What's the thing with Charlie Charlie challenge?

Y'all know the viral trend that got spread all over social medias on Tuesday,making it onto articles by MTV,Metro.co.uk,The Independent,aaaaaaaaaand - the cure has been found.

Apparently,the mystery after all this lies in the depth of the human evolution history. But no seriously,it has to do with gravity.
In an article by The Independent,it is said that:

 The Charlie Charlie Challenge — or variants of it, known as the pencil game or Charlie pencil — has been around for some time. It’s claimed that the game is an old Mexican tradition, but there’s no trace of that on the internet, but it seems to have been around for years before it took off this week.To play the game, grab a sheet of paper and draw two lines on it to make a cross. Put a “yes” in the top right and bottom left hand corner, and a “no” in the remaining two.

Yes,we kinda knew that.Minus points to whoever wrote that article.

But why are there pencils moving? - The same source,actually gave a good explanation to that.

Gravity, and the awkward positioning of some pencils. They just wouldn't sit still even if you wanted them to.
It’s perhaps scarier than a Ouija board because it doesn’t have the same explanations. With those boards, players have to keep hold of a glass while it moves around the table — so it’s not difficult to imagine that people might be pushing it around without knowing it.
With the Charlie Charlie game, however, nobody is actually touching the pencils. But they are still likely being pushed — the pencils have to be so finely balanced on top of each other that even the slightest movement from a breath or slightly tilted surface will push it around.

Hmm,interesting.Add points to the author.

Why does scary stuff happen afterwards?

It’s possible that strange things are happening. But it’s equally likely that after playing the game the brain gets itself into a state that makes it extra suggestible and fearful.
That’s the same thing that makes people more likely to hear strange noises when they’re on their own or in the dark. In both of those situations, people are genuinely more in danger — so the brain think itself into a special fight or flight state that makes it extra-vigilant to noises, so that those dangers can be avoided.

However,in the midst of all this drama,you,children of Twitter can continue being dramatic as hell,and just a reminder:The reason you are failing the exams is not the Charlie curse,but it's you the one not studying at all.
