Flat-Earthers planning expedition to Antarctica.

5. Oh, you missed the best part at the end.

There was a bit about their decision to do an experiment comparing light beams with the Earth's surface, to prove the flatness. ( Actually, this is somewhat like some of the experiments done by Ancient Greeks, which showed that the Earth is a sphere and actually allowed the Ancient Greeks to calculate the circumference of the Earth with stunningly close accuracy.) Anyway, after a minute, we could hear one of the experimenters phoning his distant cohort to tell him, "You need to raise your light; we can't see it from here."
