Water's Polarity
Captions available
The idea
Water is a polar molecule, carrying a partial negative charge near its oxygen and a partial positive charge near each hydrogen.
In practice
That partial charge lets one water molecule hydrogen-bond to several neighbors at once, forming a loose, constantly shifting network.
Where people slip
Water's polarity, not its size or its abundance, is the property behind nearly every distinctive behavior water shows.
