Last week I posted a new flexagon/fidget toy I invented after Paula Beardell Kreig inspired me to play with little squares of paper. I came up with a second design, which is the subject of this week’s post.
I am more comfortable with calling this one a flexagon as it rotates in a consistent and predictable pattern. You begin its construction the same way as the one I showed last week. When you have assembled your line of triangles (but haven’t glued them in a circle), the process changes.
Orient your strip of triangles so that the smooth edge is on the right and the triangles are on the left. Fold the upper end of the strip behind so that you have one full triangle on the left and the rest of the strip sticking out to the right.
Fold the right hand end back and down. The pointy finger in the image below indicates the fold line. You should have a square shape with a bit projecting from the bottom right edge.
Fold the projecting bit behind the bottom tip of the square shape.
Fold the last projecting bit up and behind the square.
Take the point on the left (indicated by the pointy finger), move it behind the other layers, and glue in place. You need to glue the same area as you did when gluing all the other triangles together. (The orange patch indicates the gluing area.)
By marking the upper right corner of the flexagon with a paper clip and a scrap of paper I was able to count the number of moves before the flexagon returns to its original position.
The square opens along the centre vertical line. Fold the sides of the square back. (This may be tricky the first few times as the paper gets used to flexing along certain folds.)
You should get a diagonal squashed hexagon. Open this along the horizontal line.
You have returned to a square shape, but it obviously isn’t the first square as the paper clip is just peeking out in the middle of the bottom right section. Open the square along the vertical line again.
You are back at the squashed hexagon and the paper clip is on top on the lower left.
I will need to decorate the flexagon to make it clear which parts of which surfaces appear on each rotation!
