To put it in plain english.
pure ice is 9% lighter than water
I like fisher's explanation about why this is so

It is well understood why ice is less dense than water (a 104 degree bond angle in the crystalline structure of ice that means the same mass takes up more volume.)When water molecules freeze, they form up into a crystalline lattice kind of structure, which increases the space between the individual molecules, as compared to the space between them when in a liquid state, thus lowering density. Compare this to all (I believe) other liquids which become denser when they freeze/solidify.
Density of ice = 57.25 lb/cu. ft.
Density of Water = 64.43 lb/cu. ft
The difference in density would be 64.43-57.25...or 7.18 lbs/cu. ft.
So...who can explain why water, still in a liquid state, begins expanding at 35 degrees?
water is less dense in it's solid state than it is in it's liquid state.
