> They proposed that instead of the Van der Waals forces that normally draw water molecules gently together, polywater was composed of molecules locked in place by stronger chemical bonds, somehow catalyzed by the quartz capillary tubes.

Aren't water molecules held together by relatively strong Hydrogen bonds? And if there are stronger bonds in polywater, what are they, then, covalent bonds?

Actually a single water molecule is held together by covalent bonds between the O and two H's, and hydrogen bonds (not Van der Waals) are the intermolecular forces responsible for the properties like surface tension and high boiling point.
