3) There is no consensus as to why dowsing rods move.
The experiment was designed to investigate how dowsing rods move with changes in electrical conductivity.
In the first phase of the investigation we found that dowsing rods moved in a predictable pattern.
Why dowsing rods move has been attributed to everything from psychic powers to natural physical forces.
It is difficult to generate serious investigations into why (or if) dowsing rods actually move.
The dowsing rods align themselves perpendicular to the equipotential surface.
The dowsing rods respond to any large change in conductivity be it buried metallic objects, resistive ceramics and plastics or natural features.
Hand-held dowsing rods have applications beyond looking for potable water.
