Looking for a hands-on science activity that’s as fun as it is educational? The DIY Rain Cloud in a Jar is a simple yet visually captivating experiment that demonstrates how rain forms in the atmosphere. Perfect for kids, students, or curious adults, this project turns everyday household items into a mini weather system — right inside a jar!
With just a few supplies and a little imagination, you can create your own rainy day indoors and learn a little meteorology along the way.
🌧️ What Is a Rain Cloud in a Jar?
The rain cloud in a jar experiment mimics how rain falls from clouds. In this demonstration:
The shaving cream represents the fluffy clouds.
The colored water stands in for rainwater.
As the “cloud” gets saturated, it can no longer hold the “rain,” and colored water begins to fall through — just like real rainfall!
🧪 Supplies You’ll Need:
A clear glass jar or cup
Shaving cream (foamy kind, not gel)
Water
Food coloring (blue works best, but any color will do)
A dropper or spoon
