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?
One. Imagine a cube of steel. Now you take a drill and you drill an hole into this cube. Now you saw around that hole so it has a wall thickness of 1mm. Now you have a straw made out of steel and you’ve drilled only one hole.
