Would that they only did freeze when you open the container!  We have had all to many experiences of leaving cans (or boxes thereof) of diet soda pop in a car parked outside (or in ouir unheated garage) overnight during cold Colorado winters, and having them explode, showering ice all over the trunk or wherever!  Diet pop is (must be) more readily frozen than the sugared kind.  At least, with no sugar, there's no sticky residue when it melts.  But it's fun to shake a supercooled water bottle and watch it freeze.  Guess I've been afraid to do this with a clear bottle of pop!
