The Charlie Charlie Challenge has now grown into an internationally famous fad that a lot of teens, and even kids, have tried. Apparently, this latest Twitter craze is a Ouija-inspired game that allows players to get in touch with a Mexican demon named Charlie, and ask him about anything they want.

Although it looks relatively simple, it is supposedly an “ancient Mexican tradition.” Players will have to set up two pencils on a piece of paper, where their question has already been written. The pencils are arranged in the shape of a cross, and the words “yes” and “no,” or any other word choices that the players would like, must be written inside the four squares that were formed by the pencils, according to Mirror.

To start the “ritual,” all of the participants must repeat the words, “Charlie, Charlie, are you here?” When the pencil suddenly takes direction, presumably, all by itself, and points to “yes,” that means Charlie answered their call and is already in their presence. Then, players can start to ask him for guidance or advice in the form of “yes” or “no” questions.

Some videos have been posted on Twitter, showing some young teens playing the Charlie Charlie Challenge. The pencils, as expected, moved, which, in turn, freaked them out and caused them to run and tumble over each other. This latest Twitter craze might be funny for some, but others have insisted to hearing voices and seeing shadows after they tried it.

“Some kids have talked about strange things happening after playing this game – like seeing shadows or hearing a child’s laughter,” Pencils.com stated. “Others did not experience anything at all.”

To properly end the conversation with Demon Charlie, the participants must ask him politely. Everyone must chant “Charlie, Charlie, can we stop?” Afterwards, everyone must wait for the pencil to point to “yes” before they can actually leave. Leaving with the question unanswered or with the pencil pointing towards “no” could leave a portal open for other demons to enter through, supposedly.

The Smithsonian Magazine, in 2013, discussed the Ouija board and its effects to society. Since the Charlie Charlie Challenge is in a way, similar to how the device is being played, a few points discussed in the report might shed more light on the topic. According to Professor Chris French, the so-called talking board is nothing but a fad. “It can generate a very strong impression that the movement is being caused by some outside agency,” French reiterated. “But, it is not. It is usually a group of people. Everyone has a slight influence. Once the idea has been implanted there, there is almost a readiness to happen.”
