8 oz. white craft glue
1 cup water
Poster or tempera paint (in a nice slimy color, try mixing colors for a truly icky shade)
1 cup warm water
1 ½ tsp. borax powder (available in supermarkets in the laundry soap section)
Pour the glue into a large bowl. Add 1 cup water and stir until the glue and water blend. Add a few drops of paint, and stir some more until it’s mixed well. Set aside.
In a small bowl, stir together the warm water and borax powder until the powder dissolves. Slowly pour the borax and water into the glue mixture, stirring constantly for two minutes.
The fun part: Knead the sticky Gloop with your hands until it’s smooth and stretchy. When you’re done playing with it, store it in an air tight container
