Add food colouring to achieve your desired colour (about 6 drops).
Once the red food colouring is completely combined, add a bit of red mica powder (we used a purple red shade here).Stir well, until the powder is completely combined.
Step 3: Activate the slime
Activate the slime by adding 2-1/4 teaspoons of contact lens solution.
Stir the mixture until you can’t anymore and it starts to pull away from the sides of the bowl. Press the mixture down to incorporate all the contact lens solution.
Pick up the slime out of the bowl and work it in your hands – stretching, kneading, and rolling.It’ll be sticky at first, but don’t panic! Continue working it and using the slime to clean itself off your hands.
Continue until the slime no longer sticks to your hands. You can add a couple more drops of contact lens solution if it’s still a bit too sticky.
