I've come across hundreds of these videos, I never pay any attention to them. I've heard of Martin, not come across the channel. Will look into it, thanks.
An aside I see on that channel, the MH370 videos, what do you think about that whole thing?
Seems there are many videos around of people making these thing, I'm trying to find videos that conclusively debunk this.
It's curious. I don't see any hidden cables, induction chargers or anything below a table when these are running outdoors. None of the typical tricks I would expect to see. My default position is that these are faked, but I can't see the obvious means for how they are doing it.
