why not just use styrofoam that already floats, doesnt need the top glued

Oh, not really. Over many years the UV will break it down some, but we're
talking years, not months. You can always put a coating of latex paint on
it. Entire companies have been in the business of supplying the molded foam
for use in mooring buoys, lobster markers, etc. Not to mention pool
accessories, floating chairs, surf boards, etc.
