What Is a Cloud?

A cloud is a collection of tiny water droplets or ice crystals floating in the air. They form when water vapor cools down and turns into liquid water or ice.

What Clouds Are Made Of

• Water vapor — the invisible gas that starts it all.

• Tiny water droplets — millions of them, so small they can float in the air.

• Ice crystals — formed in the colder parts of the cloud.

• Dust and particles — serving as the “seed” for droplets to form.

Fun Cloud Facts

• One cubic meter of a cloud weighs about 1 pound.

• A large thundercloud can weigh thousands of tons!

• Clouds come in many shapes and types: cumulus, cirrus, stratus, and more.

How We Make Clouds at 

Nitro7Lab

In our program, we create artificial clouds using liquid nitrogen. It’s exciting, safe, and helps kids understand how clouds form in nature.

Science isn’t just formulas and experiments — it’s also magic you can see with your own eyes!
