44. World Checker [c.1922-1991]
After much observation, it is clear that Muggles must use the World Checker to do precisely that — check on the world. From scholar’s houses to schoolrooms, one can observe Muggles far and wide walking up to the World Checker, spinning it for a bit, and pinpointing certain countries. Curiously, the most commonly checked area of this object is the North Pole.
