Being a truck driver. I've had a few interesting experiences with my pendulum. For example today while driving in VA. It was rather windy. As usual while driving I have at least one session while driving. Being as windy as it was. When I took my pendulum out of the bag. It wouldn't even move. So I asked it. Which has more power the vibrations of the wind. Or energy vibration. The pendulum started to move back and forth with a high rate of speed.
