David, There is a nice page I found explaining Bose-Einstein Condensates that you might be interested in from the Ketterle Group at MIT. The first point about Bose-Einstein Condensates is that they are a phase of weakly interacting gases so they cannot occur in ice, a solid. However, if the pressure is low enough, water can exsist as a gas to very low temperatures; could the gas form a Bose-Einstein Condensate? Probably not. Water, even as a gas, is not weakly interacting. It is an electrically polar molecule, and can therefore interact with other water molecules over large distances. Also, if you refer to the page I mentioned earlier, you will find that the cooling methods used in creating Bose-Einstein Condensates are suited only to single atom gases, so it would be difficult to cool water to a point where creation of the condensate is physically possible.
