How it's used
Originating from the historical street performances of Western optical devices, this idiom carries a sense of exposing a calculated deception or a staged performance. It is most effective when describing elaborate schemes or long-running lies rather than simple mistakes. Using this phrase adds a dramatic flair to your speech, implying that the person being exposed was putting on a show.
Examples
His scam was uncovered by people very quickly.
You think you can fool me? I saw through your trick a long time ago.

Common mistake
Learners often mistake this for a literal description of breaking an object, but it is strictly metaphorical. It cannot be used to describe simply finding a hidden item or discovering a secret that was not part of a deliberate, deceptive act.
