Have you ever wondered how clouds form? In this activity, you can make your own cloud to see for yourself!
Clouds form from the condensation or freezing of water vapor. Condensation is the process of a gas changing into a liquid. In this activity, the gas is water vapor and the liquid is the cloud you create. When water vapor cools, it turns into a liquid – or condenses – onto a surface.
For example, take a cold water bottle outside on a warm day. You will notice that water droplets form on the outside of the bottle. These droplets are water vapor from the atmosphere condensing on the surface of the bottle. They do this because the surrounding air cools when it touches the bottle. Clouds form the same way. Water vapor in the atmosphere cools and condenses on particles in the air, creating a cloud.
