I have bought dry ice, which has many uses: food, seafood, fruits and vegetables, poultry meat, cold drinks, refrigeration, sterilization, preservation and transportation; High-end dishes, stage, wedding, film and television fog; Medicine, artificial rainfall, fire fighting, non-destructive and pollution-free gasification cleaning, etc. Go to Liuzhou No.1 Gas Company in Guangxi and send it by express. It will arrive in a few hours! But it volatilizes quickly, so it's best to buy dry ice and reuse it, and the effect is very good.
