He is afraid that he will get wet.
He concludes that air is stronger than he thought.
□Put a piece of cardboard over the jar.
□The jar of water is upside down，but the water stays in the jar. This is because air pressure pushes the cardboard onto the jar.
□Fill the glass jar with water.
□Turn the glass jar over quickly. Hold your hand on the cardboard for a few seconds.
□Remove your hand from underneath the jar. What happens
□There is more air outside the jar than inside，so there is more air pressure outside than inside.
