Boil up some witches brew

Dry ice -- frozen carbon dioxide -- is the age-old secret behind bubbling witches' brews, magic potions, mystical cauldrons and other props that call for a thin blanket of harmless mist. Drop a chunk into water and you'll set off a violent (but safe!) bubbling reaction as carbon dioxide gas is released.

Warning: Dry ice is extremely cold and should not be touched with bare hands. It is definitely not food, either, so don't put it in your mouth. The mist itself is carbon dioxide, and is safe to touch and breathe.

Make scarier fog

The secret to creating graveyard-style fog that hugs the ground, rather than spewing upward, is to chill the fog as it exits your fog machine. You can MacGyver a cheap fog cooler using a styrofoam ice chest and some piping from your local hardware store that's at least 4 inches (10 centimeters) in diameter and 4 feet (1.2 meters) long.

Cut holes in both ends of the ice chest, near the bottom, then run the pipe though both holes. Fill the chest with ice, so the ice covers the pipe, close the lid, point your fog machine nozzle into one end of the pipe, and blast away.
