AUGUSTA, GA (WFXG) -

Clouds come in all shapes and sizes. Some are tall, some are short, some are big, some are small. But any cloud needs just three things to form.

To show this, we’ll create a cloud in a bottle. To do this, fill a 2-liter plastic bottle about a third of the way with warm water.

Water vapor evaporates into the air inside when the cap is put on the bottle and closed. That’s just one ingredient needed to make a cloud. Squeezing the bottle and letting it go drops the air pressure inside but nothing else happens. That's because a drop in air pressure and water vapor are not enough to form a cloud. The last ingredient comes from the smoke from a match.

Once the cap is put back on and closed, squeezing the bottle again and letting it go, forms a cloud. That’s because dust, smoke, or other particles are needed to form clouds.

    Clouds: you can hardly go a day without seeing at least one in the sky. But did you ever wonder why some clouds produce rain and others don’t? You can try a really simple demonstration to see how clouds make rain.

    The Earth is surrounded by an envelope of air known as the atmosphere. You can’t really see it or feel it. We probably take for granted that it is even there at all, but the pool of air above us is about 60 miles high and is always pushing down on us. This is where we get air pressure.

    Hurricanes fall under a class of storms known as tropical cyclones. These systems are large rotating areas of low pressure hundreds of miles across with organized thunderstorms, but no fronts.
