Is there a “backyard” test to prove the earth isn’t a torus?

Question

I know the earth is a sphere, I’m definitely not debating that, but I also know there are various tests you can do on a relatively small scale to prove that the earth is not flat,. Are there similar tests that prove specifically that it is a sphere?

Answer 1

Yes. You can draw any circle on the surface of the Earth, then infinitely constrict that circle to a single point. This can’t be done on a torus.
