Making Fog Puffs with Dry Ice



Whether you’re looking for a science experiment for kids or simply looking for a way to WOW them, this Fog Puff experiment is the perfect way to go. You likely already have most of the items you need in your pantry or craft closet, and it takes no time to prepare but can entertain you and your kids as you try to make different shapes and sizes of fog puffs with the simple tap of your finger! You can watch a video on how to do this experiment or follow the directions below!

What You Need to Make Dry Ice Fog Puffs:

  • Tongs
  • Protective gloves
  • Dry Ice cubes, roughly the size of gumdrops
  • Plastic cup
  • Scissors
  • Rubber band
  • Cling wrap
  • Warm water

Step 1: Cut a hole about the size of a quarter in the bottom of a plastic cup.

Step 2: Cut a sheet of cling wrap that will cover the entire opening of the plastic cup.

Step 3: With gloves and tongs, carefully add dry ice cubes to the plastic cup. Make sure that your dry ice pieces are larger than the small hole in the bottom.

SAFETY NOTE: To cube your dry ice from a block, wear protective gloves and eyewear, place the dry ice block in a towel, and carefully hit the block with a hammer or mallet. Do not chip at dry ice with a knife or other sharp object.

Step 4: Tightly place the cling wrap over the opening of the cup and secure tightly with a rubber band.

Step 5: Gently flip the cup so the cling-wrapped side is on a flat surface. Then, slowly pour a small amount of warm water (about 1/8th of a cup) through the hole in the bottom of the plastic cup.

Step 6: Gently pick the cup up and tap on the cling wrap to initiate the fog puffs or lightly squeeze the cup to initiate a fog stream.

Safety Notes:

Parental supervision is required.

Do not aim the cup at any humans or animals.

Always use gloves and tongs when handling dry ice.
