Ooh, like when a bottle of Krazy Glue dries out? I kinda hope so...

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.

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'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.

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.

Had to look that up. Pretty cool. Would've expected it to be more cloudy. https://www.reddit.com/r/mildyinteresting/comments/1ogb2k3/m...

I expect something with a lot of small bubbles and cracks, also it also overheated and got weird decomposition and reactions, something like a overcooked/toasted meal. Reusing a comment that I made in a previous thread:

For comparison, there is a nice video by NileRed https://www.youtube.com/watch?v=phNLecfyWS8 He is making Bakelite that is a type of plastic. It's a tiny amount, in a lab, on purpose and he may make a few attempts. Anyway it overheat and instead of a nice piece of plastic he got a nasty block of foam with burned plastic. No imagine a huge tank of a similar chemistry reaction.

A contractor showed me how to fix dents in granite with superglue. It’s totally clear. The trick is to scrape it with a razor blade at a 90 degree angle (strait horizontal). The imperfections become nearly invisible.

This is also how glass chip repair works. If the polymer has a close enough index of refraction to the glass, it's invisible.

I've been told this is a cheap way to fix small windshield cracks. Never tried it but sounds like it would work for the small spider sized and shaped cracks from small rock impacts.

This is basically what the glass repair kits sold at auto parts stores are. (They also include a suction cup with syringe, to vacuum any air bubbles out.)

And, bringing this topic full circle, the chemical in those kits is methyl methacrylate!

The expensive way is superglue plus a little suction cup to evacuate the air, and a razor blade.

The KRAGLE!
