dry ice is the cold dense white mist produced by solid carbon dioxide in air, used for theatrical effects.
Get a cylinder of CO2 gas with a valve on it and a heavy, porous cloth bag. Using heavy gloves hold the bag over the nozzle of the CO2 cylinder and gradually open the valve. Dry Ice will collect in the cloth bag.
