Make magical DIY unicorn slime!

Published on September 8, 2026 by Holly Butteriss

Sonia and Caverleigh - the amazing makers behind The Craft Aisle, are multi-craft goddesses! This time they've put together this super simple step-by-step tutorial to make unicorn slime - magical to look at and so much fun to play with!

3 x 5oz bottles of PVA Glue (1 bottle per colour)
2 tsp of baking soda
4 tbsp of contact lens solution. *It needs to contain boric acid and sodium borate in the ingredients.
2 tbsp water
Neon food colouring (3 colours)

Make your slime!

1

Pour all 3 bottles of glue into a bowl.

2

Add 2 tsp of baking soda and mix well.

3

Slowly, mix in 3 tbsp of contact lens solution.

4

Add 1 tbsp of water.

5

Mix until your slime comes together. If it’s still a bit too sticky, add a bit more contact lens solution and water. We added in an additional tbsp of each!

6

Remove from bowl and knead until your slime forms.

Pro Tip

You can put lotion on your hands to help prevent it from sticking as you knead!

7

Separate the slime into 3 separate sections.

8

Add a different colour drop of food colouring to each section and knead to incorporate the food colouring, creating 3 separate solid colours of slime.

9

Twist all the slime colours together to make one multi-coloured ball of unicorn slime!
