I thought one of the more interesting flat earth arguments was that apparently a planes gyroscope doesn't have to be adjusted on trans atlantic flights. Turns out that's wrong and it is constantly self adjusting and that's one of the first things you learn in any piloting 101 book, which just goes to show you how deep this round earth conspiracy runs.

One thing I find more difficult to explain to round earthers is the faucault pendulum, maybe spoon has a theory how that's working and if it's another grand conspiracy or just some run of the mill pendulum elves.
