I challenged a flat earther friend to build an accurate sundial. He got flustered and I told him just do a bit of research and it's simple. Then he got pissed off. His mind couldn't take the implications. A sundial proves earth curvature. Even two sticks stuck in the dirt at the same longitude several thousand miles apart bears this out. Thats how the size of the earth was discovered. Ballistics also demonstrated free fall and are used in aerospace. Ballistic principles were discovered soon as a European scholar got curious and did the math after playing with a musket. The stupidity of those who espouse the idea of a flat earth is jaw dropping.
