Details of blackening agent operation:
The goal was to turn the office into a solar cooker so that when Chris opened his office door on Monday morning he would be hit by a blast of hot air. We were concerned that when the office became very hot, the four or so computers in the office might overheat and become damaged. To prevent this we shut down the computers. We couldn't do so gracefully because we didn't know Chris's passwords to be able to log in to Windows to issue the shutdown command so we simply cut the power. We figured that Chris would have saved his work because of the possibility of a (non-conspiratorial) power failure and if he hadn't, oh, well. We left his monitors turned on in the hope that their heat-generating capability would help to make Chris's office a combination solar/electric oven. We also knew that the extra heat might cause some building air conditioning equipment somewhere to work harder than it otherwise might and we only hoped that the air conditioning would be overwhelmed.
The following day, Chris emailed the Furniture and Facilities Department and said that his windows were dirty and he wanted to have them cleaned. FurnFac replied and said that they would have a time estimate once they investigated and determined what the "blackening agent" was on his windows.
