How to build a Cloud Chamber
Why Physics Stack Exchange recommends it
Physics Stack Exchange users link it when someone asks how particle tracks can be seen or photographed without a big lab.

What it is
A short how-to video from the US LHC channel, filmed in CERN's S'Cool Lab, showing how to build a simple cloud chamber that makes particle tracks visible. It accompanies written instructions published in Symmetry magazine.

And of course you can build a particle detector in your kitchen in just a few minutes, if you're interested in observing less exotic particles: [this video]
Recommends The_Sympathizer · 2019-07 · Physics Stack Exchange · on “Alternative ways to take particle tracks photographs in a cloud chamber”
You can see the tracks using any half-decent digital video or photographic camera. Just look at this video on Youtube, and many more like it, for a demonstration: [this video]
Cites Jiang-min Zhang · 2017-03 · Physics Stack Exchange · on “Radon or cosmic ray?”
My student constructed a cloud chamber to detect the background radiation. It is very simple and efficient. But the question is, is the radiation mostly from the Radon gas or the cosmic ray? See some video here: [this video]
