Cloud Chamber (16-19 years)
Build your own particle detector to make ionising particles visible and study the properties of different particle tracks.
Although we can't see them, ionising particles are part of our everyday life. For example, cosmic particles interacting with the upper layers of the Earth’s atmosphere produce showers of new particles, some of which reach ground level. Naturally occurring radioactive elements in the air emit alpha particles. Through interaction with certain detector materials, we can make tracks of ionising particles visible.
