How to Make Galaxy Slime

Galaxies are a dazzling sight to many, and slime is a fun and useful “toy” that many enjoy playing with. Why not combine the two and create a fun slime that also looks quite neat? A sparkly and stretchy slime that reminds you of the universe is both fun to make and stretch, and squish, and poke!


  • 360 millilitres (13 imp fl oz; 12  fl oz) clear liquid glue (white glue is a substitute for it, but the clear glue looks better)
  • 300 millilitres (11 imp fl oz; 10  fl oz) water
  • Dark blue food coloring
  • Black food coloring
  • Pink food coloring
  • Purple food coloring
  • Fine glitter
  • Regular glitter


  1. 1
    Add 1 teaspoon (4.9 ml) of borax to 500 millilitres (18 imp fl oz; 17  fl oz) of hot water. Stir it thoroughly and then set it aside to cool.
  2. to Make Galaxy Slime
    Separate the glue into three bowls. Pour about 120 millilitres (4.2 imp fl oz; 4.1  fl oz) of clear glue into each bowl.
  3. to Make Galaxy Slime
    Pour 100 millilitres (3.5 imp fl oz; 3.4  fl oz) of water into each bowl.
  4. to Make Galaxy Slime
    Add both the blue and black food coloring into one bowl.
  5. to Make Galaxy Slime
    Add the pink food coloring into the second bowl.
  6. to Make Galaxy Slime
    Add the purple food coloring into the third bowl.
  7. to Make Galaxy Slime
    Shake both types of glitter into each bowl.
  8. to Make Galaxy Slime
    Use a stick to combine the glue, water, food coloring, and glitter. When fully combined, the glue, glitter, and color will be evenly dispersed, and won’t “clump” in certain areas.

    • It’s possible to mix with a spoon, but it’s not recommended. The mixture can cling to the curve of the spoon and be hard to get out.
  9. to Make Galaxy Slime
    Pour a third of the borax mixture into one bowl. Stir quickly and thoroughly as the slime begins to stick together.
  10. to Make Galaxy Slime
    Repeat with the other two slime mixtures.
  11. to Make Galaxy Slime
    Knead the slime with your hands. At this point, if the slime is still fairly watery, knead it with your hands to help it gain a more solid shape.
  12. to Make Galaxy Slime
    Carefully combine the slimes by kneading them together. Don’t blend them too much, or they’ll end up losing their color.
  13. to Make Galaxy Slime
    Play with your sparkly galaxy slime. Store it in an airtight container or plastic bag.

  • Will the borax burn my hands?
    wikiHow Contributor
    No, but you should wash your hands afterwards. If you have especially sensitive skin, you could wear gloves as a precaution.

  • What does the borax do?
    wikiHow Contributor
    The borax is what gives the slime its proper consistency. That being said, it is possible for you to make slime without borax as well.

  • Do I need to use borax?
    Lillian Padilla
    No, you can use liquid starch or laundry detergent. Borax makes the slime stiffer.

  • How do I get food coloring off my hands?
    wikiHow Contributor
    Wash with soap and water, or try rinsing them with white vinegar. If nothing works, it will come off on its own in 2-3 days.

  • Where can I find black food coloring?
    Buy red, blue and green food colouring, mix them to make a dark grey colouring. It’s as close as you can get to black.

  • If I want to make it fluffy, what do I do?
    wikiHow Contributor
    You could use shaving cream. It may change the color of your slime, but it will definitely add volume.

  • Can I substitute glitter for something else?
    wikiHow Contributor
    Yes, you can. Use some metallic food coloring or paint and very thoroughly mix it with salt. Once mixed, place some wax paper on a baking tin and spread the salt into a very thin layer on the wax paper. Preheat oven to 180 C or 360 F and bake for 10 minutes. I do not recommend this because the shape is not like glitter, it’s very tedious, and it wouldn’t work as well, but it’s better than nothing.

  • How do I prevent the colors from mixing together and becoming one color?
    wikiHow Contributor
    The colors are supposed to mix, but they will create the effect that represents a galaxy. If you’re worried about mixing the colors too much, just stop mixing if they start to blur together.

  • Do I have to use silver glitter?
    wikiHow Contributor
    No, that’s just done to make it look like stars. You can use whatever color you’d like.

  • Why would I make so much slime?
    wikiHow Contributor
    You can make as much as you want; if you’d like less, you can easily halve the recipe.

    • White glue will work if you don’t have clear glue, but isn’t preferred.
    • You don’t need to use borax. It’s possible to replace the borax solution with liquid starch, liquid laundry detergent, contact lens solution, or a saline solution.
    • Consider adding confetti stars to the slime for an extra-galactic appeal.
    • Don’t put in too much glue or it can make the slime overly sticky.


    • The colors will naturally blend together if you knead your slime a lot.
    • Glitter can be quite messy, and playing with this slime may cause glitter to scatter and get on your hands.
