Dry ice is the solid form of carbon dioxide. Unlike regular ice, it does not melt into water. Instead, it sublimates, turning directly from a solid into gas. This creates the thick, ghostly fog, that can be seem in many horror movies, theatrical productions, and hunted house attractions. With a temperature of -78 °C (-109 °F), it is much colder than regular ice and ideal for both chilling and thrilling.

• Use 4 litres (1 gallon) of water per 900 g (2 lb) of dry ice.
• Use a deep bowl at least three times the height of the dry ice block.
• Use a small fan to extend the fog’s reach.
• Refresh the water regularly to maintain fog quality.

The amount depends on your setup, the size of the room, its temperature and how long you want the effect to last. Here is a rule of thumb:

1. Use an insulated cooler with ventilation. A Styrofoam chest with a loose-fitting lid is ideal.
2. Line the inside of your cooler with cardboard, polystyrene foam, or a blanket to protect it from damage.
3. Never store dry ice in a sealed container or in your freezer.
