Highly doubted it, calculated it, proved it, still don’t believe it! How can a mere 6m increase in circumference cause a 1m increase in height all around the earth? (Earth’s radius 6400000 does become 6400001 when you add 6.28 to the circumference)
-
Because when you think about it 1m is an absolutely insignificant distance compared to the radius of the earth

Yep. And exactly the same maths works for the Earth, the moon and a beachball.

So now I'm gonna go look for the basketball I know is in our messy garage somewhere to test this, albeit with a lot of hand-waving.

Hah nice try! The Earth is flat so you won't be able to

Too bad the earth isn’t a perfect sphere :(

Doesn't need to be. If you take any shape* and trace out a line that's always a distance d away from it, the difference in perimeters will always be πd. ( *exception: if original shape bends back on itself with concave radius of curvature < d, then new perim < orig perim + πd )

Does one use a natural fiber or synthetic string? Doesn’t the string get wet and stretch in the Pacific? How do you account for the Himalayas? Spool must be kinda big, right? How many people to lift the string?
