[Q] Does heavy water ice sink or float in regular water?

Blue ice, I have heard that some company seeks out this ice for hi end water. anywho here is some blue ice pics.

 

 

 

It would make a fantasitic ice sculture.. Where's my jack hammer :confused:

No need. Boil some water and make some ice cubes. The boiling will remove almost all of the gases from the water. The ice will float just like any other.

I read in a New Scientist "Last Word" column that this is not as easy as it sounds.

When I find it I will post it here.
