YSK: Flossing your teeth is only uncomfortable when your gums are unhealthy

Jump

  • They've got you strapped down into that chair naked

    Idk about you, but my clothes stay on at the dentist

    • Can we settle this: how many holes does a straw have?

  • Just copying my response to another comment asking the same:

    That doesn't change the topology though. Or at least you can't without it no longer being a straw.

    A straw is the product of a circle and an interval. Either the knot doesn't fully seal the interval, meaning it's topology is maintained, or you completely seal the straw, changing it from 1 long interval to 2 separate intervals, changing the object entirely.

    In this situation, the straw would not be completely sealed. It is clearly inefficient, but technically there exists a path for which there is a level of force that could applied that would make the straw function.
