I'm in china right now and youtube is banned
So I can't really check what these people are doing.
We used to lift each other -above our shoulders-
-WITHOUT- feeling any pressure on our fingers.
As soon as everyone would open their eyes, the person
would suddenly become heavy and fall.
Question: What caused the sudden change in weight?
Have you consider that your perception might be fallible?
Have you ever been to a magic show and seen a professional magician vanish something? Just because it looked like something vanished, doesn't mean that is the case.
Similarly, have you never experienced optical illusions (one category of perceptual illusions)? Some of them can be astounding. In this one, for example, purple dots seem to vanish--gobbled up by a green dot. In fact, the purple dots never vanish, and there is no green dot at all!
So you are concluding prematurely that there was a change in weight.
What would you need to do to reach the conclusion validly that a person's weight is changing?
