We love slime recipes, and we love mermaids. That is how the idea for this fun mermaid slime was born. For this recipe, we used a slightly modified version of our regular liquid laundry starch slime to make a thicker texture that was easier to use with toys. The slightly thicker slime looked and felt just like what we imagined a mermaid’s tail would look and feel like. The glitter flakes become the “scales” of the mermaid and it was so much fun playing with this slime! My kids had fun not only playing with the basic slime, but we also used mermaid erasers to play in it and my daughters decided to transform the slime into a real mermaid tail for their barbies.

THE ULTIMATE MERMAID SLIME RECIPE
THE SCIENCE OF MERMAID SLIME
Slime is made when boron mixes with the polymer chains in the glue, creating strong, but flexible bonds between the molecules. There are so many fun tweaks you can make to a basic slime recipe, like my kid’s favorite, fluffy slime! Since this slime does contain borax, if you have a sensitivity to it, you may want to try our baking soda slime instead.
TIPS FOR MAKING YOUR MERMAID SLIME RECIPE A SUCCESS
If you don’t want to waste a lot of ingredients, try mixing up a small batch first to make sure you won’t have to tweak it before you make the larger version. We always stock up on gallon sizes of glue and the large laundry starch just in case something goes wrong (but it almost always goes smoothly).

“Under the Sea” Mermaid Slime For Mermaid-Loving Kids
Kids will love this slightly thicker version of slime that is ideal for using with toys and is almost completely mess-free (as long as you keep it away from fabric).
What you’ll need to make mermaid slime:
- Liquid laundry starch
- Pink glitter
- Blue glitter
- White glitter
- Elmer’s clear glue
- Mermaid mini-erasers (ours came from Target, but these are similar)
Mix a bottle of clear glue (which is about five ounces) with slightly less than half a cup of water. This is what gives the slime a bit more structure, leaving it more “fish-like.”
Dump in quite a bit of blue, pink, and white glitter and mix. The three colors of glitter will mix together and reflect off one another, creating a sort of incandescent purple color that looks quite similar to a fish’s scales. The texture of the glitter also adds to the effect.
Add 1/2 a cup of liquid laundry starch to the mixture and stir. Like all laundry starch slime, it takes a little while for the ingredients to completely mix. At first, it will be super sticky, but after about five minutes, it will be smooth to the touch and won’t stick to anything at all.
My kids love stretching and playing with slime, but they are also in a mermaid eraser phase. My kids used their slime with our mini mermaid erasers.
Then, they had the idea to give their barbies real mermaid tails with the slime. This would never have worked with regular slime, but because this version is thicker, the slime became the perfect mermaid tail for Barbie.
So many fun ways to play with this mermaid slime!
