Patterned toothpaste

multidimensional patterns, that is.

So striped toothpaste exists already - this relies on uniform rheology of the paste (its thickness and spreading properties), and filling the tube with even pressure.

But surely we can do better - it's almost the future already.
I propose the creation of patterned toothpaste, and with technological development perhaps even toothpastes with a picture all the way through, like seaside rock.

Polka dots may be a good place to start.

Filling tubes with color strips at the 4 minute mark [a1, Oct 02 2022]


       + Only if you can make plaid.

       Totally unnecessary, would require complex internal structure and possibly valving. [+]

       The unaboner doesn't brush.   

       Why stop at color when shape is just around the corner? What better way of getting kids excited about brushing their teeth before bed than extruding a tiny, perfectly formed different dinosaur every night?

       Can this dinosaur extrusion technology not be extended to cheese wiz and peanut butter?

       [+] It wouldn’t be difficult to get patterns instead of regular stripes. Pictures all the way through or dinosaurs might be a stretch, but simple patterns like polka dots should be easy. I read some reddit threads and watched a couple of youtube videos (linked) on how they fill the tubes now, so I know what I’m talking about.

       Ah the ten minute Wikipedia degree: a marvel of our age.

       3d-print every serving, with 3 or 4-colors of tubes with nozzles. Sell the refills like inkjet printer ink. Make a fortune.

       Ooh, I didn’t check Wikipedia yet - was saving that for advanced research.

       I try not to care about bones but just curious about this one. This is a great idea, admittedly with some challenges, but that's what makes it interesting. Criticism will be considered respectfully from me at least, but just curious.   

       As suggested, 3d printing would do this very easily, but could you just have one continuous tube pushed like a syringe to keep it all in place and not mixed? [+] anyway.
