Those Nanobots from Chemtrail cannot move themselves. But they can be manipulated by 5G tower electromagnetic field. Once those Nanobots are inside your body, they can manipulate them by using the electromagnetic force from 5G towers.
How Nanobots can kill us? I don’t know exactly. But the following video can explain how they can manipulate those Nanobots in your body to damage your organs.
Nanobots can be in our foods, too. What I know is Titanium Dioxide (Nanoparticles) is used for verity of foods. I will explain this in another article.
