This activity demonstrates the formation of fog and clouds in the atmosphere. The cold air from the ice cubes collides with the warm and moist air in the bottle, causing the water to condense, forming an eerie fog.

Directions:

1. Fill the jar completely with hot water for about a minute.

2. Pour out almost all the water, leaving about one inch in the bottom.

3. Put the strainer or bag over the top of the jar.

4. Place ice cubes in the stainer/bag

5. Watch what happens!
