Yes, straw is a cylinder-shaped object with a hollow center.
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.

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.
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.
The pressure in the straw goes to negative.[We cannot have a negative pressure - this grammar form is known as an oxymoron.]A2. The pressure in the straw is reduced, and thus the liquid is able to be drawn higher in the straw.

A hollow cylinder.
If available, a small, glass graduated cylinder would be best. Next best would be a test tube or any clear or semi-transparent cylinder/ small plastic recycled container/bottle. If an eyedropper is not available, recycle a milkshake straw to move/transfer small quantities of a liquid. Place the bottom end of the straw in the liquid almost to the bottom. Then hold your thumb tightly to the top end of the straw and lift out of the liquid. When you remove your thumb the contents will spill out of the bottom of the straw.
Not quite. While they are similar shapes, a cylinder is usually solid (like a peg or a tin can, before it is opened) while a tube is hollow (like a pipe or a straw).
A standard drinking straw is a cylinder. The formula for calculating the volume of a cylinder is: Pi x r2 x length. So, a drinking straw that is 9.5 inches long with a diameter of .25 inches (1/4 inch) has a volume calculated like this:Pi (3.1416) x radius squared (.1252 = 0.015625) x length (9.5) = 0.46633125 cubic inches

If you allow the drop to roll or travel down a small cylinder or rod like a straw, a spoonhandle. glass rod, etc.
The paper left on a straw is typically referred to as a straw wrapper or straw sleeve. It is used to keep the straw clean and hygienic before use.

A Straw Poll
Depends on the straw...
No, not a drinking straw. As for straw as in grass, I guess someone could eat that.
