Lesson 3: Hexaflexagons

Hexaflexagon safety guide

Don't let a flexigatastrophe happen to you! Happy Hexaflexagon Month, in honor of Martin Gardner. Yes, we've been encouraging recreational use of hexaflexagons and even hexaflexagon parties to happen on Oct. 21, but be sure to flex responsibly.This is my third hexaflexagon video this month. The first two are also awesome.Hexaflexagons: http://youtu.be/VIVIegSt81k Hexaflexagons 2: http://youtu.be/paQ10POrZh8To learn more about flexagons, Martin Gardner, or hosting a hexaflexagon party, go here: http://www.puzzles.com/hexaflexagonI stole the "hexaflexadyslexia" joke from @matthetube: https://twitter.com/matthetube/status/255446894128529408I'm @vihartvihart. Happy Flexing! Created by Vi Hart.

• How do you make the hexaflexagon at ? She does it so fast.
• well acutally, from to maybe , she was at normal speed, shes just really good, you can see by the caption that says 1x speed. Most of the times she speeds it up, and in videos such as Dialogue for 2, she uses stop motion(:
• how do you make a hexaflexagon?
• Vi, I love the safety guide, but the danger of Hexaflexagons are inevitable. Squares and rectangles have always been and always will be, fourth dimensional time machines. Hexaflexagons are made from rectangular strips of paper, so I estimate using the same Haexaflexagon for a year will land you in the fifth dimension, in some unknown time period.
• Apart from making you confused, how can a hexaflexagon hurt you? Is this video meant to be a joke?
• Yes, it is meant to be satirical, which means sarcastic. In other words, yes, it is meant to be a joke.
• I can never figure out how you fold the Hexaflexagon, I've tried to make one with the insructions actually on the paper, but it never works out. Can somebody tell me how? Be specific, please, thanks :-]
• If you're having trouble, you may not be folding it correctly. I had that problem a couple times. It will be easiest to use someone else's instructions, just remember that you might not be folding it in the right spot or in the right direction.
Hope this helps.
• What does "chirality" mean at ?
• is this even a real warning cause all of this deems fake
