Science Club Slime Recipe

In science club this week we made slime using child friendly ingredients that produced some excellent results. If you'd like to try is at home - here's the recipe:



PVA or clear glue (also known as school glue)

Bicarbonate of Soda 

Contact Lens Solution (make sure the one you buy contains boric acid in the ingredients list. It simply won’t work without this.)

Gel food colouring (Liquid food colouring alters the recipe and doesn’t work so well)



  • Tip 1 cup of the PVA glue into a clean bowl.
  • Then add 1 teaspoon of bicarbonate of soda
  • Mix them together
  • If you want to add colouring this is the best time to do it. Just a small blob, then mix it into the glue and bicarb mixture until it's evenly distributed. You could add glitter too if you'd like
  • Next add 1 tablespoon of contact lens solution
  • Mix with a spoon until it starts to become stringy, coming away from the edges of the bowl
  • At this stage take it out of the bowl and knead it between your hands. It will start off sticking to them but within about 20 seconds it will firm up and stick only to itself, becoming elastic and super stretchy
  • ENJOY!
