WebCohesion is the ability of water molecules to bind together; this experiment ties into cohesion because for the water to stay on the penny, they must bind together. Hypothesis: I believe that about 15 water droplets will fit onto a penny. A droplet of water is rather small and water droplets will bind together. WebCohesion is the molecular force between particles within a body or substance that acts to unite them. Cohesion is in easier terms the bubble on top of the water you are pouring or the skin.
