Ever wonder how you can get crystal clear slime? Usually when making slime from clear glue the glue gets quite cloudy with contact solution. But making clear slime is possible with contact solution and we’ll show you how!

Clear Slime Recipe
Crystal clear slime is fun to make! It does take a few extra steps and some waiting involved. But if you follow our method you should have clear slime after 1 to 3 days.
The reason most slime does not turn out clear when using clear glue is that bubbles form when you mix the slime in your hands.
And full disclosure, after you do end up with the clear slime, continuing to play and mix it will cause the slime to go cloudy again. We think it’s fun to watch the transformation though and know your kids will love handling this clear slime (or even make their own clear slime bubbles!) while it lasts.
What is Slime?
Slime is a polymer. Other examples of polymers are Jell-O, gum and rubber bands. White glue is also an example of a polymer. A polymer is made of long chains of polyvinyl acetate molecules. These chains slide easily making the substance like glue easily pourable.
The Science Behind Slime
When you add the contact lens solution to the glue, it counteracts the glue and forms a viscous substance of slime which can be shaped and pulled. This slime forms due to the glue molecules cross-linking with the borate ions. This is a bond that causes the large molecules to no longer slide freely past one another (like the substance was when it was a glue). Therefore resulting in the slime substance!
Will This Slime Recipe Work?
All of our slime recipes are easy to make and should turn out if you follow the instructions carefully. Do not substitute for other brands as your slime may not turn out. The type of contact lens solution we use is very important – this is what turns your glue into slime. We always recommend Elmer’s glue because it’s quality glue and creates the best slime. If you do not have Elmer’s glue in your country you can substitute the glue for another quality PVA glue.
Safety tips: Adults only should make the slime and handle all chemicals. Do not substitute any ingredients in our slime recipes. If you have sensitive skin, wear gloves while playing with the slime. Always wash hands before and after use. If you notice any skin irritation discontinue use immediately. See the bottom of the post for more safety precautions before making your slime.
How Long Does Slime Last?
This slime recipe should last at least 1 week if stored properly. It will typically last much longer. Store in an air tight container or bag. We like to store in a resealable bag so we can press out all of the air from the bag.

Ingredients Needed to Make Clear Slime
– Elmer’s Clear Glue (1/2 cup) Note: We have only tested this with Elmer’s glue and recommend this brand as other brands may not work.
TIP: To save money we like to buy the gallon size of clear glue.
– 1/4 cup of warm water
– 1/2 teaspoon baking soda
– 1 tablespoon of Contact lens solution. **Important: your brand of contact lens solution must contain boric acid and sodium borate. We like this brand the best and use it in all of our slime recipes. See our full contact solution slime recipe for the brands we recommend. Do not substitute for any other brands.
How to Make Clear Slime
1. Get a bowl to mix your slime ingredients in.
2. Mix the baking soda and warm water together until the baking soda is dissolved.
3. Stir the water mixture slowly in with the clear glue and mix until it is combined.
TIP: To prevent the clear glue from making too many air bubbles and looking cloudy stir gently while making your slime.
4. Slowly add the contact solution and mix until it forms slime. Once the slime starts to pull away from the bowl you can take the slime out and knead a little bit with your hands.
5. Put it in a shallow, covered container for 1-3 days until the bubbles disappear. Check that the bubbles are gone before pulling out.
There may be some bubbles at the top that won’t dissolve after a few days. You can take this portion off.
Also, when you pull out of the container you’ll need to be careful not to mix the slime too much. As soon as you start mixing it a lot, bubbles will start to form.

Slime Safety & Precautions
Note: Making slime is a science experiment and safety precautions should still be made when creating slime. By making this slime, you agree to our site terms which you can read here.
- Adults should handle any chemicals and products
- Adults should make the slime
- Always read and follow the labels of products used. If contact lens solution is accidentally ingested, seek medical attention immediately.
- This project is not suitable for children under 4.
- Slime should not be placed in the mouth. Always wash hands before and after playing with the slime.
- If you notice any skin irritation, discontinue use immediately. If you have sensitive skin, wear gloves while making and playing with the slime.
- Slime is a science experiment and should be made and played with in moderation. Do not allow children to make their own slime and do not play with slime for an extended period of time.
