First of all, I learned a new thing from your reply, but I don't really mean that the whole ceiling was dropping down powder. There was just a small spot that was doing that, and the whole thing was happening because someone was jumping up and down onto the floor right above the spot. And the powder was really more like a dust of white substance, which is usually put on ceilings.
