Hi Carol, thanks for your input, I truly appreciate it. I did in fact watch the YouTube video. I was rather skeptical at first, but as the video went on I warmed up a great deal to your abilities. What I found most intriguing was that the pendulum reacted immediately when the answer to your question changed. When the answer was yes, the pendulum did its thing, but when the answer was something else, the pendulum did not wobble and rotate in confused circles for a few seconds as I thought it would, naturally transitioning from one swing direction to another, but it just changed direction with a snap like someone was holding the weight. Very, very intriguing.
