Oh and slime is science too, so don’t miss the great information on science behind the slime. Art meets slime for some cool STEAM play too. Want to see how slime fits into your classroom, click here?
SLIME SCIENCE, CHEMISTRY FOR KIDS, AND ART!
We always like to include a bit of homemade slime science around here, and that’s perfect for STEAM which is science, technology, engineering, art, and math. We have a brand new series out on NGSS science standards, so you can read how this will fit in nicely too!
Slime really does make for 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…
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!

CHALKBOARD SLIME INGREDIENTS
As I mentioned above, you can use any of our basic slime recipes for this chalkboard slime, but we like this super quick liquid starch slime recipe with the Elmers basic white school glue. I will link the products we used here with Amazon affiliate links.
NOTE: Our slime maker made a huge triple batch of this slime. You can make a single batch for fun results too! If you would like to watch us make liquid starch slime start to finish, click here.
1/2 cup of Elmer’s Washable Glitter Glue
1/2 cup of water
1/4-1/2 cup of Liquid Starch such as Sta Flo Brand
HOW TO MAKE CHALKBOARD SLIME RECIPE DIRECTIONS BELOW PHOTOS
The best slime recipe starts with the right slime ingredients. Make sure to follow along with our measurements. Start by adding your white glue to a bowl and grab a mixing utensil. If you want to make a larger amount of slime you can easily double or triple the recipe. Mix in the water. It’s a 1:1 ratio of water and glue.
Mix to combine the water and glue thoroughly.
Add in about 1/3rd of the bottle of chalkboard paint or the whole bottle if you are making a triple recipe!
BEST SLIME ACTIVATORS
Add in your slime activator 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 are truly borax free.
Add the activator slowly. For a single batch of slime 1/4 cup does the trick, but if you think it’s still too sticky, continue to add a few drops at a time until you find the consistency you want.
The first time you make slime usually needs some experimentation to find the slimy consistency that’s right for you. Slime making can be a bit like goldilocks finding the right bed or the right porridge. Some kids like it messier and some kids like it firmer.
Now it’s time to play with your slime!
Stretch your homemade slime. Kneading and playing with your slime after the mixing process helps to improve the consistency.
Squish your homemade slime! Always an AWEOSME tactile sensory experience.
3 INGREDIENT SLIME RECIPE WITH LIQUID STARCH AND GLUE
Single Batch Recipe.
STEP 1: Add 1/2 cup of Elmers White Washable School Glue to your bowl.
STEP 2: Mix in 1/2 cup of water.
STEP 3: Add 1/3rd of a bottle of chalkboard paint and stir to combine.
STEP 4: Slowly mix in 1/4 cup of liquid starch and stir until slime forms.
If your chalkboard slime still feels too sticky, you need more liquid starch. Be careful, and add just a little at a time until you get the consistency you want. If you add too much liquid starch your slime will become stiff and rubbery. You can always add but you can’t take away.
Now it’s time to grab your chalk markers and have some fun! Go ahead and let your slime spread out on a smooth, flat, and clean surface!
You can make patterns, draw pictures, or write I LOVE SLIME! You can get so creative with this homemade chalkboard slime recipe.
Have fun exploring the slime and chalk art as it combines! Kids benefit greatly from mixing art and science because it combines thinking from the left and right brains or the more analytical side and the more creative side! Learn how to make chalkboard slime for hands on learning mixed with play.
Go ahead and lift and stretch the slime to watch the patterns stretch out too.
Learn how to make chalkboard slime for a cool party idea. Perfect slime making activity for teens and tweens too.

STORING YOUR 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.
