How organism like 'pond skaters' can 'walk' on water?

It's called cohesion. The water molecules are polar with the O being slightly negative and H being slightly positive. The polar molecules attract to one another creating cohesion. Since the organisms are so small they don't break the surface tension and can "walk" on water!

If the question which you're asking is "How can the insect everyday as a pond skater seem to stroll on water?" then the respond is easy. floor section vs floor rigidity and the minimum displacement of water. Water in that's stagnant state keeps a floor rigidity, plenty comparable to in case you fill a pitcher of water to very suited and then slightly greater water remains seen above the glass. this may well be a results of floor rigidity. The pond skater makes use of this to its benefit because it "skates" around the exterior of the water. Displacing its weight by skill of frivolously dispensing it over six legs and a bigger than itself "floor section".

Those insects distribute their weight just the right way, so that the surface tension of water is strong enough to hold them in that position. Notice how they always "walk" with their legs outspread in each direction.

The surface tension of water is really great.
