Okay, I read Dr. Clark's book ' The Cure For All Diseases ' and I am a total novice when it comes to science, chemistry; anything along those lines. However, I am plannning to make the zapper she talks about (the one with the shoebox), and when I am done, I am not sure what I am supposed to do. She talks about an oscilioscope, and when I asked an electronics professional what it was, he said that it is very expensive, something like thousands of dollars. Anyway, do I need a frequency generator or something in order to use the zapper when I am done? I am pretty lost right now.
