You're of course correct about how these packets are produced. The reason was originally that the inner part of the tube could be kept aseptic/sterile throughout the process, as only two ends of the tube would ever be open at the same time, and could easily be controlled, and it was also very simple mechanically. It was invented at a time when most milk was sold on tap or in sealed glass bottles.

Oh nice, thanks for confirming my wild speculation with a cool fun fact :)

It's also probably one of the most efficient shapes for packaging tiny amounts of milk, like these single serving coffee milk packets, in terms of avoiding spilling milk. I assume as long as the tube of milk is crimped with a rolling motion that avoids trapping it under pressure but just pushes it forward into the uncrimped end you have less spill per packet than any other shape that requires several folds during production. And also tiny packets are hard to open without spilling but if the opening is on a pointy end you can more easily open it over your cup without spilling much. The shape is also less likely to flatten by pinching it than a rectangular carton is when you opening it. Oh, and the mechanism for creating this shape is way simpler than any folding carton design too.

These flexahedron are also called kaleidocycles. There is a book by Doris Schattschneider and Wallace Walker with cardboard ones, decorated with M.C. Escher patterns, to assemble. Including the weird Moebius like ones.

milk in a bag is just milk balls that haven't been filled to their maximum potential volume... which is probably for the best, actually. Imagine the smell in the dairy isle if we sold milk in what would ostensibly be water balloons.

Remember Jubbly lollies? I think the oat milk carton is the same 'shape' as those. Something like a scalene tetrahedron or some sort of di-sphenoid. The good stuff!

Fascinating video, thank you! I hadn't encountered Truchet tiles before, so I think I'm about to make a nice discovery :) By the way, I remember, I think, drinking milk at school from one of these tetrahedron shapes, after poking a straw through the hole (I was a kid in 1970s England). It could be a false memory, but I'm reasonably confident it isn't. I think we also had small bottles of milk, but I don't remember which came first - probably the bottles. It was provided free as a government policy at the time.

Very late to this, but enjoyed it a lot. Two things: 1. I think that you have to consider not only efficiency of production, but packing efficiency in shipping lots of them in a box. :-) 2: Are you familiar with beaded kaleidocycles? Some of the ones in the Contemporary Geometric Beadwork project are just stunning. I don't know if anyone has made a mobius one, though.

"the volume is maintained...." But is it? In the mid flex state, I intuit that the volume is different. I wonder..
@stiofanmacamhalghaidhau765 27 күн бұрын
I think it is. two sides are in motion at once, and essentially the volume changes shape/position but the internal volume stays the same. its a good question tho - is this the same at the end points or continuously?

you're a really smart gal' and so much style charisma and attitude! you are the definition of amazing. no lie keep it going. Life is just a big pond(or surface of zero friction liquad with no air resistence) and we are the ripples (caused by quantum fluxuations in the liquad)! god is the light (that comes from the ether) that reflects our surface, back into the ether. So you can imagine the interactions, randomness and entangledmentations that would result in something so crazy yet utterly impossible to recreate even if one was to spend an enternity.
