These 'water witches', draped in dubious pseudoscience or self-assembled mythologies—or both—typically use divining rods and some sort of practiced intuition to "find" water. The professional variety do so for a fee. And business is booming. They're just part of a storied tradition of pseudoscientific hucksters exploiting our thirst for water, with everything from cloudbusters to rainmachines to New Age rituals."
