How to build and operate a simple mass spectrometer. Please ask questions in the comments, as always. (I had to re-upload this video to fix the ending --I'm very sorry if your early comments were lost!)
Scientific American article: scientificamerican.com/article/the-amateur-scientist-1970-07 $7.99 is a good value for the entire back issue in plain PDF format, and an example of a publisher being reasonable. I'm happy to support this.
