Surface Tension
Surface tension is a physical property of liquids that causes the surface to behave like a stretched elastic membrane. This occurs because molecules at the surface experience a stronger attraction to each other than to the air above them, resulting in minimized surface area. This effect allows small objects, like a water strider insect, to float despite being denser than water. Surface tension plays a crucial role in various natural processes and phenomena, influencing everything from the formation of droplets to the behavior of bubbles.

Surface tension is a physical property of liquids that causes their surface to behave like a stretched elastic film. It arises because molecules at the surface of a liquid are attracted more to each other than to the air above, resulting in a cohesive force that minimizes the surface area. This is why small objects, like a needle or water striders, can sometimes float on water without sinking. Surface tension also plays a significant role in various phenomena, such as the shape of raindrops, the ability of some insects to walk on water, and is significant in many applications, including detergents and coatings.
