Cloud Chamber 1224 1 White jack or targetThis large cloud chamber allows the visualization of atomic particles as they pass through a super saturated Isopropanol vapour, cooled by dry ice. Energetic charged particles collide with the gas molecules causing a trail of ionized particles. These ionized gas particles act as nucleation sites on which the super saturated alcohol vapour condenses, leaving a cloud like trail that lasts for a few seconds. The built in LED lighting is collimated to
