Start with 4 small bowls. Pour 4 oz. of clear school glue in each. In every bowl, add 1/2 tablespoon of baking soda; mix well. Once dissolved, add 3-5 drops of food coloring in each bowl, then stir. When that’s fully mixed, gradually add 10-15 drops of saline solution, a few droplets at a time. When the slime reaches a gooey state remove & knead with your hands. When all batches are ready lay on a flat surface & twist to create tie dye pattern.
