Ingredients Needed to Make Galaxy Slime Recipe
- 3 – 6 oz bottles of glitter glue
- 3/4 cup water, divided
- 3/4 cup liquid starch, divided (also called laundry starch)
- silver confetti stars
- liquid water colors — we used a variety of colors: purple, magenta, and teal
- Something to stir with like a plastic spoon or craft stick
Directions for Homemade Galaxy Slime Recipe

Step 1
Add the glitter glue into a bowl and stir in 1/4 cup of water and mix the glue mixture well.
Alternative: Use clear glue and add your own silver glitter.

Step 2
Add a few drops of liquid watercolor to create the desired color then add in the star confetti.
Alternative: Food coloring is always an option when making slime. We liked the watercolor paint for this one because of the vibrance.

Step 3
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.

Step 4
Repeat the slime making process with the remaining colors and ingredients to create three different colors of slime: blue, pink, and purple.

How to Store Your Own Galaxy Slime
Use an airtight container to store your DIY galaxy slime. I love using leftover clear plastic food containers or a small zipping plastic bag. Generally homemade slime will last for several months if left in a sealed container at room temperature.
