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.

    • 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).

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.
