Unicorn slime is a glittery clear slime in several pastel colors (pink, purple, blue) twisted together. Little Bins for Little Hands makes it with liquid starch, but notes that the saline solution recipe works too: that’s the one we give here, so you can use the same contact lens solution activator as in all our recipes.

The catch: the more you play, the more the colors blend, until it ends up a glittery purple-gray. That’s normal, and it still looks pretty.

Ingredients

For each color: ½ cup (120 ml) clear PVA glue, ½ cup (120 ml) water, ½ tsp (2.5 ml) baking soda, 1 tbsp (15 ml) contact lens solution (boric acid + sodium borate)
Pink, purple, and blue food coloring (one drop of each)
Iridescent glitter and sequins

Supplies: three bowls, a clear jar.

Need more or less? Recalculate the amounts for this recipe to fit your bowl or the number of kids.

Why these ingredients? What the activator does and which glue to choose.

Steps

In each bowl, mix glue and water, one drop of food coloring, and some glitter.
Add the baking soda to each bowl.
An adult adds the solution a little at a time to each bowl; knead each color separately.
Lay the three ropes side by side, stretch them together, and twist two or three times.
Store in a jar with the colors still showing.

The most common slime fails

The colors blended together: Twist less. To get crisp colors back, you’ll need to make separate batches again.
One color is stickier than the others: Each bowl gets its own amount: an adult adds a few drops of solution only to the color that’s sticky, before you twist the colors.
