Sometimes I only have 10-15 minutes and I have a water bottle out, but it's near room temperature. I need it to be near freezing, but I don't have time to do anything.
Usually I will just put it in the freezer until I have to leave, but that usually doesn't do much. Is there any way that I can get a regular plastic water bottle near freezing temperature (or at least feel like it) in 10 to 15 minutes?
It would only have to be one water bottle at a time, and it would be great it the hack could work for Gatorade bottles too. The water must stay in the bottle (it's a hastle to get back in).
