Adult Supervision Needed

Yes - The slime is formed by a chemical reaction between the polyvinyl alcohol (PVA) in the glue and the borate ion from the boric acid in the contact lens solution. We therefore recommend that the recipe is not altered, as the chemical reaction needs these ingredients to work. Please make sure that the making of the slime is supervised by an Adult. After making / playing with the slime we recommend that hands are thoroughly washed. This Slime is not edible. If your child has any allergies, please make sure you check the ingredients of each of the components. If any signs of reaction appears on the skin, please wash thoroughly and stop use immediately. If in doubt, please seek medical advice.

How to Make

  1. Pour approximately eight tablespoons of PVA glue into your mixing bowl. Add a few drops of red food colouring and mix with a spoon until the colour is fully mixed.
  2. Squirt some shaving foam into your mixture, approximately the amount of half of the glue, and mix it in. Then add a teaspoon of baking soda and mix it again.
  3. Add approximately one tablespoon of contact lens solution to your mixture and stir with the spoon. Your mixture should begin to stick together and feel thicker. Continue to add a little more contact lens solution until the slime is no longer sticking to the bowl.
  4. Take the slime out of the bowl and knead and stretch it with your hands until it is no longer sticky.
  5. Repeat steps 1 to 4 two more times, once using green food colouring, and once using no food colouring to create white slime.
  6. Twist the three colours of slime together to create a Christmas rainbow effect.
  7. Lay out your Christmas rainbow slime on a flat surface and add some iridescent glitter to it. Knead it with your hands to mix the glitter in.
