Why Cruise Ships Don't Tip Over | If You've Ever Wondered
From the front, a cruise ship looks like an apartment building with waterslides. Put that on moving water and surely one good shove should tip it over. So why doesn't it? In this animated explainer, we look inside a giant cruise ship to see where its weight really sits, then slice it in half to watch the physics at work. When a wave makes the ship lean, the underwater shape of the hull changes, the buoyant force shifts, and gravity and buoyancy team up to push the ship back upright. We also look at stabilizer fins, ballast tanks, why sloshing water is dangerous, and why even a well-designed ship isn't invincible.
