Hi Wang Mei，

Cover the jar with the cardboard and turn the jar over. Next，take your hand off. Can you guess what happens? The cardboard holds the water in the jar! The air pressure pushing up on the cardboard is higher than that of the water pushing down from inside the jar. The higher air pressure outside the jar holds the cardboard in place.
