Final answer:

Air pressure counteracts gravity, keeping the water in the cup when turned upside down.


Explanation:

Pressure plays a crucial role in keeping the card and water in the cup when turned upside down. When the card is held over the cup, the pressure of the air above the water creates a force that acts against the force of gravity, preventing the water from falling out. This is due to the concept of air pressure exerting force equally in all directions.
