Air Pressure

Air pressure is the weight of air. Air is a gas and takes up space and has mass. Explore the effects of these facts and see applications of air pressure. Boyles law is explained as well as the reason why a suction cup works

The explanation on how planes work is WRONG, planes can also fly upside down. Unfortunatly it is not simple to explain how planes fly, you need vortices and vector calculus :)

[atemme]

The explanation is CORRECT. Do you dispute the Bernoulli effect? It is just not a comprehensive explanation of every detail of what makes a plane fly nor was that the intention of the video.

When blowing a balloon up by mouth could the condensation from the lungs give a false reading of the mass of the air?

Nice clip was fun. Since I started flying I have become completely fascinated by air. I wish to build an aircraft and I will be experimenting with drag and airfoils in water.

[atemme]

This experiment was to simply prove that air has mass. I did not intend to show an absolute value of mass. It would vary based on the mix of gases one happens to capture.

Correct, the vacuum pump removes air from the chamber. Crack the glass and it'll implode upon itself all caused by the surrounding air pressure.

wow this isn't anything like bill nye at all!

[atemme]

Thank you for the incredibly sarcastic compliment!

[Tfkeerful]

air pressure is surly cool !!

[wannaplayscoot]

Nicely done.

@MapleOryDude the water vapour inside the can gets cooled back in to water wich takes up less space as he says, and the pressure inside the can becomes lower than the pressure outside it

Ummm, you should mention that you're measuring "the same stuff" as the air around the balloon; obviously if you used helium to fill the balloon, the balloon would weigh less after inflation! Keep making videos; kids relate much better to demonstrations than textbooks!

Thank you , I used some of this for my class , thank you again.

OLD fashion outo tune

4:05- 4:30 i don't get it

[MapleOryDude]

thanks you man, i am suppose to know this at what grade?

[supressorgrid]

@atemme Does this mean that if you hit a democrat on the head his noggin could implode?

[FakemeraldLove]

Thanks alot! Nice explantation :)
