David R, I am not convinced Elmer's will give up when wet. Years ago I was working on a couple small furniture projects for the house. Had quite a few scraps of Honduras Mahogany left over and decided to cut them in to toy blocks of various sizes for my 3 year old daughter to play with. I spent a couple hours cutting and sanding them real nice for her. Couple days later she got ahold of the Elmer's ,and having watched me gluing up the furniture, decided to glue up her blocks in one big stack. I soaked them in water for several days and they never did come apart. She arranged them such I couldn't even saw them apart without ruining most of them. Made her another stack later.
