Some Applications of Atmospheric pressure are listed below:
-Drinking straw: While drinking with a straw, one has to suck the straw. This causes the pressure inside the straw to decrease and the atmospheric pressure, which is greater will act on the surface of the water, which is present in the glass, leading to the sucking point (mouth).

-Vacuum cleaner: Vacuum cleaner applies the principal of the atmospheric pressure to remove dust particles. When We switch ON, The vacuum cleaner starts to suck the air along with dust. Increasing atmospheric pressure will push the dust particles inside the filter bag. 

-Rubber su-cker: When the rubber su-cker is put on a smooth or tiled surface, the air in the rubber su-cker is forced out. This is the reason causing the space between the surface and su-cker to have low pressure. The external atmospheric pressure which is higher, acts on the rubber su-cker, pressing it securely against the wall.
