Hydrogen bonds bind water molecules to each other, giving the droplet its characteristic shape. But they're easily broken. Researchers from two collaborating US universities recently discovered a form of hydrogen bond so strong it's comparable to the covalent bonds binding hydrogen and oxygen together into water molecules within the droplet. This newly discovered bond hasn't been observed before because it is a very brief intermediate phenomenon taking place during a chemical reaction. The relevant paper was published in the journal "Science" yesterday.
