About magnetism:
I know how magnetic hard-disks work, and other stuff related to magnetism.
Magnetism does go through layers of paper and tin-foil. But they never test that.
It always looks like sticky skin.
And because there is usually a fever, I can imagine that the skin becomes far more sweaty.
To make something magnetic you need to put nails or similar in an arm.
Which some Russians(?) probably did in one video.

The graphene stuff is new technology.
Graphene are threats of graphite that can be used for a lot of things.
So there are many patents about possible stuff that they can make with it,
They can stick stuff on it, use it as a wire, or make rockets or glass.
But it is 80 years behind our silicon technology, and it has some long-term toxic side-effects.

Because of the strings you can make good filters with it.
And I think that Spanish researchers may have found a few threads from a graphene filter in a vaccine sample.
But I find it more probable that they found some unidentified biological materials instead.

Researchers are working out if they can make interfaces with cells, to insert chemicals by using it as a carrier.
Or to connect electrically by using it as a wire.
So these are technologies for use in controlled laboratory studies, not something that is spread randomly on a gigantic scale.

So combining all these different things, some people claimed that we may have
graphene nano-bot technology injections that react to 5G.
And one claimed that the injections were 99% graphene.
And this is all confusion that is unfounded, and probably injected into the conspiracy crowd to keep us busy, while they inject the children with an experimental killer mRNA.
