DANCING IN THE FOG

At concerts, festivals and stage shows, thick fog provides for goosebump moments. It often comes from carbon dioxide (CO₂), which is used in special fog machines. The effect occurs when highly pressurized CO₂ is released to the atmosphere. The abrupt transition from liquid to gas suddenly cools the CO₂, which causes the surrounding humid air to condense. The result: thick, white fog that sprawls across the stage like a billowing cloud. Because this fog is heavier than air, it stays close the ground – ideal for impressive walk-on-screen moments.
