After making our rainbow slime, the kids noticed that when you mixed the colors, it looked a lot like unicorn poop! And so, the unicorn poop slime was born. Learn how to make your own version of slime unicorn poop with these super-simple rainbow slime directions. It’s one of my kids favorite slime recipes to make! They ask to make it every few weeks, and I let them make it about twice a year. 😀
A word of warning, once you start mixing, the slime continues to mix colors until it turns brown.
If you want the slime to remain looking like unicorn poop, don’t handle it much after twisting the colors.
However, it will be inevitable that the colors mix and eventually, what you’re left with will look a little more realistic than you might be hoping for. 🙂
Learn how to make unicorn poop slime that will wow your friends and gross everyone else out! It’s so easy, and a blast to make!

Step by Step Directions to Make Unicorn Poop Slime
Here’s how you can make your unicorn poop slime a success.
We usually use one part glue, one part starch, and half a part water for our slime recipes.
After adding the coloring and glue, add the starch and stir.
Stir with a fork until you can’t stir any longer.
Let the slime sit for about 5 minutes.
Take out each color of slime and work it together with your hands to remove any remaining stickiness.
Stretch out the slime one at a time and arrange them in a rainbow pattern on a flat surface (a table or tray works great)
Twist the rainbow like you’re planning to make bagels out of it.
Swirl the swirl into a poop-like pattern.
You’re done!
Unicorn poop slime has been created.
If you don’t want the colors to mix too quickly, don’t form the slime into the poop shape until you’ve played with the rainbow a little while.
My kids loved placing their unicorn toys in the slime to play, although the implications of that are pretty gross, so don’t think about it too much. 😀
