I would disagree. I feel sure that 99.32% of the population can dowse.
Forked sticks will not work for dowsing when trying to find polar liquids such as water, and it is an act of purest hubris, not to mention dangerous, to have tried to do so.
A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically.
Water (H2O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out resulting in a net dipole.
Since a forked stick is bipolar, it is suitable only for finding non polar substances. A molecule may be non polar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule.
Forked sticks could cause the dipole to cancel and explode. When talking to forked sticks, always inquire about safety.
The
boron trifluoride molecule (BF3) has a trigonal planar arrangement of three polar bonds at 120°, and is non polar. This results in no overall dipole in the molecule, and it is safe for use with forked sticks. I have found many gallons of boron trifluoride on my farm using willow sticks. Use oak for finding radioactive elements or stray gerbils.
Coat hanger wire is tuned to the frequencies of humans' cognitive awareness syndromes, and the quantum efficiency is increased by rubbing with empathetic dowsing grease. Plastic coat hangers will not work, of course, because they do not retain the memory of having had human clothing on them and as a result will not recognize the voices.
The dowsing range of #12 black coat hanger wire is about 3.2 miles (5.15 km), and the smaller the gauge, the greater the distance of detection, much like homeopathic theory predicts. I once found a German submarine using .002" platinum wires. My wife wouldn't let me keep it.
Finding lost dogs is best done with forked beef bones.
