What can we use if we don't have contact lens solution for the activator?
If contact lens solution isn't available, ask an adult to use 1 tablespoon of liquid starch as the activator in place of the contact lens solution in step 9 when mixing the glue and baking soda.
My slime is still sticky after stirring in the contact lens solution—what should I do?
If the mixture stays sticky after step 9, have an adult add the contact lens solution one drop at a time while stirring and then knead for 1 to 2 minutes until it pulls away from the bowl, or add a tiny pinch more baking soda to firm it up.
How can I adapt this slime activity for younger or older kids?
For younger children, have an adult pre-measure the 1/2 cup glue, 1/2 teaspoon baking soda, and 1 tablespoon contact lens solution and let the child do the stirring and kneading steps 7–11, while older kids can experiment with clear vs. white glue, different food-color amounts, or mixing in glitter and foam beads from step 12 for texture.
How can we make the slime more special or show-worthy before sharing on DIY.org?
To enhance the slime, make small colored batches by adding different food-color drops in step 8 and layer them together, or knead in a teaspoon of glow-in-the-dark paint or a drop of scented oil during step 12 for glowing or scented textures to photograph and share on DIY.org.

🧂 Baking soda helps adjust the mixture so it thickens, and many contact lens solutions contain borate ingredients that 'activate' slime by cross-linking PVA.
🧴 School glue is mostly polyvinyl acetate (PVA), a polymer whose long chains help slime become stretchy when they’re linked together.
🎥 Slime became a huge online trend—millions of videos show satisfying stretches, squishes, and ASMR-style sounds people love to watch.
🧪 Slime behaves like a non-Newtonian fluid—sometimes it flows like a liquid, sometimes it stretches like a solid.
