Science Activity: Storm in a Jar

About 5 months ago, Harvey started to show an interest in clouds.  We did some clouds activities and had fun making an artificial storm from his favorite cloud, the Nimbus.

Here is the experiment we did:

Storm in a Jar

Aim:  Explore storm clouds


  1. Glass jar
  2. Small bowl
  3. Water
  4. Stirrer
  5. Shaving foam
  6. Syringes
  7. Food colouring

Note: You can use glow in the dark paint for an even more intense effect 🙂


  1. In the small bowl, mix a few drops of your desired food colour with some water
  2. Fill syringe with the solution.
  3. Fill the jar 3/4 with water
  4. Add the shaving foam on top of the water to form a “”cloud”
  5. Inject the food colour solution into the cloud.
  6. Watch what happens



A cloud is a large collection of very tiny droplets of water or ice crystals. These droplets are so small and light that they can float in the air. When enough of these droplets come together they become a visible cloud.

If these water droplets are over-saturated, the cloud becomes heavy and the gravity causes the water droplets to fall as rain.


Learning through play is definitely a fun way to engage a child and enhance family time.  Harvey enjoyed his stormy activity and we hope that he would apply this knowledge when it is actually raining outside.
