Can we settle this: how many holes does a straw have? - Lemmy.world

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?

How many holes does a rubber band have? A donut?

Topologically a rubber band, a donut, and a straw have the same number of holes. The hole at either end of the straw is just a continuation of the same one hole.

I disagree. A rubber band and a donut do not have an 'in' and 'out'.
Stick your finger through a donut, does it go in one side and out the other?
