How Many Holes Does A Drinking Straw Have?

The debate around how many holes a straw has, is one of fascinating debates to be a part of! There are those who say there are two holes while some feel there is only one whole. Some have gone so far as to claim that a straw has zero holes! By leveraging math and topology, this video explains why a straw is a cylinder with two circles at each end, but ultimately has only one hole as it can't be shrunk to a point.
