Walmart sells dry ice. However, it is not available in all locations, so the Walmart website should be consulted to determine the availability of dry ice.
Dry ice should not be handled with bare hands. It has a surface temperature of -109.3 degrees Fahrenheit, which can damage the skin. It should also be used in a well-ventilated area to minimize the risk of carbon dioxide poisoning.
Dry ice keeps things cold when there is no power for refrigeration, such as during transportation, shipping, camping or power outages. It is less messy than regular ice because it sublimates into carbon dioxide gas rather than melting into a liquid.
