Halloween Special FX

Dry Ice is perfect for creating eerie special FX for Halloween

What is Dry Ice Fog ?

Dry Ice when combined with hot tap water can produce vigorous bubbling water and voluminous flowing fog. For example, when adding 2 kg of Dry Ice in a 20 litres container of hot water, the greatest amount of fog will be produced 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. As the water cools, the fog becomes wispier.

Dry Ice makes fog because of its cold temperature, -78.5°C, immersed in hot water, creates a cloud of true water vapour fog. When the water gets colder than 10°C, the Dry Ice stops making fog, but continues to sublimate and bubble. The fog will last longer on a damp day than on a dry day.
