Have you ever looked up at the sky and wondered how clouds are made? Today, we’re going to do a fun experiment at home to make our very own cloud using air! We call this experiment “Cloud in a Bottle.” Remember, it’s important to have a grown-up’s permission and help.
To make a cloud, we need three things:
Let’s get started!
Here’s a cool trick: you can make your cloud disappear! Just put the stopper back in the bottle and pump some air back in. This adds pressure and makes the cloud go away. You can repeat the process to see the cloud form again by releasing the pressure.
Did you know that real clouds in the sky form in a similar way? They are made of tiny water droplets or ice crystals that cling to dust or other particles in the air. When the air cools down, these droplets come together to form clouds!
And that’s how you make a cloud in a bottle! Have fun experimenting and learning about the science of clouds!
Cloud Observation Journal: Start a cloud observation journal. Each day, look up at the sky and draw the different types of clouds you see. Are they fluffy like cotton balls, or do they look like thin wisps? Write down what the weather is like each day. After a week, see if you notice any patterns between the types of clouds and the weather.
Make a Cloud Collage: Use cotton balls, glue, and blue construction paper to create your own cloud collage. Try to make different types of clouds like cumulus, stratus, and cirrus. Use your imagination to create a sky scene. Share your collage with your family and explain what each type of cloud might mean for the weather.
Question Time: Think about why clouds might be important for our planet. Discuss with a friend or family member how clouds can affect the weather and why they are important for plants and animals. Can you think of any ways that clouds help people in their daily lives?
Sure! Here’s a sanitized version of the transcript:

Have you ever looked up in the sky and wondered how clouds form? Well, in today’s at-home experiment, we are going to create our very own cloud using air. I call this one “Cloud In A Bottle.” Remember, for all the young scientists at home, it’s important to have a grown-up’s approval.
For this experiment, you will need a bike pump, a stopper, safety glasses, a plastic bottle, and some isopropyl alcohol. This is something your parents probably have for cleaning around the house.
There are three ingredients needed to make a cloud. The first is water vapor. The second is something for that water vapor to cling to in order to form the cloud. The third is a low-pressure environment with cooler air.
First, we will add a little bit of isopropyl alcohol to our bottle and swirl it around. There is some water in isopropyl alcohol, which helps create our water vapor. Additionally, there are other molecules in isopropyl alcohol that provide something for the water vapor to cling to.
Next, I will put on my safety glasses for protection. We will bring in our bike pump, insert the stopper into the plastic bottle, and pump it about five to ten times. This creates a high-pressure environment and slightly warms up the air. However, we want the opposite effect.
Now, I will remove the stopper, which will release the pressure all at once, creating a low-pressure environment with cooler air. And just like that, you have your cloud in a bottle!
The interesting part is that we can make our cloud disappear by removing that third ingredient. Simply put the stopper back in, ensure it’s secure, add some pressure, and gradually, we can make our cloud disappear. The fun part is that you can repeat this process by bringing back that low-pressure environment and cooler air.
And that’s how you make a cloud in a bottle!
