Air Has Mass
Place an empty balloon on a scale and weigh it. Take thissame ballon and inflate it. Weigh it again. What do you see?.A really clear way to show this is to make a balance with astick or coat-hanger suspended by a string in the middle.Tie an empty balloon on each side to prove they weigh thesame. Inflate one balloon and rehang it. That side of the
Air Takes Up Space
Take an empty ziploc bag, open it and pull it through the air like aparachute. Now close it, seal it and try to squish the bag. There’snothing in the bag, right? Wrong. The ziploc bag is full of air.
You can also prove this by blowing up a balloon. The balloonexpands because you are putting something into the balloon; air.This air takes up space, so the more air you put into the balloon,the more space it takes up. When you use a pump to blow up afootball, you don’t put nothing into it, you put air into it - this airtakes up space which is why the football expands.

balance will be heavier. If air had no mass, there would’vebeen no change.
Air is really quite heavy. It is just that it has always beenthere for you and me so we do not notice. Asking a human ifair is heavy is like asking a fish if water is heavy.
Every square inch of surface on the earth has about 15pounds of air sitting on it. (Air is piled about 100 miles highon each square inch.) Just for fun, calculate the number ofsquare inches on the top of your head and multiply it by 15.Wow... you are holding all that up!?!? Try it Yourself:
Balancing Act | Feel the Force
Air Exerts Pressure
Take a metre stick and lay it on a table. Unfold a full page of anewspaper and lay it flat over the metre stick. Push down onthe other end of the metre stick. What happens? Why can’tyou lift a super-light piece of paper? Air exerts pressure (inall directions).
The air above the paper pushes down on it (pressure). Thispressure is what makes the paper lay flat on the table - it’sbeing pushed down. Even though they’re too tiny to see, allthe molecules of air in the atmosphere above your headweigh something. And the combined weight of thesemolecules causes a pressure pressing down on your body of10,000 kg per square metre (10,000 kg = 22,000 lbs). Thismeans that the mass of the air above the 0.1 square metrecross section of your body is 1,000 kg, or a tonne.
If you tried to lift a small car, you’d definitely notice it, so whydon’t we notice that there’s a tonne of air pressing down onus? Well, the air exerts this force in all directions, so aswell as pushing down on us, it also pushes up and balancesout the force on our bodies so that we don’t collapse.
