Air takes up space, has weight, and has pressure. These properties of air create forces that affect structures and can create natural phenomena that affect our way of life and have effects on our weather. The following experiment may give you some insight into the role air pressure plays on structures and the weather around us. Air pressure can be explained by Pascal’s law that says that the force of air acts the same in all directions. We don’t normally feel air pressure because the air pressure is evenly distributed all over and against our skin.
