“I yuvvvv bubbles!” – Hugo, 4
We agree with you, Hugo! Bubbles are the best. In fact, at KiwiCo, we love bubbles so much we created a Bubble Machine that you can build with your kids at home! We think bubbles are awesome because they’re a super fun way to play with science.
A bubble is a pocket of gas (like air) that is trapped in a layer of liquid. To make a good bubble the outer shell needs to be able to stretch without breaking. And the secret ingredient for stretchiness is soap! Adding soap to water stops the water from sticking together so tightly. Soap has a love-hate relationship with water–literally. One end of a soap molecule loves water and the other hates water. The soap molecules in a bubble want to have their water-hating ends far away from the water, and the water-loving sides close to it. This creates a soap-and-water sandwich, with the soap on the outside and the water on the inside. With just a little soap and water, you can create bubbles anywhere!
At-Home Bubble Activities & Experiments
Make stronger bubbles by adding corn syrup to your solution! Experiment with surface tension and see how bubbles stretch! Try dipping a coin or a paperclip into some soapy water, and see what happens when you drop it through a bubble!

Use electricity to break the water molecules apart into its parts — hydrogen and oxygen! The bubbles you see on the tips of the pencils are the hydrogen and oxygen gas created by this reaction. In fact, hydrogen gas is created at one of the pencils, and oxygen gas is created at the other. This process is called water electrolysis.

Oil and water famously don’t mix well. No matter how much you stir them together, they’ll always separate as oil rises to the top. But oil and water don’t avoid mixing because they don’t like each other; it’s because of their chemistry! In this project, you’ll learn more about the chemistry of oil and water and create a bubbly chemical reaction —both essential to making your Bubble Lamp bag groovy and fun.

Using some household items, it was easy to make a giant bubble wand and a bubble solution for giant bubbles. The kids loved taking turns trying to see who could make the biggest bubbles.
