Book #169

Flexagon 1

Today's structure is a simple flexagon. Flexagons allow a number of faces to be revealed, depending on how they are folded and unfolded. There are many ways to make a flexagon if you search online; but, if you investigate flexagons too much, it becomes a very elaborate mathematical challenge to make more complicated flexagons with more faces and using different shapes (be careful)!

There are some good books about flexagons like The Magic of Flexagons if you want to really get into it.
