You made this in 5 days? That is mad! I love it!

You can just reason yourself to a conclusion. No need for experiments. All relevant laws of physics would suggest it is a sphere, your own eyesight and day to day experience is congruent with a sphere, the sun and moon (and other clearly visible planets/stars ) are obviously spheres as determined by looking at them. Unless you want to argue that they are flat as well, coincidentally all facing with their circular shape towards the earth (zero chance), or you want to argue that Earth is the only body in the universe that has a distinctly different shape than all the others (zero chance). Also, to explain a topological disk, the trajectories of planes and boats flying/sailing across the world would have to be completely different, distances wpuld we warped, which does not match reality. These 10 lines in itself and a little bit of thinking what they imply should be enough to make a 'flat earth' highly unlikely. I am very curious on some geographical and mostly physical models that would correctly predict behaviour in a flat earts scenario that would be in line with observations: gravity (on Earth and between heavenly bodies), trajectories of objects, maps with correct distances, etc

A flat earth is so easily disproven, or at least made highly unlikely. If you even consider it to be true, it disqualifies you as a rational person.
