What are weather balloons?

A weather balloon is like a tiny airplane that floats up into the sky to help scientists learn about the weather.

Imagine you're playing with a helium balloon at home, it goes up because the helium is lighter than air. A weather balloon works in a similar way, but instead of just floating around your room, it goes all the way up to the stratosphere, where the sky meets space!

Inside the weather balloon, there’s a little box with tools that measure things like temperature, pressure, and wind speed. As the balloon rises, these tools send messages back down to Earth, kind of like sending postcards from high up in the sky.

Sometimes, the balloon even has a small camera or a special sensor that helps scientists see what's happening far above us. It’s like giving them a peek into the sky’s secret life!

When the balloon gets too high and the air gets too thin, it pops, just like when you blow up a balloon too much and it bursts! But don’t worry, the tools inside float back down so scientists can catch them and use them again.
