Yeah, I realized that after I posted. I ended up sending a link to a physical chemist who might be in a better position to theorize on the subject than I am.

I don't know for sure if this video is of the experiment done in a vacuum, but they did perform this in a vacuum as well and the grouping still occurs.

Seems that they repeated the experiment at low air pressure and humidities and found that while humidity plays an important role in sand droplet formation, air pressure does not.

Air resistance? I wonder if it would act the same in a vacuum.
Now maybe I'll go RTFA...

this is demonstrating the gravitational pull of planets in space. what i dont get is some of the very small particles flew past the large clusters.. I dont think this correctly demonstrates what it is trying to.
