Okay, so balloons are like big, round balls that can be filled up with air. When you blow air into them, they get bigger and bigger until they're really big and round. When they're too full, they might pop!
That's when the balloon makes a loud noise and all the air inside rushes out really quickly. It's like a mini-explosion!
There are lots of ways you can pop a balloon. You can accidentally sit on it, or you can use a sharp object like a pin or a needle to poke a hole in it. You can also twist and squeeze the balloon until it pops - but be careful!
Sometimes people like to pop balloons as part of a game or a party. They might have a competition to see who can pop the most balloons the fastest. It can be a lot of fun, but always remember to be safe and not hurt anyone or anything when popping balloons!
