One may also ask, can you keep dry ice in a freezer?
Dry ice should be stored inside an insulatedcontainer. The storage unit, however, should not be completelyairtight. The carbon dioxide gas can cause a container toexpand if it is airtight, and it could even cause thecontainer to explode. Also, make sure to not store dry icein a regular freezer in a refrigerator.
When placed in a cooler, dry ice can last from 18to 24 hours. Dry ice lasts anywhere from 3 to 5 hours whenleft outside. Placed in liquid, dry ice will lastfrom 15 to 45 minutes.
