The pendulum is a simple device, consisting of a weight attached to a chain or thread. The pendulum reads energy patterns and is able to extract information from deep inside our subconscious minds. Wands are symbolic for the element of Air, though in some traditions it symbolises Fire. It can be made from any material, including wood, metal and rock and Wiccan wands are sometimes set with gemstones or crystals. A wand is used to direct psychic energies to perform a certain action.
