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.
What else can I help you with?
How does the last amount of liquid in a straw get into your mouth when the cup is empty and there is no more surface liquid for atmospheric pressure to work on forcing the liquid up the straw?
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.
When you drink a soft drink with the help of a straw what forces the liquid 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.
How does the length of a straw affect how high or low the note is?
longer straw, lower noteshorter straw, higher note
Why does a straw bends when you put it in a glass of water?
When you put a straw in a glass of water, the air pressure inside the straw is lower than the atmospheric pressure outside the straw. This pressure difference causes the water to push into the straw, creating a buoyant force that bends the straw.
Why does a straw bend when it meets water?
When a straw meets water, the water molecules are attracted to the straw due to the force of surface tension. This attraction pulls the water up the sides of the straw, causing it to bend as it follows the shape of the straw.
How do straw rockets work?
Straw rockets work by blowing air through a straw, which propels the rocket forward. The force of the air moving through the straw creates thrust, pushing the rocket in the opposite direction. The fins on the rocket help stabilize its flight path.
Can you drink out of a straw after you have dental work done?
Not if the dental work is wisdom teeth removal. Sucking on a straw will cause the stitches to come out and the incisions to start bleeding again.
How do you make a straw that won't work?
Sabotaging a StrawPutting one or more pinholes in the straw, above the level of the liquid, will allow air to enter the straw at the top, and the liquid will not rise in the straw. To use this "sabotaged straw", merely switch ends (flip it over) so that the pinholes go under the liquid.

Why will a straw not work on moon?
When you suck on a straw you generate low pressure, so that means the pressure outside the straw, by contrast is higher and so matter gets sucked into the straw. On the moon there is no atmosphere and so the pressure is zero. No matter how hard you try you cannot create a pressure of less than zero inside the straw and so no suction can occur.
