To make this Grinch you will need water, white school glue, borax, and green food coloring.
First in one bowl dump a bottle of school glue. (we used a 4oz bottle.) then fill it with warm water and dump that in to. Add some green food coloring and mix well.
In another bowl mix about half cup of water with teaspoon of borax.
Once both are mixed well slowly pour the borax water into the glue water and mix.
Mix till slime forms.
Note~ you could also add some small toys to the slime for extended play. Just remember to have fun!
