AMAZING RECIPE FOR SLIME THAT KIDS LOVE!
BEST SLIME RECIPE FOR UK SLIME LOVERS TOO!
Our slime recipe with saline solution is absolutely versatile for both home and classroom use. It will even work for UK slime recipes and Canadian slime recipes too.
For those of you who need a recipe for making slime that works outside of the US (and in the US too), check out the supplies below and see what you have available. I know that both liquid starch and borax powder are not always available everywhere.
We do have all kinds of AWESOME slime recipes that include the popular fluffy slime, butter slime, floam slime, glow in the dark slime, and more! Click here to see them all.
SALINE SOLUTION V CONTACT SOLUTION
Although both solutions work for making slime, they are not completely the same. They do contain some similar ingredients that are essential for making slime. These slime activators are what react with your PVA glue to form the slimy substance the kids all love! Read more about the science slime of below.
The right slime activator includes the ingredients of boric acid and sodium borate. Hopefully, it includes both but one or the other will work too. Take some time and read through the labels of the bottles in your store.
RECIPE NOTE: If your solution has just boric acid you may need to double the amount. Also, check out eye drops as they contain boric acid too.
CHECK IT OUT: We made a dollar store slime kit using eye drops!
Contact solution and saline solution differ slightly since they don’t serve the exact same purpose. Saline solution is cheaper in general. Contact solution is more expensive and can actually cause your slime to potentially weep over time.
If your saline solution does not list any ingredients, try looking for the term “buffered”. Please note that you can not make your own saline solution.

SLIME RECIPE UK
This is a terrific UK recipe for slime and also works well in Canada too! It makes a stretchy slime that is a bit on the stickier side. However sometimes sticky and stretchy go hand in hand.
We chose a fun summery watermelon theme simply by adding a little pink food coloring and black beads. You can also use black sequins, mini pompoms, buttons, etc…
Did you know that you can also use this recipe for making our favorite fluffy slime? Just add 3 cups of foam shaving cream and remove the water!
- White or Clear Washable PVA Glue
- Saline Solution (or Contact Lens Solution)
- Baking Soda
- Food coloring, glitter, confetti (optional)
STEP BY STEP RECIPE FOR MAKING SLIME
STEP 1: Measure 1/2 cup PVA washable school glue and add to a bowl. Mix with 1/2 cup of water.
STEP 2: Stir in 1/4 tsp of baking soda (You can use 1/2 tsp for thicker slime).
STEP 3: Add food coloring, glitter, or confetti to this mixture and mix to incorporate everything.
STEP 4: Time to add the slime activator (contact or saline solution)! Stir in 1 tablespoon and continue to stir until a blob of slime forms. Note that adding 1/2 tablespoon will make slime even stretchier but stickier initially. We often prefer to use less solution with clear glue.
Your slime should become thick and difficult to stir and should pull away from sides and bottom of the bowl.
STEP 5: Now it’s time to knead. This will greatly help reduce the stickiness. My method is to add a few drops of solution to my hands and knead the slime right into the bowl. Once it feels like it’s ready to be picked up, go ahead and do so. Knead, stretch, and play!

FUN SLIME VARIATIONS
Why not create a honey bee theme for spring and summer fun to go with a learning unit about bees! All you need is a little yellow food coloring and mini bee erasers or plastic bees.
Don’t throw away your fun mix-ins after you are done with the slime! Rinse and re-use for another cool slime theme! Your kids will actually enjoy digging out the fun mix-ins, and then you can give them a bath in soapy water!
HOW DO YOU STORE SLIME?
I get a ton of questions regarding how long does slime last?. Typically slime recipes can last for a few weeks and we have had some last for several months!
That question usually leads to, how do I store my slime? We use reusable containers in either plastic or glass. Make sure to keep your slime clean and it will last for several weeks. If you want to send kids home with a bit of slime from a camp, party, or classroom project, I would suggest packages of reusable containers from the dollar store or grocery store or even Amazon. For large groups, we have used condiment containers as seen here.
We always like to include a bit of homemade slime science around here! Slime is 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 slime science all about? 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…
You add the borate ions to the mixture, and it then 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! Slime is a polymer.
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! Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density?
