climbing the paper towel (Capillary action). Water is also adhesive.
Capillary action is important to life:
Humans depend on Capillary action for blood circulation. When blood is flowed down it easy to say it’s because of oxygen but when blood flows up its because of Capillary action along with capillaries. The world cannot exist without gravity but can’t function without Capillary action. In soil water from the wet areas thanks to Capillary action is transported to dry areas. Capillary action even gives the world it’s weather changes.
