Picture of How to make a hexaflexagon
This is another magic pocket study tool I teach my students how to make. It is what is called a trihexaflexagon, which means basically a hexagon you can turn inside out to reveal a total of 3 complete faces (or sides of the paper). They put notes on these things and keep them in their pockets to make use of those odd bits of otherwise wasted time during the day (watching commercials during Channel One, waiting for the Pledge of Allegiance, after you finish your classwork...). Find enough odd bits of time, and you are done studying before you ever even get home! Now go have fun!

This is my second instructable. Clearly the first one wasn't exciting enough to win me a T-shirt... (-;

Step 1: Materials

For this project, you need a sheet of paper, a ruler, a protractor, scissors, and glue.

Hey, I've already confessed my compass crime.  But just in case you're holding it against me because you don't have a compass, you can make your own with a thumbtack, a strip of cardboard, and a pencil.  Maybe the subject of my next instructable, if I ever have time!

teachers like you are what makes school tolerable. things like this we're perfect wouldn't me when I was young cuz I was so energetic and could not sit still. I disrupted every single class I was in the teachers always said they loved me but they just couldn't stand to have me in their class cuz I would not sit still or shut up. the teachers I remember the most are ones that came up with projects like this for me because it kept me busy. keep up the good work your students will remember you.

Please answer to my question: How to glue this? (Step 7) "Glue the thing shut while folded horizontally." doesn't help. All triangles? I glued all triangles, but it doesn't work. (Or I really don't know how to "pull out from the center". I have a pink side and i pull out from the center and I have the same side!!! Please help me! ;( I'm very frustrated right now!! )
it means to fold it like this

a is the top of your paper and b is the bottom.
you fold from a to b to a and glue them together ( i hope that makes sense )
But, I can't really explain how to flip it... sorry :(
Check youtube. it might help

 This is the first comment I have made!

What you are using is a pair of compasses!  A compass will get you home but is not a lot of use for drawing circles - I should be a teacher.
 I know, but I was reading through the comments and couldn't resist saying something - the basic point about how clever the flexagon actually is was buried which just made it funny - I mean you no harm!

Oh for crying out loud.  Again with the compass?

I have confessed my crime.

Yes, you should be a teacher.  Because that's all there is to it - just knowing the difference between a compass and a protractor.

Why can't we just make a dot below the mid point of the 4 cm dots, instead of making those crosses?

 omg i just finished an exam today on symbiosis!
This is interesting, though I think probably more useful for elementary or high school study guides. I'm having a hard time seeing where I might use this for anything at the college level. Still, very cool flexagon!
be thankfull he put it on google

I love when people do that, except in real life, I'd have to say, She's a he.

I used to make hexa-hexa flexagons.  They had 6 separate faces,  numbered 1 through 6.  Normally all you get was faces 1 through 4 to show up in a row, but I figured out how to get them from 1 to 6 in order without having to go through any other faces.

I still have some of them tucked away in a drawer since I was a kid.  Don't know why i saved them, but I've had them for 40 years.

Too cool!

We used to make these in Elemmentary school about a billion years ago.  We actually got up to a duo-decka-Hexa-flexagon (20 sides if I remember corerectly) but alas I have forgotton how to fold them.  We used adding machine paper and no guideline  but they worked fine.

I have brought this up in conversations many many times but no one seemed to know what I was talking about.  :-(.

Thank you for posting this!

Because clearly I don't know the difference between a compass and a protractor. I should have called it a circle thingie.   I should be relieved of my duties.  (-; 
 why do you say protractor, but have a compass?
that is so hard !!!!!!
this is so cool! ima show it 2 all my friends. + i voted u
make a video
nerdnurture (author)  mikemmcmeans7 years ago
Video wasn't working on the gooseneck in my classroom. Sorry if the pictures don't suffice. My students are able to understand these instructions, so I don't really care to redo the whole process again just to make a video. Sorry. Someone else can do it if they really want to. (-;
