Charlie Charlie Challenge: Strange ritual claims to summon Mexican demon

A new Twitter craze is scaring up lots of screams.

It's called the 'Charlie Charlie Challenge' and has kids everywhere trying to summon a Mexican demon.

The ritual involves putting two pencils on a piece of paper in the shape of a cross.

The participants write the words 'yes' and 'no' inside the four squares outlined by the pencils.

Those who dare to try the challenge then say 'Charlie, Charlie Are You Here?'

Some who try the challenge say the pencils move and are sometimes accompanied strange occurrences like screams and broken mirrors.
