If you've ever watched TV shows like 'Long Island Medium,' you've seen the stunned looks on people's faces when the psychics start to get positive "hits." The guy in the video above amazes strangers with specific information, but there's one catch: he's not even a little bit psychic.

Jack Vale is an online filmmaker and comedian (again, not a psychic), but by harnessing the power of social media, specifically Instagram, he freaked these strangers out with personal specifics.

The lesson from this experiment? Be careful what you share on your social media postings—you never know who might be looking at them!
