Here is a much simpler detector: A bottle of Corona (or any other beer in a long-necked, clear bottle) makes a workable cloud chamber. Chill well in the freezer, and watch the neck closely as you open it. You may see the streak of a cosmic ray passing through just as the cloud of condensation forms. Of course, as a bonus, it may take more than one try…. It's not an ideal project to do with your teen-aged child—a soda doesn't get cold enough, it has to be a beer. And yes, it really does work.

Will need some source for this. This sounds virtually impossible to pull off in practice even if it'd work in theory.

  Parts required for particle detector: Glass container Alcohol vapor Super-cold bottom (-26c or colder) Technically all of the above would be present in a neck of a really cold beer, as it is being opened. But I don't think my fridge can make the beer cold enough. Soda obviously doesn't work because it contains no alcohol vapor. Also soda is solid at -26 c, unable to release vapors whereas beer will still be a liquid (I think probably depends on the beer).

    I'm pretty sure I saw beer bottles break in my freezer due to content freezing. Don't know about a corona specifically thought

      I managed to freeze a bottle of beer the other week when I put some in the freezer to cool down and forgot about the last one. Bottle didn't break though the contents were sadly inaccessible - seemed to be an opaque white viscous slurry.
