Side by side test of flat earth vs globe model at a state park near Tulsa

A buddy of mine is deep into flat earth theory. He kept going on about how you can see too far on a clear day for the globe to be real. So I drove us out to Keystone Lake last Saturday with a cheap telescope. We set up on a hill and looked at a water tower about 9 miles away. According to his math, the bottom 15 feet should have been hidden by curvature. We could see the whole tower right down to the base. He got real quiet. I didn't say much, just packed up the scope. Has anyone else ever done a real world test like that and changed someone's mind even a little?

oh man I saw a video on youtube last week that was exactly about this. Some surveyor guy did a test across a lake and he kept saying how the math for curvature just doesn't match what you actually see. I mean I'm not gonna pretend I understand all the formulas but it stuck with me because he showed his work and everything. The thing about those flat earth tests is you gotta be super careful about refraction and how light bends through different air temperatures. Like on a hot day over water that mirage effect can make things visible that should be hidden. But your buddy's water tower test sounds pretty solid if you both confirmed the distance and height. I've never actually done one myself but I've read enough to know that people on both sides cherry pick their evidence real bad. It's kind of refreshing to hear someone actually went out and tried to prove their friend wrong in a real way instead of just arguing online.

Did you ever catch that old YouTube video where a guy filmed a ship disappearing hull first over the horizon?
