The document discusses the surface tension of liquids. Surface tension allows insects like water striders to walk on water and causes water to form spherical droplets on surfaces like taro leaves. Surface tension decreases with increased temperature or impurities on the surface or dissolved in the liquid. Highly soluble substances increase surface tension while sparingly soluble substances decrease it.
