Story Synopsis

On a cold day, your breath can look like a little cloud—and children often wonder where it comes from. This story explains it in gentle, easy steps. It begins with a comforting fact: your breath is warm because it comes from inside your body. And it’s a little wet, because your mouth and lungs carry tiny bits of water you can’t see. When that warm, wet breath meets cold air outside, it cools fast. The invisible water bits stick together and become tiny droplets. Many tiny droplets together look white, like mist. Miluna keeps the tone cozy and simple, perfect for young listeners. Curiosity stories like this help children connect reading with everyday observations—building early science thinking and a gentle love for learning without turning bedtime into a lesson.
