A straw placed in a clear glass of water appears to break at the waters surface. Which explains this effect?
Refraction... The change in the density of the medium (from water to air) - causes the straw to appear to be bent.
Why does a straw appear broken as it sits in a glass of water?
Refraction bends the light, making the straw appear to be broken.
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?
Air pressure within the straw.
When we suck on a straw the liquid travels up. why?
Because of the suction the pressure in your mouth is lower than the atmospheric pressure on the surface of the liquid. This extra pressure pushes the liquid up the straw.
How does a straw work?
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.

Can you split a tree with straw during a hurricane?
No of course not. That is a myth that resulted from a rather result of tornado damage. A telephone pole was found split open with a straw inserted. However, it is more likely that the winds from the tornado split the pole and then the straw got stuck in the resulting gap afterwards. Lets not forget tornados can be as much as twice as strong as hurricanes, and far more dangerous.
How does air pressure help drinking through a straw?
when you drink through a straw you remove some of the air in the straw. Because there is less air pressure of the straw is reduced. But the atmospheric pressure on the surface of the liquid.

Air pressure within the straw.
How does straw function while drink?
When you 'suck' on a straw, you reduce the air pressure inside it. This means the air pressure on the surface of the liquid outside the straw is greater - so it pushes down, which forces liquid up the straw into your mouth.
Why are there air bubbles in liquid?
Air bubbles need a surface to cling to. Believe it or not, the surface of a plastic straw is not as smooth as you might think. You cannot see the roughness of the straw but it is enough for the bubbles to cling to and form there. The surface of a glass is usually smoother than a straw so bubbles have a harder time forming there. They just want to slide up the side of the glass to the top.

Why does when you cover up 1 end of a straw the water stays on the end?
surface tension?
How does drinking from a straw show fluids flow from areas of high pressure to areas of low pressure?
w,the pressure in the straw is reduced.but the atmospeheric pressure on the surface of the liquid stays the same.
When we suck on a straw the liquid travels up. why?
Because of the suction the pressure in your mouth is lower than the atmospheric pressure on the surface of the liquid. This extra pressure pushes the liquid up the straw.
