Dry ice bucket is a device for storing dry ice, which is very convenient to carry. The traditional dry ice storage device is bulky and inconvenient in some emergencies, so the dry ice bucket came into being. Dry ice stored in a dry ice bucket is solid carbon dioxide. Because the temperature of dry ice is very low, the temperature is -78.5 degrees Celsius, so it is often used to keep objects in a frozen or low temperature state. Dry ice bucket can ensure that dry ice can quickly freeze objects and reduce the temperature, which has been widely used. Dry ice does not change from solid to liquid when it is dissolved, but sublimates directly from solid to gas, so its melting will not produce any water or liquid, which is why we call it "dry ice".
