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.
If you put a straw into a glass of water the straw looks to be bent although nothing has physically happened to the straw?
When light travels from water to air, it changes speed and refracts, causing the appearance that the straw is bent. This phenomenon, known as refraction, is due to the change in speed of light as it moves from one medium to another.
What would happen if you put a straw in a cup of water?
The straw will displace the water, causing the water level inside the straw to rise slightly. When you suck on the straw, you create a vacuum inside it, pulling the water up into the straw and allowing you to drink it without tilting the cup.
What is difference between reflection and reflection?
the difference between reflection and reflection, is nothing. they basically mean the same thing unless you are thinking of it in other terms. Answer Do you mean reflection and refraction, if so then reflection is the immage you see reflected back at you when you look in a mirror. Refraction is when a light wave is bent. When you put a straw in a glass of water, you will notice that the part of the straw in the water is out of line with the part of the straw above the water.
Why does a straw hold water if you put your thumb over top of it?
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.
What is difraction?
when something looks bent when you put a straw in a cup of water and it looks bent that is difraction

How do you operate a water filter straw to purify water for drinking?
You can put the straw into the water and then suck, the water will come out filtered.
What happens to the level of water in the straw when you squeezed the bottle?
When you put a straw in a water bottle I think the straw stinks and then when you let go of breathing in the water bottle I think it increases and then after that I think when you boil water and then you put the straw in the bottle and put the boiling hot water in the bottle and then I think the straw is like cutting it thanks for reading this but I think it's the wrong answer sorry if it is

What would happen if you put a drinking straw into a half-filled cup of water?
The straw would displace the water in the cup, causing the water level inside the straw to rise above the water level in the cup due to atmospheric pressure. The water would remain at a stable height as long as the straw remains in the cup.
Why doesn't water in an eyedropper move?
vacuum is what holds the water in place. it`s the same thing as when you put a straw into a glass of water, hold your finger tight over the end of the straw and then lift the straw out of the water, holding the water inside the straw until you remove your finger from the end. in the case of the eye dropper, the water is forced out when the bulb is squeezed. vacuum is the force at work in both instances holding the water.

How do you make a homemade themometer?
That's easy...all you have to do is get dye(any color will do) water, clear straw(any other color will not work) and a glass jarwith a sealing lid . Then you combined the water and dye together put it in the glass jar, punch a hole through the lid(has to be big enough for the straw and small enough so that air can't seep out)Then you push the straw through the hole ( if there is some extra space in the lid after the straw is in the hole put tape around the seeping part). then block the top of the straw and tape it up the put the themometer in the sun
How can you put helium in a footballl?
