What Makes the Wind Blow explains the fundamental forces behind wind and air movement using real-world and laboratory demonstrations. The film shows that wind is caused by differences in air pressure, ...

Watch this fascinating demonstration of air pressure at work. Notice how the egg vibrates as the heated air escapes around it, and how it gets smoothly pushed into the bottle by atmospheric pressure.

But this science experiment help kids learn about the principle of pressure. Using a syringe and the mini-treat, young scientists will see the effects of air compression in a hilarious way.

For a 'street science ... streaming' pressure (ie the speed) goes down, the static 'sideways-pushing' pressure must increase to make up for it [2]. If you observe a stream of air suddenly speed ...

Before the age of science, it was clear ... the true nature and behavior of the air we breathe. 1618: Issac Beekman compares air to water, and the pressure water exerts at depth, and comes up ...

And you'll want to know which direction it's coming from. A barometer shows changes in air pressure. High pressure indicates good weather, low pressure indicates possible storms. By consulting ...

Air molecules colliding with a surface cause atmospheric pressure. Atmospheric pressure at sea level is about 101,000 Pa (101 kPa) but just 27,000 Pa (27 kPa) at the cruising altitude of a ...
