So say you just moved from England to the US

and you've got your old school supplies from England

and it's your first day of school and you get to class

and find that your new American paper doesn't fit in your

So you cut off the extra and end up with all these strips of paper.

And to keep yourself amused during your math class

you can do with a strip of paper. You can fold it into shapes.

a nice symmetric sort of cycle to the flappy parts.

In fact, there's enough space here to keep wrapping the strip,

And you're like, "I don't know, hexagons aren't too exciting,

but I guess it has symmetry or something."

so the flappy parts are down and the unflappy parts are up.

That's symmetric, and it collapses down into these three triangles,

which collapse down into one triangle, and collapsible hexagons are,

you suppose, cool enough to at least amuse you a little bit during your class.

And then, since hexagons have six-way symmetry,

you decide to try this three-way fold the other way,

with flappy parts up, and are collapsing it down

when suddenly the inside of your hexagon decides to open right up.

you try doing it again. And again. And again. And again.

And you want to make one that's a little less messy,

so you try again with another strip and tape it nicely

that it would be cool to color the sides,

so you get out a highlighter and make one yellow.

Now you can flip from yellow side to white side.

Yellow side, white side, yellow side, white side

Hmm. White side? What? Where did the yellow side go?

So you go back, and this time you color the white side green,

and find that your paper has three sides.

And since it's shaped like a hexagon and you flex it

and flex rhymes with hex, hexaflexagon it is.

That night, you can't sleep because you keep thinking

And the next day, as soon as you get to your math class

You had made this sort of spirally folded paper

that folds into again, the shape of a piece of paper,

And use it like a strip of paper to make a hexaflexagon.

Which would totally work, but it feels sturdier

And you color the three sides and are like,

And you're sort of trying to pay attention to class.

And now it's orange, yellow, green. Orange, yellow, green.

Oh, there it is. Now it's back to orange, yellow, pink.

Yellow, pink, blue. Yellow, pink, blue. Yellow, pink, huh.

With the old flexagon, you could only flex it one way,

But now there's more flaps. So maybe you can fold it both ways.

And now, one way goes from orange to yellow,

but the other way goes from orange to...neon yellow.

to one of your new friends, Bryant Tuckerman.

You start with the original, simple, three-faced hexaflexagon,

And you're like, it's easy! Just start with a paper strip,

and you'll need nine of them, and you fold them around

into this cycle and make sure it's all symmetric.

The flat parts are diamonds, and if they're not,

And then you just tape the first triangle to the last

After all, it was invented only 10 years ago.

So he cuts out ten triangles instead of nine,
