How is dry ice made?
Dry ice, which is solid carbon dioxide, is made by liquefying carbon dioxide into colorless liquid under the pressure of 6250.5498 kPa, and then rapidly solidifying under low pressure. Carbon dioxide is invisible. It's not smoke, it's fog. When carbon dioxide changes from solid to gas, it absorbs a lot of heat, which makes the temperature of the surrounding air drop rapidly, and the air temperature drops accordingly. Its solubility in water vapor becomes smaller. When water vapor liquefies, it releases heat and becomes small water droplets, which is fog.

The temperature of dry ice is much lower than that of water, so it is equivalent to heating dry ice, which absorbs heat and sublimates, reducing the temperature of water and even freezing it. Stages, theaters, movies, weddings, celebrations, parties, etc. Will use dry ice to create the effect of a sea of clouds. Adding dry ice to seafood dishes made in restaurants can create a white smoke landscape and improve the banquet level.
