In what some people are seeing as Black Bubbles:
Hydrogel was based upon the black-goo, a DARPA concoction. The Black Bubbles are NanoCages. NanoCages are what I have been calling for 2.5 years NanoSynBio with a hollow belly for payload. Technically, NanoCages are various drug-carriers have been developed, including DNA, proteins, liposomes and several other polymer cages, consisting of many well established natural and synthetic nano-particles. All these drug-carriers can self-assemble in the body and can be manipulated (via Ph, frequency, and magnetism) for delivery into target tissues.
Ponder the word Cages in the Scripture: As a cage is full of birds, so are their houses full of deceit: therefore they are become great, and waxen rich. Jer 5:27
They imprisoned him in a cage with hooks and brought him to the king of Babel. Then they placed him in their dungeon where his voice would no longer be heard on the mountains of Israel. Ezek 19:9
I will attack them like a bear robbed of her cubs and tear open the rib cage over their hearts. I will devour them there like a lioness, like a wild beast that would rip them open. Hos 13:8
And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird. Rev 18:2
