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?

Yeah, I think you can just make a half-twist instead of a full twist like the article does. Or any number of full turns + 1/2.

I should document this and make it my first HN post.

Don't you have a job?

This may have been the best comment I have read in days.

I'd rather just have a mimosa. :/

Leave it uncut. It already has a continuous surface.

But then you can't spread on the soft side.

Lazy answer: Cut it almost in half and leave it connected. Fold hinge around.

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.

Don't share it. Just wait until the next batch comes in and then cut a few like this while no one is watching.

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

Here's a short series on math-based Thanksgiving foods. https://www.youtube.com/watch?v=F5RyVWI4Onk&list=PLaNzoFtkQ7... It's hard to know where to stop recommending Vi Hart projects, I find them consistently cool and fascinating, so I'll just mention her blog http://vihart.com/ and Patreon https://www.patreon.com/vihart

Hexaflexagons are great and Vi Hart is great. Nice share.
