First off I found this forum by trying to figure out how Muta and others make their mist. I got so good ideas from here and I tried using the food coloring gimmick. It works great except that it can stain the skin.

I have heard that there is a gimmick that you can get from a magic supply or theatrical supply store that clips to a tooth and allows you to spray colored mist. Anyone know what this is called or where to get it?
