How to Make a Rain Cloud in a Jar

Rainy days can be a drag, especially when cooped up inside with energetic preschoolers. But what if you could bring a mini storm indoors for captivating science fun? That’s where the magic of a rain cloud in a jar comes in! This easy experiment is a surefire way to turn frowns upside down and transform your kitchen into a mini weather lab.

The best part? You don’t need a fancy degree in meteorology to pull it off. We’re discussing everyday household items and a few minutes to set up. It’s the perfect opportunity for curious young minds to explore the wonders of water, density, and the fascinating rain process.

Imagine their delight as they watch a cloud form, then witness a magical downpour inside the jar! This preschool weather activity is more than just fun and games – it’s a chance to spark their curiosity about the world around them and nurture a love for science.

So ditch the boredom and grab your little scientists. It’s time to create a rain cloud in a jar and watch the learning (and maybe a little playful sprinkling) begin!

Forget the rainy day blues! This rain cloud in a jar experiment isn’t just about keeping kiddos entertained – it’s about transforming your living room into a captivating mini weather lab. Imagine the look on their faces as they witness the magic of cloud formation and a miniature downpour happening right before their eyes.

It’s like having a front-row seat to a weather phenomenon happening in the comfort of your home! This experiment sparks curiosity, ignites a sense of wonder, and turns a potentially dreary day into an opportunity for scientific exploration.

So grab your lab coats (or aprons!), because it’s time to unleash the inner meteorologist in your little scientists!

Rain Cloud in a Jar

The rain cloud in a jar isn’t just fun and games (although it’s definitely both!). This exciting experiment is a fantastic way for young minds to delve into the fascinating world of science. As they create their own mini weather system, they’ll be exploring the properties of water, the concept of density, and even the process of rain formation.

They’ll see firsthand how water can change states (from liquid to gas and back again!), how density affects how things move (the colored water sinking through the shaving cream), and how clouds become heavy with water before releasing it as rain. It’s a captivating way to introduce these scientific concepts in a way that’s both engaging and memorable!

What You’ll Need

Clear Glass Jar: A mason jar or any other clear container that holds at least 2 cups of liquid will work perfectly.

Shaving Cream: Regular white shaving cream is ideal for this experiment.

Liquid Food Coloring (Optional): A few drops of blue or green food coloring will add a touch of realism to your rain cloud.

Dropper or Spoon (Optional): A dropper allows more precise control when adding the colored water, but a spoon can work in a pinch.

Rain in a Jar

Now it’s time to transform our jar into a mini weather system! Grab your supplies and follow these easy steps. Remember, we’ll be scientists today, so be careful and observe what happens!

First, fill your jar with water. Pretend it’s a big, empty cloud.

Now, squirt some shaving cream on top of the water in the jar. Be careful not to fill it up – we want room for the rain!

Look at our fluffy cloud! Doesn’t it look real?

Next, let’s make some rain! Carefully drip some of the food coloring onto the top of our shaving cream cloud.

The food coloring is sinking through the shaving cream cloud, like real rain falls from the sky!

Why does this happen? It’s because the food coloring is heavier than the shaving cream cloud. Cool, right? Like real scientists, we’re learning about water and how things move!

You can keep adding rain until our jar is full of colorful raindrops!

How do clouds make rain?

Have you ever wondered how rain falls from the sky? It all has to do with something called condensation! Imagine tiny invisible water particles floating around in the air. When these particles get cold, they huddle together and form water droplets – that’s condensation! These droplets get heavier and heavier until they can’t stay in the air anymore – plop! They fall down as rain.

Our rain cloud in a jar experiment is like a mini version of what happens up in the sky. The shaving cream acts like a fluffy cloud, full of tiny air pockets. The food coloring is like those invisible water particles. When we add the food color, it gets “stuck” in the air pockets of the shaving cream (like condensation). The more water we add, the heavier it gets, just like a real cloud. Eventually, it gets too heavy and “rains” down into the jar!

This is a simple way to understand how density (how heavy something is) and condensation combine to bring us rain!

Preschool Science Experiments

Curious minds are everywhere, and preschoolers are especially keen to explore the world around them! Here are some fun and easy science experiments you can do with your little scientists using common household items at home.

We hope you and your little scientists had a blast creating your very own rain cloud in a jar! This experiment is just a peek into the awe-inspiring world of science. Imagine all the incredible things there are to learn about weather, water, and the amazing world around us!

This is the perfect time to nurture their curiosity. Encourage them to ask questions, explore their surroundings, and keep those little minds wondering. Who knows, maybe your rain cloud in a jar will spark a lifelong love of science!

Rain Cloud in a Jar

Rain Cloud in a Jar

This science experiment lets kids create a mini rain cloud in a jar using shaving cream and water, teaching them about water and density.

Active Time 15 minutes
Total Time 15 minutes
Difficulty Easy


  • Clear Glass Jar
  • Shaving Cream
  • Liquid Food Coloring
  • Dropper


    1. Gather your supplies. Fill your jars with water to about 2 inches from the top. If you fill your jars too full, you won’t have enough room to make the “cloud”.
    2. Also, if you can, let each child create a rain cloud in a jar. Lessons tend to “stick” better when done in a hands-on way.
    3. Spray a layer of shaving cream on top of the water in each jar. This will represent the cloud. Ensure you don’t make your “cloud” too compact, or the “rain” will have trouble getting through it. Make sure to spray it loosely on top.
    4. Once kids have their clouds “just right,” let them squirt a few drops of food coloring around the top and sides of the shaving cream cloud. They can use all one color or multiple colors.
    5. You will need liquid food coloring. Gel coloring won’t drip like you need it to for this experiment.
    6. The food color will slowly leak through the cloud, which will look like rain coming through the clouds.
