Dry ice will typically keep things frozen for 24 to 48 hours in a cooler, under ideal conditions. The precise duration depends on several factors, such as the amount of dry ice used, the cooler's insulation quality, and external temperatures. For optimal results, use 5-10 pounds of dry ice for a 24-hour period in a standard 25-quart cooler, and double the amount for a 48-hour period. Always handle dry ice with gloves and ensure your cooler is partially vented to release gas safely.
