Science Project: Eco-Friendly Halloween Slime

The slime craze is well and truly here! However, a lot of parents feel uncomfortable about children making and using slime, because many ingredients, such as glue, borax, washing-up liquid and contact lens solution, are full of chemicals, and exposure through the skin can be dangerous and toxic.

Eco Kids Planet Magazine has been testing a new eco-friendly slime, which works like a dream. It’s 100% non-toxic, made from natural ingredients, and completely edible and biodegradable. We’ve made this batch super-slimy, green and creepy for Halloween!


What you need:

  • Half a cup of cornflour
  • Cup of water
  • Natural food colouring (we used green)
  • Natural food decorations (we used icing eyes, cupcake sprinkles and jelly sweets)
  • Old plastic container (with a lid to store your slime)
  • Spoon and knife for mixing
  • Wipes (very handy to have these nearby)

What to do:

Step 1: Prepare an area that you don’t mind getting messy.

Step 2: Measure out half a cup of cornflour. Tip this into your plastic container.

Step 3: Add some food colouring to your cup of water. Mix together.

Step 4: Add about 10 spoons of the coloured water to the cornflour. Give it a good mix using a knife or spoon.

Step 5: Your mixture should now be rather crumbly. Slowly add some more coloured water to the mixture, one spoonful at a time, until you reach a gooey slimy consistency. You need to mix it after each spoon of water is added. If the slime is too watery, just add a little more cornflour. If it becomes too dry or crumbly, add a splash more water.

Step 6: Time to decorate! Add your favourite Halloween treats to make your slime creepy-crawly, spooky-wooky. Give it a good mix with your hands. Watch as the eyes and insects bury themselves and move under the slime... Cool!
