What Is the Science Behind the Rain Cloud in a Jar Experiment?

Through the heat of the sun, water vaporizes into the sky and forms clouds which are symbolized by our shaving cream.

As we add food coloring, the cloud slowly takes in our colored rain droplets.
The clouds fill up and hold as much as they can take in before reaching their abundance. That’s when the rain falls.

Fun Facts About Rain and Rain Clouds

  • There are different types of clouds the 3 most common ones are: cirrus, cumulus, and stratus clouds.
  • Did you know that water can also fall from the sky in the form of hail, sleet, or snow?
  • Rain is an important part of our water cycle. Without water, most parts of our planet would turn into deserts. To learn more about our water cycle take a look here.

  • To improve your children’s fine motor skills you can also use small plastic containers and a dropper instead of food coloring. Just add water to each container, add a couple of drops of food coloring to it, and stir it. Let the kids use this colored water to create rain with their pipettes.
  • Besides teaching your kids about the weather this cool rainbow rain cloud experiment also gives you the perfect opportunity to explain to your children the concept of mixing colors and how new colors are created. Use the primary colors red, yellow, and blue and see what happens when they mix when the rain falls in the water.


My kids love this colorful rainbow in a jar weather activity and want to do it over and over again! It’s a creative way to illustrate how rain is falling from clouds.

Your children can learn a lot from this hands-on STEM activity, such as exploring the weather concept, including clouds, rain, or even the whole water cycle, introducing new vocabulary and the concept of cause and effect.

Therefore it is a perfect rainy day activity I can fully recommend!
