🟢 HOMEMADE SLIME
🧪 YOUR LAB CHECKLIST
Science buddy, grab a grown-up before you handle borax or pour glue. Cover the table with newspaper or a mat. This comic explains why goo becomes stretchy slime.
- 🧴 White school glue (PVA): about half a cup, the classic polymer starter
- 🥄 Borax powder: one teaspoon dissolved in one cup of warm water (activator solution)
- 💧 Water: a splash to thin glue if it feels too stiff
- 🎨 Optional: food coloring or glitter for personality (add before mixing activator)
- 🥣 Mixing bowl, spoon, and zip bag for kneading and storage
Time: about 30 min · Adult supervision required · One palm-sized batch of slime, stored in a sealed bag when done

POLYMER POWER
MOLECULE NOODLES
White school glue is mostly water carrying long plastic-like molecules called polymers. Picture each polymer as a noodle that can slide past neighbors when the glue is liquid. Polymers show up everywhere: in rubber bands, plastic bottles, and even DNA inside your cells. Slime happens when something links those noodles together so they still move, but as one big tangled web. That web is soft enough to pour yet springy enough to stretch.

GLUE
🧴 PVA glue holds polymer chains waiting to be connected.
CHAIN
🔗 Many small units snap together into one super-long strand.
