Air is always around us. Even though we can't see or feel air, we know that it is there. We can observe its effects in the forces of air pressure and wind.
Did you know that air pushes on us? Air pressure is the weight of the air pushing down on us and on everything else around us. Air pushes on you with a force of about 14.7 pounds per square inch. That's like a bowling ball on every square inch of your body! Why don't we feel it? Because we're used to it. It's constant. We've felt it every minute of every day since we were born.
