Rainbow Bubble Blower
easy STEM activity for kids
Looking for a fun bubble activity for kids that’s easy to set up and guaranteed to bring endless giggles
This DIY rainbow bubble blower is the perfect outdoor activity for Preschool and Kindergarten kids.
With just a few simple household materials—like a plastic bottle, a baby wipe, and some bubble solution—you can create a magical stream of colored bubble snakes.
Not only is this a blast to play with, but it’s also a great way to explore the science of bubbles in a hands-on way.
In this step-by-step bubble blower tutorial, we’ll show you exactly how to make your own homemade bubble blower with bright, swirling colors.
Whether you’re looking for a summer backyard activity, a creative science experiment, or a quick and easy way to keep kids entertained, this activity checks all the boxes.
Grab your supplies, head outside, and get ready to watch the rainbow bubbles float and dance in the air!

What's the Science Behind the
Rainbow Bubble Blower?
This DIY rainbow bubble blower isn’t just a fun outdoor activity—it’s also a simple and exciting way to explore bubble science! But what’s really happening when you blow through the bottle and create a stream of colored bubble snakes?
Bubbles form because of a property called surface tension. The soap in the bubble solution lowers the surface tension of water, allowing it to stretch and form thin films. When you blow air through the top of the bottle, the soap film expands, trapping air inside and creating a long chain of bubbles.
Unlike traditional round bubbles that float away, the bubbles in your homemade bubble blower stick together, forming a foamy snake. This happens because of the way the air flows through the tiny openings in the baby wipe at the bottom of the bottle. The air is dispersed evenly, making lots of small bubbles that stay connected instead of forming one big bubble.
The food coloring added to the baby wipe mixes with the bubbles as they form, giving them a bright and colorful appearance. Each bubble traps a bit of the dye, creating a rainbow effect as they pile up into a foamy stream. The more colors you add, the more vibrant your bubble snake will be!
Over time, your bubbles will start to disappear. That’s because the water in the bubble solution slowly evaporates, breaking the thin soap film and causing the bubbles to pop. If it’s a hot or windy day, they’ll vanish even faster!
Surface Tension -The invisible “skin” on the surface of a liquid that holds bubbles together.
Air Pressure – The force of air pushing in different directions when you blow into the bottle.
Evaporation – When a liquid (like the bubble solution) turns into gas and disappears.
Liquid – A state of matter that flows freely, like water and bubble solution.
Solution – A mixture of two or more substances (like soap and water for bubbles).
