There are different ways of gluing solid tori along their boundaries, resulting in different manifolds (most common are S¹ × S² and S³). This video presents 2 ways to visualize S¹ × S² as the union of 2 solid toruses. One of them uses Heegaard splitting, which can be useful when studying 3-manifolds.
