Above is an imagine of a two holed torus with an infinitely long pole through it.
On the left side we have the pole going through one hole and on the right we have the pole going through two holes.
Is it possible to deform the torus with the pole going through one hole so it becomes the torus with the pole going through both holes?
Details: The pole is rigid and cannot be moved. It is also impossible to slide the torus off the edge of it, it's infinitely long.
The torus is made of a Play-Doh like material. It can stretch but it cannot be ripped, you cannot stick two pieces of it together, you cannot pass it through itself and holes cannot be created or destroyed.
To show you what is allowed, here is an example of a donut (one holed torus) deforming into a coffee cup.
