Materials

  • Glass jar with a removable lid
  • Water
  • Ice
  • Aerosol spray (Pam cooking spray, Spray-on Sunscreen, Hairspray)

  1. Remove the lid from your glass jar and fill about ⅔ of the glass with water.

  2. Microwave the jar of water without the lid for about 2 or 3 minutes (don’t let the water boil). THE JAR WILL BE HOT SO BE CAREFUL REMOVING IT FROM THE MICROWAVE. Ask an adult for help or use a potholder.

  3. Place the lid upside down on the jar and put a few ice cubes on the lid. Wait 30 seconds

  4. Remove the ice cubes, lift the lid, give a quick aerosol spray into the jar and close the lid quickly.

  5. What happens? Why do you think the ice needs to be outside the jar? Clouds form when moist, warm air cools and the moisture in the air condenses and settles on dust, dirt, and other tiny air particles. In this experiment, the hairspray acted as tiny air particles.
