Surface Tension has significant impacts on the survival as well as the processes needed for day to day existence of living beings. For example, insects such as water striders depend on the surface tension of water to move around and capture food. Most household detergents contain Sodium Docedyl Sulfate (SDS) which reduces the surface tension of water. If local water reachesa specific concentration of detergent, water striders will break the surface tension and sink. Surface tension is also essential for the transfer of energy from wind to water to create waves. Waves are necessary for rapid oxygen diffusion in lakes and seas. Understanding surface tension and what affects it is vitally important for researchers and engineers alike because new solutions for treating water have to maintain water's delicate and complex balance.
