1, dry ice should be stored in a special freezer, so that dry ice can be stored for 5- 10 days. It can also be kept in a dry thermos bottle for only one day and one night. It can also be stored in a special storage box. Generally, there is no special storage box at home, so you can put it in an ordinary foam box.

2. Dry ice should not be exposed in the refrigerator or freezer, which may easily cause the refrigerator to explode. Dry ice cannot be mixed with liquid.
