Pour about eight tablespoons of school glue into a bowl.

Add a few drops of food colouring and mix with a spoon until the colour is fully mixed.

Stir in a couple of teaspoons of glitter. You can add Halloween confetti sprinkles and/or googly eyes if you like.

Squirt in about four tablespoons of shaving foam into the mixture and stir well.

Add a teaspoon of baking soda and mix again.

Add one tablespoon of contact lens solution to your mixture and stir with the spoon. Your mixture should begin to stick together. Continue to add a little more contact lens solution until the slime no longer sticks to the bowl. You can see it changing before your eyes - it's a pretty cool experiment at the same time as making slime!

Take the slime out of the bowl and knead and stretch it with your hands until it is no longer sticky.

Store in an airtight jar or tub. Add Googly eyes to the front!
