Flat Earther unintentionally proves that the Earth is round during own personal experiment

If there's one thing that Flat Earther's seem to love, it's proving themselves wrong.

While the idea of a flat Earth versus a spherical Earth goes all the way back to Greek philosophers like Pythagoras and Aristotle, you'd think that modern technology would make it pretty easy to prove that the Earth isn't flat.

Despite flat Earthers standing by their beliefs, there's an increasing number of cases where they prove that the Earth is round simply by trying to prove that it's flat.

Up there with conspiracy theories about Moon landings, Roswell, and chemtrailsm, at least flat Earthers stick to their guns in the face of mounting evidence to the contrary.

Jeran Campanella might've accidentally blown the lid off flat Earth theories during 2017's Flat Earth International Conference (yes, it's real), held in Raleigh, North Carolina.

While here, Campanella tried to prove the existence of a flat Earth by conducting an experiment with two sheets of styrofoam and a light source.

Placing two boards at the same hight and slightly apart from each other, Campanella carved a hole in both of them and measured it at 17ft above water level.

Placing a camera in front of the first hole, Campanella got someone else to stand behind the other board and shine a light source through the opening.

Campanella explained: "If you're seeing through this hole, through the next hole and seeing the light at the backboard or at 17 feet off the water the Earth is flat.

"If he's holding it up at 23 feet high and we're seeing the light well that's because the Earth's curved. So I should only be able to see it when it's at 17ft."

When looking through the camera when the light is held at 17ft, Campanella was only greeted by darkness. When the light was lifted over their head, it then became visible. A defeated Campanella simply said: "That's interesting."

Who'd have guessed that the Earth is actually round instead of flat?

Campanella was cooked in the comments on YouTube, with someone saying: "'That's interesting' is a weird way of saying 'I was f**king wrong.'"

Another chuckled: "Ladies and Gentlemen, this is what those of us in the business call a 'bruh moment.'"

This wasn't Campanella's only try, as someone else pointed out: "This was actually the second experiment. For the first these geniuses spent $20,000 dollars on a measuring instrument that proved them wrong. They wouldn't accept the results so they did this experiment next. Probably should have done this experiment first and save themselves $20k."

We're reminded of when flat Earther Dave Weiss was left similarly speechless when someone used a simple analogy to prove the Earth is round. Still, Campanella's blunder was so infamous, it was even featured in Netflix's 2018 documentary, Behind the Curve.
