Note that it doesn’t dry out; it polymerizes, and the reaction is catalyzed by water, which is why cyanoacrylate glues will stick your fingertips together instantly but will not as rapidly stick plastics or metals together.

There are superglue(CA) accelerators sold, is that just a big scam? Because as far as I can tell a spray bottle with water works just as well.

  I think Polyolefin Primer (Permabond POP) is magical in what it can superglue. Beautiful chemistry allowing something like Teflon or steel to be glued. https://www.youtube.com/watch?v=G9yz8OqThJk https://www.youtube.com/watch?v=G9yz8OqThJk

  Not a scam. Also, your breath might help in a pinch (it's humid).

  Water but it's a bit of hit and miss that can turn soggy, better is bicarbonate that triggers are more or less instant reaction (often in baking powder in a pinch, but that's mostly a waste compared to just bicarb). Often if one wants to make something "larger", dropping superglue, adding bicarb with a silt, blowing away and dropping another layer works fairly well (it's a bit of a brittle but still quite hard mass that is created quickly).

    I've rebuilt my old laptop's hinges this way, building up little by little, almost 3d printing crudely by hand. Then at some point I realized that I overdid it! Easy-peasy, a file and sandpaper to the rescue, I thought. Aand.. I spent x3 more time shaving off the excess than building it! It's super tough.

  The best CA accelerator I know is baking soda.

  They're made out of extremely cheap materials, so you're paying several times more for packaging and distribution than for the product. Then again, people pay to have water packaged and distributed, often when they have it on tap.
