I still don’t have a reliable setup, but some recent changes I made to my cloud chamber have resulted in this very satisfying display of subatomic contrails.  Here are a couple of recordings.  The first documents when I was stunned to see multiple concurrent trails and I called for Poldi to witness it.

The second video is a sustained view for several minutes, placed to background music, to mesmerize those of us who are susceptible. Think about it. This is a visual representation of the radiation that is all around us! Expand to full screen for best effect.

If you’d like to read about how I got here, the previous post describes the project of building the cloud chamber.
