Swirling ocean waves of color! Make ocean slime for an AWESOME under the sea theme this summer. Use any of our basic slimes including saline solution slime recipe, borax slime recipe, and liquid starch slime recipe to make this ocean theme slime recipe the kids will love to play with! Making slime with our homemade slime recipes is an AMAZING way to connect with kids.
MAKE OCEAN SLIME FOR UNDER THE SEA FUN!
There is so much to love about the ocean. I love the colors especially and that was my inspiration when we decided to make ocean slime for our newest summer slime recipe.
any of our 4 basic homemade slime recipes are quite simple to make for wonderful science and sensory play. I bet you didn’t know slime is science too! You can read more about the science behind the homemade slime recipe below.

HOW TO MAKE OCEAN SLIME
I always recommend reading through our MUST HAVE slime supplies list to see all the brands and items we like to use! The best slime starts with the right ingredients including the right glue and the right slime activator.
Most of our slime themes can be made with any of our basic slime recipes, so don’t feel limited if you can’t use the slime activator we chose to use.
If you need a UK or Canada friendly slime recipe check out our saline solution slime recipe instead.
Plastic Sea or Ocean Animals
GET THE SLIME RECIPE AND INSTRUCTIONS. Click the link directly below. We have three options for slime recipes. Choose the one that best suits you! The photos below show the liquid starch slime recipe.
We used blue and green food coloring and combinations of each to make a variety of ocean colors! Add coordinating glitter to each one for extra sparkle. Silver glitter works just fine too! Always check out the dollar store for affordable ways to stock up on glitter.
Grab sea shells, plastic ocean or sea creatures, and shells to mix into and play with your ocean slime. Kids love to hunt for fun little items in the slime and it’s terrific fine motor practice too.

This slime recipe is on the thicker side but you will see from the pictures that it flows quite nicely! This is a great mini lesson in viscosity and non-newtonian fluids.
We always like to include a bit of homemade slime science around here. Slime really does make for an excellent chemistry demonstration and kids love it too! Mixtures, substances, polymers, cross linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime!
What’s the science behind the slime? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl-acetate) glue and forms this cool stretchy substance. This is called cross linking!
The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until…
When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime!
Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms the tangled molecule strands are much like the clump of spaghetti!
Is slime a liquid or solid? We call it a Non-newtonian fluid because it’s a little bit of both!

HOMEMADE OCEAN SLIME RECIPE
Lay each color out next to each other in long strips to swirl together. The slime will begin to mix quickly!
Once the slime warms in your hands and begins to flow, the colors start to mix together and look just like the amazing colors of the ocean.
This ocean slime is amazing sensory play that even grownups love! Since this recipe is thicker, there is much less mess on the hands during play. Always wash hands after!
We started with three distinct blobs of slime on the table and slowly they spread out and connected with one another. Don’t forget to try out our beach sand slime too. They would be fun to pair together!
The clear glue gives our ocean slime a neat transparency even though it is colored. You can make ocean slime with white glue and food coloring but the results will be different. Still fun though!

STORING YOUR OCEAN SLIME
Slime lasts quite awhile! I get a lot of questions regarding how I store my slime. We use reusable containers in either plastic or glass. Make sure to keep your slime clean and it will last for several weeks. I love the deli style containers in my recommended slime supplies list here.
If you want to send kids home with a bit of slime from a camp, party, or classroom project, I would suggest packages of reusable containers from the dollar store or grocery store or even Amazon. For large groups we have used condiment containers as seen here.
Slime is a cool science material and sensory play activity to explore and this ocean slime is one of the coolest recipe for slime we have made so far this year!
Including discovery bottles, sand slime, crystal seashells, ice melts, and more beach and ocean inspired hands-on learning.
