Homemade Noise Putty
1 1/2 tsp. borax powder
Mix glue with water in a large bowl. Add a couple of drops of food coloring if desired. Set aside. In a small bowl, mix warm water with Borax. Add to glue/water mixture and stir for 2 minutes. It will go from liquid to a nasty stringy mass, then at the end of 2 minutes it will be putty! Knead to smooth putty out.
Stuff putty into a small cup (friction makes the noises).
