FLEXAGONS & OTHER COOL GEOMETRIC TOYS
In these hands-on tutorials, you’ll learn how to make a flexagon, a most fascinating geometric toy! It looks like an ordinary paper hexagon with a front and a back, but hidden inside is a third side (or face) that can be brought to the outside by flexing the paper.
Flexagons are folded paper polygons that have the neat feature of changing faces as they are flexed. There are many types of flexagons. The names of flexagons tell the type of polygon and the number of faces.
