There's a guy going around adding magic smoke into the dangly white tech hanging off the ceiling with some kind of suction cup on a stick instrument.
They - they run out of magic smoke after a while?
It's not a sprinkler head or a loudspeaker, because I'm looking at those and it ain't them. It's not an air conditioning duct. I guess it could be some kind of alarm thing. What kind of alarm thing requires adding magic smoke to it?
