When I read the the title to this video, I imagined the scene from Resident Evil when they get stuck in the elevator that you can see here (warning for graphic content).  I was happily surprised that that was not the case for this video but was still creeped out. 

Magician, Andy Gross has developed a magic trick/ prank that is known as SplitMan.  He starts as a normal standing human being and then halfs himself.  That is were everything gets weird.  If you are like me, you try to see behind the trick and figure out how this trick works.  I watched this video several time before posting and I still can't grasp how this works.  I guess that's what makes a great magic trick.

I do know one thing, I never want to run into this in real life.
