Divining Rod/Water Witching...is it real?

Yes, divining water is very real. In my experience, most water witches do not use rods; they use pendulums. For those who use birch, they are not really rods. They are whips cut from new tip growth, and they have to still be living, for birch has an affinity for water. It will move towards water like a magnet moves towards steel.
