The hazardous air we are breathing in the NE these last few days is much different than the last round a few weeks ago. The air smells like chemicals/ burning plastic this time, not burning wood. It is giving people I know sore throats and the slight feeling of nausea. I talked to a few customers at work in the upper Midwest and Mid Atlantic and they are smelling the same thing.

High particulates in the air create much better conditions for hologram projection.
