w,the pressure in the straw is reduced.but the atmospeheric pressure on the surface of the liquid stays the same.
This is significant as the drink moves up the straw and into your mouth.
Sucking on the straw reduces the air pressure inside it. This allows 'natural' air pressure to push down on the liquid in the container, causing it to rise up the straw..
If you suck some air out of a straw, the remaining air in the straw will have to contract in volume in order to maintain the same pressure, which it will do because normal air pressure is still pressing on the liquid in which the straw is submerged. The contracting air will then draw up the liquid.
It is possible only if all the people in the world realize about the pollutions.
A bendy straw is a drinking straw with a corrugated, bendable section.
This is significant as the drink moves up the straw and into your mouth.
Because your sucking
Sucking on the straw reduces the air pressure inside it. This allows 'natural' air pressure to push down on the liquid in the container, causing it to rise up the straw..
when you drink through a straw you remove some of the air in the straw. Because there is less air pressure of the straw is reduced. But the atmospheric pressure on the surface of the liquid.
Basically, you reduce the pressure in the straw. The pressure inside the straw is less than the atmospheric pressure which presses down on the liquid outside.
"Muscular action reduces air pressure in the mouth, whereupon atmospheric pressure forces the drink up the straw." ~ Wikipedia
Drinking from a straw is the same as an egg going into a glass bottle, because air pressure in both cases is used to move something. In the straw, you reduce the air pressure in the straw, so the air pressure around the drink pushes it up into the straw and into your mouth. In the egg, you reduce the air pressure in the bottle, and air pressure around the egg pushes it down into the bottle.
It is simply creating a low pressure
when you drink through a straw you remove some of the air in the straw. because there is less air the pressure of the straw is reduced. but the atmospheric pressure on the surface of the liquid remains the same. henceforth how it helps you drink
As you suck on the straw air is removed from the inside of the straw and the air pressure within the straw is reduced. Once the straw's air pressure is reduced past atmospheric pressure of about 760 mmHg, the Patm forces the drink up the straw and into the sucker's mouth. Gases move from high to low pressure areas until equilibrium is reached.
It is all to do with air pressure. We lower the air pressure inside the straw by sucking the air out of it, atmospheric pressure which is pushing down on the surface of the drink literally forces it up the straw into our mouth.
The drinking straw as we know it today was invented in 1888 by Marvin Stone.
