Don’t have the usual slime activators like borax powder or liquid starch to make slime? Make awesome stretchy slime with saline contact lens solution as an alternative. Read on for the full slime recipe using contact solution. Making homemade slime is a must do with the kids!
The Most Important Thing!!
Check the ingredients of your contact solution first and make sure that it contains a mix of sodium borate and boric acid.
This is the slime activator and without it your slime with not come together, and it will end up a sticky mess! No one will want to play with that! See our slime activator list for more info!
Contact Solution Slime Recipe
This slime recipe is so cool to make and it uses supplies you may already have on hand! Making slime with clear glue is perfect for this gorgeous glitter effect. White glue just doesn’t work. Plus you can see the intense color of the slime. Check out our liquid glass clear glue slime recipe too!
Ingredients:
- 1/2 cup Clear PVA School Glue
- 1 tablespoon Contact Solution (must contain boric acid and sodium borate)
- 1/2 cup of Water
- 1/2 tsp Baking Soda
- Food coloring, confetti, glitter, and other fun mix-ins
Instructions:
STEP 1: To a bowl add 1/2 cup of glue and mix with 1/2 cup of water.
STEP 2: Add coloring and glitter! The more glitter the better. Start with one drop of color. It goes a long way! Mix
STEP3: Add 1/2 TSP of baking soda {helps firm the slime} and mix.
STEP 4: Add 1 TBL of solution. Again make sure that your solution contains boric acid and sodium borate. These are the slime activators.
STEP 5: Really whip it up to mix and you will feel the slime come together!
STEP 6: Once you have mixed it up well, you want to knead it well! Squirt a couple drops of solution onto your hands and pull the slime out of the bowl. You will notice that it is sticky at first but the more you knead it the less sticky it gets.
STEP 7: Time to play and learn! Slime is science too!
You can store your slime in a reusable container. We have actually been using glass containers lately but you can use plastic too. Wash hands and surfaces thoroughly after making and playing with slime.
There you have it! Really cool, homemade slime the kids will love. What are you waiting for, grab the ingredients you need and get started. Homemade slime is a must try activity with kids of all ages, and we even have borax free slime recipes for the youngest slime lover too!
UPDATE: We are finding that using contact solution sometimes results in a more watery slime when you want to play with it the next day. However, saline solution will not. This is our favorite go-to saline solution slime and saline solution fluffy slime recipes!
The Science of Slime
We always like to include a bit of homemade slime science around here. Slime really does make for an excellent chemistry demonstration and kids love it too! Mixtures, substances, polymers, cross linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime!
What’s the science behind the slime? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl-acetate) glue and forms this cool stretchy substance. This is called cross linking!
The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until…
When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime!
Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms the tangled molecule strands are much like the clump of spaghetti!
Is slime a liquid or solid? We call it a non-Newtonian fluid because it’s a little bit of both!

Pingback: Make Christmas Slime Recipe Easily With Tinsel Glitter for Kids
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!
