Can we settle this: how many holes does a straw have?

RealNooshie@lemmy.world to Ask Lemmy@lemmy.world – 237 points –

At work we somehow landed on the topic of how many holes a human has, which then evolved into a heated discussion on the classic question of how many holes does a straw have.

I think it's two, but some people are convinced that it's one, which I just don't understand. What are your thoughts?

In topology, yes. It must go through to count.

That's fascinating. So most of what I would call "holes" are what, in topographical terms, hollows? Depressions?

I don't even know if they have a name for that since it can simply be undone by stretching the object, which is allowed under topological rules.
