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.

When you drink a soft drink with the help of a straw what forces the liquid up the straw?

When you suck on a straw, you decrease the air pressure inside the straw, creating a partial vacuum. The higher air pressure on the surface of the liquid outside the straw then pushes the liquid up the straw and into your mouth.

Why dosent air pressure crush an empty soft drink can as you drive down a mountain?

The empty soft drink can has a higher pressure inside compared to the lower pressure at higher altitudes. The pressure difference between the inside and outside of the can prevents it from collapsing.


How do straws work?

Drinking liquid through a straw uses the invisible pressure of the atmosphere to move a column of liquid. The air all around us is under pressure, from the rest of the atmosphere above it pushing down. (This is about 15 pounds per square inch at sea level.) You are reducing the pressure at the top of the straw*. The air pushing down on the surface of the liquid will force the liquid up the straw. So you are technically not "pulling" the liquid, it is being "pushed" by the air.*When you suck on a straw, the diaphragm under your lungs drops down, reducing the pressure in your lungs. This reduces the pressure in your mouth and likewise at the top of the straw.Air Pressure ExperimentYou can show that the air has pressure by inhaling at the top of an empty plastic bottle (a two-liter soft drink bottle is perfect for this). The sides of the bottle will cave in as you remove air from the bottle.(see related question)

What is the difference between a milkshake straw and a soft drink straw?

Milkshake straws are larger in diameter than soft drink straws. Since milkshakes are thick, they are very hard to drink with a small straw, thus the increased diameter of the straw makes it easier to drink.

Why straw are used to drink soft drink?

Straws are used to drink soft drinks primarily for convenience, allowing people to sip beverages without needing to tilt the cup or can. They can enhance the drinking experience by keeping the drink's carbonation intact longer and minimizing contact with teeth, which can help reduce sugar exposure. Additionally, straws can be more hygienic in certain situations, such as when sharing drinks or in public settings.
