Creepy Cauldron
To create a spooky scene at your Halloween party, purchase dry ice from your local grocery store's seafood department or ice supplier. Using tongs or thick gloves, place the dry ice in a watertight container; cover with water. Warm water will create more smoke, but it will disappear quickly. Cooler water will produce less dense smoke, but it will last longer. If the amount of smoke decreases during your party, add more dry ice and water.
Editor's Note: Do not handle dry ice with your bare hands. Use tongs or thick gloves. Keep dry ice out of the reach of children.
