Galaxy Slime Recipe

This Galaxy Slime is out of this world. You can play around with colours for various effects.

Time : Mixing 15 minutes and settling 2 to 3 days, however you can play with your slime immediately. Settling is needed for bubbles to disappear.

Difficulty : Easy


  • Slime Glue - 1 and 1/2 Cups (1/2 a cup per colour)
  • Slime Glue Activator - as needed for chosen consistency
  • Food Colouring - Blue, Purple, Pink
  • Glitter - Lots. Any colours you like. We think Holographic or Silver glitter mixed with Black glitter give a nice effect
  • Small Star Confetti - Optional


  • Clean work surface
  • 3 x Large clean mixing bowl
  • 3 x Mixing spoons and or spatulas
  • Large flat airtight container


  1. You are going to make 3 separate batches of slime
  2. Pour 1/2 cup Slime Glue into each mixing bowl.
  3. Add a different drop of food colouring to each bowl and mix well.
  4. Add glitter to each bowl and mix well.
  5. Add Slime Glue Activator, in little squirts at a time. Do not add too much as it will make your slime hard instead of stretchy.
  6. Mix slime with spoon or spatula until it comes together.
  7. Knead and stretch the slime with your hands, for a couple of minutes, until your desired consistency is reached.
  8. Carefully twist your 3 different coloured slimes together and store inside your airtight container.


  • Always mix thoroughly, especially before adding more Slime Glue Activator.
  • Only add more Slime Glue Activator if absolutely necessary (1 - 2 teaspoons per time)
  • Add extra drops of food colouring for a darker colour. Slime too hard? Add more Slime Glue.
  • Slime too sticky? Add more Slime Glue Activator.
  • A large flat container works best, because the thinner your slime level, the quicker the bubbles will disappear.
  • Wash your hands well before playing with your clear slime, so you don't get it dirty!
  • Always wash your hands after playing with slime.
