Rainbow Glitter Slime

Kids have gone crazy for slime, they can’t get enough of it! Here’s a safe and easy-to-follow recipe from the new book, Super Slime! This amazing recipe uses Transparent Slime as a base with lots of different coloured glitters to create a beautiful rainbow effect, which you can then mix into pretty swirling patterns.


Super Slime!


You will need

½ cup (120ml) clear PVA glue

2 tablespoons water

½ teaspoon baking soda (bicarbonate of soda)

Glitter in all the colours of the rainbow (red, orange, yellow, green, light blue, dark blue, and purple)

About 1 tablespoon slime activator (eyewash or contact lens solution)

Medium mixing bowl

Measuring cup or pitcher (jug)


Mixing spoon


Small cup

Pipette/dropper (optional, but fun)


Making Transparent Slime

1. Pour the PVA glue into the bowl and add the water and baking soda. Stir well until everything is thoroughly mixed together.



2. Add the activator to the small cup. Use the teaspoon or a pipette/dropper to add the activator to the mixture a bit at a time. Keep stirring as you do this. The mixture will gradually get more stringy and start to come away from the sides of the bowl.
3. Keep mixing in the activator, a little bit at a time, until the slime reaches the consistency you want - the more activator you add, the firmer the slime will become.
4. When the slime is ready, put a few drops of activator on your hands, then pick it up and start stretching and folding it. It might be a bit sticky at first, but will become soft and stretchy, and lose its stickiness, as you work it. Put a little more activator on your hands if the slime still feels too sticky and keep kneading until it reaches the consistency you want.



Top tip: The amount of water and activator you need to add will depend on the make of glue you use. If your slime doesn’t come together easily, add some more glue and a little more activator. Remember that making slime requires you to experiment.



Making Rainbow Glitter Slime

1. Take about 1 tablespoon of the transparent slime, put it onto the countertop, and mix in 1 teaspoon of red glitter. Use your fingers to knead the glitter into the slime until it is well mixed, and set aside.

2. Repeat for the remaining colours of the rainbow—orange, yellow, green, light blue, dark blue, and purple. It doesn’t really matter which colours you use or in what order!

3. Line up all your blobs of glittery slime, so they are just about touching each other. Pinch the blobs together with your fingers and thumb to make one long strip of slime.

4. Hold the strip of slime at each end and slowly lift it up from the countertop, so it stretches into a beautiful, glittery, rainbow-colored sheet.

5. Now let the sheet of slime go and gather it into one big lump. Twist the slime around gently so the colours swirl and flow together.


Let’s investigate: How long can you keep the colors of the rainbow slime separate before they all blend together? What color does your slime end up?
