About the pendulum

An experienced pendulum can tie anything to a rope to make a pendulum, but I suggest that it is easier for you to master a professional pendulum than for a novice. If it is inconvenient for you to buy a special pendulum, I still recommend an irregular, asymmetrical and generally parallelogram crystal necklace pendant. After all, it is crystal, which is easier to operate than porcelain. If it is convenient for you to buy it, it depends on your hobby. The pendulum usually uses the right eye.
