Slime Recipe Science Lab Activity
Set up a slime lab where your child measures, mixes, and experiments with different slime recipes — part chemistry experiment, part tactile paradise.
What You'll Need
- 1Clear school glue
- 2White school glue
- 3Shaving cream
- 4Contact lens solution (with boric acid)
- 5Food coloring
- 6Measuring cups and spoons
- 7Mixing bowls
- 8Recipe cards
What You'll Need
Clear school glue and white school glue
Shaving cream
Contact lens solution (must contain boric acid)
Food coloring
Measuring cups and spoons
Mixing bowls
Simple recipe cards
How to Play
Set up a lab station with ingredients, tools, and recipe cards laid out like a real science lab.
Give your child the base recipe: 1/2 cup glue + coloring + 1 tablespoon contact lens solution.
Let them measure, pour, and stir. The measuring practice alone is worth it.
Show them how to stir until the slime forms and pulls cleanly away from the bowl.
Knead until smooth — this takes patience and hand strength.
Now the real science begins: "What if we use clear glue instead? What if we add shaving cream?"
Label each batch, line them up, and compare textures, stretchiness, and appearance.
Tips
This is genuine experimental science — your child changes one variable at a time and observes what happens.
Write predictions before each modification: "I think adding shaving cream will make it fluffier." Check after.
Contact lens solution activates the slime by cross-linking the glue polymers. Real chemistry!
Keep wipes and a bowl of warm water nearby — slime residue cleans up easily before it dries.
Not taste-safe. This is appropriate for children who no longer mouth materials.
