A nearly identical question has been asked before on this topic, but that thread did not help us any further.
Me and a classmate built a cloud chamber in order to see elementairy particles (we aren't working with a radioactive source). We use a very standard set-up, but it does not appear to be working. We see little droplets forming and falling down and condens on the bottom plate, howeve, we do not see any tracks. We have made it work once beforewith a more primitive set-up:
We put a simpel aquarium box with the bottom on dry ice covered in a garbage bag. We used isopropyl alcohol (more than 95% concentration) and a dishcloth as absorber. We put all of this in a cardboard box isolated with styrofoam.
The only thing we then changed was turning the box upside-down and adding a metal plate in between the ice and box. Does anyone know why it might not be working?

for his invention of the Wilson cloud chamber, which became widely used in the study of radioactivity, X rays, cosmic rays, and other nuclear phenomena.
