Unicorn Spinkle Slime

This tutorial shows you how to make the best unicorn slime

This DIY Slime is the perfect activity for a science craft.

Slime is a great sensory activity for Kids of all ages.

What happens when you make slime?  Apart from a gooey mess I mean. The glue has an ingredient called polyvinyl acetate, (PVA Glue)  which is a liquid polymer. The borax or liquid starch depending on which you use connects the polyvinyl acetate molecules to each other, creating one large conjoined flexible polymer.

1/2 cup of water

1 cup of clear glue or 1 cup of white school glue

Metallic Acrylic Paints Silver, purple and blue

2 tbs of cake sprinkles.

Disposable Plastic Cups and spoons

1/2 cup of liquid starch (laundry section of Supermarket)


Pour the glue evenly into 3 separate plastic cups (one for each color), add a squirt of paint in each and mix well with the spoon.

Add your liquid starch to each cup a teaspoon at a time. Work with one color at a time only.

You need to work fast as the slime will start to form immediately. Stir for about 20 seconds, then take out of the cup and start kneading the mix, it will be sticky at first but will start coming together.

The mixture will start to thicken immediately. If it is still sticky add a few more drops of the liquid starch, keep doing this until it all comes together.

You need to do this for all 3 colors. Then lay out the slime in color strips. Then mix them together to form a stripey slime and throw in the cake sprinkles.
