Looking somewhat unstable particle detector for your home? How about a liquid at boiling point of entering?
With this basic principle, Donald Glaser
development in the mid-twentieth century bubble chamber. In essence it was a cylinder containing a clear liquid at a temperature just below its boiling point. But the temperature depends on the pressure. A piston moving down the pressure and began to form bubbles as the liquid quickly came to a boil. And, as in the cloud chamber, radiation favored the formation of ions and these bubbles. Bubbles grew rapidly with decreasing pressure. So the problem is transferred to the detection, among a lot of bubbles, a trail, a path, which indicates the presence of radiation, electric charge and even speed. It used to cameras sets arranged around the cylinder. This achievement provide the Nobel prize to its inventor.
But I can not finish without mentioning the most famous particle counter and "peliculero" of all. The Geiger counter . This detector has a similar principle to the above. Here the power imbalance. We have a closed tube filled with gas with a strong electric field. A field weak enough to not start gas electrons but strong enough to accelerate. Thus, a weak radiation can remove an electron to be attracted to the positive. To gain speed and hit other atoms will fall off even more electrons causing an "avalanche" electron, in short, an electrical current. Something like a grain of sand that collapses a mountain of beach. Adding amplifiers and speaker, this current becomes the chirp of so many classic films. A change is not very accurate. The counter name is because it has the particles, or in some cases, gamma radiation, but it says nothing about its composition or energy.
I always was impressed by the ingenuity used to investigate decades or centuries without all the technology we now have at our disposal. Maybe it's a childhood memory. I can not help but imagine MacGyver using a bottle of Coca-Cola agitated as detector particles. Okay, sure, but would not work great on
