Quartz Double Ended Pendulum.
Pendulums are used for divination. They are very accurate when used correctly. Be clear to state a precise question which can only have a ‘yes’, ‘no’ or ‘neutral’ response. It will swing in either vertical or horizontal lines, or have a circular motion. Try asking it ‘test’ questions in your head to see which kind of motion response it will give for each correct ‘yes’, ‘no’ or ‘neutral’ answer.
