it is becuase when a glas rod charged by rubbing a cloth it aquires positive charge and when a plastic straw is charged by rubbing a cloth it aquires negative charge. Therefore a charged glass rod attracts a charged plastic rod.

∙ 14y agoThe charged rod attracts water because water is polar; the electrostatic charge pulls the opposite charge of the water molecule towards it. This happens regardless of the charge on the rod, because the water has both charges.
Carbon tetrachloride is nonpolar, however, and so there is nothing to be attracted to the rod.

∙ 11y agoBefore the plastic rod was charged it was neutral. When you rubbed the cloth on the plastic rod the negative charge from the cloth goes to the rod, making the rod negatively charged. The paper is neutral but because like charges repel, when the negative charges on the paper move away so the negative charge from the rod attracts with the positive charge from the paper making them stick.

Why is glass or chinaware packed with straw?
It's cheap, biodegradeable, and has the ability to be compressed and then return back to its original compression (unlike plastic air bags or popping plastic). It may also be used as a hydroscopic.
If you put a straw into a glass of water the straw looks to be bent although nothing has physically happened to the straw?
That is not strictly correct. The straw has undergone physical change: it is wet!
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.
Why does a straw bends when you put it in a glass of water?
The light gets refracted in water. Thus the shape of the straw seems to be bent.
How does water rise inside a straw?
The simple answer is that when you sip on a straw you draw air out of it. Since there cannot be a vacuum, the liquid comes up the straw to replace the air. But this is also happening: When you sip on a straw you cause a reduction in air pressure inside the straw. The air pressure on the liquid outside the straw is now greater than on the inside. Because nature doesn't like an imbalance, it gets pushed down into the glass and thus up the straw.
Do straw float in a glass of water?
Yes, plastic drinking straws will float in water.
Why a straw rubbed with a paper attracts another straw?
When straw is rubbed with paper it acquires charge due to friction. This straw when brought near uncharged straw induces opposite charge in the region of the uncharged straw nearer 2 the charged one. Then as the law is, unlike charges attract.
What principles is involved when you see a transparent object such as a clear plastic straw or a piece of glass in a clear liquid?

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 a straw fall out of a glass of coke?
What happens when you put a straw in a glass of Coke or any other carbonated beverate, is that bubbles of carbon dioxide form on the straw and cling to it, and since these are lighter than water, they tend to lift the straw up out of the Coke; when it is lifted high enough it will become unballanced and fall out of the glass.
Who invented the bendable straw?
Arthur A. Aykanian (b.1923), of Massachusetts, invented the first plastic bendable straw, the so-called "bendy straw." He had a patent on the first stay-bent plastic straw, as well. He was the inventor of the spoon straw, originally used for the 7-11 Slurpee.
What is a plastic straw?
It is a hollow tube made from plastic, used to sip drinks.
