Detailed explanation-1: -Paper towels are made of many small fibers that have gaps in between them. Water gets pulled into these gaps by capillary action-the same phenomenon that allows trees to suck water out of the ground.

Detailed explanation-2: -Capillary action is all around us every day If you dip a paper towel in water, you will see it “magically” climb up the towel, appearing to ignore gravity. You are seeing capillary action in action, and “climbing up” is about right-the water molecules climb up the towel and drag other water molecules along.

Detailed explanation-3: -Capillary action is when a liquid, like water, moves up something solid, like a tube or into a material with a lot of small holes. Capillary action works against gravity because of three special forces called cohesion, adhesion and surface tension.

Detailed explanation-4: -The water is able to move up and through the paper towel because of a process called capillary action. The water travels up the tiny gaps in the fibers of the paper towel. The water molecules are cohesive so they stay close to each other, but they also bind to the paper towel through a process called adhesion.
