Cloud in a Jar

  Primary | Materials | Views: 358

You will Need:

  • A jar with a lid
  • 1/3 cup of hot water
  • Ice
  • Hairspray

Health and Safety: Ensure you take care when handling hot water, have an adult to help you with this.

What to Do:

  1. To do this experiment, pour the hot water into the jar. Swirl it around a bit to heat up the jar.
  2. Turn the lid upside down and sit it on the top of the jar.
  3. Place some ice cubes on the lid and allow to rest for about 20 seconds. Next, remove the lid and spray some hairspray into the jar and put the lid (with ice) back on the top of the jar.
  4. You should start to see a cloud appear. Once a decent amount has formed, remove the lid and watch the cloud escape the jar!
