My entry for X-Particles Challenge 2017. Got 3rd place.
Inspired by the 'cloud chamber' particle detector experiment, whereby decaying alpha particles are visualised in a sealed box filled with supersaturated alcohol vapour. The charged alpha particle from a radioactive element such as uranium ionises the gas in its wake, creating the characteristic vapour trails.
