This raining rainbow cloud in a jar not only makes it rain, but it makes a hurricane! A simple STEM project for little ones (and older kids love it too!)
Science experiments for kids can be super complicated. Just the other day, we did a full-blown energy efficiency experiment with control groups, recording, measuring, variations, and the whole nine yards. That was really cool, but, we don’t always have time for such complicated and involved science lessons and STEM activities.
Little kids, too, love discovering science and experimenting but they’re not ready for complicated projects.
If you’ve ever had a kid ask you how rain works, you can show them easily with this simple science lesson! It’s the perfect addition to your spring STEM activities!
The raining rainbow cloud in a jar (our version was a hurricane!), shows kids how clouds hold on to moisture until it gets too heavy, then, it releases it all in a big gush of rain! This experiment fits in perfectly with our other St. Patrick’s Day STEM activities.
This activity is one of our favorite technology activities for kids!
Easy Science for Kids: Raining Rainbow Cloud in a Jar
Find out how to make your own cloud in a jar below:
This project is appropriate for toddlers and preschoolers (as long as they don’t try to eat the shaving cream).
What you’ll need for your raining rainbow cloud in a jar:

If you’re in a rush, these are our favorite weather science kits.
- Shaving cream
- Mason jar
- Food coloring in as many rainbow colors as you can find (we found red, yellow, green, blue, and purple)
Fill your jar mostly full of water. Fill the top of the jar with shaving cream. Don’t make the shaving cream layer too thick if you have impatient kids or they will get bored before the liquid travels all the way through the shaving cream.
Drop the food coloring on the surface of the cloud in a rainbow pattern. We wanted to see if we could actually get the clouds to rain a rainbow shape, but that didn’t quite work out.
But we were left with some pretty, swirly colors!
Keep adding colors a bit at a time until your whole jar is a hurricane of swirling color.
