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: -The Science Behind the Walking Water Experiment With a little bit of magic called capillary action. Essentially, the adhesive force between the paper towel and the water are more powerful than the cohesive force inside the water itself. This results in the paper towel pulling the water up.
Detailed explanation-3: -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.
