Does a straw have one or two holes?

One elongated hole on the same general principle as a tunnel is a hole through a solid mass, usually rock.
The tunnel through rock is not an apt metaphor.
The rock started out as a solid mass with a volume that included the location of the (future) tunnel. The hole/tunnel was put into the rock, reducing the volume of rock.
By contrast, the straw's volume never changed. The straw was extruded around a tube-shaped space. The straw's tunnel was produced by inserting a separation between it and the surrounding space.
There is even Biblical evidence of this, so hear ye the word of the Lord.
6 And God said, Let there be a firmament in the midst of the space, and let it divide the space from the space.
7 And God made the firmament, and divided the space which were within the firmament from the space which were outside the firmament: and it was so.
8 And God called the firmament straw. And the evening and the morning were the second day. (Genesis 1:6-8)
Here endeth the lesson.
Thank you Jesus; thank you, Lord.
How to make a hole.
Take a pencil.
Lubricate it's surface with, let's say olive oil, extra virgin of course.
Wrap some plasticine around the pencil.
Withdraw the pencil and, hey presto, you have engineered a structure with a hollow centre, or in other words a long mini tunnel like single hole.
A straw has only one hole with two openings. Each opening can be any number of different lengths away from each other. it is the holes depth that makes it a straw, not the opening at the end of each hole. Remember if we look at any hole with only one opening it is simply no longer a straw. While not all holes simply with two openings is safe alterative to a designed straw.
A straw with a number of openings set outside the confinement set by order of hole is a flute. No matter how you thirst and no matter how many beverages may consumed within, the fluid will never play the tune set by your mind, and the minds thirst may not end.
I cannot tell you what you can only see. As you can not be shown what you can only hear. Is it the same hole used by the flute and straw? We only know it does not hold the same propose.
