This is a follow up to my "where to find dry ice for camping" video. The dry ice held up till 3 1/2 days after we picked up 20lbs of dry ice from a local Safeway supermarket. Also remember that the cooler was stored in the shade from our tent in an average daily hi temperature of 90100'F and average daily low of 6570'F. The cooler we used was an igloo 50qt 5day cooler. We may be trying this experiment again in early September when we go camping again and the average temperatures will be 15'F lower. Hopefully the temperature drop has an effect on the longevity of the dry ice in the cooler.
