Ever been to a Halloween party and seen that spooky fog rolling across the floor? Or maybe you’ve watched a band perform live and noticed a mysterious haze drifting around their feet? Nine times out of ten, that’s not smoke—it’s dry ice fog, and it’s surprisingly easy to recreate at home (or at your business).

We’ve seen people use it for everything from wedding entrances to science fair volcanoes. And yes, it’s just as cool as it sounds.

So… what is dry ice fog, really?

Dry ice is just solid carbon dioxide (CO₂), and it turns directly from a solid to a gas at -109°F. That’s cold. 🥶

When you drop a chunk of it into warm or hot water, it rapidly sublimates (fancy word for “goes from solid to gas”) and creates a thick fog of water vapor. The visual effect? Super dramatic. No flames, no chemicals—just science doing its thing.

What You Need to Create Fog

It doesn’t take much to get started:

Here’s how it works:

  1. Fill your container about halfway with hot water.
  2. Using gloves or tongs, carefully drop a few chunks of dry ice into the water.
  3. Watch as the thick fog begins to pour out. You can refresh the fog by adding more hot water once it starts to slow down.

Pro Tip: For that floor-hugging fog effect, use a shallow container and place it near the ground. The fog is heavier than air, so it naturally spills downward and creeps along surfaces.

Safety First (but don’t worry, it’s not rocket science)

While dry ice is fun and safe when used properly, there are a few things to keep in mind:

Real Talk: Why Dry Ice Fog is Better Than Smoke Machines

Unlike traditional fog machines that use glycol-based fluids (which can smell weird or trigger smoke detectors), dry ice fog is clean, scent-free, and totally natural. It’s also silent—no humming or buzzing—just pure visual impact.

That’s why people love it for weddings, film shoots, theater, haunted houses, and even backyard parties. It’s budget-friendly and easy to control with a little practice.
