JJ Thomson Cathode Ray Tube Experiment: the Discovery of the Electron

In 1897, JJ Thomson discovered the electron in his famous cathode ray tube experiment.  How did it work and why did Thomson do the experiment in the first place?  Watch the video and find out!


As usual a big thank you to the fabulous Kim Nalley for her background music and her version of Schoolhouse Rock's "Electricity, Electricity" for my intro song.
