Yes, in the video I'm talking about [this video] he says that a bootle has an edge (~3'40). A sphere does not have an "inner surface", it has just one surface. So does a potato. If you go from sphere to potato to bowl, when does an edge appear and does it have to appear, is my question.
Video claims a bottle has an edge, prompting a topology question
