Cloud in a Jar

This activity combines condensation, water cycles, and the state of matter to teach children about the formation of clouds. Using household materials like a jar, hairspray, and water, get the conversation going with your little ones about how water cycles through an environment and how clouds are formed in the sky. 

One method to this activity includes hairspray, ice, a jar with a lid, and about 1/3 cup of hot water. 

  • Pour the hot water into the jar and swirl it around to warm up the sides of the jar
  • Turn the lid upside down and place it on the top of the jar. Place several ice cubes onto the lid, and allow it to rest on the top of the jar for about 20 seconds.
  • Remove the lid, quickly spray a bit of hairspray into the jar, and then replace the lid with the ice still on top. Watch the cloud form.
  • When you see a good amount of condensation form, remove the lid and watch the “cloud” escape into the air.
