Witness beautiful trails made by unseen cosmic particles that are constantly passing through us and our world. A cloud chamber gives us a glimpse into the invisible world of particles produced in the radioactive decay of naturally occurring elements and those generated when cosmic rays strike the top of the Earth’s atmosphere.
You will make your own mini-cloud chamber from simple materials and see a larger cloud chamber in action. Using a sealed plastic container, some pure alcohol and dry ice you will create a super-saturated environment where the invisible charged particles ionize the vapour in their path triggering a condensation process in the ‘cloud’. We will then discuss how a cloud chamber works and think about other even more elusive particles such as dark matter that scientists are unable to detect at present.
It is suitable for adults and children 12 and over (under 14s must be accompanied by an adult).
This event is taking place as part of the North Pennines Stargazing Festival 2018.
