How many holes does a straw have?
okay. Straw exists in three dimensions. Um, so top a. Logically. It has one hole. It's technologically I equivalent to a doughnut, which has one hole. But you could say that it's a two dimensional object because the plastic is so thin, in which it's a two dimensional objects wrapped around itself in existing in two dimensions. And then it's technologically equivalent to a sphere with two holes. But yeah.
