One thing not mentioned but important is that superglue is very strong against tensile loads but not shearing ones. You can lift a car with six drops of it on the roof of it (see Myth Busters et al), but you can’t glue a 40 lb weight to the wall.
- _a_a_a_ 4y agoI'm very surprised at this and I wonder if it's not a failure of the shear strength of the glue, but of the surface of the wall. I'm pretty damn sure that plaster is a crap thing to attach directly to, ditto wallpaper, and rough raw brick while strong is far too uneven to expect much contact between it and the item glued.

- chubbnix 4y agoI think the shear strength is the weakness. I break super glued corals off their ceramic plugs for my aquarium and you can almost always get a perfect break by using flush cutters to slide the coral off the plug instead of trying to pry it off or cut it.
