Build Your Own Cloud Chamber!

Cloud chambers are nifty little tools which physicists used in the 1920s to 1950s to study ionizing radiation. They were responsible for the discovery of the positron in 1932, which garnered Carl David Anderson the Nobel Prize in Physics in 1936.

After the 1950s, the Bubble chamber became the more useful tool to study radiation, but cloud chambers remain the simplest and easiest to build.

In fact, you can even build one yourself! Here’s a cool video demonstrating how they work and how you can build one:
