If you’ve ever wondered how to make slime, you’re in luck. Today I’m sharing a super simple slime recipe that can be modified to fit any theme. We used this recipe to create our ocean slime!

We have been on focusing on all kinds of ocean themed activities for kids. Be sure to check out some of our favorites:

Ocean Slime Recipe

This was my children’s first experience with homemade slime, and I have to say I wish I had tried it sooner. Theo and Lucy went absolutely nuts playing with it, and it was so easy to make. Below is the recipe for making your own slime. Feel free to substitute colors to make it fit your own theme!

(DO NOT allow children that still put things in their mouth to play with this particular slime recipe or ever leave any child unattended while playing. This recipe uses ingredients that are not safe when ingested. At the end of the post I will leave some links for some taste-safe slime recipes for the younger ones to enjoy!)

Ingredients for Ocean Slime

1/2 cup water
1/2 cup liquid glue (We used white glue, but you can also use clear for a slightly different look.)
1/2 cup liquid starch
Liquid watercolors
Glitter (optional)

Directions for Making Ocean Slime

1. Start by pouring the water and liquid glue into a bowl. Mix until combined.

2. Add your liquid watercolor to the glue-water mixture. (We actually made a few batches and colored one regular blue and one turquoise.)

3. Add glitter. (If you are not a fan of glitter, I’d skip this step because you will have some glitter around after playing with the finished slime.) We added some silver, blue and green glitter to ours.

4. Add the liquid starch and stir.

5. Once the mixture begins to thicken and climb up your spoon, you can knead it well by hand.

6. Check the consistency. It should be nice and stretchy, but not stringy or super sticky. (If your ocean slime didn’t turn out quite how you were hoping, it’s an easy fix! Just go here to read How to Fix Slime that Didn’t Work Out for details.)

7. You can store your ocean slime in an airtight container for up to two weeks!

Playing with Ocean Slime

Be sure to find a place to play with slime that you don’t mind getting a bit messy. We played in our kitchen at the table since the table and wood floors are easy to clean. Also, my son did get some slime on his shirt which washed off in the washer, but just in case, be sure your kids are wearing play clothes.

The kids started off by just exploring the slime. They’d stretch it and see how long they could make it get.

Theo tried to make his as long as Lucy’s.

Theo just couldn’t get enough of the stretching. Here’s the best picture I could get of him playing- he was just always in action!

Lucy decided to mix our turquoise and blue slime together. She loved watching how the colors mixed…

…and just squishing it over and over!

We added some of our ocean animals to the slime. Their favorite part was making impressions in the slime with the ocean animals and then watching the impressions slowly disappear.
