Ingredients Needed to Make Galaxy Slime Recipe
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.
Our Experience Making Galaxy Slime

Step by Step Pictures of How to Make Slime
Here is a picture summary of the steps to making slime the easy way.
First Time Making Slime?
What ingredients do I need to make slime?
This is typically the first question people have. The basic ingredients for a simple slime recipe often include school glue (PVA glue)- we use glitter glue in this slime recipe, a slime activator (like borax solution, liquid starch, or saline solution containing boric acid and sodium borate) – we used liquid starch, and some water. Additional elements can include food coloring, glitter, or scents for customization.
How do I make slime without borax?
Due to safety concerns with borax, many people look for alternative activators. Solutions like baking soda and contact lens solution (which contains boric acid and sodium borate), liquid laundry detergent, or cornstarch recipes are often cited as substitutes. We use liquid starch in this slime recipe because traditionally liquid starch is made of vegetable products. You can check your packaging to see what your liquid starch ingredients might be.
Why isn’t my slime forming?
This is a common issue for first-timers if the slime isn’t turning out as expected. The problem could be with the proportions of ingredients, the type of glue used, or the activator. Some troubleshooting tips may be required, such as adjusting the amount of activator or ensuring all ingredients are mixed thoroughly.
How do I get the slime to the right consistency?
Achieving the perfect slime texture can be tricky. People often need to know how to thicken slime if it’s too runny (usually by adding more activator or glue) or how to thin it out if it’s too stiff (usually by adding warm water or lotion).
