This homemade Galaxy Slime is straightforward to prepare, using just a handful of ingredients. This recipe comes with several possibilities for a variety of colors and overall looks! Mix and match away!


  • 1 bottle clear glue
  • 1/2 tablespoon baking soda
  • A few drops of liquid watercolors
  • Glitter
  • 1 1/4 tablespoons contact lens solution


  1. Pour the glue into a large glass bowl. To capture the last of the glue, put the cap back on, prop the bottle upside down, and move on to the next step.
  2. Add the baking soda and stir together.
  3. Add a few drops liquid watercolors. Stir again. Add any remaining glue that pooled in the bottle and stir until evenly blended.
  4. Sprinkle in glitter. How much you add will depend on personal preference. Add a little at a time and stir to make sure the glitter doesn’t thicken the slime too much.
  5. Pour in the contact lens solution. If in doubt, add just under one tablespoon, stir until evenly blended and then knead by hand until slime forms. If the slime is still too sticky, then add another 1/4-1/2 tablespoon contact lens solution and continue kneading.
  6. Knead by hand until slime forms and then start to PLAY! Store slime in an airtight container or baggie for several days.


  • Regular or fine glitter will work, however they will work differently. Fine glitter will make the same iridescent while the coarser regular glitter will stand out more.
  • White and silver glitters work well as starter colors.
  • If the bottle of glue is less than 5 ounces, reduce contact lens solution to approximately 1 tablespoon, knead the ingredients together, and add more solution only if the slime is still too sticky.
  • White school glue works, too, and will provide pastel galaxy colors.
  • I like to line a table with parchment or foil so the slime doesn’t stick to surfaces or make them wet, and the slime stays fresher by not absorbing whatever is around it (including unseen crumbs on the kitchen table).
