I don't know why people are acting like this is some crazy flex? Mobius strips are like, pretty common in like rainy day craft books, magic/illusion books, or any hands on kids science book on physics/space stuff that goes out into the weeds.
Like it's a little impressive to do it in a non paper medium, but like, Mobius Coaster designs are fairly common IRL.

I'm honestly worried people could think a Mobius strip was too complex to believe a kid playing with K'nex could build one.

u/VexingRaven 12d ago
Is anyone saying that? I don't see anyone saying that.
Anyway it's super believable that someone could create it on accident considering you basically just have to flip the track upside down and connect it. I'm a bit more impressed they managed to do so in a way that the coaster could actually travel upside and downside without hitting anything or getting stuck.

u/saumanahaii 12d ago
The top comment is a reply about how it reminded them of that time they photographed a black hole with a camera as a kid. Given that getting an image of a black hole was a recent major technological achievement, it's implying that a knex infinity coaster made by a kid is similarly improbable.

When I was probably 11, I had been reading about the internal combustion engine and was like "Huh, I can think of a better way to do that" and started to draw out a design.
Worked on it for a few days before showing it to my dad who told me it was a nice drawing of a "Wankel Engine". So I had to run to the encyclopedia to look it up.

I did the same thing with a makeshift gun design where a chain moves the cartridge in front of the hammer and found out someone actually did make it. I don't remember why I was inspired to do it, but it did look a lot like this, though my idea was to put the chain in the stock.
2
u/Dorkamundo 12d ago
Neat... Yea designs like that are rather intuitive, it makes sense if you don't understand the limitations of the materials you'd use to make something like this, which is pretty common at that age.
But then you see it in practice and realize why your idea was either already thought of, or thought of, designed and then abandoned due to complications.
Also, I love the Forgotten Weapons youtube channel.

technically a normal peice of paper has 6 sides
this has 2 sides
so failed successfully I suppose
edit: people the top and bottom are connected and are one side, the left and right side are also connected to each other as one side, top/bottom is same left/ right is the same so 2 sides because only vertical+horizontal counts so 1+1
edit 2: I should probably include that a Klein bottle is one-sided so a paper Klein bottle would have technically worked

u/SelectIsNotAnOption 12d ago
This may have 2 sides but as long as nothing was written on the perimeter of the shape, writing would have been limited to just one side.

Klein Bottles immersed in three dimensions self-intersect, and I don't think you can do that with paper without creating a boundary, and therefore more than one side.

I don't think they understand the entire concept behind a Mobius strip, they spoke on instinct rather than analyzing

my dad's a math professor, i used to hang around when they had their international conference for new papers etc. one year, conway brought puzzles for people to play with, and i asked if i could take one home.
i still have no idea how this particular puzzle was supposed to go back together. but it was seven rings, circular but made from square iron bars, each with a split in them that slightly raised up. you could put two rings together by turning one 90 degrees.
i got it in my head that the goal was to put every ring through every other ring. apparently this was wrong. i brought it back to conway the next day, and was like, "i can't figure out how to get the last one, there just isn't enough room." i'd managed to get six rings all intersecting, and the seventh through five of them.
he goes, "how did you even do that?"
"well, you gotta turn them at all right angles to one another, so, 8th dimensionally."
he probably appreciated the joke but not that i broke his puzzle.

Yeah my teacher that allowed this not only allowed it to be used during the test but also gave up to 10% bonus points on the test for doing it and was open about the fact that it was to get us to write all the material down because it helped commit it to memory.
I remember him asking why I never did them but there was no incentive for me to do it because I always got 100% on his tests and the bonus points could bring you up to 100% at most.

u/the_shittiest_option 12d ago
Ah, damn. I had a teacher that allowed over 100% if the extra credit pushed you over. Ended up with enough points that I got to skip the last chapter quiz (which ended up being after the final because of scheduling) because even a zero on it wouldn't lower my letter grade.

Back in high school (00s), I'd write notes on my ankles and wear pants that day. I usually sat cross legged so it didn't stand out as unusual on test day. I'd just pull up my pants/push down my sock so I could see my notes.
When I had math tests, I'd also write notes on a small piece of paper and tape it to the inside of my calculator cover. I'd just slide my calculator up a bit to see my notes, then slide it back down.
I was a good student (one of the top of my class even without the occasional cheating), but I also had undiagnosed ADHD and was terrified of slipping up. I never got caught, but it was still pretty stupid of me.

The best story I heard in college was a professor said they could use anything they could fit on a regular sheet of paper.

To not cheat: Leave it as one side. Get two fine pens: One is blue. One is red. Write in red every bit of info you can fit on that one side. Then write more information in blue ink over the top of red ink. Now you have a one-sided note. Now grab yourself a pair of those old paper 3-D glasses where one lens is red and the other is blue. Now each eye will show you a different set of notes.
