How many holes does a straw have?

If a hole is defined as an absence of matter, the term can only be applied where we are certain that matter should be.

I submit that the straw is simply a continuous curved surface and that no matter ever existed or was intended to exist within the confines of the aforementioned continuous curved surface.

Therefore, there is no hole, there never was a hole.  A straw has no hole.

How many holes does a colander have then?

But you talk about "where matter should be" - and there shouldn't be matter where the holes are in the colander!

... Why has quarantine got me like so

Schoolboy error, PaddyP17.

There used to be matter there … and that has subsequently been removed in order to produce the colander.  Hence we have a hole (or several holes, in fact).

I'm surprised that you missed this point.  It's fairly obvious really … but I forgive you.  

Except a plastic colander, being moulded, never had matter there. 

From which we conclude that there are no holes in a plastic colander.

It's not difficult, is it?

Just clarifying colanders  can have holes and no holes.

Correct.  Entirely based on the method of manufacture.

The inner part of a chip pan would be another good example of the holeless basket.  Shopping trolley ... shark cage.  There must be others.

I have never read anything about holes on the internet that turned out to be nothing about holes...

Im still concentrating on the coriander, trying to see the holes, let alone count ‘em

No holes in a straw, it’s a hollow cylinder.

Then is a pipe the same?  How long does it have to be before you may consider it has two?

There will never be two. Just like Highlander, there can only be one. Even if you said “There’s a hole at each end”, it would be the two ends of the same hole. Assuming it is a hole, of course.

This is the basis for Schroedingers Colander. It like the cat one. You put a colander in a box, but until some opens the box to find out what it’s made of, you don’t know whether it has holes or not.

This is a magnificent concept, SomervilleAddick.  You may also have captured the thrill and excitement of receiving a colander for Christmas.

Imagine … you know that you're getting a colander (perhaps because of a careless remark by a loved one, or because you have been hinting for weeks), but you don't know whether it will be a man's metal colander (hence, complete with holes) or some pathetic, plastic wannabe colander (probably made in China) with … well … gaps and apertures, I suppose you would call them.

Are we talking leaves, seeds or powder?

Obviously a straw has no holes, it's a tube. A straw with a hole in it doesn't work.  A tube with holes in it is a flute or recorder.
