How to Make Slime With Contact Solution
There are a number of different slime activators you can use to “transform” your glue mixture into slime. Contact lens solution is our favorite activator. You can also replace this for saline solution, but just make sure that that they contain boric acid and sodium borate.
Why is boric acid important for slime?
Boric acid is made from borax and similarly liquid starch contains sodium tetraborate which is also made from borax. Typically all activators have some derivative of borax. However, we prefer using the contact lens solution as it’s easier to use and more widely available (liquid starch is not available in Canada and Borax is not available in the UK).
This Renu Fresh Contact Lens Solution is one of the recommended brands we suggest since it contains both boric acid and sodium borate.
Ingredients for How to Make Slime With Contact Solution
This easy 3 ingredient recipe is such a popular one! If you haven’t seen our Unicorn Slime made with it, head over to watch the video on how it’s done!
Only 3 ingredients are needed:
1. 1 Bottle of Elmer’s Glue (6 oz) – we like to buy the gallon size and then measure out for savings – you can use 3/4 cup of glue if you have a larger bottle. If you want to get a similar effect to the photos in this post, you’ll need to buy Elmer’s glitter glueand review our Unicorn slime recipe.
We recommend Elmers as it has been tested and is quality glue. Do not substitute any ingredients as your slime may not work.
2. Baking Soda – 1/2 teaspoon
3. 1½ TBSP ofContact Lens Solution – Renu Fresh contains Boric Acid and Sodium Borate. Do not substitute for other brands. Check the label before buying to make sure it has the right ingredients.
4. (Optional) – Add up to 1/4 cup of water if you’d like a more stretchy slime. While water is not needed it really helps the slime become more stretchy so we do recommend adding about 1/4 cup of water to the slime.
5. (Optional) – extra glitter
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.

Steps for How to Make Slime With Contact Solution
1. Get a bowl to mix your slime ingredients in.
2. Pour your entire 6 oz Elmer’s Glitter glue into the bowl (or 3/4 cup of glue from a larger bottle).
3. Add your 1/2 teaspoon of baking soda and mix in thoroughly. Also add up to 1/4 cup of water if you want a more stretchy slime.
5. Slowly add in your contact lens solution (Reminder: your contact lens solution should contain boric acid or your slime will not form).
Add it in slowly and mix if possible so that you can adjust and ensure you do not add too much.
We like to add in 1 tablespoon to start and then mix. Then slowly add in the rest.
Knead and mix thoroughly before adding more as you do not want to add too much or your slime will get too hard.
You may not need the full amount so take this step slowly.
6. Now mix until your slime forms and begins to harden.
Take it out and knead, knead, knead. You may be surprised how much you need to knead to really make the slime form. It will be very sticky at this point. Especially if you added water. Keep kneading and stretching the slime and it will become less sticky.
If it’s not the desirable consistency keep kneading. Only add a little more contact solution a teaspoon at a time to prevent the slime from becoming too hard.
If you still find it to still be too sticky, add a little bit of lotion or baby oil to your hands.
