My vote/guess.  The thickness of the root beer, which allows a nice head 
to form, keeps the CO2 bubbles suspended lowering the density of the 
liquid.  Don't know if its confirmed, but gas released from sea floor 
hydrates are supposed to sink boats.

You might be able to reproduce this at home using a really stout ale.
