Magic?

Magic? Tricks? Fakes? Sometimes I wonder what it is with "Illusions" that fascinates so many people. I found this "Viral" video from Samsung that has a camera trick in it. I've watched it, watched it, and watched and still can't figure it out or don't want to figure it out. I've read the comments below and watched for them in the video, but I just don't see what others do.

Watched this video and tell me:
How do you think they pulled this trick off?
