And his heart grew three sizes that day… Make awesome Grinch slime to go along with the book or movie this season. The Grinch has such a wonderful message for kids and families all year round. Kids will love this fun lime green Christmas slime!
GRINCH SLIME RECIPE FOR A HOMEMADE CHRISTMAS!
The kids will love turning a favorite Christmas book and movie into slime with this super easy Grinch theme activity! Our simple Grinch slime recipe is perfect for little hands. This is just one of our many Christmas slime ideas to try like our Elf Snot Slime!
Slime making is even more fun when you add in creative Christmas themes like the Grinch. We have quite a few to share, and we are always adding more. Our lime green slime is yet another AMAZING slime recipe we can show you how to make.
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 Christmas butter slime. Make a batch in red and green!
- Try adding red foils to a batch of neon green slime (similar to our gold leaf slime).
IS SLIME A LIQUID OR A SOLID?
We always like to include a bit of homemade slime science around here, and that’s perfect for exploring Chemistry with a fun Grinch 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. Read more about slime science here!
GRINCH SLIME RECIPE
If you don’t want to use saline solution as per this recipe, 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!
- 1/2 cup of PVA Clear School Glue per slime batch
- 1/2 tsp baking soda per slime batch
- 1/2 cup water
- Green Food Coloring, Glitter, Confetti Hearts
- 1 tbsp of Saline Solution per slime batch
HOW TO MAKE GRINCH SLIME
STEP 1. Add your glue and water to a bowl and mix well.
STEP 2. Mix in food coloring and red confetti hearts as desired!
SLIME TIP: 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!
STEP 3. Add in your slime activator (baking soda and saline solution) to complete the chemical reaction you read about above. Mix well. You will notice the slime start to thicken and pull away from the edges of the bowl.
If your slime still feels too sticky, you may need a few more drops of saline solution. 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.
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 slime science experiment!
SLIME TIP: 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.
STORING YOUR GRINCH SLIME
Slime lasts quite a while! 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.
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.
