Our library has a foyer with two sets of automatic doors. Even though the wind rarely blows from north to south at our location, it creates a problem when it does. Some gusts are stong enough to activate the first set of automatic doors. This would be fine if the wind would activate the second set of doors, but most gusts don’t. When this happens, the air blows straight up into the ceiling tiles, throwing them around like old scraps of paper. Most of the time, the tiles will fall 20 or so feet to the floor, but this time, the tile remained suspended in the air by a wire leading from a smoke detector.
You can’t really see the wire unless you’re sitting at the circulation desk, so I’d just as soon put up a sign to tell patrons we have an anti-gravity exhibit on display for the time being.
