Section 6.2 Orientable vs Non-orientable Surface
love this video. Many surfaces - like a piece of paper or a cylinder - have two sides, right? But not all do! Some only have one, like the mobius band. In this video we talk about orientiable vs non-orientable surfaces. This is mainly going to be relevant later because our theorems will apply only to orientable surfaces.
Learning Objectives:
Visually explain the difference between an orientable and nonorientable surface using normal vectors

Here are two more non-orientable surface to play around with: the
Klein bottle 1 and the
Real Projective Plane 2 . Cool, eh! (by the way, playing around with things like this becomes the subject called topology which is why my PhD is in and is awesome!)
