Answer 2

Answer:

Take a paper towel and shove it into the bottom of a glass. It should be packed in tight enough that it will remain in the bottom of the glass even when the glass is turned upside down. The air pressure in the glass pushes the water away, so that the water cannot go into the glass to get the paper towel wet.

Design an activity to show the effect of atmospheric pressure.
