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.
Air pressure within the straw.
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.
The simple answer is that when you sip on a straw you draw air out of it. Since there cannot be a vacuum, the liquid comes up the straw to replace the air. But this is also happening: When you sip on a straw you cause a reduction in air pressure inside the straw. The air pressure on the liquid outside the straw is now greater than on the inside. Because nature doesn't like an imbalance, it gets pushed down into the glass and thus up the straw.
It is a more "rigid" material that allows for more vibrations and conducts more sound waves as a result.
I personally think you drink more when using a straw. I drink twice as much with a straw than tipping the cup.
No logic suggest that drinking through a straw will intoxicate you quicker. In fact, when drinking through a straw, we typically tend to take smaller sips of the liquid than we would if we just sipped it naturally.
They do not seem more rigid, they are more rigid! They both have cell walls. Many eubacteria, the bacteria you are most familiar with, have cell walls of peptidoglycan. Plants have cell walls made of interlocking cellulose.
The more humble homes were made of adobe, generally they were made of limestone though.
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 you avoid temporary and permanent teeth staining, eliminate wine-staches, and any lipstick and lipgloss stays on your mouth (not on the wine glass). And make sure if you use a straw for drinking wine, its a WineStraw!
more tenacious
You need to keep contorting it and moving it it will eventually become more hard to move, thus becoming more rigid. If you stop moving it it will become more like a liquid... just.. not seeping through your hands...
Just stab it with it. if it is not an extremely weak straw or an extremely firm apple, it should go into it. whether you'll be able to drink anything or not, I don't think so. I'd try it with an orange or other citrus fruit. would be easier to get juice out of :) EDIT: If you hold your thumb over one end of the straw, being careful to ensure a seal, when you push the straw against the apples skin, you will have formed a seal at both ends of the straw. As such the air in the straw is trapped. In order for the straw to deform (as it would tend to do by buckling, folding or bending when you try to force it into the apple) it must now compress the air in the straw rather than simply forcing it out of the open hole at the top. This is significantly more difficult, as the compressed air pushes back against the internal walls of the straw. This therefore means that a larger force would be required to compress the air and cause the straw to bend or buckle. In other words the straw is now stiffer / more rigid than it was. As more force can now be applied to the straw before it will deform, it is more likely to pierce the apple.
In a way... you are going to be sucking in air along with the liquid, which will cause stomach bloat and an accompanying feeling of fullness.
A clipboard is, nowadays, more likely to be made from a rigid plastic, rather than from plywood.
Actually, it's more common with root beer, but drinking ANY carbonated beverages is linked to non-ulcer related stomach pain. More so, it seems, when drinking them through a straw. The reason is that when you drink carbonated beverages without a straw a portion of the carbonation is eliminated, or neutralized, when it reacts to the saliva in your mouth. If you drink carbonated beverages through a straw, quickly, it fills your stomach with a lot of the gas caused when it reacts to the acid in your stomach, stretching the stomach lining and causing discomfort and pain. If you do drink carbonated beverages through a straw, drink them slowly and give your system time to adjust. You may find that your stomach is telling you to slow down, more often than you realize!
