I don’t think you are on the right path at all. Like another user said. There’s no telling if that video is genuine or not. It looks fake to me. Like you edited it to make the device disappear. There’s no such thing as a device just disappearing on its own. Anybody could post a YouTube video like that. I simply do not believe you.
It's like this with most paranormal things. You need to witness something first-hand it's just human nature.
