What Makes Slime?
Slime is made when boron mixes with the polymer chains in the glue, creating strong, but flexible bonds between the molecules. There are so many fun tweaks you can make to a basic slime recipe, like my kid’s favorite, fluffy slime!
Since this slime does contain borax, if you have a sensitivity to it, you may want to try our baking soda slime instead.

Tips for Making a Sta Flo Slime Recipe
If this is your first time making slime, you should follow along with our post on slime troubleshooting. Luckily, liquid laundry starch slime made with clear glue is the easiest slime recipe.
If you don’t want to waste a lot of ingredients, try mixing up a small batch first to make sure you won’t have to tweak it before you make the larger version.
We always stock up on gallon sizes of glue and the large laundry starch just in case something goes wrong (but it almost always goes smoothly).

Troubleshooting Your Liquid Starch and Glue Slime
Too runny: You might have put too much water in it. If the slime is too runny, there are two solutions:
- Add more glue. Sometimes this helps soak up the extra liquid.
- Rinse the slime under water. This will release the materials that didn’t bond and you’ll be left with usable slime.
Too sticky: You probably used too much starch. Add a bit more glue and mix.
Weird texture: The slime probably didn’t have enough time to set. Leave it for five minutes, then come back. Stretch and knead the slime for about 2 minutes, then it should return to the proper texture.
Won’t gel: Did you use the right ingredients? We find the best results when using Elmer’s clear school glue and Sta-Flo laundry starch.
Nothing works: Humidity matters when making slime. You may need to adjust the level of water used. The more water, the stickier and more liquid the slime will be.
The less water, the stronger and stiffer the slime will be. If your slime just isn’t right, you might need to adjust the recipe for humidity.

Where can I buy liquid starch?
If you live in the United States, you’ll be able to find it cheapest if you buy it in a local store. I usually find it in the laundry section of a grocery store (but not usually Target or Walmart, for the record).
You can also buy liquid starch for a bit more on Amazon. If you buy the multi-packs it’s cheaper than if you just buy 1.
If you live outside of the United States, I have heard that it’s almost impossible to get Sta-Flo starch there (could be different now, I don’t know). But there are alternatives. Elmer’s now makes a slime activator, which is essentially the same thing as liquid starch.
I wouldn’t suggest getting any other brand of slime activator or glue, they usually fail.
How to Make Slime with Sta Flo
Follow along with this foolproof slime recipe to make perfect sta flo slime every time!
Mix 4 ounces of glue, 3 ounces of water, and food coloring in a container.
Add 4 ounces of liquid starch.
Stir until mixed. At first, all the liquid will be separated, but after stirring vigorously for about 2 minutes, your slime will suddenly come together. It will look a bit stringy and dull at first, but after about two minutes, the slime will fully bond.
After letting the slime sit for two minutes to gel, stretch and knead the slime between your fingers for another two minutes. This will get rid of any residual stickiness and you’ll be able to stretch and pull the slime much farther.
You can even blow bubbles in it!
How to Store Slime
To store slime, put it in an airtight container that is plastic or glass. Don’t store slime in plastic baggies, as it will get too hard to remove from the bag and stick to your hands.
Most slime will last about two days before it gets too sticky to play with. You can try adding more laundry starch to extend its life, but usually, the slime will not be the same after two days.
If you leave slime out to dry, it turns into a plastic-like substance that you can use for fun craft projects!
