A pendulum is a necklace that can be made or bought. They are only able to answer yes and no questions, and you dont choose the pendulum it chooses you. If it dosent work for you right away then the longer you wear it the more it will bond to you. Of it does work for you then you can ask it any yes or no question, first you must say "can you spin for me?" If it spins in a circle (you must have your hand completely steady and still) then it is ready to answer a question. It will also protect you from danger, you will not have to activate it, it will work on it's own. For more info you can look on Google. You can also make a pendulum board to determine which way is yes and which way is no.
