I have a sweet LEGO Santa Claus and few other builds that would look cool as decorations on Christmas Tree. Sadly, it would probably break if I would try to hang it. It can stand all right, but is not sturdy enough to hang, or to survive much handling, really.
So I want to glue it together. But I don't want it to stay glued. I want to be able do disassemble it when I no longer use it as ornament that hangs on something. Is there any way to glue LEGO bricks and still be able to wash away the glue without damaging them when I want to?
Note: this question has nothing to do with safety of 4 years old kids, like this one, and strength of connection I'm asking about is way smaller (hanging on a tree vs kid potentially trying to take it apart).
