    Are you posting the most recent one into the middle, or squooshing them up to fit them inside the most recent one?

    Nice! I also do this, but don’t think I’ve ever gotten to 12. 8 or 9 is probably my record.

    Edit: managed a 10 today 🙂

    have you found the ones with different sized paper cores? one time a few years ago, i had one inside another inside a third, they just slid over each other.

    There’s gotta be some math theorem about this.
    What would this fall under, topology I’m guessing?

      Probably just fairly bog standard geometry combined with some material science/engineering on the physical properties of the cardboard (such as how much it can compress/stretch)

      • Geometry: this problem more or less boils down to a 2d analysis since we need merely to look at a circular cross section. You could calculate the area each roll takes up by calculating the outer circle area minus the hole’s area, then divide the hole area by the ring’s area to get a theoretical maximum. This is assuming the material cannot stretch or compress. Not sure if this has a name, but it probably does.

      • Material science: Maybe you could measure the dimensions of a roll, stress test it in various ways, and re-measure the new dimensions to get a profile of how the cardboard warps. You could use that to get a better estimation of how much cardboard you can stuff into itself, but I’m not as sure on the details there.

    It would take me 2 years to get that many empty rolls.

    Washing asshole FTW.
