Superglue won’t leach any nasties?Superglue (cyanoacrylate) or string, take your pick.
Cyanoacrylate has a stable bond with water. So after it dries, it's ok.Superglue won’t leach any nasties?
I can personally attest that it's very easy. I wouldn't even try liquid glue.I haven't used it personally, but members report the gel superglue easier to work with than the liquid type, which runs where you don't want it and turns white when wet. The gel type stays where you want it (unless you are a messy person)
