Ok, you know what a straw is and that you drink out of it (if you don't... look it up?), bet you never thought about how that worked ;D First off: No, you don't inhale the water up the straw and NO ITS NOT MAGIC. So knowing that... GUESS!! I bet you can't get it right  |

when you 'suck' on the straw it creates pressure, pulling the water up.

I'd say exactly right, but people just keep posting just o say that... and get their post count up... but whatever. It is how it works, but i think most people actually know that....

At least let some discussion! Most people haven't seen the thread. And its useless, as most of the people that can post in locked threads usually post anyway....

when you 'suck' on the straw it creates pressure, pulling the water up. GJ ;D but not exactly right, its a part of the answer. The Answer: When you put your lips on a straw you spread your mouth out (your jaw and cheeks) which makes the air inside your mouth have less air pressure than the air pressure outside. Since the air outside the water is greater than the pressure inside your mouth, it pushes the water up the straw. So... The greater air pressure on the outside of the water pushes the water up the straw into the lower air pressure in your mouth until the pressure on the outside and in your mouth are equal. |

What I know: When you sip from a straw, your bringing the Oxygen up, and sinice there's little space in there, not much Oxygen is there. So the power of your inhaling thru the straw, also brings the liquid along with the Oxygen up. Now let's look at the bottom of where your straw sipped. The liquid goes up, and the liquid around rushes in to take the space, and it happens continously, (sp. Shut up). You can adjust your inhaling to adjust how fast the liquid goes up.

Incredibly simple.
Firstly, air tries fill vacuums.
Secondly, when you breathe in, your diaphram lowers and this increase the volume of your chest cavity. This lowers air pressure
Thridly, the air tries to rush in to fill the cavity (thats how we breathe)
Lastly, since no air can come in (your mouth is wrapped around a straw for crying out loud) water comes in to fill the cavity instead.
See, simple and easy.
Oh, and you can never drink from a straw thats 1.5 (i think) metres tall (5 feet). This is because our lungs just dont hold enough room to suck that much air/liquid.
