Can we settle this: how many holes does a straw have?
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?
If you are going topologically the answer is one, just like a donut.
Personally I like to think of a straw as a hollow cylinder of plastic, in which case the "hole" in the center is just space the cylinder doesn't occupy and not actually a hole, so zero.
