Making a cloud with this palm-sized pump 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 (10.5") tall.
