The description of microtubules is hollow rods or hollow cylindrical structures. They mainly help to shape and support the cell.
The Guiro is made from a hollow gourd.
A musical percussion instrument (drum); usually consists of a hollow cylinder with a membrane stretched across each end.
There isn't an answer to this question. Perhaps it needs to be re-phrased.
Hollow tubes are cylindrical structures that have empty spaces or cavities inside them. They are commonly used in various applications, such as piping, structural support, and biological systems. Examples include straws, blood vessels, and plumbing pipes.
If allowed to thoroughly dry out, the pulp in the gourd evaporates, leaving only the hard, dried seeds inside. When shaken, such a gourd rattles - the basis of the percussion instrument called the "maraca".
A cup is usually a roughly cylindrical hollow container. The circumference of a cup would be the length of a piece of string wrapped around the cylinder.

The first "real" percussion instrument would be a drums as this is easy to do, extending a pig skin onto a hollow cylinder. So first percussion: Stones First "real" percussion: Drums
The magnetic field outside a hollow cylindrical wire with current flowing is similar to that of a straight conductor, following the right-hand grip rule. The field lines will be circular loops around the wire, with the magnitude decreasing as you move away from the wire according to the inverse square law.
A tube is a hollow, usually cylindrical body of metal, glass, rubber, or other material, used especially for conveying or containing liquids or gases.
