Why can water striders walk across the surface of water without falling through?
They are light enough so they don't break the hydrogen bonds holding the water molecules together
The insects actually use their wings to hover slightly above the water’s surface
The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
