With a little planning and a few blocks of dry ice, you can bring your favorite frozen foods just about anywhere – even on a summer camping trip.
But how long will that dry ice last?
As you might know, dry ice (frozen carbon dioxide, the same gas that we breathe) does an amazing job at not just keeping food cold, but actually keeping it frozen – and if it is packed the right way, it will last a surprisingly long time.
How long dry ice lasts depends primarily on two factors: how it is stored and the size of the brick. The following table for how long dry ice lasts is based on an average five-pound brick of dry ice that remains whole (not broken into pieces):
To put it another way, if stored properly (that is, in an insulated cooler…see below), dry ice sublimates (turns from solid form to gas form) at a rate of about 5-10 pounds every 24 hours. That means that if you need about 15 pounds of dry ice for the next day, you need to buy 20-25 pounds the day before. This is why it’s important to buy your dry ice as close as possible to the day you’re going to need it. Plan accordingly!
