Experiment at home!
With the help of a water bubbler you can make clouds in the bottle yourself. Fill a bottle with water and screw it into the sparkling water maker. Press the bubble button while observing the layer of air above the water near the neck of the bottle.
Don’t have a sparkling water maker at hand? Then watch the two videos:
Introducing carbon dioxide into water increases the pressure in the bottle. If this becomes too large, a valve on the soda maker regulates the pressure equalization.
In this case, the pressure drops very quickly. As with clouds in nature, this means that suddenly less water vapor can be released into the air. The water vapor condenses and clouds or fog are formed.
