I understand that water expands as it freezes.  What I don't understand is why 
when I fill up my plastic water bottle with tap water, put it in the freezer, 
and then take it out, the bottle has contracted?  I'm having a hard time 
understanding why my bottle seems to be sucked in, but yet the water inside has 
actually expanded in the freezing process.
