Making slime is such a fun activity, once you start you’ll never want to stop!

This easy mermaid slime recipe uses contact solution, baking soda, clear glue, and glitter – that’s only 4 ingredients! It’s perfect for mermaid birthday parties or an ocean theme sensory play!

We specifically wanted to make this slime with contact lens solution (rather than borax powder) to make it safer and more kid-friendly. Plus, the glitter adds an extra sparkle and makes it look like it came straight from the sea!

Our kids played with this mermaid glitter slime for hours, making different shapes and stretching it to see how far they could go! It’s such a great way to encourage creativity and imagination.

Make this homemade slime today, and then check out all of our fun mermaid activities for kids. They’re perfect for kids who love all things mermaid related!

Slime Supplies List

• 1 cup Elmer’s clear glue
• 1 tablespoon baking soda
• 1.5-2 tablespoons contact solution (must contain boric acid)
• Extra fine glitter in shades of blue and green
• Fine purple glitter

How To Make Mermaid Slime

First, encourage your child to pour the cup of glue into a large bowl.

Next, guide your child to add the baking soda and contact lens solution to the bowl – this is the slime activator.

Now, the adult should mix with a fork until combined and the mixture starts to clump together.

Use your hands to knead the slime together until it forms the consistency you like. If it’s too sticky, feel free to add a tiny bit (1 teaspoon at a time) of contact lens solution then knead again.

Once the slime has become the consistency that your child likes, spread it into a small blob, sprinkle the glitter in, and knead it together until all the glitter has mixed into the slime.

For this color combination, we used a teal glitter and a purple holographic glitter.

Sit back and enjoy your fun mermaid slime! You can also store it in an airtight container for future playtime.

If you’re wondering how much glitter to put into this simple mermaid slime, it all depends on how shimmery and reflective you want it. We added 5 different shades of extra fine blue, green, and teal glitter and about 3 teaspoons of fine purple glitter. 

All of the extra fine glitter we’ve used in our fun slime recipes comes from this glitter kit that we bought off Amazon. It’s been really awesome to have so many different choices of glitter right at our fingertips!
