I think a Martin Gardner article alerted me to the danger involved in these: he wrote about a guy whose tie got caught in one, and the guy ended up getting sucked into another dimension as he obsessively continued to flex it.

btw if anyone knows how to attach the ends without tape I'd love to know about it. I've made these for kids at bars but without a way of attaching the strip ends to each other, they're super-delicate.

I always just made an extra triangle to glue onto the first one. They're pretty robust that way.

It would be nice to have a pure origami solution, is all, so I'm not dependent on some sort of adhesive.
Maybe I can try a paper staple with two cuts or something.

Hee. Now I've read multiple articles about these, including reading (a reprint of) Martin Gardner's original 50s article when I was about 8. (In fact... *checks*... Yes, Wikipedia's section on tetraflexagons is still using two diagrams I created 12 years ago. That's pleasing.)

But that delightful pair of videos *still* had stuff I didn't know. Awesome!

I had a teen-aged period of being deeply interested in hexaflexagons (and their derivatives with far more layers) including making teeny ones (2 cm across) and enormous ones (2 meters across) out of various rolls of paper. It was back when adding machine tape was common in paper shops, which was useful for making normal-sized ones (and ones with lots of extra layers to them.)
