Making a cloud with this apparatus is easy. Remove the top and put a few drops of water inside the bottle. Add air to the bottle using the pump and watch: as the pressure increases, so does the temperature. Actuate the quick-release top and due to rapid decompression, a cloud forms instantly inside the bottle! A Liquid Crystal thermometer strip measures temperature changes throughout the experiment. This hands-on activity teaches the relationship between pressure and temperature in a closed container. Approx. 26 cm tall.

Demonstration can be carried out over and over again.  Bottle is made of PET plastic meaning it's ideal for student use.

Affordable and ideal for classroom sets.
