How Many Holes Does A Drinking Straw Have?

The video explores the question of how many holes a straw has, using mathematical and topological perspectives. It begins with common paradoxes and moves into a debate about the number of holes in a straw, considering various opinions. The video then delves into the definition of a hole, discussing whether it is a presence or absence. Using topology, it explains that a straw has one hole, similar to a circle or doughnut. The video concludes with a topological analysis, showing that a straw can be cut once without separating into two pieces, confirming it has a single hole.
