Replacing a broken set of blinds in my house and apparently no one sells the old standard kind where you pull the cord to raise them, I guess because kids and/or pets could tangle in the cord? Bit of an education in miniblinds today.

    Take two pieces of string with wooden knobs at the ends and hang them up together.

    Put your arm between them and pull down quickly.

    Repeat, and notice how a fraction of the time those wooden knobs may wrap around each other and become tied by a knot held by the downward force of your arm until you pull up which you can’t do if you’re hanging.
