This document describes an experiment to create a cloud in a jar. Students cover the bottom of a jar with water and place a lit match inside under a rubber glove-covered opening. When the match is blown out, the change in pressure and temperature causes water vapor in the air to condense onto smoke particles from the match, forming a small cloud inside the jar. The document then discusses different types of clouds like stratus, altocumulus, cirrus, cumulus and cumulonimbus clouds. It concludes by reflecting on how God created the diversity of clouds and everything else in nature.
