Heard a guy at the diner break down the 'flat earth' thing in a way that actually made sense

I was grabbing a coffee at Lou's Diner in Akron and overheard two guys at the next booth. One was going on about how the horizon always rises to eye level, which he said you can test yourself. He pulled out his phone and showed a video of a simple experiment with a level on a lake. It wasn't about secret societies or NASA lies, just a basic observation anyone could check. I always wrote that whole idea off as crazy, but hearing it put that plainly, as a physical thing to look at, got me thinking about how we dismiss stuff without looking. Has anyone else actually tried one of those basic horizon checks?

That lake level trick is a classic optical illusion. Water isn't perfectly flat, it curves with the land. A spirit level on a small scale can't measure the planet's curve. You need to look at ships disappearing hull-first over the horizon, or how we see different stars in different places. Those are the real checks. Doesn't it seem more likely that a local effect on a lake is tricking our eyes?

You know, @charles_price, I used to believe the lake thing too until I saw a boat vanish bottom-first.
