Monster slime recipe using saline solution slime recipe


We always like to include a bit of homemade slime science around here, and that’s perfect for exploring Chemistry with a fun fall theme. 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 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 form 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 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! 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!

SLIME FOR NGSS: Did you know that slime aligns with the Next Generation Science Standards? It does and you can use slime making to explore states of matter and its interactions. Check out NGSS 2-PS1-1 for more information!

Is slime a liquid or solid? We call it a Non-newtonian fluid because it’s a little bit of both!

The base for this google eye monster slime uses one of our most basic slime recipes (saline solution slime recipe) which is clear glue, water, baking soda, and saline solution.

Now if you don’t want to use a saline solution, you can absolutely test out one of our other basic recipes using liquid starch or borax powder.

As I mentioned above, you can use any of our basic slime recipes for this Halloween theme slime, but we like our basic saline solution slime recipe with the Elmers white washable school glue.

1/2 cup of Elmer’s Clear Glue

1/2 cup of water

1/2 tsp baking soda

Food Coloring and Google Eyes

1 tbsp of saline solution (see recommended slime supplies for brands)

See the written instructions below the photos!

The best slime recipe starts with the right slime ingredients. Make sure to follow along with our measurements. Start by adding your clear glue and water to a bowl and grab a mixing utensil. Mix it up and add food coloring and glitter as desired! Save adding the google eyes till a bit later in the recipe. See below.

Don’t be shy with the glitter. Check your local dollar store to stock up too!


Add in your slime activator (baking soda and saline solution)  to complete the chemical reaction you read about above in the science behind the slime section. If you scrolled past it, go back and read it with your kids!

You can also learn more about all our favorite slime activators here. Keep in mind that liquid starch, saline solution, and borax powder are all in the boron family. Neither of these ingredients is truly borax free.

Go ahead and add the google eyes now! It’s easier to mix in the baking soda well of it isn’t clinging to eyeballs!

We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve its consistency. The trick with saline solution slime is to squirt a few drops of solution onto your hands before picking up the slime.

You can knead the slime in the bowl before you pick it up as well. This slime is ultra stretchy but can be stickier. However, keep in mind that although adding more solution reduces the stickiness, it will create a stiffer slime.

Our slime recipes are so easy to change up with different themes for holidays, seasons, favorite characters, or special occasions. Saline solution is always super stretchy and makes for great sensory play and science with the kids!



STEP 1: Add 1/2 cup of Elmers Glue to your bowl (add more glitter if desired).

STEP 2: Mix with a 1/2 cup of water.

STEP 3: Add food coloring and glitter.

STEP 4: Stir in 1/2 tsp baking soda

STEP 5: Add a handful of google eyes as desired.

STEP 6: Mix in 1 tbsp saline solution and stir until slime forms and pulls away from sides of the bowl. This is exactly how much you will need with the Target Sensitive Eyes brand!

If your slime still feels too sticky, you may need a few more drops of saline solution. As I mentioned above, start by squirting a few drops of the solution onto your hands and kneading your slime longer. You can always add but you can’t take away. Saline solution is preferred over contact solution.

NOTE: We have found that the Elmers Glitter Glue tends to be a bit stickier than their regular clear glue and we prefer our 2 ingredient slime recipe for this glue.

Halloween party favors can be so much more than candy. Even better it means that all kids regardless of allergies can enjoy the fun and excitement of Halloween. If you are throwing a Halloween party or even a Halloween play date, make slime with the kids. They will have a blast and so will you!


How about Randall from Monsters Inc or the purple people eater!

Here’s our blue slime. Kind of reminds me of Sully from Monster’s Inc.

Sully from Monsters Inc makes a great theme for this monster slime recipe

This one looks good for Mike from Monsters Inc or to go along with a Ghostbuster movie marathon.

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 size containers as seen here.
