How To Make Slime Recipe With Borax

Easy science experiments for kids often don't need many ingredients, and slime is no exception.

But borax can be a little hard to track down; you'll find it in the laundry section of your grocery store or Walmart. For the UK the best place for borax is Boots.

Home School Science Recipe

  • 4 ounce (110g) bottle of white glue. Elmer's (PVA) works best for some reason.
  • Half a teaspoon (2.5 ml) borax powder.
  • Distilled water.
  • Food coloring.
  • Three disposable plastic containers - yogurt pots work fine.

Easy Slime Recipe Instructions

  1. Get out the homeschool newspaper. Kids experiments are often bad for the carpet.
  2. In one container, stir the borax powder into 250ml distilled water until it dissolves.
  3. In the next container, mix 250ml distilled water and the glue together.
  4. Get another plastic container and mix the dissolved borax powder and the watered down glue.
  5. You should see some genuinely bizarre home school science substance forming as the slime begins to appear. Get your kids to add a few drops of food coloring for even more fun.

However, a word of warning. We found the ratio of glue to water in the slime recipe a bit fiddly to get right; you may have to get your kids to add a bit more glue to make the slime form. If you're struggling, I've seen another recipe for how to make slime with borax using:

  • 1 tablespoon of glue to 1 tablespoon of water
  • 1 teaspoon of borax to 1 tablespoon of water

But then I suppose the idea of home school science is all about using experiments to find things out, as you'll see if you look at our kids science page.

Home School Science

Easy science experiments are perfect for proving all sorts of interesting scientific facts, and you've just proved that by learning how to make slime.

The homeschool science is based on messing around with states of matter.

What you've shown is that slime is a weird substance that breaks all the rules because sometimes it acts like a solid and sometimes it acts like a liquid.

If you want your kids to really impress their friends with how much you learn in home school science, tell them they've just made a non-Newtonian fluid. Experiments can be pretty cool...

How To Make Slime Recipe Without Borax

Making slime doesn't need borax; you can make an easy version by getting your kids to do experiments with cornstarch (corn flour) to make a similar substance. This is also great for home school experiments with young kids as it doesn't take much preparation and you'll likely have all the recipe ingredients in your kitchen.

Kids Gak / Oobleck / Ooze / Quicksand Recipe With Cornstarch (Corn Flour)


  1. Measuring cups
  2. Quarter cup (65ml) cornstarch (corn flour)
  3. Quarter cup tap water
cornstarch mix

All you need for this easy recipe is to put the cornstarch in a plastic cup and get your kids to add the tap water, a little at a time.

Warning. Go slow on this; you don't want to add too much water to your recipe. You're trying to make a very thick mixture.

Now pour the gak, oobleck, ooze, quicksand or whatever you want to call the cornstarch recipe onto your hand. It should be easy to pour, but when your kids stick their fingers in you'll find it instantly turns hard.

Once again, you can astound everyone with the wonders of home school science experiments! You've made something called a colloid which changes form under pressure, so it appears like a liquid but also like a solid when you push down with your finger.

If all these experiments are awakening your curiosity, Wikipedia has a rather mind-boggling explanation for non-Newtonian fluids.

I have to say I have performed easy science experiments over supper using a recipe involving custard powder - being full of cornstarch it works just as well!

If home school science is beginning to sound appealing, don't forget we have lots of other easy kids activities to try.
