Okay, I saw a video of the "disappearing" casing. They don't disappear. It's a cherry picked part of the video that is rather low quality. In other parts of the video you can see the casings on the floor, and they remain after he leaves and comes back into the building. I think most of your issue with the video is due to the extremely low quality causing things to appear as they are not.
You see nothing unusual with this behavior?
Did you think the video of the disappearing shells was unconvincing also?

I didn't say it wasn't unusual. But that doesn't disprove anything. I'm not familiar with the video you're referencing.
