what about those bendy straws with the ridges in them. does a new hole start at every ridge?

1 hole, of course. Anybody that tries to make an argument for 2 holes is grasping at straws.

It depends upon whether you're describing just openings on the surface of the object, or the object holistically. In the first case, you can argue that it's two. In the latter, it's definitely only one.

I prefer the latter definition, because it takes into account the entire object, not just the observable surface.

If an open cylinder has one hole then how many holes does a cylinder with a closed end have?

There are no holes in a straw.

When looking at the definition of a "hole", we get this: "a hollow place in a solid body or surface.".
This means that we can have two ways of proving that straws don't have holes. First is that a straw is a tube, therefore a hole in it would mean that there's a hole in the tube itself, not on one of the ends.
Second, the way straws are made means that there can't be a hole since a straw isn't carved out of a solid piece of plastic, instead being molded into a tube.

So, a non-broken straw has 0 holes.

The hole is a lie.

-Does a straw have 1 hole or 2 holes ?
-Yes

But in all seriousness as the hole generally is on the same axis, it would be obvious it is considered 1 hole. Ås someone already mentioned a drilled hole in thick metal. Obviously its 1 hole for 1 screw or whatever. Id say even as a paradox or mind teaser its pretty bad at that

straw - 1 hole
straws - at least 2 holes, topic closed

if you consider the straw as a unique object governing the sub-properties we apply to it then it'd say 1 hole. it's just one cavity afterall. had it, say, plastic still remaining in the middle of it and acting as a sort of plug, then it'd be 2 cavity and thus 2 holes. but then i thought, what if we drill through it, perpendicularly through its body, piercing two times through it, and then melt the plastic around it, in the original hole, so that the body swaps 90° over ? if we cut the remaining parts past the new "hull" we'd have a small straw, with a single cavity, but two holes within a same layer of plastic. so i guess we should determine whether the straw is inititially constructed as a single body piece which then gets drilled in for a single cavity and a single hole, or if the same process as my example happened, say if we take a regular straw and melt each end to close it, we'd have to drill doing plastic to empty space to plastic again, making it 2 holes for 1 cavity, while going through a single piece would be all plastic until the cavity is done and thus a one single hole. maybe we should also consider the nature of what makes a hole, if it requires an "host body" from which to exist within, or if it can exist by itself, for example if an object is constructed in a such manner that it has always been hollow with a cavity running thorough its body (and maybe if such can be considered one). edit : i also think we can have 1 hole for 2 cavities if the origins of each cavitiy are significantly different. for example if you first put your fork halfway through a potato and then put a knife through the same potato from a different angle and reaching until the opening from the fork to make a single hole. but i wouldn't go as far as saying that then two cavities remains and not just one hole (and the question of the matter arround it might be adressed)

In a live quiz some months ago I put 2 as an answer thinking straws have two holes.
Unluckily my girlfriend who's way smarter and more acculturated than me told me they have one hole.
