Twist it.. Do bạn know exactly how to eat an oreo? well to do it, u unscrew it very fast, cos the kid who eats the middle of an oreo cookie saves the Sô cô la cookie outside for last.
Usually, twisting it works, but if there's resistance when bạn start twisting it, then bạn have to slide it, hoặc sometimes pull straight up (that last one hardly ever works, though).
