What are some easy science experiments anyone can perform to prove the earth is not flat?

also post yfw someone says the earth is flat

Buy a plane tickets all the way around and look for the edge.

Eratosthenes figured it out in the bronze age using some shadows and highschool math.
Anyone who identifies as a flat earther is either being ironic, or willfully ignorant and too stupid to reason with. Either way it is a waste of your time to engage them.

This may seem too advanced to your 12-year old friend. But how about taking a photograph from somewhere out a good distance from the Earth?

Get two long poles, a buddy, a couple tape measures, synchronized clocks, and some cars.

Go to a big ass field (they did this in a desert). Plant one rod in the earth and have your buddy drive longitudinally a good number of miles away and plant their own rod. Record the length of the shadows throughout the day and at what time the shadow is superimposed over the rod (midday). You can use this to calculate the circumference of the earth to a pretty high degree of accuracy if you have a big enough rod and do it right.

Eratosthenes Experiment is the name. google is your friend.

The other method involves a tall sailboat and a spyglass. Watch the sailboat go over the horizon with the spyglass and you will see the bottom disappear before the top. In a flat earth both would slowly disappear at the same time when the limit that light can travel is reached. But on a round earth the bottom will disappear before the top does.

Mike Hughes tried that and look at where it got him. (They) will stop at nothing to hide the truth.

The shadow idea is a good one. Things like the sailboat are easier for the retards to understand though.

well let me explain smarty pants try going to any of earth's poles okay?? think.. now if you fall from iceberg then you reached the edge of earth
simple as that I prroved round earthers WRONG!

The Earth is flat on an infinitely repeating plane. Next.

>>11640540
Actually anon, the earth may not be round, but isn't a plane. It's a cube. The top and bottom face repeat (where we are) but the middle faces are the arctic.

What do these dopes think meteorites are? Bits falling off the ceiling? lmao
