Cloud Chamber

The tracks of sub-atomic particles are captured as they leave condensation trails in a cloud chamber. The "rain" is condensing alcohol, and the particle source is a small button of americium-241. Most of the trails are probably alpha particles, others are cosmic rays and stray particles from background radiation.
