It is a simple tool used for communicating and gaining guidance from the spiritual world. This is one of the easiest methods of divination. When used for divination the pendulum acts as an antenna that amplifies signals or energy vibrations emanating from a spiritual guide or the Divine energies you've called upon. These vibrations focus their attention on the pendulum and cause it to move in specific directions, giving you answers and guidance to the questions you put to the tool.
A pendulum is simply a string or chain, weighted by a pointed crystal or some other form of heavy object called a "bob". In my personal experience, I've had better results from natural materials, such as crystals, and varying forms of metal, silver, gold and so on.
