Want to make slime without borax powder or liquid starch? This contact solution slime recipe is the perfect alternative for homemade slime. Using simple ingredients like school glue, baking soda, and contact lens solution, you can create stretchy, squishy slime that’s a hit with kids of all ages.

🧪 Quick How-To
To make slime with contact solution, combine 1/2 cup of clear school glue, 1/2 cup of warm water, 1/2 teaspoon of baking soda, and 1 tablespoon of contact solution (with boric acid and sodium borate). Stir until the slime forms, then knead until stretchy. Add food coloring or glitter for extra fun!
💡 Please note this is not a borax-free slime recipe! Alternatively, you can use saline solution to make slime. Saline solution and contact solution are not the same.
Why Make Slime with Contact Solution?
If you don’t have borax powder or liquid starch, you can still make a great batch of slime. The secret is using contact lens solution that contains both boric acid and sodium borate—two key chemicals that act as slime activators.
This is a fun and easy chemistry activity for kids and allows for lots of creative mix-ins like glitter, confetti, and food coloring. It’s also one of the easiest borax-free slime recipes to customize.
Slime Recipe Ingredients
To make one batch of slime, you’ll need the following ingredients:
- 1/2 cup clear PVA school glue (like Elmer’s)
- 1/2 cup warm water
- 1/2 teaspoon of baking soda
- 1-2 tablespoons of contact solution (with boric acid and sodium borate)
- Food coloring, glitter, or confetti (optional)
Supplies Needed
- Mixing bowl
- Measuring spoons and cups
- Mixing spoon or spatula
- Airtight container for storage
How to Make Contact Solution Slime
Step 1: Pour 1/2 cup of clear glue into a mixing bowl. Add 1/2 cup of warm water and stir to combine.
Step 2: Add a few drops of food coloring and a generous amount of glitter or confetti. Stir well to get an even slime color.
Step 3: Mix in 1/2 teaspoon of baking soda. This helps firm the slime and gives it a better consistency.
Step 4: Add 1 tablespoon of contact lens solution. Stir quickly! The slime will start to pull away from the sides of the bowl.
Step 5: Rub a small amount of contact solution on your hands. Take the slime out of the bowl and knead it. The texture will be sticky at first, but keep kneading until the slime becomes stretchy and smooth.
Slime Troubleshooting Tips
💡Read on how to fix slime recipes here. Read on if you need to get slime out of hair or clothes.
- Sticky Slime? Add a few drops of contact solution and knead again.
- Rubbery Slime? You may have used too much activator. Next time, reduce the contact solution.
- Too Watery Later? Some brands of contact solution break down faster. Try a saline solution slime instead for better storage.
Slime Safety Tips
- Supervise young kids when making slime.
- Avoid contact with eyes or mouth.
- If your child has sensitive skin, use gloves to avoid skin irritation.
- Rinse hands and surfaces after play.
- Seek medical attention if any unusual reaction occurs from the slime or chemicals.
The Science Behind Slime
This slime is a great hands-on chemistry activity. It demonstrates how a chemical reaction can turn a liquid into a solid-like substance.
The glue contains polyvinyl alcohol (PVA), a polymer made of long chains of molecules. When mixed with borate ions from the contact solution (boric acid and sodium borate), a reaction called cross-linking happens. This causes the long strands of glue molecules to tangle and thicken into slime!
This forms a non-Newtonian fluid, which behaves like both a liquid and a solid depending on how you play with it.

Make It a Science Project
Want to take slime-making a step further? Create a science fair experiment by comparing different slime activators: borax powder, saline solution, liquid starch, and contact solution. Measure stretchiness, texture, and how long each batch of slime lasts.
Encourage kids to form a hypothesis, test each slime recipe, and record their observations! You’ll find project pages in our Slime Science Pack!

FAQs About Contact Solution Slime
Can I make slime with just glue and contact solution?
No. You also need baking soda to help activate the slime and firm it up.
What if my contact solution doesn’t work?
Check the label! It must contain boric acid and sodium borate. Without those, the chemical reaction won’t happen.
Is this slime safe for all ages?
Yes, with supervision. Young kids or those with sensitive skin should wear gloves, and all kids should wash hands after play.
Can I use white glue instead of clear glue?
Yes, but the slime won’t look as vibrant. Clear glue works best if you’re using glitter, confetti, or want intense slime color.
What’s the best way to store slime?
In an airtight container. Glass jars or resealable plastic containers work great. This helps your batch of slime last longer.

HELP!! We made a slime using elmers pink glitter glue, baking soda, water, & contact solution, however it seems i have over activated it or something! It’s not as soft as it should be, & it doesn’t stretch very well, before ripping/breaking. What can I do to fix this?! Please help save our slime! Thank you!
Sadly, we do not like the pre packaged glitter glue for slime. There’s not a great fix other then starting over with clear glue and food coloring and glitter instead. Make sure to use saline solution instead!
