Always handle dry ice with insulated gloves or tongs, as direct contact can cause serious frostbite. Never touch it with bare hands, store it in an airtight container, or use it in an enclosed space. Use dry ice in a well ventilated area and keep it away from children and pets.

Place warm water in your cauldron and carefully add a few pieces of dry ice using tongs. The dry ice reacts with the warm water to create a thick, spooky fog that spills over the sides of your cauldron. For the best effect, use warm water and add more dry ice as needed.

Dry ice typically lasts between 18 and 24 hours in a well insulated cooler, but the fog effect lasts only as long as the dry ice is in contact with warm water. For the thickest, most dramatic Halloween fog, add fresh dry ice as needed and refresh the warm water when it cools.

Yes, but only in a well-ventilated space where carbon dioxide cannot build up. Never use dry ice in small, enclosed rooms, and keep it away from children and pets. For the safest and most dramatic effect, consider using your cauldron outdoors on Halloween night.
