This prank may make you think again before you post

These days we tend to tweet, instagram and facebook the things that happen during the course of our day.

Well, after seeing this prank from America you may rethink what you post on social media.

Jack Vale plays a mentalist with unsuspecting members of the public who are totally freaked out by the private information he seems to know about them.

Little do they realise what he knows is free to access to anyone that uses the internet.

Maybe time to look at those privacy settings people!
