Nope, corn syrup is also higher density than water.

In fact, normal ice does float on normal root beer (I worked for awhile as a
soda jerk many years ago).  So I'm also at a loss to explain what Steve saw;
unless perhaps the ice was stuck to the glass and only came free after the
level had dropped.  

Used to be that A&W would store their glass mugs in the freezer, so when
they added root beer, the cold mug would actually freeze water out of the
root beer onto the glass.  But I thought they quit doing that a long time
ago (shortly before I stopped buying root beer there).
