2 tablespoons contact lens solution, plus more if needed
Liquid watercolors or food coloring, optional
2 rounded cupfuls of regular foam shaving cream, plus more if needed
Baking soda, optional
In a large mixing bowl, combine one 4-ounce bottle of white school glue and add two tablespoons contact lens solution. If you are planning to color your Fluffy Slime, then add either food coloring or liquid watercolors at this stage. Stir ingredients together until well blended.
Add two rounded cups of regular foam shaving cream to the mixture and stir vigorously as much as possible. As you stir, the mixture should start pulling away from the sides of the bowl, turning into a blob. Use a spatula to scrape the sides of the bowl to capture any of the mixture that didn’t blend into the blob. The more you stir, the more like Fluffy Slime it will become.
Once you’ve stirred as much as you can with a spoon or a table knife, then begin kneading the slime between your hands. At first the mixture may stick to your hands and fingers, but as you knead, stretch, and pull the blob, it will gradually form into Fluffy Slime. If it is still too sticky, then add another quirt of two of contact lens solution, kneading in between each addition, until the desired consistency is reached.
