The cloud chamber was one of the first particle detectors. Today, cloud chambers are only used in education. It is very easy to build a cloud chamber with everyday material, dry ice, and Isopropyl alcohol. Below we provide a DIY manual including many information on how to interpret the observations, and what do with cloud chamber (e.g. using balloons as radioactive sources).
