How long does dry ice last? The question of how long does dry ice lasts does depend somewhat on the purpose it is being used for. As a general rule, it will last for 18-24 hours in a cooler or ice chest, 3-5 hours outside and 15-45 minutes when reduced to a liquid form. If you are storing it in a cooler, make sure it is not an airtight one as when the ice melts, the gases could cause the cooler to burst!
