Dowsing

Dowsing, sometimes called divining, (when searching specifically for water) water finding or water witching, is a practice that attempts to locate hidden water wells, buried metals or ores, gemstones, or other objects as well as currents of earth radiation without the use of scientific apparatus. A Y- or L-shaped twig or rod is sometimes used during dowsing, although some dowsers use other equipment or no equipment at all.

Dowsing has been in use since ancient times and is still widely practiced although the scientific evidence for its efficiency is disputed. In the 1980s German physicists undertook a large experimental study of dowsing and concluded that a "real core of dowser-phenomena can be regarded as empirically proven", while physiologist J. T. Enright wrote that those same experiments provided "the most convincing disproof imaginable that dowsers can do what they claim."(BUT WE CAN).
