How to make green gooey slime

Impress your kids with this gooey green goo slime making activity. Green goo is a fun learning experience as they make their own slime with science. Kitchen science has never been this fun, so grab your ingredients and get gooing today!  

What you need:

  • 1/2 cup Elmer's school glue
  • 1/2 cup cold water
  • green food colouring
  • 5 tbsp Borax laundry detergent (found in the cleaning aisle of supermarkets)
  • 1 cup of hot water (just off the boil)

Number of players:


Put about 1/2 a cup of glue in a bowl, mix in half a cup of cold water.__

Add some drops of green food colouring. __

In a separate glass jug, dissolve a tablespoon of Borax into one cup of hot water. Add a few more teaspoons of Borax, a little at a time until no more Borax will dissolve into the water.

Add the Borax mixture to the gluey mixture and give it a stir. A blob should form in water. Pick the blob out and knead it until it takes shape as a sticky ball of goo. __

Remember it is to be played with and not eaten!

You can keep your gooey green slime in a resealable bag.
