Dry ice is denser than water, it sinks, not float. Check the wikipedia links below, and notice the densities of ice, water, and dry ice. Ice is 917 kg/m^3, water is 1000 kg/m^3, and dry ice is 1600 kg/m^3, the heaviest. Also check dryiceinfo.com about using dry ice in beverages.

Dry ice is much denser than water ice. Therefore, dry ice actually sinks in water. The trick is, because dry ice is so cold, and sublimates directly into carbon dioxide gas upon heating, dropping dry ice into water causes a lot of bubbling.
Water ice has a density of .917 g/cubic centimeter, dry ice is about 1.56 g/cubic centimeter.
