This was a HUGE hit with the kids.  Once we figured out how to make slime with glue and borax, the littles did this over and over again all summer.

A few tips when making DIY slime with glue and Borax: more Borax makes a more solid slime.  Less Borax makes a runnier slime.

Always make sure you mix the Borax in LAST.  Otherwise, you just end up with a clumpy mess.

Borax is relatively safe.  It's used as a stain remover and detergent booster in laundry.  However, it can be an irritant if you get it in your eyes, mouth, etc.  Adults should probably do the Borax step.

How to Make Slime with Glue and Borax

You can make slime with glue and borax and just a few other ingredients: water, food colouring, and any optional add ins like glitter.

Ingredients for Slime

  • 1 oz of white glue
  • 1/4 cup water
  • a few drops of food colouring
  • glitter, sequins, etc. (optional)
  • 1/4 cup (or less) Borax

We used 1/4 cup of water and 1/4 cup of Borax and our slime turned out quite solid.  (We put it in little jars and the kids loved that they could push them down into the jar and make farting sounds!)

If you want slime that is more liquid-y, just use less Borax.  You can experiment to get a texture and consistency that you like.

Instructions (How to Mix Your Slime)

The order that you mix ingredients when you are DIY'ing your own slime is crucial.

If your Borax touches the glue or the water before you mix the latter two together, you'll just end up with a clumpy mess.

Moral of the story: mix the Borax in LAST.  Don't reuse your measuring cup after it's touched Borax.  Clean it first.

  • Add water and glue to your mixing bowl and mix well.
  • Add food colouring and any other add ins you want.  Mix until you have a runny glue mixture with no lumps.
  • Add Borax at the very end, once everything else is mixed well.
  • Mix, mix, mix.
  • Slime!  Hooray!

  1. My daughter has been talking about how she made slime at school all week!
    If I would have known it was this easy we would have been making our own. I already have most of the supplies that I will need, so that’s a plus.
    Science is an amazing tool for young minds and I am thankful I came across this. I am constantly trying to find new things I can do with my daughter that helps with learning and creativity.
    Thanks to this we will have many great times making some slime and coming up with new concoctions. Thank you for the great info and I look forward to reading more on your website!

    1. Thanks for stopping by Timm.  My kids also LOVE slime.  We’re trying out a whole bunch of different recipes.  I think this one is one of the easiest.  🙂
