Two years ago I brought Dry Ice, and it kept the ice cream until Thursday.
This year I'm taking the next step.
I have been gifted a large chest freezer thru my local Freecycle list, and I own a Honda EU3000 (nice and quiet) generator. We have established that the generator has more than enough power to run the freezer.
I have even bought a cute little "remote" thermometer to monitor the temperature inside the freezer.
Now the question:
If I put new unopened cases of bottled water -- one gallon and/or 2 1/2 gallon jugs -- in the freezer a week before I head up there, what are the odds that those jugs will be intact when we take them out and let them melt?
We would use the frozen jugs to keep food and drink cold, and finally drink (or wash with) the water.
I have three weeks to test it, but maybe some of you have tried.
I do know not to try this with metal cans and glass bottles.
When I freeze a couple of gallons in my kitchen refrigerator, the expansion is quite alarming. I freeze bottles that are less than full, and leave the cap loose until they are frozen. Will I need to pour off some of the water in all my new jugs?
