Mysteries Of Flexagation

In this, her latest video, fast-thinking, faster-talking maths wizard Vi Hart presents us with the typologically fascinating hexaflexagon. First discovered in the 1930s by a day-dreaming student named Arthur H. Stone, "flexagons" have attracted the curiosity of great scientists for decades, including Stone's friend and colleague Richard Feynman. Here, the ever-capable Hart introduces the folding, pinching, rotating, multifaceted geometric oddity with her signature brand of rapid-fire wit and exposition. She even shows you how to make your own.
