If you’re a regular reader of Fun-A-Day, you know we’re big slime fans around here.
I know that not every adult (or kid!) enjoys making slime. And that’s perfectly okay! But I happen to really have fun with it. In fact, I’ve had friends tell their kids, “No slime in the house. Call Miss Mary Catherine and see if you can make slime with her!”
Honestly, I think I like it so much because the kids do. Their excited faces, their astute observations, and all of the giggles make the process a blast.
Liquid Starch Slime
Let’s get started learning to make slime with liquid starch. I have to admit, it’s my absolute favorite way to make slime.
I’ve tested out a variety of methods, but I keep coming back to this one in particular.
Starch Slime Ingredients
You really don’t need many materials for the basic Sta-Flo slime recipe. Here’s what you need to get started (I may get commissions for purchases made through links in this post):
- Glue
- Liquid starch
- Water (optional)
Yes, that’s really it! Of course, once you have the basic slime recipe, there are endless possibilities regarding what you add. Here are some suggestions:
How to Make Slime with Liquid Starch
Now it’s time to get down to the nitty-gritty of how to make slime with liquid starch.
Here’s the basic liquid starch slime recipe I like to use:
- 4 ounces of glue
- 3 ounces of warm water (optional)
- 3 ounces of liquid starch
Start off by adding your glue to a bowl. You can use any type of glue for this – clear, white, or even glitter glue!

I have a set of bowls that we use just for science and sensory fun. If you make slime as often as we do, I suggest you do the same!
Next, add the warm water to the glue and mix it well. This is an optional step. Sometimes I use the water, but sometimes I don’t.
If you’re going to color your slime, now’s the time to add food coloring or liquid watercolors. Add in any glitter you want to use now, too.

Finally, slowly mix in the liquid starch. I prefer to use the Sta-Flo brand, as it’s easiest for me to get my hands on.
Then take a few minutes to knead your starch slime. This will help get the slime to the right consistency. I, myself, like slime that is stretchy but not sticky.

You can add other items, like gems or beads, at this point. Then let the kids stretch and play!
Liquid Starch Slime Ideas
Now you know the basics for making your own slime with liquid starch! As I mentioned earlier, the possibilities are really endless.
You can create slimes based on preschool themes, your students’ interests, the seasons, the weather, or basically anything else you can think of!
Just in case you need some ideas to kick start your slime creations, here you go:

Slime Safety
I always want to touch on safety when talking about slime. Slime is a science experiment and should always be treated as such.
None of the ingredients, or the end product, should ever be ingested. If you have children who still put things in their mouths, try placing slime inside of sturdy plastic baggies or in sensory bottles.
Make sure the kids wash their hands before and after interacting with the liquid starch slime. Keep an eye out for skin reactions. While I’ve never seen any happen, it’s still something to be aware of.
Science is super fun, especially when done safely!
