So, the gain of function with the Chyna dust is exactly this, the admixture of various toxins and pathogens to kill people asap. This dust expands in water very easily when fresh, if it didn't, they couldn't spray it. But once it hardens it becomes almost impervious and will bind to even to concrete, imagine what that does to a person internally? I am positive that they use some type of self-replicating biological such as larva or worm like material which will self-heal, colonize, and help borough into living tissue alongside the properties of cyanide as I have seen actual larva in a puddle of chemicals in my driveway where there are no trees. Remember, admixture. Radiation is a whole other topic and can be just as lethal but in combination it is used as a catalyst to speed up the process of termination.
