I have pondered on this for at least over a decade. I am beginning to think it is for Project Bluebeam. I think it is possibly for holographic projections. I know it sounds wild but there is a lot of information out there about that topic that leads me to ponder on this. I think the aerosols with heavy metals in it creates a platform for holographic images to "stick" like a "screen" so to speak. The Bible does warn not to be deceived. I think there is a grand deception that is brewing and Project bluebeam is def a part of it.
