How does air stay in a football?

When a soccer ball air valve is closed, the hole is perpendicular to the passageway, which doesn’t allow air to enter or exit the ball. Whatever air is in the ball will stay inside. When the valve is open, the hole runs in the same direction as the passageway. This allows you to inflate the ball with air.
