Here’s a safe, easy, and kid‑friendly way to make slime at home, plus a few fun variations and tips.

How Do You Make Slime?

You can make classic school‑glue slime with just glue, baking soda, and contact lens solution.
No borax powder needed, and it comes together in a few minutes if you measure carefully.

Basic Glue Slime (No Borax Powder)

Ingredients

  • 1 bottle (about 4 oz / 120 ml) of white school glue
  • 1 tablespoon baking soda
  • 1½–2 tablespoons contact lens solution (must say “boric acid” or “borate” in ingredients)
  • Optional: a few drops of food coloring
  • Optional: glitter or small foam beads

Tools

  • 1 mixing bowl
  • 1 spoon or spatula
  • Airtight container or zip bag for storage

Step‑by‑step

  1. Add glue to the bowl
    • Squeeze the whole bottle of glue into the bowl.
    • If you want colored slime, stir in 2–3 drops of food coloring now so the color mixes evenly.
  2. Mix in baking soda
    • Sprinkle in 1 tablespoon of baking soda.
    • Stir until the glue and baking soda are fully combined and smooth.
    • This helps thicken the slime and keeps it from being too sticky.
  3. Add contact solution (the activator)
    • Start with 1½ tablespoons of contact solution.
    • Stir well; you should see the slime start to pull away from the sides of the bowl and clump together.
    • If it’s still very sticky, add a little more solution (about ½ tablespoon at a time), mixing after each addition.
    • Stop when it holds together but can still stretch.
  4. Knead the slime
    • Put a small squirt of contact solution on your hands.
    • Take the slime out of the bowl and knead it like dough for 2–3 minutes.
    • It will feel sticky at first but will become stretchy and smooth as you work it.
  5. Adjust texture
    • Too sticky? Add a few more drops of contact solution and knead again.
    • Too stiff or rubbery? You’ve added a bit too much activator; knead it longer, or mix in a teaspoon of plain glue to soften it.
  6. Store it properly
    • Keep your slime in an airtight container or zip bag when not using it.
    • If it dries out, you can often revive it with a small amount of glue and gentle kneading.

Fluffy Slime Variation

Fluffy slime is extra light and pillowy because of shaving cream.

Extra Ingredients

  • 3 cups foaming shaving cream
  • Same glue, baking soda, and contact solution as above

Steps

  1. Add about 3 cups of shaving cream to your bowl.
  2. Pour in ½ cup of white school glue and mix gently.
  3. Stir in ½ teaspoon baking soda.
  4. Add food coloring if you like pastel, cloud‑like colors.
  5. Add 1 tablespoon of contact solution and stir quickly.
  6. When it pulls together, knead it with your hands until it’s stretchy and fluffy.

Fluffy slime doesn’t last as long; after about a day, the shaving cream deflates and it becomes less fluffy.

Clear, Glitter, and “Aesthetic” Slime Ideas

Once you can make basic slime, you can remix it into fun styles:

  • Clear slime: Use clear glue instead of white glue, skip shaving cream, and add activator slowly so it stays translucent.
  • Glitter slime: Make basic or clear slime, then knead in glitter at the end so it doesn’t scratch the bowl.
  • Galaxy slime: Use clear glue, dark blue or purple coloring, and silver/purple glitter. Swirl colors lightly instead of fully mixing.
  • Crunchy slime: Mix in foam beads or plastic “fishbowl” beads for a crackly sound when you press it.

Always add decorations last so they don’t interfere with the glue and activator mixing.

Safety Tips (Important)

  • Only use washable school glue and contact solution made for eyes (check the label for boric acid/borate).
  • Don’t use straight borax powder or other strong chemicals; they can irritate skin and eyes.
  • Wash hands before and after playing with slime.
  • Don’t eat slime or let pets chew on it.
  • If anyone has sensitive skin, try wearing disposable gloves and keep playtime shorter.

Simple “Story” Version for Kids

You pour glue in a bowl, sprinkle in baking soda, then add a magic liquid (contact solution).
At first it looks like a mess, but as you stir and squish it with your hands, it turns from sticky goo into stretchy slime you can poke, swirl, and stretch like melted cheese on pizza.
The more you squish it, the smoother and stretchier it gets—like your own little science experiment you can play with.

Quick HTML Table of Ingredients

Slime Type Main Ingredients Texture
Basic glue slime White glue, baking soda, contact solution, optional food coloring Stretchy, slightly sticky at first, then smooth after kneading
Fluffy slime White glue, shaving cream, baking soda, contact solution Light, airy, pillowy, not very transparent
Clear/glitter slime Clear glue, baking soda, contact solution, glitter Glossy, see‑through, sparkly with glitter

Tiny FAQ

  • How do you make slime less sticky?
    Add a few drops of contact solution at a time and knead until it pulls cleanly off your hands.

  • How long does slime last?
    In an airtight container, basic slime can last several days to a couple of weeks; fluffy slime usually only keeps its texture for about a day.

TL;DR:
To make simple slime, mix 1 bottle of white glue with 1 tablespoon baking soda, then slowly stir in 1½–2 tablespoons contact solution until it forms a stretchy ball, and knead it until smooth.
