GRINCH SLIME SCIENCE AND CHEMISTRY

We always like to include a bit of homemade slime science around here, and that’s perfect for exploring Chemistry with a fun Candy Cane 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 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…

SLIME IS A NON- NEWTONIAN FLUID

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!

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?

EASY GRINCH SLIME IDEAS

We made this Grinch slime with clear glue, food coloring, glitter and confetti hearts. However, white glue is super easy to use and also works well for this recipe, but your color will be slightly different!

Come up with your own favorite Grinch theme slimes:

  • Try adding a cup of foam beads to the recipe for a floam slime. Make a batch in green and a batch in red. Use heart shape cookie cutters to make floam hearts.
  • Try kneading in an ounce or two of soft clay after your slime is made for a butter slime (see it here). Make a batch in red and green!
  • Try adding red foils to a batch of neon green slime (see it here)!

GRINCH THEME SLIME TIPS 

The base for this Grinch slime uses one of our most basic slime recipes which is clear glue, water, baking soda, and saline solution.

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 three recipes with equal success!

Our easy, “how to make” slime recipes will show you how to master slime in 5 minutes! We have spent years tinkering with our 4 now 5 favorite basic slime recipes to make sure you can make the BEST slime every time!

GRINCH SLIME RECIPE DIRECTIONS BELOW 

This fun Grinch movie or book slime activity calls for one batch of our easy Christmas slime recipe. You can make more or less depending on your character ideas! In general, several kids can share one batch of this butter slime, but it will be harder to twist candy canes.

The best slime recipe starts with the right slime ingredients. Make sure to follow along with our measurements. Start by adding your glue and water to a bowl and grab a mixing utensil. Mix it up and add food coloring and glitter as desired!

EASY GRINCH GREEN SLIME

Combine water, glue, and food coloring in a large bowl and mix well! Next add baking soda. You can also go ahead and add glitter and your red confetti hearts. make sure to save some for Valentine’s Day slime too!

SLIME TIP #1: For a Grinchy-green slime color, you can use the neon green food coloring. Or try a couple drops of yellow with a drop of green. Make sure to not make the slime too dark in color so you can really see your hearts!

BEST SLIME ACTIVATORS

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!

What does the baking soda do? It adds the firmness the mixture needs so you can pick it up. This ingredient is a great variable to tinker with for a science experiment!

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 are truly borax free.

We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve it’s 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 stretchy but can be stickier. However, keep in mind that although adding more saline solution reduces the stickiness, and it will eventually create a stiffer slime.

SALINE SOLUTION SLIME RECIPE FOR MAKING CHRISTMAS SLIME IDEAS

STEP 1: Add 1/2 cup of clear Elmers Glue to your bowl

STEP 2: Mix with a 1/2 cup of water

STEP 3: Add food coloring, glitter, and red confetti hearts as desired

STEP 4: Stir in 1/4- 1/2 tsp baking soda

STEP 5: Mix in 1 tbsp saline solution and stir until slime forms and pulls away from sides of bowl. This is exactly how much you will need with the Target Sensitive Eyes brand, but other brands may differ slightly!

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 specialty glues tend to be a bit stickier than their regular glue, and we prefer our 2 ingredient slime recipe for this glue. Check out our Elf Snot Slime made with this recipe.

STORING YOUR GRINCH 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.
