The Best Mermaid Fluffy Slime Recipe

What You’ll Need

Our Mermaid fluffy slime is a twist on our classic fluffy slime recipe, which is a hit all year long! You’ll need a handful of simple ingredients, many of which you might already have at home:

• 1/2 cup Elmer’s School glue 
• 3 generous cups of foam shaving cream
• 1-2 tablespoons Contact Lens Solution (make sure it contains boric acid or sodium borate): We used Bauch+Lomb Renu.
• 1/2 teaspoon baking soda
• Food coloring for an Easter vibe
• Optional: Glitter to add extra sparkle!
• Mixing bowl and spoon.

Instructions

1. Add the Shaving Cream

Start by adding about 3 generous cups of shaving cream to a large mixing bowl. Go wild with it—this is what makes your slime so fluffy!

2. Add the Glue

Next, pour in your 1/2 cup of white glue. Stir it well with the shaving cream until everything is combined. It’s still going to be light and puffy at this stage, which is exactly what we want.

3. Baking Soda Time

Now, sprinkle in the 1/2 teaspoon of baking soda. This helps firm up the slime and keeps it from being a sticky mess. Stir it into the mixture evenly.

5. Add Mermaid Flair

This is a good time to add a few drops of purple, teal, blue or any other food coloring and stir it in until you get your desired shade. You could also sprinkle in some confetti or glitter for that extra Mermaid sparkle!

5. Add the Activator

Slowly pour in 1 tablespoon of contact solution. Start stirring, and you’ll see the slime start to pull away from the sides of the bowl. It’ll start to look like actual slime instead of a pile of fluff.

5. Knead the Slime

Now for the fun part—time to get your hands in there! Grab the slime and start kneading it. At first, it’ll be sticky, but keep going. The more you knead, the stretchier and less sticky it becomes. If it’s still too sticky after a bit, add a few drops of contact solution until it’s just right.

Pro Tip: Rub a little contact solution on your hands before kneading to help keep it from sticking to your fingers!

6. Swirl It Together

Repeat for each color you want to make. We made blue, teal, and purple. Once each color is ready, gently swirl them together for a gorgeous Mermaid mix! Be careful not to over-mix, or you’ll end up with one solid color instead of a rainbow effect.

How to Store Your Mermaid Fluffy Slime

Once you’ve got your perfect Mermaid Fluffy Slime, you’ll want to store it right so it doesn’t dry out. Pop it into a zip-top bag, glass jar, or any airtight container. It’ll stay fresh for a few weeks if stored properly.

One little note—fluffy slime doesn’t stay fluffy forever. After about a day, the shaving cream will start to lose its puff. Don’t worry though, it’ll still be stretchy and fun to play with!
