How do they get cold? Should I wet them and freeze them?

Yes. Put it in a sink and let it sit in cold water. It will puff up. I then put it in the freezer. I did find that one of them started leaking in my freezer bag.

If you soak them in warm water instead of cold they will absorb the water very quickly, less than a minute.

Yes. Soak them in the sink for about 20 minutes, then freeze them. I keep mine in ziplock bags because they do leak a little as they thaw. They stay pretty cold though.

Soak them in water for 20 to 30 minutes. Then freeze them until frozen solid. They work wonderfully. I use them for physical therapy, since they retain the cold for 4-5 hours.

Yes you do wet them and then freeze them. They stay frozen a super long time if you use them with one of the Polar Bear Coolers

yes- wet them, THEN freeze - no directions accompany them, so i figured that out by trial and error.

I put mine in the bath tub with a few inches of water and let them soak for half an hour or so and then pop them into the freezer! It's that simple. I re-hydrate them from time to time as the part that freezes seems to get smaller over time. These things really keep things items quite cold. I put one on the bottom of my lunch bag and one on top of my food as well. I have no regrets with this purchase!!!

I refrigerate them in the bag they came in. Take out what you need and let them warm before use. I dip them in clonex solution before use

I was them in the machine in cold water and then allow them to dry naturally. Seems to work quite well!

I wouldn't recommend freezing them. They are great bottles but freezing plastic is not a good idea.

If you can purchase an insulated box from them. I ordered mine when the weather was warmer and they were sent open to the air in a net bag. Worked fine then but I am afraid they would freeze now. It took about 5 days to receive.

They will get cold but will not start to freeze. It also depends on your cooler. Usually mine lasts for an hour but I have multiple sclerosis and put off alot of heat. If it's hot outside they will melt alot faster too. Your best way would be to freeze all that you have, and put them in the cooler and use them as needed.

they take about an hour to re freeze, however they dont stay cold for very long.

I keep them in my freezer. They usually stay cold for two days in a cooler. I also using them when I need to put ice on my knee or on my back.

What I did when I first gotten them was plug them in out of their bowls. The second thing I did was wrap their bowls in a towel or a small blanket and that helped with heating and maintaining the heat of the water. With a cold house that method really helped. I didn't have to heat a whole room, just them.

They don't require freezing...they're dry. I'd be afraid of them cracking into pieces. I store the unused in a large Ziploc. They don't go bad. Place 1 flat in lukewarm water for 10-15 seconds and as you arrange your filling for rolling, it gets more and more pliable. They're quite lovely.

put the mold in the freezer for 5-10mins and they should pop out with no problem.They will appear to have a fine wet look from the cold. Just place them insideof a new paper bag for an hour and they will be good to go.

They are not cold at all. In fact I don't think you are even supposed to put them in the freezer. They are for decorative purposes only:)

Because mine never froze, they would float. Even the few I had that would freeze floated. Hope that helps.

Not sure. I did freeze mine but haven't defrosted them yet. I hope they taste alright. I will post when I do defrost them though. They are the same kind that Whole foods and Trader Joe's sell in small containers. They are not that mushy and they were the hit of my party. Everyone loved them!!!

I live in south Texas so it freezes very little. I would drain them for winter living here or up north. The water in them would expand if frozen and could cause damage. I leave mine outside all the time and would if I lived back in Michigan also. These are very sturdy.

I have not tried to put them in the freezer. I am writing this to you as I sit next to the pile of used ones that need to be heated again to make them liquid, they become solid after use. That pile has been there for several weeks. Really not worth the money. I would not buy these again, they are a total pain. If after you heat them if there is even one crystal left, this can be very hard to see, they will just reheat when you take them out of the hot water and you are stuck heating them again to reset. They do not stay warm for nearly long enough to make them worth it. I would strongly urge you to skip these and go with an old fashioned water bottle. Sometimes an oldie is a goodie.

They will turn solid when frozen and slowly thaw. If you keep them in a good insulated cooler they should stay frozen for the flight
