Has anyone ever put it in their fridge and/or freezer. I know it's super cold and I don't want to damage the interior or mess anything else up. I have a yeti cooler and it states it is dry ice safe, which leads me to believe that somethings are not! So, anyone ever tried this?
I do it all the time. Especially when we are camping without access to shore power.
I wrap some dry ice slabs in a thick layer of old newspapers and put one in the fridge and one in the freezer. It usually lasts a few days and reduces the amount of propane used to keep the fridge cold.
I bring a large cooler of dry ice and as it evaporates in the fridge, I replace it from the cooler. the large amount in the cooler helps keep it solid for longer.
If you want something to stay frozen, put right on top of the newspaper wrap. If you want to just be cold, leave some space between the wrap and the item - Dry ice will freeze it it short order!
It helps that I have a pretty endless free supply of the stuff from my work...
