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.

An curved arrow pointing right. Astronaut Jack Fischer demonstrates what happens when you blow bubbles into a water bottle in zero-gravity. You can follow him on Twitter here. Produced by Jasper ...

You will probably get even wetter using this technique. As you pump, you can see air bubbling into the bottle. When the pressure is too great for the cork to contain, the cork is pushed out.

When the pressure drops in the cabin of the plane, what air is in a container ... If you have a bottle with a straw, you can open the lid as your plane climbs high into the sky.

The bottle is a closed system, and the only way to increase its pressure is to squeeze it into a smaller shape, or else add ...

and ducting into the engine, the air has heated to roughly 0 degrees. This still is very dense air, which is why the engine responds with such a huge power increase. As the pressure in the bottle ...

The air pressure increases ... Think of a bicycle tyre. Pressure increases when particles move faster. To do that you can either add more particles into the same container, reduced the volume ...
