Add the red paint, water, baking soda, red glitter and 3 tablespoons of contact solution to the bowl. Mix well.
Once the mixture begins to stick to itself, use your hands to knead and stretch the slime.
If your mixture is still too sticky to form slime, slowly add more contact lens solution. Knead again and continue adding more contact solution until your desired consistency is achieved.
Repeat steps 1-4 again with the blue paint and blue glitter.
Notes
Your contact lens solution must contain boric acid in order to make this slime, so check the ingredients before purchasing.
