Make Your own Slime

Making Slime is soooo satisfying.

It is really cheap, really easy (on the whole) and really fun for all ages. Some people insist on wearing gloves when they mix up slime but the real joy in the experience is getting your hands in there and enjoying the ooze!

We've four recipes here for you to try. They are all tried and tested by playworkers

  • Simple Slime
  • Super Slime
  • Bouncing Slime (this one is the difficult one)
  • Free For All Slime


  1. Put any waste in the bin – not the sink.
  2. Ensure the surface you work on is wipe down, or use a piece of plastic you can throw away at the end.
  3. Wash your hands when you’ve finished ……
  4. Watch where the food colouring is going – it can really stain!
  5. This is fun because it’s messy so be ready to clean it up
  6. Scale up or scale down the ingredients as you need

Simple Slime

The easiest of the four recipes and great for younger children.

Food colouring (optional)
Mixing bowl/roasting tin, or whatever takes your fancy/needs
spoons (optional)

  •  Put approx ½ cup cornflour in the mixing bowl then add ¼ cup water.  
  • Mix, add a few drops of colouring.
  • When blended ( or even before) get your hands in there and experience the odd properties of your slime. How can it be squeezed into a solid then turn back into  liquid when you open your hands? Did you know you have created a Non-Newtonian Fluid?

Custard is a Non-Newtonian liquid - watch a Brainiacs experiment here

Super Slime

This is a drier but firmer slime than the simple slime.

White pva (use the children’s washable stuff.)
Food colour
Mixing bowl
Wooden spoon
Something to store your slime in  as it’s going to dry out quickly. Plastic take away cartons are good.

  •  Put approx ½ cup of the PVA into the bowl.

  • Stir the glue and gradually add the cornflour, a little at a time, put in a few drops of food colouring and mix until it feels right. Too much cornflour makes a really dry mix so go easy when you’re pouring it in!

  • Get your hands into the mix – if you haven’t already and watch it flow between your fingers, roll it and stretch it.

Bouncing Slime

This one is a little more complex but just fabulous – try using red food colouring, the horror fans will love the effect!

White children’s PVA glue
Cold water
Liquid starch (we mixed up some dry laundry starch with water)
Mixing bowl
Food colouring

  • Mix ½ table spoon of liquid starch with ½ tablespoon water in a mixing bowl.
  • Add 1 tablespoon of white glue to the mixture. Mix well for 1 minute.
  • Add another tablespoon of white glue to the mixture. Mix well for another minute.
  • Let the mixture stand for several minutes to thicken.
  • Pick it up in your hands and roll it about to get the stickiness off and allow it to dry off.
  • Now you can try stretching and bouncing it and comparing it to your other slimes.  What happens when you roll it onto newsprint.

Free for All Slime

Not everyone can be bothered with measurements. What happpens when you experiment and just mix it up?

Liquid starch
Children’s PVA
Mixing containers and spoons
Food colouring

  • Chuck the raw ingredients out on the table in containers.
  • Let the kids make up their own recipes – just like real chefs and scientists.
