What are air bubbles?

Air bubbles are little pockets of air that get trapped inside something else, like when you shake a bottle of soda and little air bubbles pop up in it.

Imagine you're playing with a glass of water. If you drop a pebble into the water, ripples form around it. Now imagine you drop a tiny air bubble instead, it floats up to the top because it's lighter than the water.

Air bubbles can be found in many places. When you blow bubbles with a wand and soap, those are air bubbles too! They’re like little balls of air wrapped in a thin layer of soap.

Sometimes, when air bubbles reach the top, they pop, just like when you burst a balloon. That's because the air inside wants to escape, and it finds the easiest way out: through the soap film or the surface of the water.

So next time you see little air bubbles rising in your drink, remember: they're just tiny pockets of air having a fun journey to the top!
