Help!?
What can we use if we can't find contact lens solution?
If you don't have contact lens solution, an adult can use 1 tablespoon liquid starch or a borax activator (1/4 teaspoon borax dissolved in 1 tablespoon water) instead of the 1 tablespoon contact lens solution when activating the 1/2 cup glue.
Why doesn't the slime pull away from the bowl or keeps feeling sticky?
If the mixture doesn't pull away during the 30–60 second stirring step or remains sticky after kneading, ask an adult to add an extra 1/4 teaspoon contact lens solution and knead, and if it becomes too firm ask an adult to add a pinch of baking soda and knead as the instructions suggest.
How can we change the activity for younger or older kids?
For younger kids, have an adult pour the 1/2 cup glue, add 1–2 drops of food coloring, and let them gently knead the slime on the disposable mat, while older kids can measure the 1/2 teaspoon baking soda themselves, experiment with the 30–60 second stir time, or add mix-ins during kneading to compare stretchiness.
How can we make the slime more fun or unique?
After you remove and knead the slimy blob, personalize it by mixing in glitter, foam beads, or small sequins, try combining two different colored batches before testing stretch, and then share a photo of your colorful creation on DIY.org as suggested.

Facts about kid-friendly chemistry
🧪 Slime is made from polymers — school glue contains polyvinyl acetate, which links up to form stretchy chains.
🎨 A few drops of food coloring or a sprinkle of glitter can turn one slime recipe into endless colorful creations.
🧂 Baking soda (sodium bicarbonate) helps firm slime, while contact lens solution provides borate ions that cross-link the glue.
✋ Slime acts like a non-Newtonian fluid: move it slowly and it flows, tug it quickly and it can snap like a solid.
🧼 Always make and play with slime with an adult nearby, wash hands after, and never taste or put slime in your mouth.
