To make glow in the dark putty, you need a half cup of liquid starch, a half cup of white school glue, neon green food coloring, and 1 tablespoon of glow in the dark paint.
Pour all of the ingredients together and stir!
We had SO much fun, and I'm so glad to finally make putty again! (O and I followed this recipe to make putty a few years ago, but we haven't made it since then because I was afraid that E would eat it. Don't let kids who still put things in their mouths play with this putty as I'm pretty sure the liquid starch is dangerous if ingested.)
