Soap bubbles are made when water, soap, and air come together to make something light and shiny like a balloon.
Water is what we drink every day, it’s wet and slippery. Soap is the stuff you use to wash your hands or your face, it makes things clean by helping dirt float away.
When you mix them together in a bottle, they become a special kind of liquid that can hold air inside it. When you blow on it with a blower or a straw, the air goes into the liquid, and it stretches out to make a bubble, like when you stretch a balloon.
How Bubbles Stay Up
Bubbles stay up in the air because they are light, just like a feather. The soap helps keep the water from falling apart too quickly, so the bubble can float for a little while before it pops.
When the bubble lands on the floor or breaks into tiny pieces, it’s like when you drop your favorite juice box, it makes a big mess of liquid and air that you can see and feel.
Examples
