Dry ice is most commonly used to keep things cold. It is often used in food storage, to keep ice cream or other frozen desserts from melting.
It can also be used to keep meat or fish fresh during transportation. Dry ice can be bought at most Safeway stores for $1.
To use dry ice, place it in a cooler with the food or drinks you want to keep cold. Make sure the lid of the cooler is tightly sealed so that the cold air doesn’t escape.
Check on the food periodically to make sure it is still cold. When you’re done using the dry ice, make sure to dispose of it properly. Do not put it in the trash can as it can cause problems for the garbage collectors.
