Scrying foretell the future using a crystal ball or other reflective object or surface.
To scry using a pendulum, you hold the small end in your hand, remaining very still, and ask a yes or no question. If the pendulum moves in a circle, the answer is yes, and if it moves from side to side, then the answer is no. This is a very basic explanation, but let your intuition guide you. When asking questions, try holding the Pendulum over your favourite stone or crystal for clearer answers.
