A robot made of magnetic slime inside your body.

The slime, which can be controlled by a magnetic field, can move in confined spaces and grasp objects, making it ideal for possible use inside your body.

Li Zhang of the Chinese University of Hong Kong and his colleagues mixed neodymium magnet particles with borax (sodium salt of boric acid), a common household detergent, and polyvinyl alcohol to form a slime that can be controlled.

Obviously, it is time for some people to take a more serious and thorough look at the reports of graphene in some vaccines and its effects on the human body. As you can see, anything is possible and realistic.
