'Red Lights' clip shows supernatural debunkers Sigourney Weaver, Cillian Murphy tipping tables

The paranormal thriller Red Lights starring Sigourney Weaver and Cillian Murphy as scientists who set out to debunk phenomena - including the antics of Robert De Niro's celebrity psychic - opens on July 13. Directed by Rodrigo Cortes (Buried), the film is unleashing a series of clips, such as the one that debuted on EW today.

Unfortunately, EW does not allow embedding of the clip, but in it, we see Weaver explaining to a room of students how mediums can fake a table tipping - with Murphy performing the action. It's a pretty cool clip from a flick that has us intrigued.

Now go check out the clip and then begin practicing your own paranormal fraud!
