One straw because there is a gap between the middle of the two straws which lets in a lot of air allowing you to drink less
You get more water in 1 straw then you get out of 2 straw because when you have 2 straws you just get more air then water.
The liquid inside the straw vibrates as it gets sucked up, creating a slurping noise. The air inside the straw also vibrates as it is pushed out when blowing into the straw, producing a whistling sound.
When a thumb is placed over the hole in the top of the straw, it seals the entry way for air. When the straw is pulled out of the water, it is to be noted that a drop or two of water falls out of the bottom but no more falls. This is because when the water droplets fall, this creates more space in the air pocket in the top part of the straw. WIth more space the pressure decrease in the air pocket. In addition, gravity is working on the water inside the straw, but these two forces do not outweigh the force of atmospheric pressure outside, as a result, the water stays within the staw.
When a straw is rubbed with a sheet of paper, friction causes electrons to transfer between the two materials. The straw becomes negatively charged as it gains electrons, while the paper becomes positively charged as it loses electrons. This can result in the two objects attracting or repelling each other.
When a student uses a straw to blow a stream of air between two papers, the difference in air pressure causes the papers to move apart. This is due to the Bernoulli principle, which states that as the speed of a fluid (in this case, air) increases, its pressure decreases. The faster-moving air between the papers creates lower pressure, leading to the papers separating.
Wait for 1 hour befor eating or drinking, advisable to wait at least 24 hrs before smoking
Wouldn't it be the same? Coz you can only fit so much water in your mouth at one time? I'm no Scientist tho!! xx :)
Yes, just about all one-cup coffee makers are faster than the typical 10-cup brewers. They heat the water up much faster. For an even faster cup of coffee, consider the Keurig machines that will have you drinking a hot cup of coffee in under two minutes.
The original drinking straws were hollow grass stems made of... straw. On this date in 1888, marvin-stone-1, who was already manufacturing paper cigarette holders, patented a new process for making drinking straws. He wound strips of paraffin-coatedpaper around a pencil and glued them together. Within two years, production of the straws had surpassed that of the cigarette holders. The manufacturing was done by hand until 1906, when Stone's company created a machine to do the job.

A straw has one continuous hole that runs from one end to the other. This single hole allows liquid to flow through it. Although it may seem like there are two openings, they are connected by the same tunnel, making it one hole.
Two bodies are you but both joined in one the stiller you are the faster you run?Buddy, your an Hourglass.:D

It is recommended that you refrain from using a straw for at least ten days to two weeks following extractions. The reason is that anything that can cause suction pressure in the mouth can cause the blood clot in the socket to be lost prematurely. This can lead to a very painful condition known as a dry socket.
It's a matter of air pressure that acts on the water. When the straw is uncovered, there are two forces acting on the water inside. There is gravity, pulling the water down, and air pressure. The pressure is about the same on both ends of the straw, but on the top of the straw, the pressure pushes the water downward, and on the bottom of the straw, the pressure pushes upward. Both of the pressures are the same, so the net force is just the force of gravity pulling the water down and out of the straw. When you cover the top of the straw, you block the air from pushing down on the water. In this case, the only forces on the water are the air pressure pushing up, and gravity pulling down. However, the air pressure is a greater force than gravity, and keeps the water in the straw despite gravity's pull.
well i think two can? but none have a drinking problem or anything.....
no
