If you’ve never heard of a hexaflexagon, prepare to have your mind blown.
This video is actually based on a true story. Arthur H. Stone really did invent the hexaflexagon after playing with the paper strips he’d cut off his extra-wide British paper, and he really did start a flexagon committee.
It’s also interesting to note that October 21st is Martin Gardner’s birthday, which is why every October, the recreational mathematics community celebrates his life and work. This year they’ll be having hexaflexagon parties.
