Put this clip immediately after the flat Earth claim in your edit, then follow it with Bruh for a reaction beat before moving on to the next point in the discussion.
O tym dźwięku
This is a two-second Portuguese voice clip in which a speaker states, in plain words, that the Earth is curved. The delivery is calm and matter-of-fact, which makes the simple statement feel dryly funny when it lands after a wild flat Earth claim. It works as a short, confident correction rather than a heated argument.
