I did a little clean up in the studio a few minutes ago. In order to cover the hole in the ceiling, I decided that the expedient thing to do was to grab the can of spray-on glue and put the foam back along the edge of the ceiling where it had started out the evening. Of course, you don't want to get the glue onto the carpet, so I took it into the laundry room, where the floor is still concrete. I sprayed the foam with the glue, then took it back and stuck it in place. Success!
And then I heard a really loud annoying beeping. The gas detector in the laundry room is greatly offended by the propellant that the spray-on glue uses. I've reset it a couple of times, but it's started beeping again. Audibly. In my second floor office. *sigh*
I guess I'll go down and pull the battery.
