What is the use of dry ice?

Dry Ice is frozen carbon dioxide, a normal part of our earth's atmosphere. ... Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3°F or -78.5°C. Dry Ice is widely used because it is simple to freeze and easy to handle using insulated gloves. read more

Dry ice is also useful for the de-gassing of flammable vapours from storage tanks — the sublimation of dry ice pellets inside an emptied and vented tank causes an outrush of CO 2 that carries with it the flammable vapours. read more

FOG VISUAL EFFECT – Dry ice when combined with hot tap water will produce and awe-inspiring display of bubbling water and thick voluminous fog. Use a pound of dry ice for every 4L of hot water for 5-10 minutes of maximum effect. Since dry ice retains a temperature of -78°C, the water will cool rapidly. read more

Lastly, opening the cooler as little as possible will prolong the lifespan of dry ice. read more
