Here's George Hart's daughter Vi Hart making a Mexihexaflexagon, which is a kind of three-sided flat quesadilla: <a href="https://www.youtube.com/watch?v=GTwrVAbV56o" rel="nofollow">https://www.youtube.com/watch?v=GTwrVAbV56o</a><p>That family must have the best picnics!

Exercise to the reader: How do you slice the bagel so that you can spread cream cheese continuously along both sides. In other words, can you make a Möbious bagel?
My team at work thinks of every excuse possible to get bagels. Recently for a birthday, a work anniversary, and being restacked into new cubes. But this is the best possible excuse for bringing in bagels again on Monday.
Numberphile video on this topic, including 3d-printed examples of some higher-order slicings: <a href="https://www.youtube.com/watch?v=3_VydFQmtZ8" rel="nofollow">https://www.youtube.com/watch?v=3_VydFQmtZ8</a>
I wonder if it's possible to repeat the process in such a way that you make a chain. I'm trying to visualize how but I'm not certain whether it could only make more links all attached in the same place.
Just had a brief discussion at work about bagels that started with a complaint about how they're never sliced all the way through.<p>After a couple minutes of back and forth an epiphany was realized that if they were pre-cut all the way through they'd get jumbled up and then we'd spend way too much time rifling through halves to find a matching one.

Is it a sin to put pineapple on it?<p>Someone please ask Professor Shewchuk (UC Berkeley) and Professor Demaine (MIT) to look at this! Perfect geometric problem for both of them.
