Goldfield Hotel - Flying brick or flying schtick?

Yes, I am as much as sucker as the next person in watching ghost TV shows. Last fall I tuned in to Ghost Adventures because they were visiting one of my favorite scary places - The Goldfield Hotel (click here for story) and while I can't vouch for the lead investigator (I love it when a man runs and screams like a wee girl - does a lot for ratings), I still can't figure out the brick. The rest of the show had some great footage, watch for reruns! :)

Look closely for the flying brick. Is it real or movie magic?
