Ice is less dense than water

remove all the air from water by
boiling it. let it cool. freeze it. you'll
get ice that is clear...like you get at
some ice machines and restaurants.
it still floats. try it. it is neat if you want
to get some clear ice.
because of the uniquely strong hydrogen
bonding in water, liquid water is actually
more dense than the solid crystalline water, ice.
water is special this way. life on earth would
be very different if entire ponds froze each winter
instead of being insulated from the outside by
a layer of ice floating at the top. it is a very cool
and important phenomenon.
liquid water reaches a maximum density at around 4 C and
then expands slightly as it nears the freezing point
(at atmospheric pressure) of 0 C.

Ice is less dense than water because of the unique structure of H2O (2 in subscript). In liquid form, the hydrogen bonds between adjacent H2O molecules are constantly forming and reforming, which means the space in between the molecules is constantly being filled by different molecules as movement occurs. However, when water freezes, the H2O molecules are stuck in a lattice structure, and the spaces between the molecules are not constantly being filled. This results in what the previous two answers have said - ice having a lower density then water.
This is a Chem and not a Physics answer, by the way. XD

Water molecules have positive and negative charges at their ends, which align into a crystalline structure as it freezes, taking a slightly larger volume to do so, hence ice is less dense and so floats on water.

How many layers of why?
Ice is less dense than liquid water close to the same temperature.
Why is ice less dense than cold water?
The crystal structure of ice holds the atoms farther apart than the random order of cold liquid water.
Why?
I don't know.

similar volume of ice and water do no longer WEIGH an similar. A a million liter field of ice weighs decrease than a a million liter field of liquid water, and the lighter cloth floats to the right.

The hydrogen bonds in water cause it to actually expand in volume when it freezes. That makes it less dense than liquid water, thus boyant.
I'm not sure, but I think water is the only substance that gets less dense when it goes from liquid to solid.

The molecules in water are random, when they crystallize into ice they expand, making the ice less dense than the water.

becaaaaaause ice is less dense than water where density = mass/volume

ice has air in it
