Galaxy Slime

Galaxy Slime is a fun and colorful way to let kids explore color mixing and spark interest in outer space.

My son loves playing with homemade slime, and we are always looking for ways to make different and interesting recipes. He loved creating the different colors, then watching them mix and spread. And the sparkly star confetti made it even more fun!

How to Make Galaxy Slime

Galaxy Slime

Add the glitter glue into a bowl and stir in 1/4 cup of water. Mix well.

Add a few drops of liquid watercolor to create the desired color. Add in the star confetti.

Pour in 1/4 cup liquid starch and stir to combine. The slime will start to separate from the sides of the bowl — remove it from the bowl and knead with your hands until it is no longer sticky and stretches easily.
