> Cotton reacts to static electricity
That's false.
>In the past, the majority of protective clothing used in the field of ESD was 100% cotton. As with all natural fibres, this offers the advantage of being subject to only minimal antistatic build-up without the use of additional equipment.
Cotton is specifically used because of its non-static quality. This shows the pcr swab material is definitely not cotton.
> the human brain is basically a battery
You just revealed yourself. Static charge as nothing to do with "batteries" nor is the brain a battery.
