Supplies Needed for Unicorn Slime Recipe

Note: A quality glue is the secret to making perfect unicorn slime. It brings out the pastel colors that make this slime so beautiful and fun to play with.

Directions to make Unicorn Slime

Step 1

Empty a bottle of Elmer’s School Glue to a small bowl.

Step 2

Add 1/2 TBSP baking soda and stir until combined.

Step 3

Add 1 drop of food coloring to the mixture and stir.

  • You want a light, pastel color, so be sure not to add too much food coloring. We decided to make blue, green, yellow, purple, pink, and orange slime.
  • For the orange, we added 1 drop of red food coloring and 2 drops of yellow, but all other colors required just one drop.

Step 4

Pour in 1 TBSP contact solution and stir. The mixture will start to clump together and pull from the sides.

Step 5

Remove it from the bowl and knead it with your hands until it is no longer sticky and is pliable.

Step 6

Repeat with all of the colors, until you have six separate colors of slime.

If the slime remains sticky, you can sprinkle some more contact solution to the outside of it.

What Are the Ingredients to Unicorn Slime?

There are a lot of ways to make slime, but our slime includes the ingredients: Elmer’s School Glue, baking soda, contact solution, and food coloring.

How Do You Make Unicorn Slime Fluffy?

Follow the slime recipe carefully and you will love the way the slime feels.  Slime texture is one of the most important things when it comes to play.  You really want a slime consistency that you can’t help but touch.

What Colors Do You Need to Make Unicorn Slime?

Our unicorn slime recipe uses the following food color colors:  blue, green, yellow, purple, pink, and red.  You could go more traditional with the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.  Since you are probably using food coloring like we did, be aware that it is difficult to get really deep, saturated colors that don’t bleed onto your hands during play.

Is Elmer’s Glue Slime Safe?

Here is the information straight from Elmer’s website about Elmer’s Glue Slime Safety:

Elmer’s new slime recipes which are safe to make at home and include commonly used household ingredients such as baking soda and contact lens solution. Containing only trace amounts of boric acid, contact lens solution can be purchased over the counter and is regulated by the FDA. Baking soda is a common safe food ingredient.

Is Slime Safe for Toddlers?

Yes and no. We recommend using a recipe like this one that doesn’t have toxic ingredients like Borax, but that doesn’t mean it is edible or should be put in the toddler’s mouth.  If you have a child that usually puts things in their mouth, then an edible play dough is a better.

  1. Love these great ideas! My daughter has a youtube page and loves to do all sorts of fun stuff like this on there. I will be sure to share your blog!

  2. Does it HAVE to be Elmer’s brand of glue? Also, I read somewhere that you have to get contact solution that contains Boric Acid (Walmart brand works) maybe that would help the woman who commented above^

  3. Oh no! I don’t know why it would have done that… We used liquid food coloring and ours stayed colorful. Maybe try adding more food coloring to the mixture?

  4. Hello! My daughter and I had fun making this and I followed everything you said. Unfortunately, when we were all done, the colors faded immediately and it became all white 🙁

    Any idea what I did wrong?
