Back in 2016, when my sister and I made our first visit to DV, I was in charge of food. I wasn't sure that plain ice would keep stuff cold long enough so I bought some dry ice for our cooler. I can't remember now how well it did keeping the temperature down (I think it did okay) but what I will always remember is the funny metallic tang to the taste of our grapes, avocado, and other fresh foods. We initially thought the grapes had just gone bad until we found that taste in other snacks. Later on I noticed that if things were left out of the cooler, they eventually lost the weird taste.
My question is whether anyone else has experience and advice on using dry ice. Specifically I'm wondering whether putting it in a zip lock (carefully) would contain the gas, or if I kept it in water, would it freeze a shell around itself?
This has come up because, mirabile dictu, after years of offering to take family members camping in DV, someone has finally taken me up on it. My high school aged nephew will join me for a week. I'm excited because he enjoys outdoor adventures such as Boundary Waters, so I think he will have a good time. Then I remembered how much food that boy can put away; I'm going to need more than the small amounts I get by on. Wish me luck!
