Make Your Own Fog!

Make Your Own Fog! | Science Fair Projects | STEM Projects
Have you ever wondered how fog forms? You can find out by making your own fog in a bottle! All you need is two bottles, hot and cold water, and an ice cube.


The hypothesis is that fog forms when warm, moist air is cooled quickly.

Method & Materials

You will fill one bottle with hot water and the other with cold water, pour out the hot water, and then place an ice cube in the mouth of each bottle.
You will need two bottles, hot and cold water, and an ice cube.


After the experiment, you will observe that the warm, moist air in the bottle with hot water is cooled quickly and forms fog. The fog is denser in the bottle with hot water than in the bottle with cold water.

Why do this project?

This science project is so interesting and unique because it allows you to observe the formation of fog in a controlled environment.

Also Consider

Experiment variations to consider include using different temperatures of water and different sizes of ice cubes.
