12 pack Coke + trunk of car + cold night = oops.

I was loading up some stuff to bring to school and found a nice surprise in the back of my car.  A 12 pack of diet Coke I left back there from before the break.  Well, last night it got down to 7°F (-14°C) and who knows how cold it was the couple nights before, which isn’t good for cans of soda in the back of your car.  Six of them survived and are now cooling off my fridge.  Fortunately it was cold enough that even though it ripped the top right off one of the cans, the other six cans that exploded were frozen enough that the soda stayed in the box, no mess in the car.
