How many holes does a straw have?

[Aroura]

So what you are saying is a donut has the same number of holes in it as say, a tortilla or a muffin, since a donut is fits the same criteria as a straw.

I don't know where you are getting your definition of hole, but:

hole
həʊl/
noun

1. 1.
   a hollow place in a solid body or surface.
   

By your definition though, only a depression is a hole, if it pokes all the way through, it is no longer a hole but simply part of the shape, I guess?  Actually wait, I can still travel along a hole in the ground, so even a depression isn't a hole.  So....holes don't exist?  Because I can always travel along the surface of every hole I can think of to reach any other point.

So black holes are really giant misnomers to you, I suppose.  If I poke through a piece of paper with a pencil it is also not a hole by your definition?  I have simply turned the paper into a new shape!

Well, if you really want to get that way, let's consider the fact that we're talking about a real physical straw, not a mathematical form.

In a real physical object, there are no surfaces all-- nothing but variations in the density of wave functions vibrating in a virtual space.

Answer's still zero, then, but for a different reason.

My kid actually gave me this answer. I found it clever coming from an 11 year old.

You still haven't explained how the answer is 0 if holes can exist at all, you just jumped right to the pedantic.  Either a straw has one hole, or there is no such thing as holes.  That doesn't make the answer 0.
