Solid Carbon Dioxide - CO2, is used in a number of different applications. It can be used in laboratories for mechanical cooling and is commonly used to preserve and transport food. Dry ice is sometimes used to make ice cream and even removing warts. Plumbers use dry ice to freeze pipes and in the theatrical world it is used for smoke effects with a fog machine. It can be used to kill underground rodents and insects by freezing and starving animals or insects of oxygen. Mosguitoes are attracted to the carbon dioxide that humans breath out so in some hot countries people holding Bar-B-Q's often place an amount of dry ice away from their party area to lead mosquitoes away from their guests.
