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.
