How many holes?

If you cut the straw it becomes 2D.

Straw has one whole. :)

Not an argument

one hole and the hole is open on both sides. fuck you all

>what is euler characteristic

Wait people actually argue about this?

I have an 89 IQ and a straw has only one hole.

so this thread is just about arguing on the definition of a hole? lol?

>yfw you realize that the straw is homeomorphic to the sphere with 2 points punctured so it does indeed have 2 holes

So if you closed one side there would be one hole stillor half a hole? And then if you open a new hole in the end again its still one hole?
