because when you suck up the liquid, it will just go right through the holes.
When you try to drink through a straw in a sealed container, you create a vacuum within the container. The vacuum prevents the liquid from being able to flow through the straw because there is no air pressure to push it up. Essentially, the lack of air pressure inside the sealed container makes it impossible for the liquid to move up the straw.
When you create a vacuum in your mouth by sucking on the straw, you lower the air pressure in the straw. This pressure difference causes the liquid to rise up the straw and into your mouth, allowing you to sip the drink.
Sucking on a straw creates a lower air pressure inside the straw compared to the pressure of the liquid outside. This pressure difference causes the liquid to be pushed up the straw and into your mouth.
Liquid is held in a straw by a combination of cohesion, adhesion, and atmospheric pressure. Cohesion is the attraction between molecules of the liquid itself, while adhesion is the attraction between the liquid and the inner surface of the straw. The atmospheric pressure pushing down on the liquid also helps to keep it in the straw.
The control variable in this scenario would be a beaker with liquid in it that is not being blown into with a straw. This serves as a baseline for comparison to see the effect of blowing into the beaker with a straw on the liquid.
It would be more difficult to drink with a straw on the top of a mountain because of low atmospheric pressure. You would not have as much pressure to push the drink 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.
Suction.

Essentially, the lack of air pressure inside the sealed container makes it impossible for the liquid to move up the straw.
Sucking through a straw relies on atmospheric pressure to push the liquid up. In the airless environment of the moon, there is no atmospheric pressure to assist in the suction action, making it impossible to drink through a straw.
It is not recommended to drink liquid iron directly from a straw as it can be toxic in high doses. Iron supplements should be taken as directed by a healthcare professional to ensure safety and effectiveness.
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
You create a pressure difference in your mouth by lowering the air pressure inside when you inhale. This pressure difference causes the liquid to rise up the straw and into your mouth. The difference in pressure is what allows you to drink the liquid through the straw.
When you 'suck' on a straw, you reduce the air pressure inside it. This means the air pressure on the surface of the liquid outside the straw is greater - so it pushes down, which forces liquid up the straw into your mouth.
Yes, but it would have to be tilted, almost flat. You can only drink through it if your mouth is not more than 33 feet higher than the surface of the liquid that you're drinking through the straw.
because there is a gap throgh it therefore liquid can pass through it (:
That's because you suck in air instead. From an energy standpoint, energy gets wasted by the incoming air. But if the holes are rather small, and you suck strongly, you might still manage to suck in some liquid. Actually this is rather easy to explain, when you suck at a straw, you create a vacuum in your mouth. This makes the nearest molecules flow there. Like high and low pressure zones that create wind flows. But then with water via a straw. When there are holes in your straw, the first thing that is getting sucked in, is the air around you and the straw. Basically, you are wasting energy. The best thing to do is just get a new straw and enjoy your drink!
