> Water is harder to store in the winter since it will freeze and burst containers if full In my experience, filling a PET bottle to the brim with tap water and freezing it is fine. The bottle won’t burst, but, I guess, be stretched a bit. Some water will be forced out when you open it, but that’s all. I use this on hot summer days. Freeze water overnight, take it with you, and you’ll still have cool water in the afternoon. Warning: I haven’t tried this in outside temperatures. Those can get a lot lower than you garden variety freezer unit inside a fridge.
