Rain Cloud in a Jar – A Mesmerizing Weather Experiment for Kids 🌧️✨
Get ready to bring the magic of weather right into your kitchen! This Rain Cloud in a Jar experiment is a simple, hands-on way to help kids visualize how rain forms. It’s easy, inexpensive, and fascinating for all ages — grown-ups included! Best of all, it uses supplies you probably already have on hand.
A fun and educational way to explore the science of rain
Supplies You’ll Need
- 1 large clear glass jar or cup (a big mason jar works great!)
- Water
- White foamy shaving cream (not gel!)
- Blue food coloring (or blue watercolor paint)
- Small cup or bowl
- Dropper, spoon, or small measuring cup
👩🔬 Instructions
- Set up your atmosphere:
Fill your clear jar about ¾ full with water. This represents the air or atmosphere. - Create your cloud:
Spray a generous layer of shaving cream on top of the water. This fluffy layer is your cloud! Try to cover the surface of the water evenly. - Mix your rain:
In a small cup or bowl, combine a few drops of blue food coloring with a bit of water. (If you’re using watercolor paint, mix a small amount of blue paint with water.) - Make it rain:
Slowly drizzle or drop the colored water onto the shaving cream cloud. You can use a dropper, spoon, or carefully pour small amounts at a time. - Watch the magic happen:
As the shaving cream cloud becomes saturated, the blue liquid will begin to break through, falling into the clear water below — just like rain falling from heavy clouds! - Keep exploring:
Continue adding colored water and observe how the “rain” changes. Talk about how real clouds work — when they get too full of water vapor, rain begins to fall!
Fun Tips & Variations
-
Try different colors to create a rainbow rain effect! 🌈
-
Use a flashlight behind the jar for an extra cool visual.
-
Compare what happens when you add the colored water slowly vs. quickly.
