Pendulums are used to answer yes or no questions, among other things. Hold it in your hand, and focus on your question. The pendulum will swing right or left for yes or no. It may depend on the person whether right or left is yes or no, so start first with a question you know the answer to. This may be, "is my name --?".
Pendulum colors and stones vary.
