The slime craze continues and so many people are having fun making slime! Not only is slime fun to make – but kids will love stretching and squishing it. You’ve probably heard of all the slime fails. Well you’ve come to the right place for an easy slime recipe. Our favorite slime recipe is made with contact lens solution. It’s the easiest we’ve tried and without borax. So you won’t have to worry about slime fails with this one! Be sure to read the full post and tips below on how to make slime with contact solution!
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. But there are many others you can find as well.
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. If you want to get a similar effect to the photos in this post, you’ll need to buy Elmer’s glitter glue and review our Unicorn slime recipe.
We recommend Elmers as it has been tested and is quality glue. If you do not have Elmers in your country, substitute for the next best quality glue. Do not use dollar store glue as this is what results in a lot of slime fails. The make-up of the glues are not the same. Note, we have only tested this recipe with Elmers.
2. Baking Soda (1/2 TBSP)
4. (Optional) – Add 2 TBSP or up to 1/2 CUP of water if you’d like a stretchier slime.
5. (Optional) – extra glitter

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.
3. Add your 1/2 TBSP of baking soda and mix in thoroughly. Also add 1 TBSP or more of water here (up to 1/2 cup) if you want a stretchier 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 a few teaspoons at a time and then mix. 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. If it’s not the desirable consistency keep kneading. If you find it to still be too sticky, add a bit more contact lens solution.
