What This Craft Means

Galaxy Slime gives kids a tactile, cosmic creation experience. By blending deep shades of blue, purple, and black with metallic glitters, each child crafts a swirl of “outer space” inside a sealed glass or plastic jar.

Materials Required

  • Clear PVA glue (4 oz per child)
  • Warm water & liquid starch (or contact lens solution + baking soda)
  • Fine glitter (silver, cosmic blue, deep purple)
  • Dark liquid watercolors or food coloring (navy blue, deep purple, black)
  • Airtight 8 oz plastic or glass jars with custom labels

Step-by-Step Instructions

  1. Mix the Base: Pour 4 oz of clear glue into a plastic bowl. Stir in 2 tablespoons of warm water to loosen the consistency.
  2. Color the Stars: Add 2–3 drops of navy blue or deep purple liquid watercolor. Stir until fully blended.
  3. Add the Starlight: Generously sprinkle silver and purple glitter into the mixture.
  4. Activate the Slime: Slowly add 1 tablespoon of liquid starch while stirring continuously. Once the mixture pulls away from the bowl edges, knead it by hand for 2–3 minutes until smooth and non-sticky.
  5. Layer and Store: Repeat the process in separate small bowls with different colors, then twist the colors together gently and transfer into the storage jar.

Pro Tips & Creative Variations

  • Glow-in-the-Dark Boost: Stir 1/2 teaspoon of glowing zinc sulfide powder into the glue base before activating for night-glow slime.
  • Mini Alien Figures: Drop tiny plastic alien figurines into the jars for an extra surprise element.

Mistakes to Avoid

Avoid using white school glue if you want a translucent space effect; clear PVA glue produces deep contrast for glitters. Do not add contact lens solution without baking soda, or the slime will fail to activate properly.
