This past July I stocked my outdoor mini fridge with all types of beverages, water, juice, beer, etc... After a few days I noticed that one of the bottled waters was frozen. Thinking it was the placement in the fridge, I moved it around. I noticed that it still remained frozen, yet nothing else in the fridge was frozen. As the months passed and eventually just about everything was consumed, that one bottle has stayed frozen this entire time. A few days ago, I moved the fridge into the basement. Tonight I took the temperature of the last remaining unfrozen bottled water in there, it was 36 degrees. Same temp for an apple juice that was also in there. What gives, how is this water still frozen?
