Why can bugs stand on water? What is surface tension?
Certain things can float on water because of a property of liquids called "surface tension." Surface tension causes the surface of liquids to act like a thin, invisible membrane. Water molecules are attracted to each other. This gives water its high surface tension. The high surface tension of water allows items that are more dense than water, such as liquid dish soap, to be suspended on its suface.
