Making homemade slime recipes is a breeze with our easy to make slime ideas, instructions, and videos. This fluffy slime recipe has an extra special ingredient, but you don’t need to include it!

Watch this videos of this slime recipe being made, and then get ready to try it for yourself. We have tons of handy resource guides for making the best slime ever. You can even read about the science behind the slime below.


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!

Here we use our Saline Solution Slime recipe.  Slime with saline solution is one of our favorite sensory play recipes!  We make it ALL the time because it is so quick and easy to whip up.   Four simple ingredients {one is water} are all you need.  Add color, glitter, sequins, and then you are done!

Where do I buy saline solution?

We pick up our saline solution in the grocery store! You can also find it on Amazon, Walmart, Target, and even at your pharmacy.

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

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 ingredient basic glitter slime recipe.


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!

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…

Easy Fluffy Slime Recipe for Kids


This fluffy slime showcases an extra special ingredient, colored craft sand! Although it gives it a fun texture, it’s not at all necessary to making fluffy slime!

Make sure to wash hands thoroughly after playing with slime.  If your slime gets a little messy, it does happen, check out my easy tips for how to get slime out of clothes and hair!


  • 1/2 cup Clear or White PVA School Glue
  • 1 tablespoon Saline Solution (must contain boric acid and sodium borate)
  • 1/4-1/2 tsp Baking Soda
  • 3 cups shaving foam
  • Food coloring
  • 1/2 cup colored craft sand (optional)

STEP 1: Add 3 heaped cups of shaving cream to a bowl.

STEP 2: Choose your favorite color and add a few drops to the shaving cream. Stir it all together but slowly! You want to keep the fluff in the shaving cream.

OPTIONAL STEP: Add your colored sand. The craft sand makes for a cool texture but totally not necessary!

STEP 3: Add the glue. White washable PVA school glue works best for fluffy slime. We buy it by the gallon so its much cheaper that way.

STEP 4: Add the baking soda. This helps the firmness of the slime.

STEP 5: Now it’s time to add the slime activator! We use saline solution, but it must contain sodium borate and boric acid.

You can read more about slime activators and why these ingredients here.

STEP 6: Give it a good stir! It’s going to get thick and tough to stir. Time to get your hands in there. You can take it out to knead or start kneading right in the bowl.

Coat your hands with a bit of saline solution and knead your slime until a smooth, desired consistency is achieved.
