Eric tries to do magic with a magic circle. Will he succeed in creating interlaced rings with only a strip of paper? It's not magic ... it's mathematical! The pedagogical side: This segment features the Möbius ribbon, a strip of paper with a half-turn and a single surface. We divide a band of Möbius into thirds. When you make two cuts along the strip, it magically turns into three interlaced rings that have no creases!
