Super-glued? I didn't think Super-Glue was water-safe. Mine is tied with fishing line. Last week, I made the mistake of thinking it was secure enough to remove the line. Wrong. The moss had grown over the line so when I tried to remove it, I pulled up all the moss from the wood. Had to retie it.
Yes, super glue is super safe (lol) ... look for cyanoacrylate super glue or super glue gel (ie regular dollar store super glue). The gel is better, because it has a longer working time and doesn't drip everywhere.
I blame spelling mistakes on my iPad. You should too!
