Super Easy Slime Recipes

By  | 

Updated slime tip……. I’ve found THE easiest slime to make of ALL the slimes!!!!

1 stick of Blu Tack + 2/3 pumps of hand soap = STRETCHY SLIME!!

No borax, no measuring, no mess, no fail slime!

But if you’re after the messy gooey super fun to make slime….keep reading.

My 5 year old is SLIME OBSESSED at the moment! Not a weekend goes by where I haven’t tried, or at least been asked (4 thousand times) to make slime. We’ve YouTube-d and tried all sorts of combinations of toothpaste, shaving cream, borax, flour, dishwashing liquid, white glue, clear glue and ENDLESS tubes of glitter. Some of them KINDA worked…….most of them DID NOT work.

But today……. we had a slime breakthrough and it was actually pretty easy in the end. The below recipe is for quite a gooey slime so experiment with your borax/water quantities for a different result. Now go forth and slime!

**UPDATE** Since I posted this we’ve really upped our slime game and started making Fluffy Slime. Just as easy just needs a few extra ingredients. CLICK HERE for our Fluffy Slime Recipe.

What you’ll need

  • Borax (found in the cleaning aisle of the supermarket and about 5 bucks)
  • Craft Glue. We used white craft PVA glue from Kmart. $4 but you can apparently also use clear glue or glitter glue which we’ll try next time. Oh and grab two lots so you can have at least a couple of tries.
  • Water
  • 2 bowls
  • Glitter, food colouring, sparkles, confetti whatever you want to add to make your slime special. We needed LOTS of glitter to make it work so get a big tub.
  • Air tight containers to store

And a good tip to remember……vinegar dissolves slime.

How to make it

  1. Mix 1 teaspoon of borax in a bowl with 1 cup of warm water
  2. In the other bowl add 1/2 cup of glue with 1/2 cup of water and mix until it’s fully combined
  3. Add your sprinkles, your sparkles, your food colouring until you’re happy with the colour, the sparkle and the shine.
  4. Pour the glue into the borax mix. We tried 2 batches and 1st batch we poured glue into borax, 2nd batch we poured borax into glue. 1st batch worked better, so not sure it really matters but that’s what we found. You’ll notice straight away that it starts to polymerize* which is very cool.
  5. Stir like there’s no tomorrow. Get those biceps working and really stir it. Try and get as much of the borax/water combined with the glue as possible. Keep stiring, keep stiring!
  6. Eventually you’ll see it come together enough that you can put it on the table and start kneading it out. Don’t worry if there’s a bit of excess water, just tip it out.

What did we learn?

The two main concepts for slime science are polymers and Non-Newtonian Fluids. The white glue in our slime is a polymer, a large chain of molecules that allows it to be poured. When we add the borax it changes the structure of the chain making the polymer thicker turning it into our awesome slime!

A Non-Newtonian Fluid is neither a true liquid or a true solid. You can pick it up like a solid. However, it will begin to flow like a liquid and will also take the shape of the container.

Here is an easy to understand pdf about the Science of Slime

The Rules of Slime (as I told my daughter)

  • Slime is for outside, it’s messy and sticky but also lots of fun for OUTSIDE play!
  • It’s for “big kids” only to play with, which for us means you have to be over 4. Borax in such small quantities is fine to play with but NEVER to be eaten, so don’t leave slime around kids who are likely to put it in their mouth.
  • When you’ve finished playing with it store it in an air tight container. We use glass jars but a sambo bag would also work.
  • Always wash your hands when you’ve finished playing

  • polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks.

    Hi Roxy. Some results for for you and any one else who tries it… We followed your recipe exactly and produced a bowl of white liquid. We stirred vigorously for five minutes which made no change to the very watery consistency. (Okay FAIL, now what?) So we poured more PVA directly into the solution and got a non-stretchy slime. A malleable plasticene substance that felt like liver and tore apart rather than stretching, like good gooey slime ought to.
    My 10 yr old daughter went for ‘take-two’ using only a tablespoon of the borax solution, a tablespoon of liquid soap, 1/2 cup of PVA glue straight-up. And huzzah! Success!
    Ahhh… kitchen table science experiments…

      Oh, I now see we are closer to your fluffy slime process.
      Will try that one next…

      Half the fun is in the experimenting!! I wonder if sometimes the brand of glue makes a difference? Glad you got there in the end. Got any photos??

    Is Borax safe to use.

    I can’t wait to try it once I get some glue but if it does not work I surely will be sad cause my parents rarely buy me that kind of glue cause at the store I go to it cost $7 and I normally use glue sticks at school so I normally don’t use the runny glue :3 May unicorns bless your day 🦄

    Hi im a child care educator, and love your experiments. We have followed this slime recipe twice now, me and my preschool class and have had no issues (we have had to add a bit more borax in but slight change) the kids love making it as its so easy and quick to do and we have instant results that they can watch.
    than you 🙂
