A dowsing rod is a tool traditionally used by diviners or water dowsers to locate underground water sources, minerals, or other hidden objects. It typically consists of a Y-shaped or L-shaped rod, often made of metal or wood, held by the dowser in both hands. The dowser walks slowly over the desired area while holding the rod lightly, waiting for it to respond by twitching, rotating, or pointing downward when passing over the target. This ancient practice combines elements of intuition, physics, and belief in unseen energies to guide the dowser towards their sought-after objective.
