Product Information

Once frozen, simply add a little water to the top to begin the thawing process and screw in the cap. You can keep drinks cool and when the ice melts the water will just run out like it would when you do laundry. This would ensure there is enough room for expansion during freezing without worrying the lid will pop off! So I thought maybe the tip I read to lay them on their side helps prevent that, but it would then flow out without the cap, and with the cap on the cap would freeze shut. As we’ve discussed glass water bottles are generally safe for freezing however, I’ve included 5 precautionary points below to help you prevent your water bottle from getting damaged.

Half-filling before freezing and then topping up worked well for me - drinkable iced water from that start and still icy after a couple of hours. Instead, the best way to prep your ice water is to fill it up just under halfway and then place it on its side. Surely, as water expands when freezing, the bottle may not be able to contain it all, so what do we have to do? I now fill mine about 1/3 full and then tilt it at an angle in the door of the freezer, I either leave the top off or leave it loose, this way when it expands it has room to expand up and out and not split the sides. And if you weren’t already sticking a water bottle in the freezer overnight, consider yourself doubly enlightened.

Remember to choose a freezer-safe bottle, leave room for expansion, and thaw gradually to ensure the longevity of your glass water bottle. Interestingly, these claims were later debunked, and these institutions do not support these claims. Stories have long been circulating about the risk of freezing water in plastic bottles and increasing the risk of cancer.

The plastic used for bottled water is polyethylene terephthalate (PET), which the FDA has deemed safe for food packaging under normal use. Someone I know suggested that I freeze the water bottles the night before, so that the water will be cold all day. Summer is now well and truly upon us and so as the days get warmer, I’m starting to think about how I can keep my drinks cool as I travel to work. We asked what some of you are doing to prepare for a potential storm and a few really unique and helpful ideas came up. I have a Camelbak Podium Ice which is the same physical size as a Podium Big Chill but only holds 21oz due to the extra insulation.Glass water bottles are considered a better option when it comes to water storage as they are less likely to leach chemicals into the water.
