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.

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.

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 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

Not a scam.

Also, your breath might help in a pinch (it's humid).

The best CA accelerator I know is baking soda.
