If you follow these directions, you’ll be able to learn how to make slime with liquid starch without any hiccups or mistakes. This simple slime recipe is one of our favorite sensory activities. My preschooler and grade-schooler both love making slime.

Follow along with this foolproof slime recipe to make perfect slime every time!
What you’ll need to make slime with liquid starch:

- Sta-flo liquid starch
- Elmer’s white or clear glue
- Food coloring (we prefer this brand)
- Measuring cup
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 vigeriously 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!
Use this recipe to create tons of slime variations, including:
Troubleshooting Common Problems with 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.
