Why Do Bubbles Pop?

Imagine a bubble as like a tiny soap bag filled with air. When it pops, it’s because the soap can no longer hold on to the air inside. The air escapes quickly and makes a pop sound. It's kind of like when you let go of a balloon, the air rushes out fast!

Bubbles are made of water and soap. When they pop, it’s because the soap gets too thin or there’s something that breaks the surface, like a little bump on the bubble.

After a bubble pops, you might see tiny bits of soap left behind, like a wet shadow where the bubble used to be.
