Do Straws Have One Hole Or Two?

Here we go again... the internet is having another debate according to Delish. Do straws have one hole or two?

It is making me rethink too. Normally I'd say it would be two holes - one at the top and one at the bottom but argument for one hole makes sense too.

• one hole - "Just one. A hole needs two ends to be a hole..."
• two holes - "Two holes, one single column. Reasoning: If you're looking at the opening of a pipe, a very long pipe with the other end miles away, you are looking at a hole."

What do you think? One hole or two?
