Theatrical & Special Effects

Combine dry ice with heated water to produce vigorous bubbling water and flowing dry ice fog Special FX. Dry Ice makes fog because of its cold temperature, -78.5°C or -109.3°F.

When immersed in hot water, dry ice creates a cloud of true water vapor fog. As the water cools, the fog becomes wispier. When the water temperature drops to 10°C or 50°F, the Dry Ice stops making fog, but continues to sublimate and bubble.

Placing 2.3 kg of Dry Ice in 15 to 19 liters of hot water, will produce the greatest amount of fog in the first 5 to 10 minutes. There will be far less fog for the next 5 to 10 minutes as the water cools down and the volume of Dry Ice diminishes.

How to create a dry ice fog effect

For each 15-minute period of fog put 2.3 to 4.5 kgs of Dry Ice into 15 to 30 litres of hot water. This will create a substantial volume of fog based on the temperature of the water and the surface area of the dry ice. Hotter water will make more fog. Very hot water will add its own rising steam to the vapor cloud. If there is no steam the fog will flow down toward the ground and in the direction of any air movement. A small fan will help control the direction of the fog.

Smaller pieces of dry ice like pellets have more surface area and so produce a greater volume of fog. However, they will also cool the water down much faster that a solid block of dry ice. The result is more fog but for a shorter amount of time.

Keep the water heated with an electric skillet, or dedicated fog machine to produce fog for a longer time. Note that the dry ice will vigorously bubble the water and may splash out some water from the container. Place the container on a surface that will not be damaged by water. The water vapor fog will also dampen the area it flows across. Tiled or hard surfaces may become slippery if the fog effect is produced for a longer period of time.
