Inside: How to make liquid starch slime with only 2 ingredients. Find out why liquid starch slime is the easiest slime recipe to make!
The Easiest Slime Recipe
Two ingredients — it really doesn’t get any easier than that!
Over the past couple years, I’ve been dubbed a “slime blogger,” a nickname I wear proudly!
We’ve tried LOTS of different slime recipes — from fluffy slime, to glow-in-the-dark slime, to edible slime. I have to say that it is hard to pick a favorite because I love them all for different reasons!
However, if you asked me to pick the easiest slime recipe to make, hands-down it is liquid starch slime.
Why We Love Liquid Starch Slime
- You only need two base ingredients
- It is easy to customize by adding food coloring, glitter, etc.
- All you need to do is mix and stir!
- It’s stretchy, squishy, poke-able…perfect slime!
- Liquid starch slime can be the base for fluffy slime, floam, and more!

What is Liquid Starch and Where to Find It
For your convenience in re-creating our slime recipes, I’ve included shop-able ad links to some of the products we used. Our disclosure policy is available here.
Liquid starch is a laundry product used to keep natural fibers stiff — imagine a crisp button-up shirt and you’ll get the idea.
Because it contains a special ingredient (sodium borate or sodium tetraborate), liquid starch also make a perfect slime activator!
How Slime Activators Work
When making glue slime, you need a slime activator that contains an ingredient from the borate family. This could be borax powder, contact lens solution, or liquid starch (like in this recipe).
When you mix PVA glue (like Elmer’s white school glue) with your slime activator, a chemical bond forms. The borate ions in your activator form a link between the polymers in the glue. Instead of flowing freely like a liquid, this new slime solution becomes a stretchy semi-solid substance, also known as a non-Newtonian fluid.
I love how fellow blogger Sarah at Little Bins for Little Hands explains it:
Instead of flowing freely, the molecules become tangled and create the slimy substance. Think wet, freshly cooked spaghetti versus leftover cooked spaghetti!
When used for laundry purposes, concentrated liquid starch is diluted with water and sprayed onto clothes to achieve the desired effect. However, for our slime-making purposes, we’ll use the concentrated liquid starch.
In the United States, you can find liquid starch, like Sta-Flo (which is what we used) in most grocery stores or even craft stores. It is also available online on sites like Amazon.
TIP: If you live outside the United States and have trouble finding liquid starch, try our contact lens solution slime instead.
Slime Safety Tips
Before we get started, I always like to make sure we go over a few important details.
Slime is lots of fun and a wonderful sensory experience for kids! However, it’s important to make sure to follow all slime safety recommendations:
- This slime is not edible. Please do not taste or eat.
- Always supervise children when making and playing with any slime recipe.
- As with many slime recipes, this liquid starch slime involves a chemical reaction. Some ingredients may cause irritation to sensitive skin. Always wash hands thoroughly after play.

Liquid Starch Slime Ingredients
TIP: We stick with name brands like Elmer’s Glue because generic formulas don’t seem to work as well.

Liquid Starch Slime Recipe
Pour glue into a mixing bowl.
TIP: If you’d like to customize your slime with food coloring and/or glitter, mix it into the glue before you add your activator.
Add 1/4 cup liquid starch and stir with a spoon or wooden craft stick until a cohesive ball of slime starts to form.
Finish kneading slime by hand.
TIP: It could take 2-3 minutes of working the slime to get just the right consistency. You’ve got to make sure that all of the glue and liquid starch mixes together so all of the solution has time for the chemical reaction to occur.
If after a few minutes your slime still sticks to hands, try adding more liquid starch (1 Tablespoon at a time), until slime is no longer excessively sticky.
How to Store Your Liquid Starch Slime
- After you’ve finished playing with your liquid starch slime for the day, keep in a sealed air-tight container. You could use a rubbermaid container or even a ziplock bag.
- To prolong the life of your slime, always wash hands before playing to minimize contamination.
