The video shows a person cutting a bagel in half with a knife. The bagel is yellow with black poppy seeds on top. The person is holding the bagel with one hand and cutting it with the other. The knife is silver and has a black handle. The background is a red table. There is text on the screen that reads "and it has a left and a right. So, it divides into two halves. But if we cut it along a Mobius strip, it's not going to be quite the same."
