The speed at which liquid travels up a straw depends on factors such as the diameter of the straw, the viscosity of the liquid, and the force applied to push the liquid up. In general, liquids can travel up a straw at a rate of about 1-2 meters per second.
The liquid moves up the straw due to air pressure. When you suck on the straw, you create low pressure inside the straw. The higher air pressure outside the straw then pushes the liquid up to balance the pressure difference.
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.
When you suck on a straw, you create a partial vacuum in your mouth. This decrease in air pressure above the liquid in the straw allows atmospheric pressure to push the liquid up the straw and into your mouth.
As you create a partial vacuum in the top part of the straw, the weight of the entire atmosphere above the glass applies a pressure of 15 PSI on the liquid surface. This pressure pushes the liquid up the straw until the pressure in the straw returns to 15 PSI too. If you keep creating the partial vacuum the air pressure will push the liquid all the way to the top of the straw and out.
The last bit of liquid in a straw can be pulled up into your mouth through a combination of capillary action and your own sucking force generated by your mouth muscles. When you suck on the straw, you create a lower pressure inside it, which helps draw the liquid up and into your mouth.

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.

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
1) Air inside the straw moves 2)Pressure inside decreases 3)Pressure of the atmosphere is greater then the Pressure inside the straw=Liquid moves up the straw!!!
because when you suck up the liquid, it will just go right through the holes.
When you suck on a straw, you create a vacuum in your mouth, and the atmospheric pressure pushes the liquid up the straw and into your mouth. The difference in pressure between the area inside the straw and outside is what causes the liquid to move upwards.
When you suck on a drinking straw, you decrease the air pressure inside the straw. This creates a pressure difference between the inside and outside of the straw, causing the liquid to be pushed up into the straw and towards your mouth due to atmospheric pressure.
A McDonald's straw holds about 12528.1mm cubed liquid. I calculated the density and volume and came up with 12,528.1 milimeter cubed of liquid.
