We believe that animal navigation is based on Quantum effects which are inimical to a classic Newtonian science based approach. This world is so weird and unlikely that it is impossible to understand properly or as Feynman said if you think you understand it you must have misunderstood. Dowsers know that you can access this…
Try this experiment – Use dowsing to find direction and distance
First, you will need to make your tool: a Dowsing Rod. Take a wire coat hanger. Cut one of the diagonal bars going up to the hook. Cut this with pliers about 6” (15cm) from the corner to the horizontal bar (which you use to hang your clothes). Now cut the horizontal bar near the…
