ALL ABOARD: WE’RE GATHERING STEAM

Teachers love apples, and kids love slime! Learn about the chemical bonds that form when you mix glue and the activator together.

You’ll need:

  • 2/3 cup Elmer’s Glue
  • ½ tsp baking soda
  • ¼ cup water
  • 5 TBSP contact solution
  • Apple essential oil (if you want it to smell yummy)
  • Red food colouring
  • Bowl
  • Spoon
  • Gloves (if desired)

Instructions

  • Add glue to your bowl
  • Add water and baking soda, mix
  • Add food colouring (and essential oil if you like), mix
  • Add the contact solution (this is your activator)
  • Mix and knead until combined.

Slime is so much fun to play with, but it is also scientifically cool!

Why is slime a chemical reaction?

Polyvinyl alcohol can be found in simple PVA glue and borate ion is created when baking soda and contact solution are mixed. Once these household ingredients are mixed, they cannot be changed back, making it a chemical reaction!

If you try this slimy fun at home, don’t forget to share your creation with us on social media @childmuseumwpg
