Those with a sense of history know that there have been many claims of new forms of water. Remember Polywater? I am waiting for someone else to confirm these results with other experiments.

Molecular weight of water is 18 gram/grammole. Most of the weight of water comes from oxygen which has molecular weight of 16 gram/grammole. Density is defined as weight of one cubic centimetre of ice. Most of the weight of ice comes from the oxygen of water ice.The one cubic centimetre of ice is composed of crystals. If the ice crystals becomes disordered for some reason or another ( I hope this has nothing to do with acid rain due to sulphur). Disordered means the crystals have a lot of defects. Defects are missing oxygen atoms in the crystal.So you have low density.
