Its nonsence. Scientific quackery. You cant have a powder consisting of single, separate atoms. All atoms are joined to many other atoms. Ive hear real scientists say that a single, detatched atom cant even be observed on its own if it is separated from other atoms, let alone be manipulated or changed. This is because, in order to even observe a single, separate atom, you would have to focus at least one photon of light or other radiation on it, and that photon is moving at the speed of light and would knock the atom miles away before you could ever hope to observe it as a single, detatched entity.
