We like fluffy slime because it has less mess than other traditional borax slime recipes. We use our best fluffy slime recipe as the base for this slime, but we add pastel galaxy colors for extra pizazz!

What is Galaxy Slime?

Galaxy slime is simply a slime that uses the colors of the galaxy.

Even though space is technically black, we usually think of a galaxy as being filled with brilliant colors and sparkling lights.

This version of galaxy slime uses pastel colors and is just the prettiest version of a milky way galaxy!

This fluffy galaxy slime recipe is easy to make! No borax and made with laundry starch and shaving cream. Mess-free and super satisfying!

Why is My Slime Watery?

Watery slime usually means you messed up the ratio, but it’s usually completely fixable. If your slime is too watery, try this:

  1. Add more activator. It could be you just didn’t add enough activator!
  2. Pour off excess liquid. It could be that you added too much water or activator and need to pour off some access.

If that doesn’t work, try adding a bit more glue.

Why is My Slime Sticky?

Sticky slime usually means you don’t have enough activator. Try adding a bit more.

If that doens’t work, you may need to add something dry, like cornstarch, to help reduce how sticky your slime is. I like to add either cornstarch or shaving cream to eliminate stickiness.

The best fluffy galaxy slime for slime lovers. 3 ingredients and easy enough for kids to make alone! Super satisfying and stretchy!

Make this super easy pastel fluffy galaxy slime and transform your slime making into an exciting, colorful experience with less mess!


  • Elmer's white glue
  • Shaving Cream
  • Laundry Starch


  • Mixing bowls
  • Measuring cups and spoons
  • Stirring spoon


  1. Add one cup of glue to a mixing bowl.
  2. Add one cup of shaving cream to the bowl and stir. Be careful to stir gently or your slime will be less fluffy in the end.
  3. Add 1/2 a cup of laundry starch and stir gently.
  4. Your slime will start to form, but it might become stringy. If it does, don't panic.
  5. Let the slime sit for about 5 minutes.
  6. Evaluate your slime for texture and feel. If it's too sticky, add more laundry starch. If it is too stiff, add in a bit more shaving cream.
  7. Knead your slime for 3-4 minutes and evaluate again. Usually, the slime will be perfect and no sticky at all at this point. If it is, keep adjusting a little bit at a time until it has the texture you want!


Temperature and the moisture level in your area can change how much of each ingredient you need to include. Use our recipe as a guideline and make your own adjustments as you go! It's normal for there to be variations.
