Where does the cellulose come from? Is it just ambient particles or are they emitted from the machine? Where does it go?

The cellulose comes from the black liquor on a spoon (see 0:46 in the video). The put the spoon at the focus of the laser and with luck some particles get confined. After the trap is lost, the particle just sort of drifts away in the air, since they are only tens of microns.
