Importance of atmospheric air pressure- Science Mug experiment

 The atmospheric air pressure is extremely beneficial for us, for its absence would have made it impossible for us to drink anything through the straw.

So lets start the experiment

Take some water or any other drink of your choice in a glass tumbler. Put two straws into it. Now hold one of the free upper ends of the straw by your mouth and suck in air from it. This suction will mean that you are drawing out part of the air held inside the straw.



The air outside the straw starts asserting the moment part of the air from inside the straw reaches your mouth. It starts putting pressure on the drink to fill in the vacuum created by the air sucked in by you from inside the straw pipe. This process of sucking in the air and filling in the vacuum thus created by the drink continues till the drink remains in the tumbler.

The second straw lying in the tumbler remains unfilled by the drink as the conditions of varying air pressure do not apply on it.
