On Tuesday night ( 29th October) I crept around the science building and placed red wax keys on the doors of many of the staff offices. For Wednesday, 30th of October the door was locked and 72 red keys were hung across campus.
The next morning - to my delight some of the staff were attempting to use their keys to open the locked door. Some left their attempted keys on the door knob.
And the door, AG12, got it's own key too.
