Welcome, novice diver, to the sink hazard course! Today, you'll be learning about the most basic, yet most treacherous, of sink hazards: The Unseen Sink.

The Unseen Sink is a mysterious, shape-shifting sink that appears to defy all logic and reason. It's as if the laws of physics don't apply to this sink at all, and you'll be left wondering if what you're experiencing is even real.

To navigate the Unseen Sink, you'll need to understand the art of Sink-Fu, a mystical technique that involves a series of cryptic gestures and a deep understanding of quantum mechanics.
