They had a display of "quack medical devices", that included a high-voltage AC device attached to glowing neon-bulb-type tubes. The idea was that these tubes would be pressed against a person's flesh, thus capacitively coupled through the glass, including a glowing light within the tube, and inducing a mild electrical current. At the time, I accepted the idea that this was, indeed, an example of a "quack medical device". In 1996, I began work at a Vancouver Washington contract-electronic-design/manufacturer firm. One of the major products that this company made were "TENS" devices. (Transcutaneous Electrical Nerve Stimulators [3]http://www.tensunits.com/ ). They were/are intended to reduce chronic pain. They worked in pretty much the same way that those "quack" early 1900's devices worked: Cause a AC small current to flow within flesh. What was thought to be 'quack' in 1978, turned out to not be 'quack' at all!
