This was oddly enough talked about almost exactly one year ago: http://news.ycombinator.com/item?id=982249

I should really have learned by now to hit searchyc before submitting.

If it is over a year old most likely there are a ton of people who haven't seen it, and those who have may not remember it completely.

Yeah, I totally agree... but it is also good to see previous comments as well. On my Hacker Newsletter I always post a couple items that are a year or more old and they always get a high click through.

And the only way I remember this was because I tried it back then. :)

Note that upon attempting to do this your wife will laugh at you during the several minutes it takes and then laugh more when you have to cut it to put it in the toaster to eat it. Oh and the bagels at the store were all pre-cut requiring extra work to find the bagels. Still worth it though :)

I’d totally use it at work for bagel friday, except for getting moved to a basement a full 3/8th mile away from the bagels…

Milton, is that you?

I found your stapler.

This is the single best reason to have a toaster oven.

I've heard that called the "Spanish waiter" trick and seen it done with full plates. It's cool.

one interesting thing is that this bisection of a toroid is eerily similar to leon chua's (http://en.wikipedia.org/wiki/Leon_Chua) model postulating the existence of the memristor. in it, capacitance, induction and resistance are at three cardinal directions around a toroid and he supposed that something must exist at the fourth.

And this isn't one of them!

Bagels tomorrow for breakfast.

And Cheerios in a couple of weeks!

Mobius strips? In my breakfast? It's more likely than you think!

Those aren't Möbuis strips.

They are twisted by a full rotation rather than a half. In other words, they have still two sides rather than just one side.
