Luckily we have a field of mathematics to solve problems like this. "Topology... is concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself" (Wikipedia).

From my (admittedly basic) understanding, a straw is topologically identical to a donut (torus), which has only 1 hole.
