To travel with oar-like rear-legs over the water's surface without sinking is a way in which water boatmen use surface tension. Surface tension reflects the elastic film-like, tightly-packed, uppermost watery level which forms from a series of positive hydrogen sides of one molecule attracting negative oxygen sides of another and which thereby lets heavier objects float and move.
