Make Sand Slime For Ocean Theme

If you are planning a trip to the beach or looking for ocean activities and lesson plans this year, making slime is always an awesome chemistry activity to include! We also have quite a few other simple and fun ocean activities to check out this summer!

This oozing, stretching, cool sand slime is great for the next time you want something different to do with your class or at home! While you are grabbing sand from the sandbox, why not check out our amazing sandbox volcano experiment too!

How To Make Slime

All of our holiday, seasonal, and everyday slimes use one of five basic slime recipes that are super easy to make! We make slime all the time, and these have become our go-to favorite slime recipes!

I will always let you know which basic slime recipe we used in our photographs, but I will also tell you which of the other basic recipes will work too!  Usually, you can interchange several of the ingredients depending on what you have on hand for slime supplies.

Here we use our Liquid Starch Slime recipe.  Slime with liquid starch is one of our favorite sensory play recipes!  We make it ALL the time because it is so quick and easy to whip up.  Three simple ingredients {one is water} are all you need!

Where do I buy liquid starch?

We pick up our liquid starch in the grocery store! Check the laundry detergent aisle and look for the bottles marked starch. Ours is Linit Starch (brand). You might also see Sta-Flo as a popular option. You can also find it on Amazon, Walmart, Target, and even craft stores.

But what if I don’t have liquid starch available to me?

This is a pretty common question from those who live outside of the United States, and we do have some alternatives to share with you.  Click on the link to see if any of these will work! Our saline solution slime recipe also works well for Australian, Canadian and UK readers.

Now if you don’t want to use liquid starch, you can absolutely test out one of our other basic recipes using saline solution or borax powder. We have tested all these recipes with equal success!

I always thought slime was too difficult to make, but then I tried it! Now we are hooked on it. Grab some liquid starch and PVA glue and get started!

NOTE: We have found that Elmer’s specialty glues tend to be a bit stickier than Elmer’s regular clear or white glue, and so for this type of glue we always prefer our 2 ingredients basic glitter slime recipe.

Sand Slime Recipe

We also have an easy recipe for Kinetic Sand!


  • 1/2 Cup of White PVA School Glue
  • 1/4 Cup of Liquid Starch
  • 1/2 Cup of Water
  • Beach sand, play sand or craft sand
supplies for sand slime


STEP 1:  Measure and add 1/2 cup of clear glue to a bowl.

measure the glue

STEP 2:  Add 1/2 cup of water to the glue and mix well.

measure the water

STEP 3:  Add several tablespoons of your beach or play sand and mix into the glue/water mixture.

add sand to the glue and water

STEP 4:  Measure and add 1/4 cup of liquid starch to your bowl and stir.

Slime will begin to form immediately. You should keep stirring until slime pulls away nicely from sides and bottom of bowl.  You can then begin kneading with your hands until desired consistency is achieved!

Knead your slime for a few minutes to achieve the desired consistency.

How do you use your sand slime? Add shells, a small pail, and a shovel for play! I think it would also be fun to add construction vehicles for a fun play experience.

Storing Your Sand Slime

If you don’t want your sand slime to dry out, store it in a reusable container either plastic or glass. If you keep your slime clean it will last for several weeks. And…if you forget to store your slime in a container, it does actually last a few days uncovered.

 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. For large groups we have used condiment containers as seen here.

The Science Of Sand Slime

We always like to include a bit of homemade slime science around here!  Slime is 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 slime science all about?  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…

You add the borate ions to the mixture,  and it then 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 rubbery like slime! Slime is a polymer.

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!  Read more the science of slime.

Is slime a liquid or solid?

We call it a Non-Newtonian fluid because it’s a little bit of both!  Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density?

Did you know that slime aligns with the Next Generation Science Standards (NGSS)? 

It does and you can use slime making to explore states of matter and its interactions. Find out more below…

  1. For how many kids does this recipe make? Does it make enough for 1 kid or multiple kids?

  2. Just made a batch of this with some sand picked up on a beach trip and it came together really well. My 4 year old is currently playing with the slime and some shells.

  3. That’s awesome to hear! I am glad it worked out well for you. I am wondering about adding dirt lol!

  4. If I were to buy sand for this, would you use builders sand or play sand? I would assume play, but wanted to make sure. Thanks!

  5. I bet you could as long as they are very tiny. Though they may fall out here and there.
