Charlie Charlie challenge

The Charlie Charlie Challenge is a game that some people play. Players make a kind of fortune-telling apparatus with two pencils laid across a piece of paper. People will then ask out loud the question, "Charlie, Charlie, are you there?", and wait for an answer. Some people believe that spiritual entities will answer the question "yes" or "no" by moving one of the pencils. There is no real evidence that this game works and it is just for fun.
