Which Slime Recipe To Use?
We have several basic slime recipes that can all be used for this chalkboard slime recipe. You decide which one works best for you depending on what slime activator you want to use. This allows for some flexibility depending on where you live in the world! Not everyone has access to the same ingredients!
Each of the basic slime recipes below have the full step by step photos, directions, and even videos to help you along the way!
In the recipe below, we used our Liquid starch slime recipe. Only 3 ingredients, liquid starch, water and glue, and you have slime in no time is my motto!
Easy Chalkboard Slime Recipe
Ingredients:
- 1/2 cup of White Washable PVA School Glue
- 1/2 cup of water
- 1/4-1/2 cup of Liquid Starch
- Chalkboard Paint
- Chalk Markers
Instructions:
TIP: If you want to make a larger amount of slime you can easily double or triple the recipe.
STEP 1: Add 1/2 cup of 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. (Add the whole bottle if you are tripling the recipe!)
STEP 4: Slowly mix in 1/4 cup of liquid starch and stir until slime forms.
TIP: 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.

The Science of Slime
We always like to include a bit of homemade slime science around here. 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!
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!
