the air in the liquid is blocked off by your mouth when its on the straw so when u sip the flow of air and carbons bring the liquid thorugh the straw
through capillary action http://www.answers.com/topic/capillary-action-1
The power of suction. If you suck through a straw, the air within as nowhere to go as does the water inside it other than your mouth. Straws allow you to suck in any liquid you stick them into. That is, as long as the straw does not have a hole in it.
because the light from the straw is refracted when it travels from water to air. see Snell's Law.
I'm only twelve in sixth grade believe it has something to do with reflecting and bouncing off of certain thing's. Sorry I don't have any more info.
If a person looks at a straight object, such as a pencil or straw, which is placed at a slant, partially in the water, the object appears to bend at the water's surface. This is due to the bending of light rays as they move from the water to the air. Once the rays reach the eye, the eye traces them back as straight lines (lines of sight). The lines of sight (shown as dashed lines) intersect at a higher position than where the actual rays originated. This causes the pencil to appear higher and the water to appear shallower than it really is. The depth that the water appears to be when viewed from above is known as the apparent depth.
I believe that it's because the alcohol has a lower evaperating temp. and lowers the temperature of the condesation of water on the straw.
No
Water is a fluid and bend but not to move its molecule is changed.
Refraction bends the light, making the straw appear to be broken.
This is due to the principle of refraction. Refraction occurs at the boundary of the two media air and water. When a light ray hits this boundary at an angle, it changes direction and seems to bend. So. the straw appear bent when we look at it through the water glass because light is being bent as it passes through the different media of air, water, and the glass.
No. The only effect would be that a pencil, a ruler, or a soda straw dipped into the water would appear to bend toward you under the water, rather than away from you as it does now.
refraction of light
Refraction of light
refraction (beams on light bend in the water)
Because the water particles will bend the light. I think :)
The fingers appear to bend sharply at the surface of the water.
Refraction... The change in the density of the medium (from water to air) - causes the straw to appear to be bent.

A straw looks "bent" when it's in water because water causes light to "change course" when it moves from air into the water. The light will again be caused to change course when it leaves the water to go back into air. This is called refraction. Refraction is a fundamental property exhibited by a wave that changes mediums through which it is traveling.Or, making it simple..A straw seems bent because water is denser than air, so when it changes from air to water is applied it seems bent.
bye straws that are already bent
