Empty the entire bottle of glitter glue into a mixing bowl. If using a larger bottle, measure ¾ cup.
Stir in ½ tablespoon of baking soda until fully combined.
Add 1 tablespoon of contact solution while stirring. Slime will begin to form and pull away from the bowl. If still sticky, wait 3–4 minutes, then add a little more solution.
Remove slime from the bowl and knead until stretchy. If too sticky, add contact solution a few drops at a time. If too stiff, knead in a small amount of water.
Sprinkle in extra glitter or add slime charms, then knead to mix.
Stretch, squish, and have fun with your glitter glue slime!
Notes
The contact lens solution must contain boric acid or sodium borate.
