Get a bowl to mix your slime ingredients in.
Pour your entire 6 oz Elmer’s Glitter glue into the bowl.
Add your baking soda and mix in thoroughly. Also add up to 1/4 cup of water here if you want a more stretchy slime.
Slowly add in your contact lens solution (reminder: your contact lens solution should contain boric acid or your slime will not form). Add it in slowly and mix if possible so that you can adjust and ensure you do not add too much. You may not need the full amount so take this step slowly.
Now mix until your slime forms and begins to harden. Take it out and knead, knead, knead. You may be surprised how much you need to knead to really make the slime form. If it’s not the desirable consistency keep kneading. If you find it to still be too sticky, add a little bit of lotion or baby oil to your hands.
