Ever been on a cruise ship? It’s a floating city with 5,000 people, 3,000 bathrooms, and one plumbing system that’s basically a teenager running a sieve. These ships have miles of pipes that sit in saltwater. Saltwater eats metal like candy. The result? Toilets that flush backward. I’m not joking. On some ships, the water in your sink can taste like yesterday’s soup. And because the pipes are all interconnected, a single clog in the engine room can send a geyser of... well, aromatic water into the karaoke lounge.
Fun fact: Cruise ship toilets use vacuum suction, not gravity. So when a pipe bursts, it doesn’t leak—it erupts. One captain called it “a chocolate fountain of chaos.”
