Small insects can walk across the surface of calm water. Their feet push the surface of the water down slightly, somewhat like a person walking across a trampoline, but they do not break the surface. What is the best explanation for why this happens?
The insects are light enough so that they do not break the hydrogen bonds holding the water molecules together
The insects actually use their wings to hover slightly above the water's surface and they only skim it with their feet
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
