====Procedure====  
  - Cut open the top of a pumpkin and scoop out the seeds and pulp.
  - Carve a face or design into the pumpkin, keeping in mind that fog will sink and flow more easily through the mouth than the eyes.
  - Place a plastic container filled with warm water inside the carved pumpkin.
  - Add a chunk of dry ice into the water.
  - Replace the pumpkin lid to trap the fog so it flows through the carved openings.
  - Add more dry ice as needed to keep the fog effect going.

/*******************************************************************************************************/

====Variations====
  * Place a colored light or glow stick inside the pumpkin for a glowing fog effect.
  * Try carving different facial expressions or hole sizes to see how fog flows differently.

/*******************************************************************************************************/

====Safety Precautions====
  * Always wear gloves when handling dry ice to prevent frostbite.
  * Do not touch dry ice with bare skin.
  * Use warm water for stronger fog, but avoid boiling water which can splatter.
  * Keep children and pets at a safe distance from dry ice.
  * Use in a ventilated space since carbon dioxide gas will accumulate.

/*******************************************************************************************************/

====Questions to Consider====
  * Why does warm water make more fog than cold water?
  * Why does the fog flow downward instead of rising like steam?
  * How does dry ice produce fog without turning into liquid first?
  * What factors affect how long the fog effect lasts?
