1. Get some Borax and dissolve it in a bowl of water. This is your boric
acid solution. (Don't go hog wild with the Borax, either -- one teaspoon

2. Squeeze some Elmer's School Glue into the bowl of dissolved Borax.
3. Put on a pair of rubber gloves and mix it all up.
The boric acid will cause the glue to cross link, yielding ersatz Gak.
