Making Fog with Dry Ice

Dry ice can create fog when placed in water.  This is an especially popular
trick around Halloween to create a spooky atmosphere and is used often in
theater as well.  Here is how to do it yourself:

  • Add chunks of dry ice to water in a Styrofoam or other insulated
    container.  The chemical reaction will create a fog effect.  Using
    warm water will produce an even denser fog.

  • The fog will sink to the ground. You can use a fan on a low setting to
    move the 'smoke'.

  • The water will become carbonated, causing the fog to disappear.  
    You will have to replace the carbonated water with fresh water in
    order to maintain the effect.

  • Room temperature does matter - you will get the most fog in a cool
    room.

It is very important to keep in mind that dry ice can be hazardous.
