We’ve written a lot about the many uses of dry ice over the course of this blog, but there may be one question still remaining before you commit to trying dry ice for any of those purposes. How long does dry ice last? We hope to answer that question and more in this week’s post, so keep on reading!
How Long Does Dry Ice Last?
Well, unfortunately there is no end all be all answer to this question, as it depends on the size of the block and the conditions in which it’s being kept. What we can tell you, however, is that dry ice sublimates at a rate of about 5 to 10 pounds per day when kept in a typical ice chest. This rate accelerates to 5-10 pounds per 3-5 hours outside, and when it’s placed in liquid, the same amount can disappear as quickly as 15-45 minutes. Using this logic, if you need enough dry ice to make it through an event tomorrow, you’ll need about 20 pounds to last you two days (if stored properly). Makes sense? Good.
How to Make Dry Ice Last Longer
We touched on it above, but proper storage is the biggest key to prolonging the life of your dry ice. The better a cooler you can provide and the colder of a location you can keep that cooler, the better. Just make sure that the cooler isn’t sealed tight and that the place you’re keeping the cooler is well-ventilated. Those are all things we learned way back in Dry Ice Safety 101. You can also wrap the dry ice block in plenty of layers of newspaper (carefully, of course), and the newspaper will act as a surprisingly effective insulator. Going another step further, keep some regular water ice alongside your dry ice and both will last even longer!
