Spoiler: Case 3
When asked how the Disappearing Badger trick was done, turning off the lights is the wrong answer and gets you penalized. The problem is... that's EXACTLY how tricks like this get done in the real world! The counterargument ("you wouldn't be able to see anything") ignores the real possibility that a gradual dimming of the lights in one or another segment of the corridor could produce a very convincing disappearance - especially if one section of the broken mirror had no backing on it, and was semitransparent.
In contrast, moving a giant mirror silently and effectively is likely to fail, and more inconsistent with the blueprints than a very small mirror chamber with a badger doll in a strategic location. Furthermore, unless the audience's attention were diverted when the mirror moved, they wouldn't see a gradually disappearing badger... they'd see a moving hallway! Isn't it kind of obvious when a mirror moves in front of you?
Here's a Wikipedia page on the light-based effect, which is used in theme parks: Pepper's Ghost.
What makes this extra groanworthy is that the case would have worked just as well using the Pepper's Ghost trick, which also frequently involves a hidden chamber behind the mirror.
